Abstract: Studied in the article is the contact-welding process for the Φ508 mm×17.5 mm HFW pipe.The performance of the weld of the said HFW pipe is tested.And the scratch mark on the pipe surface as caused by the HFW electrode tips is investigated.The testing result indicates that thanks to the HF contact welding, all the performance indexes of the weld of the said pipe are in compliance with relevant requirements as specified in GB/T 9711—2017 PSL2, which means that it is practical to adopt the said HF contact-welding process to produce excellent HFW pipes.The scratch marks as made by the electrode tips on the pipe surface will not produce any negative influence on the pipe performance.Moreover given relevant conditions are the same, the power consumption by the HF contact-welding process is just 55%of that by the HF induction welding process.
