Projection Welding Youtube. But in resistance projection welding RPW such flashes of light indicate poor welding. Just after a few milliseconds the weld is finished without heating up the surrounding area.
Resistance welding is a welding technology widely used in manufacturing industry for joining metal sheets and components. Our welding machines are designed to provide a production solution at an affordable price while ensuring reliability and low cost maintenance. Projection welding is a modification of spot welding in which the weld is localized by means of raised sections or projections on one or both of the workpieces to be joined.
While it can be also used to join thinner metal pieces together that tends to be a job left for spot welding.
In the early stages of welding the projection concentrates force and current into a small contact area. Projection welding is a modification of spot welding in which the weld is localized by means of raised sections or projections on one or both of the workpieces to be joined. But in resistance projection welding RPW such flashes of light indicate poor welding. The sparks you see are molten material being.
