Stainless steel plate to reduce welding stresses , should make the heating surface of welded joints kept to a minimum , some temperature as low as possible to reduce the scope and amount of weld shrinkage uneven heating zone , and the temperature of the weldment tends to be uniform as much as possible .
Using smaller welding specifications and methods of operation , you can receive a certain effect. For example ; the use of small diameter rod, multi-pass welding , small current rapid welding method does not swing ,
Instead of the large-diameter rod , single pass welding , high current slow swing bonding method ; low current , multi-pass , filaments automatic submerged arc welding , instead of high-current , single-channel , thick wire automatic submerged arc welding ; welding speed rapid gas shielded arc welding , instead of automatic submerged arc welding ; use temperature between the control layer , instead of the continuous welding method, etc. , these methods can make welding tensile stress to some degree reduced to a low hydrogen electrodes .
