Hydrogen Embrittlement Testing for Aluminium

Hydrogen cracking, also called ‘delayed cracking’ is a challenge for the joining and performance of welded structures. This cracking takes different forms depending on the exact source of the hydrogen.

Hydrogen can cause a loss of ductility or a reduction of load-carrying ability as well as catastrophic brittle failure far below the usual yield or design strength. TWI has experience in helping prevent hydrogen assisted cracking in materials including aluminium and you can find out more here: Hydrogen Embrittlement Testing for Aluminium
