The seam (roll) welding special machine is the evolution of spot welder. It uses the roller electrode to replace the cylindrical electrode of spot welding and as the welding work piece moves between the rolling plates, the seal welding will generate weld nuggets which will overlap with each other so as to achieve welding effect. AC pulse current will be adopted. Roll welding is widely applied to light gauge welding of sealed container of oil drum, can, heating radiator, airplane and fuel tank, rocket and missile.

Features

1. 3-phase speed regulator controls the welding speed uniformly and without jerks.

2. Longitudinal and horizontal welding possible and is suitable for various jobs and working conditions.

3. Robust structure capable to withstand heat and maintain welding performance.

4. The rotation conductance or silver axis tile provides excellent contact and reduces electrical energy loss.

5. Versatile machine, applications ranging in Household appliances auto, and other metal working industries.

Machine Composition:
Main Body:Adopt the reinforced special designed steel structure as the main body. Vertical structure, powerful and stable intensity and this machine is equipped with slide way and all-directions water device. The bottom welding electrode is used to fix the cylinder so as to help fixing the mould and welding.
