Welding system, used in long rough alliances and methods to control distortions and no termite treated soldiers in the operation of pipe additives

摘要

1. A method of limiting the twisting action of an additive (10) to a pipeline in use, in which the additive (10) includes a thickness edge extending longitudinally between the two halves of the additive and involves welding on each side of the additive, An average of one-third of the edges (31) in a pyramidal fashion, using an internal progression starting from one-third of the middle (31), along an equal contour of the edges (19),The outer part (37) of the edge is welded (20) and pushed outwards (19) from an edge point near an edge edge edge of the middle third part (31),And welding an edge (20) of the three-thirds outer part (37), using an end of the edge edge edge edge edge edge near the middle third part (31) to push outwards (19). Soldiers in each of these three sections include at least two layers of temperate welding technology to provide job release rather than conventional post weld heat treatment.
