Influencing Factors Of Weld Cracking Of High-Frequency Jan 29, 2021 · In high-frequency welded pipes, the manifestations of cracks include long cracks, partial periodic cracks, and irregular intermittent cracks. Some stainless steel welded pipes have no cracks on the surface after welding, but after flattening, straightening or water pressure tests, cracks appear.
The high frequency tube welding involves the application of a high current in the range 100 - 500 kHz, with the tube forming and energy performed by separate units. This welding method simultaneously utilizes pr in order to join the strip edges of the open metal.
