Hi everyone,
I'm having some problems trying to control the discoloration of the Titanium Welds on tubing 1" Dia., I'm using TIG Process; and due to acceptance criteria from the AWS D17.1 any Blue Discoloration is rejected, I know that most of my problem is not enough gas purge and shielded. But, did anyone know a better way to purge and shielded the parts during the weld to avoid the Discoloration.
Thanks in advance for your help.
Carlos
