High Frequency Welding Machine , disconnected into two types, consecration Welding and acquaintance welding:

1. What is the consecration welding, consecration Welding is one or added turns of the consecration allurement in the anchored animate pipe, multi-turn aftereffect is bigger than a individual turn, but the multi-turn consecration braid accumulation and accession added difficult. Consecration braid and the apparent of animate aqueduct apparent agreement is top efficiency, but acceptable to could could cause the consecration braid and the acquittal amid the tube, the accepted consecration tube to accumulate the apparent of the aqueduct 5 ~ 8 mm gap is appropriate. Consecration welding, the consecration braid is not in acquaintance with the animate plate, so there is no wear, the induced accepted is added abiding to ensure the adherence of the welding, Welding the apparent above of steel, bond formation, such as API accumulation Precision tube, basically in the anatomy of consecration welding.

2. What is the acquaintance welding, acquaintance Welding is a brace of chestnut electrodes and anchored animate aqueduct on both abandon of the contact, the induced accepted assimilation is good, high-frequency accepted of the two furnishings of absolute acquaintance with the chestnut electrode and get the best use of animate , So the acquaintance Welding of top ability and low ability consumption, accelerated low-precision aqueduct accumulation is broadly acclimated in the accumulation of decidedly blubbery animate aqueduct about aswell charge to use acquaintance welding.

But the acquaintance HF Welding has two shortcomings: First, the chestnut electrode acquaintance with the animate plate, abrasion quickly; the additional is due to the apathy of the animate apparent and the bend of the bluntness of the appulse of poor acquaintance accepted Welding stability, centralized and alien bond brier college , In the Welding of high-precision and thin-walled tube is about not used.

Welding components are high-frequency welding induction coil, induction coil made of hollow copper tube, cross-section is round or square. Welding the middle of the cooling water, in order to guide the heat away from the High Frequency PVC Welding Machine, to avoid burning copper. Induction loop often made with both ends of the ring and upward tilt, the middle of the structure to stay narrow, so that energy concentrated in the middle, tilted at both ends to avoid affecting the other adjacent teeth.

High-frequency welding machine is based on the principle of linear current magnetic field formation, in the narrow line of narrow concentration of the most intensive magnetic field lines, magnetic lines through the conductor, the current should be generated, the conductor itself has resistance, thus making electricity into heat, heating conductor. Induction coil connected to the high-frequency power supply, the induction is also a high-frequency alternating magnetic field. The higher the frequency of high-frequency current, the more intensive the current in the conductor surface, so high-frequency heating surface temperature rises quickly, often a few seconds to dozens of seconds to make the solder temperature to achieve the required welding temperature.

High Frequency Welding Machine induction coil gap produced the most intensive magnetic field lines, the narrower gap, the more concentrated energy, equipment, the higher the efficiency, the faster the temperature. General saw welding used high-frequency welding machine power of 10 ~ 30kVA, oscillation frequency of 20 ~ 150kHz. Welding process, due to induction loop and sawtooth gap is very small, so pay attention to adjust the position to avoid the induction coil and the base and jagged contact with the other sides of the gap is consistent, otherwise it will cause side of the heat, while the temperature phenomenon.

The accretion action that grew out of accelerated adjustment provides an able way to aftermath circuitous work, including locations with anchored apparatus and even locations bogus from antithetical metals.

To cuff how abutting accretion accomplishment is to acceptable a boilerplate advantage for authoritative metal parts, it is absorbing to agenda this detail: Accelerated accretion accomplishment machines from Fabrisonic of Columbus, Ohio, are programmed appliance a machining center’s CAM software.

Specifically, the machines are programmed appliance PowerMill software from Delcam. With the software company’s help, Fabrisonic wrote a bore (SonicCAM) that about turns the CAM algorithms inside-out. Instead of breeding paths that abolish material, the bore generates paths that add material.

These aforementioned machines use accustomed machining apparatus paths as well. A amalgam access to allotment assembly combines accretion and subtractive processing in one machine. The accelerated action builds metal workpieces by fusing and stacking 1-inch-wide strips. Then, breadth the architecture of the allotment calls for accomplished detail, a CNC milling arbor enters into the cycle.

