Technical parameters

SHANGHAI DONSUN WELDING GROUP

For the bu - welding workpieces, through gas - liquid control, the

power is turned on and the workpieces are slowly pushed. The

oxida on and uneven protrusions on the surface of the welding part of

the workpieces are removed by flashing. Then, the end faces of the

welded workpieces are thermoplas cally processed. Subsequently, a

upse ng force is rapidly applied to make the two end faces penetrate

and weld together. This kind of welding features high strength, good

compactness, and there is no false welding, no inclusion welding, and

no pores. It is widely used for the bu - welding of handles of

tableware such as \"knives, forks, spoons, shovels\", as well as the

welding of hardware products like round pipes, square pipes, round

steel, flat iron, bicycle rims, motorcycle rims, and profiled materials.
