Plasma welding system in the application of stainless steel pipe

   Advanced welding technology and the automatic matching of the plane with equipment can greatly improve product quality, increase productivity and reduce manufacturing costs and improve the working conditions of workers. However, the earlier domestic pipe production line is still in a relatively backward state, not the original due to a very good set of stainless steel pipe welding system, most manufacturers using manual TIG and manual arc welding, welding of these two methods of application stainless steel welded pipe production line there are many disadvantages: 1. plate groove weld preparation prior to the high cost; 2. Welding inefficient; 3. Because it is manual, welding quality can not be guaranteed the low rate of qualified products; 4. a large quantity of heat input , and so the workpiece deformation. In contrast, plasma welding as a result of energy concentration, can not groove, one can achieve single-sided welding of stainless steel 8mm double-sided shape, greatly reducing the pre-welded to ensure quality and improve efficiency. At present, the domestic pipe production capacity of 1660 × 104t, of which more than 70% remains in the backward mode of production equipment and processes, so to promote plasma welding system in stainless steel pipe industry is imperative.