Using accretion and subtractive processes calm in this way overcomes assorted problems that potentially absolute accretion The best high frequency welding machine. First, locations produced this way do not necessarily charge consecutive operations. On this machine, the aeon can actualize a able part. Second, putting down the absolute in 1-inch-wide strips enables the apparatus to accomplish a body amount of 20 to 60 cubic inches per hour (depending on allotment complexity). This fast body amount agency locations can be created quickly, starting with just a ball of material. To accommodate for such big parts, the bigger Fabrisonic apparatus offers a plan envelope of 6 by 6 by 3 feet.

Why Use RF Welding?

There are several alternatives to RF welding including sewing, gluing, or using hot air. Why use RF welding?

RF Welding vs. Sewing

RF welding provides a consistent air tight seal unlike sewing. When sewn seams are stressed, the thread takes the pressure and could break. RF welds evenly distribute stresses throughout the material providing a much stronger seam while preventing any air, moisture, or debris getting in.

RF Welding vs. Gluing/Adhesives

Gluing can provide an air tight solution, but gluing takes much longer than RF welding and often uses hazardous solvents that are harmful to the environment. Glued seams are also subject to failure once the adhesive has worn out.

RF Welding vs. Hot Air

Hot air is a method that applies heat to the outside of the material to melt it and create a bond. This method is only effective up to certain thicknesses. Materials that are too thick will not bond in the middle as the core will struggle to melt, while the outside layers are over heated or burned. RF welding heats from the inside out and is the best method for forming air tight seams.

China's current construction market to use HF Welder the steel connection methods are: steel banding lap, mechanical cold extrusion connections, steel resistance welding, steel flash butt welding, steel arc welding, steel bar electroslag welding, steel gas pressure butt welding, embedded parts Steel submerged arc pressure welding, threaded pipe connections. At this stage the most important methods used are: lap, flash welding, electroslag welding, pressure welding and threaded connections and other methods of reinforcing steel connection. In this case,
For the above several commonly used steel connection method, the overlap method is not discussed with the elimination method; flash welding qualified rate is the lowest, about one-third of unqualified; electroslag welding times low, especially after welding ESW welding, Qualification rate is too low can not do testing test, so the electroslag welding can only be used for vertical welding of steel, can not be used for welding in other directions. The highest rate of qualified air pressure welding, fully able to achieve 100 percent pass rate; several welding methods, the cost of the highest thread connection method, about 20 times the cost of air pressure welding. If the calculation of electricity consumption, air pressure welding method costs about 0.3 yuan / head or so, if not calculate the electricity consumption, flash welding the lowest cost. If the investment from the device to see: the minimum input cost is a threaded connection, and some thread casing equipment manufacturers as a result of high cost of threaded casing joints, so leased to the user free of charge steel buckle machinery. Followed by pressure welding into the cost of small. Because flash welding and electroslag welding are required with a large welding machine, the input cost is followed by flash welding, electroslag welding. In this case,
From the above characteristics of the use of several devices, the flash welding welding operation is simple and easy to grasp, low cost of steel joints. Shortcomings can only be used for horizontal welding of steel, equipment, larger, mobile inconvenience, a narrow space or no crane can not be constructed, the joint pass rate is low, large power consumption; welding slag welding is characterized by lightweight, Convenient, easy welding operation, the joint cost is low. The disadvantage is that the vertical welding can only be used for reinforcement, need to be equipped with large welding machine, power consumption; thread connection method of operation is relatively simple, environmentally friendly equipment construction. The disadvantage is that the connector cost is too high. Pressure welding is characterized by the ability to weld horizontal, vertical, arbitrary direction of the steel, reinforced joints qualified a higher rate, easy to move smaller fixture, joint low cost, small equipment investment. The biggest drawback of pneumatic welding is the technical requirements for the operation of workers higher, the quality of welding by the workers in the technical level of a greater impact. However, the Ministry of Construction in 2003 promulgated the "Reinforcement Welding and Acceptance Rules" home page, which Article 4.6.2 of the gas welding welding method requirements: In recent years, due to the success of melt pressure welding and application, add the provisions of this article . The use of melt pressure welding, can simplify the end of the processing of steel demanding requirements, easy to operate, ergonomic high, so the provisions in the general case, should be preferred. According to the site site trial and error, this new melt pressure welding process is indeed more common than before the use of solid-state welding method is easy to grasp, and eliminates the need for grinding the end of the process, not only simplifies the operation process, A substantial increase in welding speed, a thorough and effective solution to the operator of the technical requirements of higher issues. In this case,
Japan has a certain understanding of the construction steel connection method, the highest rate of gas welding, so Japan is about more than 70 percent of the use of air pressure welding method. Many users of large companies in the country, after contrast test commonly used welding method of steel welding, welding all the advantages and disadvantages of welded steel, the conclusion is that the overall pressure welding welding efficiency is better. In summary, the construction of steel welding method, the pressure RF Welding method of integrated characteristics of the better.

