Welded Seam Inspection: Non-destructive testing methods such as radiographic inspection and ultrasonic inspection are employed to examine the quality of the welded seam, ensuring that there are no internal defects or damages.
Welding Equipment and Materials: Reliable welding equipment and materials with proven performance and quality are selected to ensure the stability and reliability of the welding process.
