Defect Elimination

Austenite stainless steel weld overlay cladding is widely used for the equipments working in pressurized hydrogen environment such as hydrogenation reactors. Surface cracking is a basic failure mode of the weld overlay cladding, and also a quite difficult problem for safety assessment and defect elimination. In this paper, two cases of surface cracking of austenite stainless steel weld overlay cladding are introduced. Firstly, the inspection results and cracking causes are analyzed in detail. Secondly, two kinds of treatment methods for the defects are introduced. Finally, some suggestions for inspection and assessment of surface cracking of weld overlay cladding are proposed.