PVC Welding is a action which involves accumulation of two abstracts together. Usually done in cases of metals, adjustment is done with the advice of calefaction to cook the aqueous ends and accompany them calm by abacus fillers to the aqueous part. Gas adjustment as the name suggests makes use of assorted affectionate of gases and oxygen to burn a torch. Aswell accepted as oxy-fuel welding, the a lot of accepted gases acclimated in this action are Propane, MAPP gas, accustomed gas, acetylene, abounding petroleum etc. Anyways the a lot of accepted gas acclimated in this action is acetylene. This action was developed in 1903 and is today acclimated in adjustment of pipes, tubes and is aswell acclimated in acclimation metals.

When it comes to blazon of metals which can be abutting application this adjustment – about all the metals can be anchored application gases. The alone point to bethink is that not all the metals cook at the aforementioned temperature and appropriately one needs to accumulate this point in apperception if resorting for the adjustment process.

Fuels used:

As mentioned earlier, acetylene is the a lot of frequently acclimated ammunition in gas welding. Other accepted fuels are butane, propylene, gasoline and hydrogen. These fuels are usually alloyed with oxygen to advance calefaction and cook the metals. If oxygen is alloyed with the ammunition the action is accepted as blaze and is populary referred as combustion.

One needs to consistently accumulate in apperception that anniversary gas has an altered acreage of its own. Appropriately one gas can not be acclimated in all the purposes as its calefaction backdrop are altered compared to the others. Accordingly one needs to yield aspects like the blazon of metal as able-bodied as the backdrop of the gas to adjudge if an accomplished bond can be created.

Equipment used:

A archetypal adjustment accessories makes use of both oxygen as able-bodied as ammunition gas to activate the process. Powered with two hoses and two burden regulators for anniversary source, the adjustment appartus works Radio Frequency Welding Machine with the bake to bond the materials. In cases area portability is an issue, the torches are fabricated with pressurized aqueous fuels so that the amount on the accessories can be brought down. A regulator is aswell acclimated to ascendancy the burden from the hoses of the tanks. The user accordingly controls the breeze of fuels with the regulator in both the corrupt as able-bodied as in the cylinder.

There are several types of welders to accept from and it all depends on what blazon of adjustment you do as to which HF Welder you choose:

Oxyacetylene Adjustment -- this is a bake and it burns a mix of oxygen and acetylene gas. The calefaction gets to 6,300 degrees Fahrenheit in a lot of torches like this. You can use this to solder, bond or braze. Sometimes these are acclimated to cut some types of steel. This is about the aboriginal blazon of adjustment a apprentice will do and the aboriginal welder they will use.

Stick / Arc Adjustment (SMAW) -- this blazon of welder works with an electrode alleged a "stick" and it creates an arc with the adjustment material. It works by putting the stick central the machine, the stick melts and it produces actual as accompaniment in the weld. This is a difficult blazon of welding, so the welder itself may be difficult to use and ascendancy for the beginner.

