Document Type and Number:
WIPO Patent Application WO/2012/014932
Kind Code:
A1
Abstract:
Disclosed is a method for penetration welding of austenitic stainless steel. By using a welding rod with a high silicon content, said method can produce a weld with excellent penetration performance without using a back-shielding gas. In said method, either: TIG welding is performed using an austenitic stainless steel welding rod containing 0.65-1.50% silicon by weight; or TIG welding is performed using an austenitic stainless steel welding rod containing 0.65-1.50% silicon by weight, with the groove face coated with a solvent mixed with a flux that contains at least 60% silicon by weight.
