Keyhole technique of dabbing on puddle ! One of the ways to TIG welding the pipe root !

Hello everyone. Also called “root pass“ or “back bead weld“. There are many ways to weld the roots of pipes. Among them, the keyhole technique is a good welding method. The keyhole technique is also broken down in several ways. Today, I will introduce one of them. This is a method of opening the keyhole by repeatedly inserting and removing the welding rod into the molten pool. In the future, we will introduce other keyhole methods one by one. Thanks for watching and have a nice week. #pipe #Root #TIG #welding #stainless #tube #HAGOJIBI
