"The Weld Crystallized!"

by Paul Ipolito
(Rochester NY)

Dear Elia- regarding the "cut pie" welder's concern regarding weld "crystallization"- I wish I had a dollar for everytime a well-meaning welder has told me about a weld crystallizing. I would have retired years ago. It bothers me that the misnomer has endured for so many years and it is a sign to me that the welder has not had even rudimentary instruction in welding metallurgy. Of course, you do not need to be a Materials Scientist to be a good welder, but shouldn't the most basic facts about the metals one is working on be known ? Yes, this is a minor detail, but to me it shows that we as an industry do not train and prepare welders correctly. I hope this opens some good discussion amongst your readership.

I agree with Paul.
The industry simply does not adequately train welders to ensure quality being built into the process. In a worse case scenario that i am unfortunately aware of (in an ASME certified facility) welders were not provided with basic tools (weld gauges, temp sticks,etc)or basic process parameters & were constantly saddled with drawing revisions, while being flogged to adhere to schedule through continuous overtime. The result was an almost 30% process re-work, poor material traceability & supply of deficient quality documents months after the job completion.
The additional production expense was simply treated like an unavoidable financial black hole.