Mig Adjustment (Wire augment / GMAW) -- this arrangement aswell uses an electrode that is fed in a wire, pushed through a gun and it makes a bond puddle. They use either a careful gas or a wire cored with flux. Many humans use these types of welders for home projects and they are calmly begin at accouterments stores. This one is simple to use.

Tig Adjustment (GTAW) -- this blazon of adjustment aswell uses an electrode but it is acclimated with a cloistral gas (inert) which makes a bond puddle. It uses a adjustment rod aswell that makes a bond bean if a rod is ashore in the arc. This makes acceptable welds and is a college akin of welder.

Commercial welders may be a beyond apparatus that does the aforementioned as duke captivated ones but on a abundant beyond scale.

Before you acquirement any PVC Welding it is a acceptable abstraction to analysis the Internet for reviews of the altered types of welders to get an abstraction of their amount and how they are used.

The biggest cost component in the making of any PVC Welding table is the thick steel top. But a 1.6mm gauge sheet metal on top of marine ply should suffice. This relatively thin sheet metal is more to protect the top of the ply wood from all possible spatter and hot sparks that emanate during the welding operations.

The ideal height of a welding table is 900mm high and this height would be right for all welding operators. It will be helpful to fit castor wheels to the bottom of the legs for easy movement of the welding table inside the workshop.

Materials needed to construct a welding table:

* Metal top of 1.6mm sheet metal to size 832x1195mm for use as table top surface

* Marine ply or some similar flat wood for table top, of the same size as the sheet metal

* Legs are 40x40x3mm box section

* Castor wheels - 4 nos.

* Iron angle for the underside of the table preferably 40x40x4mm

* Mesh for shelf beneath the table top

* Iron angle to size 25x25x3mm for using around the top ply edges

* Small length of 5mm diameter rod of half meter length

Procedure to construct the welding table:

* Cut down the marine ply to match the size of the sheet metal top. Chop up some angle iron that will be welded up so that it can be bolted to the underside of the wooded table top. Cut two angle irons to 632mm length and two other 995mm length and these will make up the underside frame of the table top.

* Lay out your four bits of angle on the workshop floor. All the cuts have to be at right angles. You will need to cut them at 45 degrees so that when you weld them together, the height will be flush. On the particular abrasive chop saw loosen the two bolts and adjust the angle to 45 degrees. Once that is done, trim the ends at 45 degrees.

* Get the angle grinder and clean up the cuts and make them fine and smooth so that when the pieces are butted together, there will not have any problems. Lay out the four pieces again and tack-weld them together.

* Once the four corners are tack welded you will need to check the whole thing for square and flatness. Check the corners with a square to make sure that they are at perfect right angles.

* Next, grind down the weld beads on the top flat angle surface. Some holes will have to be drilled around the frame to facilitate screwing the timber top to the bench.

* Now make up the shelf frame to consist of four pieces of the 40x40x3mm box section steel welded into a rectangle of the same dimensions of the top frame. Finish them off with a grinder to get the burrs and metal shavings off the cut face. Go to clamp and weld the frame up.

* Lay out your four lengths of steel and tack-weld them in all four corners four times. This frame should not be fully welded as the legs have to sit on top of and underneath it. So leave the four tack welds in each corner and just grind them down.

* Cut to length four pieces of box at 500mm long. These will be welded onto the frame that that was just made. Next, you will tack weld the angle iron frame to the top of these legs.

* ake some mesh and cut it out to fit on top of the shelf frame. Chop the corners out of the mesh so that the legs can be welded on. The bottom legs will now need to be cut out. Again out of 40x40x3mm box. Only tack welds for now.

* Weld the mesh into its place. The mesh once welded will hold the frame tightly. If everything is perfect and hold square, weld it all up. A few small tack welds for each castor wheel should see them holding on tight. Get hold of the angle grinder and use the wire brush and go over the whole frame work of the welding table.

* Use an angle iron frame to go around the edge of the Automatic Blister Packing Machine ply top to protect the edge of the wood, and also to make it look more aesthetic. Tack-weld the top sheet of steel in a few places to the angle iron edge and do the vertical down welds for the edges of the angle iron.
