AC spot welding of two different materials (0.25 thick stainless steel and galvanized steel plate with 0.6 mm thick) is taking off, how to solve?
Dissimilar materials with different melting points are more difficult to weld, and they are galvanized sheet (zinc layer of various thickness). Try with soft specifications. The first discharge time is 8 cycles, and the 6 cycle between the second discharges is tried.
EWM cold arc welding may be considered
Dissimilar metal welding, one should take into account their melting point, and the two is to pay attention to spot welding machine selection and power size. Three, pay attention to welding electrode material, four is to adjust welding parameters, try several specifications. If you need help, contact a professional spot welder manufacturer.
