Abstract
Disclosed is an aluminum alloy thick plate welding process. The process includes machining a weld groove firstly, with the inclined angle ranging from 60 DEG to 80 DEG, washing the surface of the plate with acid after alkali, soaking the plate in a sodium hydroxide solution with the mass ratio ranging from 5% to 8% at temperature of 20 to 50 DEG C for 1 to 3 minutes, washing the plate with water, soaking the plate in a hydrochloric acid with the mass ratio of 15% at temperature of 20 to 50 DEG C for 1 to 3 minutes, performing neutralizing treatment, washing with water, and drying; allowing the pre-welding fitting gap to be 20% of the thickness of the plate, adopting alternating-current argon tungsten-arc welding, and adopting pure aluminum wires, welding current ranging from 220 to 240 A and filler wires with diameters thinner than 30% of the plate. The process has the advantages that operation is simple; under the conditions that process parameters are controlled stably, welding effect is good, and the problems of oxidation, porosity, thermal cracking and subsidence are avoided.
