Things to Note When Welding Helical Weld Pipes

 

 

●Make sure the welding surface is clean, which is crucial to ensuring welding quality. Before welding, grease, dust and other substances on the surface of the steel pipe must be fully removed to ensure that the two welds are bonded.


●Control the welding temperature to avoid too high or too low temperature. Generally speaking, the welding temperature should be controlled between 800°C and 1100°C to ensure the quality and strength of the weld.


●Design a reasonable welding process. Because helical weld pipes are usually relatively large, durable welding joints are required. Therefore, engineers must develop welding processes that comply with specifications for specific situations.


●Establish a complete quality control mechanism. According to different welding quality and standards, corresponding inspection measures should be set up to ensure the quality and durability of helical weld pipe welding.
