How to solve the stainless steel welding, stainless steel inside and outside surface blackening, yellow
On the back of argon to good protection, the stainless steel pipe important to take 1 tablets after welding, be sure to do the back protection, otherwise, it will lead to high temperature oxidation, back to the oxidation layer through the welding defects, welding slag grinding back with the same, so protect later can effectively prevent the oxidation of the back.
To improve the purity of argon to pure argon, see from the surface of the stainless steel, pure argon argon welding to brightness than the obvious light
You can do smear back protection agent in the back, is a can save argon, with 1 mm thickness can, when welding on the front and on the back, forming a layer of thin film forming a protective layer.
