Abstract
The invention discloses a consumable-electrode argon arc welding process for an aluminum alloy and wear-resisting steel dissimilar metal. The consumable-electrode argon arc welding process comprises the following steps: cleaning the surfaces of the aluminum alloy and a wear-resisting steel parent material before welding, then, cleaning the surfaces with acetone, and drying the surfaces in air; pre-heating the parent material for 30-40 seconds at a pre-heating temperature of 120-140 DEG C before welding, roasting a welding rod for 1-2 hours at 300-400 DEG C before welding, and preserving the temperature of the welding rod for later use; surfacing a transition layer on a wear-resisting steel base body by adopting electric-arc welding, and polishing the surface of the transition layer subjected to surfacing after the surfacing is completed; welding and connecting a welding seam on the transition layer by adopting consumable-electrode arc welding, carrying out arc striking and arc drawing uniformly during welding; and after the welding is completed, continuously introducing argon gas until the transition layer is cooled, then, repeatedly grinding the transition layer by use of adhesive paper until welding slag on the surface of the welding part is removed. The welding process disclosed by the invention guarantees that the welding seam is free of cracks and the welding steam is high in strength, and cracking is prevented under heating and rolling states; and the process is simple and low in production cost.
