GTR Manufacturing has an experienced spot welding department. With our knowledge and attention to cost, we can weld your parts at a very competitive price.
Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. It is used to weld/fuse two pieces of flat materials together without the need to weld, rivet or screw parts together.
The process uses two shaped copper alloy electrodes to concentrate welding current into a small “spot”, simultaneously clamping the sheets together. Forcing a large current through the spot will melt the metal and form the weld.
