In addition to high-frequency welding, there are also arc welding and resistance welding.
1. What is Arc Welding?
Arc welding involves melting the edges of steel plates through the heat generated by an electric arc and adding welding material to perform the weld. Arc welding is suitable for the production of welded pipes of various materials and specifications, but its production efficiency is relatively low.
2. What is Resistance Welding?
Resistance welding utilizes the resistance heat generated when current passes through the workpiece to melt and fuse the workpieces. Resistance welding has the advantages of fast welding speed and small heat-affected zone, but it requires a significant investment in equipment.
