Abstract

The invention discloses an environment-friendly welding method for an iron block electroplated workpiece on a construction machine. The environment-friendly welding method is characterized by comprising the following steps that (1) at first, an iron block needing to be welded is fixed with a fixture; (2) the surface of an iron block base material is machined, and the roughness Ra of the iron surface after machining is 0.1-0.8 micron; (3) a welding head is heated, and the heating temperature is 1200-1400 DEG C; (4) a weldment heated in the third step is cleaned with organic cleaning solvents; (5) the iron block is then placed in the position where welding is required, and the welding head is utilized to make contact with the iron block to make the iron block and the machine be connected together; (6) burrs formed at the edge of the part are removed; and (7) inspection is carried out. The purpose of the method is to weld the iron block on the construction machine, the iron block part canbe welded conveniently and quickly, and the method has the advantages that the welding strength is good, the effect is stable, and the damage to the part is small.

Description

technical field [0001] The invention relates to an environment-friendly welding method for electroplated workpieces of engineering machinery iron blocks, and belongs to the technical field of welding. Background technique [0002] There are many welding methods on construction machinery, which can generally be divided into thermal welding, friction welding and electromagnetic welding.
