 HWASHI Metal & Steel  Product seam welding series

• Use the roller electrode to replace the cylindrical electrode of spot welding

• It will generate weld n ets which will overlap with each other so as to achieve welding effect.

• AC pulse current or amplitude modulation current will be adopted, but three (single)-phase rectification, medium frequency and high frequency DC are also available.

• 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. In general, the welding thickness is within 3mm of single sheet. 

• The welding seam of roll welding is composed of welding spots.

• According to different overlap of the melting cores, it could be divided into roll spot welding and air-tight seam welding.

• There exist three stages in the forming process of welding spots: pressurization, heating fusing and cooling crystallization like spot welding.
