Abstract

The invention discloses a method for welding inconel through CMT submerged-arc welding. The method comprises the following steps that (1), a grinding piece is loaded by using an electric angle grinder to grind a workpiece so as to remove impurities and oxides on the surface of the workpiece; (2), welding equipment are configured, wherein the welding equipment comprise an ABB robot, a CMT welding machine power supply, a water tank, a CMT welding gun and an inconel submerged-arc welding flux; and (3), the welding process is carried out, the welding process parameters are set, the CMT welding gun is clamped by the ABB robot, a gun head extends into the submerged-arc welding flux for CMT submerged-arc welding, and slag removing operation is carried out between the welded layers. According to the method for welding inconel through CMT submerged-arc welding, the limitation that CMT gas shielded welding cannot be welded for a narrow-gap deep groove can be solved, full-automatic operation can be realized, and the method has the characteristics of good quality stability, environmental friendliness, energy conservation, high efficiency, high material utilization rate and the like.

Description

technical field [0001] The invention relates to the field of welding methods, in particular to a method for welding inconel by CMT submerged arc welding. Background technique [0002] Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method in which the arc burns under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacturing, and box-shaped beams and columns. In recent years, although many new welding methods with high efficiency and high quality have appeared successively, the application field of submerged arc welding has not been affected in any way. From the point of view of the weight share of deposited metal by various fusion welding methods, submerged arc welding accounts for about 10%, and it has not changed...
