Consistent layer welding technology

Using SMAW or GTAW welding methods, the welding parameters are the same for all layers, the first layer is welded to obtain a sufficient thickness of the weld layer, and the subsequent thermal cycle of welding causes the first HAZ in the weld bead form to be below the Ac1 temperature for heat affected zone Tempering, the heat affected zone to obtain a small amount of bainite tempered martensite mixed tissue, so as to obtain better toughness.
