Study of quality of welded joints of high-strength ferritic steel made with a cover of a mixture of argon and hydrogen

Year: 2025

Type: article

Abstract: Testing of joints made during welding with a TIG of high-strength, fine-grained ferritic steels confirms that a small addition of hydrogen to the argon-based shielding mixture does not affect the formation of hydrogen cracking.It is very important to strictly adhere to the technological regimes during steel preparation before and after welding.Then, the controlled addition of hydrogen coming from the casing mixture has a positive effect.Due to the presence of 2% hydrogen, the joints are characterized by deeper penetration, lower inclination to edge flooding and smooth face.They are technically correct and impeccable in terms of aesthetics.
