The invention discloses a
welding process for aluminum profile
processing. The
welding process for the aluminum profile
processing comprises the following steps of preparing a base material, namely, preparing two aluminum profiles with the diameters of fifteen to thirty millimeters, and adding a
silicon material when the aluminum profiles are produced;
grinding the positions to be welded, namely,
grinding and brushing the surfaces to be ground of the aluminum profiles by using stainless steel wires until the aluminum profiles present metallic luster; removing
oxide films from the surfaces of the aluminum profiles, namely, treating the surfaces of the aluminum profiles by a chemical method, and removing the
oxide films from the surfaces of the aluminum profiles; preheating before
welding, namely, preheating the welded positions of the aluminum profiles by using an hot-
air blower; and welding by
argon arc welding, adopting a
tungsten electrode material in
argon arc welding, adding 1.5 to2.6 percent of
cerium oxide to pure
tungsten, and welding and simultaneously blowing the welded surfaces by using a
heat gun. According to the
welding process for the aluminum profile
processing, first, the welded surfaces of the aluminum profiles are ground and brushed by using the stainless steel wires, and then, the ground and brushed aluminum profiles are subjected to
secondary treatment by the chemical method, so that the oxide films on the welded surfaces can be removed effectively, which ensures the strength during welding, and is beneficial to welding.
