　　Thebutt welds joining together after forming the head, should be 100% rays or ultrasonic testing, the qualified level with the equipment shell.Finally forming the same welding seam detection level, scale and equipment shell, high waste.

　　Example: if the shell is 20% testing equipment, qualified III.The straight stitching and final weld, III qualify, welded joint coefficient is 0.85;

　　If the equipment shell is 100% inspection, II qualification.The straight stitching and final weld is unqualified, II welding joint coefficient is 1

　　So straight stitching, although 100% inspection, qualified level, along with the housing.

　　But must pay attention to the process manufacturing process:

　　The correct way is: blanking (line) - small plate together into a big board - molding - nondestructive testing

　　If it's wrong to do testing before molding, can't guarantee is qualified after forming.That is nondestructive testing refers to the nondestructive testing.(China Stainless Steel End Cap manufacturers)
