In the production of stainless steel carbon steel storage tanks, welding is a very important step, which is related to its product quality and use effect. However, in actual production, welding deformation often occurs, which is difficult. So is there any way to control welding deformation?

       The biggest difficulty in construction is the control of welding deformation. During the construction process, the equipment will undergo varying degrees of deformation due to prefabrication accuracy, assembly errors, and thermal expansion and contraction during welding. This deformation is mainly welding deformation. Welding deformation is caused by the rapid expansion of the weld when heated to high temperatures, and then cooling causes the shrinkage and bending of the weld.

       Stainless steel carbon steel storage tankThe welding deformation of stainless steel can be controlled by using small linear energy welding, reasonably arranging the welding sequence, using the principle of anti-deformation, rigidly fixing the fixture, and hammering the weld with a small hammer after welding.

       Things to note:

       During equipment manufacturing, it is necessary to ensure that all kinds of contamination that may carbonize the weld metal are removed before welding. On both sides of the weldment to be welded20mmThe surface (including the bevel surface) should be clean and free of grease, stains, paint marks, scale and other impurities. Usually acetone or alcohol is used for scrubbing, and if necessary, it needs to be polished first. If not cleaned thoroughly, these organic substances will decompose and burn into gas under the action of high-temperature arc, causing pores and carbonization in the weld metal, thereby reducing the corrosion resistance of the welded joint.
