Weld Seam Appearance: The weld seam should be flat, smooth, and free from defects such as cracks, pores, and others. These defects can severely impact the strength and sealability of the pipeline.
Weld Seam Inspection: Non-destructive testing methods such as radiographic inspection and ultrasonic inspection are employed to examine the quality of the weld seam, ensuring that there are no internal defects or damages within the weld.
Welding Equipment and Materials: Reliable welding equipment and materials with proven performance are selected to ensure the stability and reliability of the welding process.
