1. Use the roller electrode to replace the cylindrical electrode of spot welding
2.Generate weld nuggets to verlap with each other and finish welding of workpieces.
3. AC pulse current, amplitude modulation current, three (single)-phase rectification, medium frequency and high frequency DC can be available.
4. Roll welding is widely applied to light gauge welding of sealed container of oil drum, can, heating radiatior, airplane and fuel tank, rocket and missile. (the welding thickness is within 3mm of single plate. )
5.The seam/roll welding is composed of welding spots.
6.According to different overlap of the melting cores, it could be divided into roll spot welding and air-tight seam welding.
7.Three stages in the forming process: pressurization, heating fusing and cooling crystallization.
Petrochemical container made from stainless steel, carbon steel, aluminum, brass, titanium alloys, etc. Or circular seam welding of pipeline, flange, automobile silencer or hardware product.
