Cantilever Backing Welding Machine
Using back welding to the welding seam bottom of the box beam is to prevent large current burning through bottom of welding seam; generally used the CO2 gas shielded welding.
And being similar with other structure, the cantilever back welding is composed of moving cart, column, cantilever beam, welding arm, welding seam tracking device, wire feeder, electric control system and the welding power, etc.
1.The dimension of the column is large, so it makes the overall rigidity structure bigger.
2.The main part of upper beam is square tubes and has light weight rigid good characteristic. The upper beams have guide and rack, so it makes dragging plate and welding beam moving levelly on the beam.
3.Two sets of motors drive four wheel axles through the gear. It composes 4 wheel driving systems, in order to make it stable and reliable operation.
4.The cantilever box beam welding arm has two groups of two welding seam. It can welds two welding lines simultaneously.
5.Usually we use Tangshan Panasonic CO2 welding machine( YD-600KH), also you can select other brand. Users can choose single arc single wire backing welding or double arc double wire welding according to their requirement.
