About stainless steel welding deformation
For welding of grade 304 stainless steel, the current can be adjusted a little, not preheating, to prevent deformation after welding, the welding sequence should pay attention to, such as left -- right -- in the welding line, avoid welding head, to prevent warping.
In fact, the deformation of stainless steel and carbon steel caused little difference, but the deformation is greater than carbon steel, the treatment method is the same.(1) using smaller welding rod and smaller current.(2) correcting welding sequence;(3) before welding, clamp the weldment to avoid warping.(4) avoid excessive cooling or preheating of base metal.(5) the welding penetration is low.(6) reduce weld gap and reduce slotting degree.(7) pay attention to the welding size, not to make the welding bead too big.(8) pay attention to the fixed measures to prevent deformation.
