Presented At: 
CWA Conference 2014

As the number of applications utilizing high strength steels increases, so does interest in controlling the hydrogen level of welds produced during the fabrication of these materials. Consumables designed for high productivity welding must be carefully selected and used in order to meet the restricted hydrogen requirements of these challenging base metals.
