Introduction
Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current.
Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet.
Applications:
- Mild steel sheet, stainless steel sheet, galvanized metal sheet spot welding.
- Metal sheet fixing welding before continues rolling seam welding.
- Welding fan guard (with proper designed fixing and driving system), welding metal art ware, stationery, cook ware.
- With special made electrode, it can weld small mesh, birds cage, pets cage, condenser and similar work piece.
- Weld connection parts, the hinge, nuts and bolt welding, low carbon fasteners and stainless fasteners.
- Welding high conductive material, like aluminum, electrical contact, copper wire etc.(using Middle frequency power)
Single plate thickness:
- Uncoated mild steel sheet: 0.4-4.0mm
- Stainless steel sheet : 0.5-4.0mm
- Galvanized steel sheet (hot dip zinc, zinc5% aluminum, zinc55% aluminum and electrolytic ally deposited zinc coated steel sheets): 0.4-2.5mm
