EN10219 EN10210 3mm Q235 Q195 Welded Black Round Carbon ERW Steel Pipe
Electrical resistance welding will be welders parts formed pressed between two electrodes, and subjected to current, the resistor thermal effects generated by the current flowing through contact with the workpiece surface and the neighboring regions to be heated to melt the plastic state, so thatmetal-binding method. Resistance welding methods are mainly four kinds, namely, spot welding, seam welding, projection welding, butt welding.
