The code and procedure will be determined by what type of job the welder is being certified for. There are structural welding tests, pipe welding tests, aerospace welding tests, food service welding tests and more.
The welder must have a copy of the WPS that they will be certified on, the (PQR) and be dressed in PPE for welding. WJMG can provide the welding machines and coupons or the welder can bring their own.
