Embodiment Construction

[0016] A kind of aluminum alloy door and window group corner (including the welding process of "T" type connection), firstly install the group corner cushion block in the joint cavity of the aluminum alloy profile group corner, and then carry out argon arc welding treatment on the joint surface, and then The surface of the welded joint surface is repaired and sanded, and finally the surface of the aluminum alloy profile is colored.

[0017] Pre-treatment includes pre-welding preparation (check the placement of the welding machine, whether the electricity and argon gas are connected as required), water washing (use brush or sandpaper to clean the surface water, oil, oxides, etc. The spacer is installed in the cavity of the profile and the profile is placed on the special clamping table, the corners are butted, and the clamp is positioned and pressed).

[0018] The argon arc welding process: positioning the profiles clamped on the workbench by spot welding. The spot welding pos...

Abstract

The invention relates to a welding technology of aluminium alloy doors and windows. The welding technology comprises the following steps: a) water washing: using a brush or abrasive paper to remove water, oil and oxides on surfaces of sectional materials; b) clamping: mounting angle combining cushion blocks into cavities of the sectional materials and placing the sectional materials on a dedicated clamping workbench, butting to angle parts, and using a fixture to position and tightly press the angle parts; c) carrying out argon arc welding: using a spot welding method to position the sectional materials clamped on the workbench; starting welding from angle part ends on outer side and ending with angle part ends on inner side, and meanwhile, moving continuously and uniformly during welding; d) processing welding seams and repairing mold through sanding: using an angle grinder to repair crator smoothly firstly, using a thin flat file to finish outer sides of the angle parts, and polishing by using a flat plate sander; e) carrying out coloration treatment: carrying out coloration treatment to surfaces of aluminium alloy sections. The welding technology of aluminium alloy doors and windows has the advantages that problems of fit clearance of cavities of sectional materials and strength at positions of combining angles butt joint to are solved, surfaces of combining angles butt joint are processed without a trace, and market requirements are met.

Description

technical field [0001] The invention relates to a welding process of doors and windows of buildings, in particular to a welding process of aluminum alloy doors and windows. technical background [0002] At present, the angle assembly method of aluminum alloy profiles is usually connected by 45° aluminum angle code assembly angle and 90° self-tapping screw. The butt joints of the window corners made by the above two methods have the following disadvantages: 1. When the thickness of the profile cavity is too large or too small when the 45° aluminum corner code is assembled, it is impossible to ensure that the blanking thickness of the aluminum corner code is consistent with the profile cavity Body fit clearance. 2. The 90° self-tapping screw connection is not firm enough, and the strength and sealing of the corner cannot be guaranteed. 3. If the above two methods are not handled properly, there will be obvious butt wiring traces at the butt joints of the group corners, which...
