Projection welding process is a one type of resistance welding.

Projection welding machine resistance. The dashed lines show the flow of welding current. We bring a wide range of Spot Cum Projection Welding Machines and Resistance Welding Equipments which are available in various models like TSP 30 TSP 50 TSP 75 TSP 100 etc. A typical resistance weld between two flat sheets left is compared to a projection weld right.

The wear is frequently mechanical abrasion. Projection welding schedules are available in the Resistance Welding Manual published by RWMAAWS and AWS Standard C11 Recommended Practices for Resistance Welding published by AWS. These include ceramic coated pins solid ceramic loction pins special pins silicon nitride Alumina nutting tools and sockets for testing.

Mostly in almost all applications with various small projections are molded on single parts surfaces which need to weld. The two pieces of metal to be joined are squeezed together by the electrodes on the welding machine so they are in good electrical contact. MACTERA trade mark was created for Resistance Welding and Riveting Machines at 2011.

Snow Co Tuffaloy Products Inc. In this projection welding is more or less similar of spot welding process. Resistance welding requires neither additional material or holes in the metal.

These three models DS309 DS310 and DS311 are synchronous and suitable for all type of THYRISTOR SCR controlled welding machines. Experienced and specialised engineering team of MACTERA serves customized machinery according to customer special requirements and products beside standard machinery about spot projection seam wire and butt welding machines. RWMA Class 2 is the first choice for electrode material in projection welding.

Capacitor discharge resistance welding is ideal for projection press-fit and annular ring projections up to 45 diameter. These machines are incorporated with Weld sequence controller sophisticated Quartz timer hold and off timings with singlerepeat cycle facility. The FlexFast welding packages can be easily customized to satisfy specific project and part requirements.

Best quality made in India Spot welding panel and Projection welding panel for new Resistance Welding machines and for old panel replacement. Coined or machined projections do not cause the same concerns as a stamped projection as there is no risk of premature projection collapse during welding. Projection welding is a resistance welding process of joining two sheets or a sheet and a thick component or a small component like nut to a big body like automotive chasis by making raised portions or projections on one of the components where weld nugget is required to be made.

Heat is generated mainly during the projection collapse thus the part containing the projection tends to be hotter. Projection welding reduces the amount of current and pressure needed to achieve a good bond between the two pieces with consequential less chance of shrinkage and distortion in the areas around the weld zone. Here are some example of the range of.

It is mechanically harder and more resistive to wear than Class 2. Then electric current is passed through them. Projection Welding is one of the most used types of resistance welding.

Projection welding is one kind of resistance weld where the shape or design of the part is used to make subtle point contacts to concentrate the current during welding. Projection Resistance Welding Machines The FlexFast family of welders offer the ultimate in flexibility durability and performance across a broad range of projection and resistance welding applications. Into the metal for the rivets or bolts to fit.

Low marking welds can be better achieved due to the minimal heat affected zone. As the name suggests Projection Welding is used for welding multiple projections on the workpiece. Projection welding is a resistance welding process for joining metal components or sheets with embossments by directly applying opposing forces with electrodes specially.

The most important variables of this assembly technique are the quality of the projections and the response of the cylinder as the projection collapses during the welding time. If mechanical wear and tear is a little heavy and Class 2 has to be faced too often try RWMA Class 3. In this process produces coalescence of welding metals the heat generated from electric resistance to current through the work piece hold together with pressure applied to electrodes.

All panels have digital Led display for timers and current. Projection Welding Prospot has the largest range of projection welding tooling available in the UK. How is a resistance weld made.

Projection welding has fewer variables that affect the resistance welding process as compared to spot welding. Our experienced technical staff will advise our customers on the most suitable solution for their applications.
