Mechanical parts than on a hard steel structure welded to a large, because to ensure the strength and stiffness requirements are sure to have welded parts, and the overall size, shape and position accuracy and workability of the late part is to have guaranteed. When carrying out welding repair of large and complex parts, must wear good and bad parts, repair welding process developed and strictly enforced.
Stainless steel welding
General case, stainless steel processing welding repair process should pay attention to the following three points:
1) preparation before welding: welding equipment is first must be prepared, followed by the more important is the preparation and welding groove weldment preheating.

2) positioning welding: when the local part of the whole has been broken off at the butt welding repair shaft parts, welded parts to ensure the accurate docking, to prevent excessive deformation during the welding process. For this reason, we should tack welding: spot welding method with a diameter smaller than the welding electrode, then correct the position again, in a number of symmetrical point, spot positioning.

3) post-weld heat treatment: In order to eliminate the residual stress after welding and reduction of cracks in the weld, post-weld heat treatment is a must.

These are the considerations when carrying out welding stainless steel processing needs attention, hoping to help to you!
