Factors Affecting the Quality of Welded Steel Pipe

Many factors affecting the quality of welded steel pipe, basically has the following several aspects:

(1) tube billet quality, chemical composition, mechanical properties, size deviation is the internal factors affecting the quality, appearance, etc.

(2) the welding process parameters: only by high frequency welding method, welding power, welding speed, temperature, the frequency of high frequency, extrusion pressure, impedance matching, the control of the triangle, etc all can affect the quality of welding.
