The so-called stainless steel welded pipe gap refers to the small weld that is not melted during the welding process of the pipe. 1. Welding temperature control of stainless steel welded pipes. The welding temperature is mainly affected by the high frequency eddy current thermal power. According to the relevant formula, the high-frequency eddy current thermal power is mainly affected by the current frequency, and the eddy current thermal power is proportional to the square of the current excitation power; the current excitation frequency is affected by the excitation voltage, current, capacitance and inductance. For low carbon steel, the welding temperature is controlled at 1250~1460℃, which can meet the welding requirements of the tube wall thickness of 3~5mm.
