API 1104 Welding Procedure Specification
Good morning, I am not new to writing welding procedures but I am new to the API 1104 code. My question is about 5.4.2.2 Base Material grouping. We are going to be welding API 5L Grade X42 to API 5L Grade X70. If I use Grade X70 for all my test does that cover all other grade lower than that...- Roadhogary
