Embodiment Construction

[0011] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0012] Such as figure 1 Shown, a kind of salt-bath brazing process of 6063 aluminum alloy, described brazing process steps are successively:

[0013] a) Preparation before welding: soak the base metal 6063 aluminum alloy and solder in 5% (mass fraction) sodium hydroxide solution at 60°C for 1-2 minutes to remove surface impurities and oil stains, then rinse with plenty of water, After drying, the workpiece is clamped with a fixture;

[0014] b) Heating: Put the salt bath tank with flux into the furnace protected by nitrogen to heat up to 560°C;

[0015] c) Heat preservation: put the pre-equipped parts into the salt bath for a certain period of time;

[0016] d) Cooling: take out the workpiece to cool;

[0017] e) Post-welding treatment: Rinse the workpiece in boiling water to remove residual flux on the surface of the workpiece, then put it in a pickling tan...

Abstract

The invention relates to brazing processes, particularly to a salt bath brazing process of a 6063 aluminum alloy. The process comprises the steps of pre-brazing preparation, heating, heat preservation, cooling and post-brazing treatment. The 6063 aluminum alloy brazed through the process has good mechanical performance and good physical performance. According to the salt bath brazing craft process of the 6063 aluminum alloy, the operation steps are simple, convenient and easy to master; constant temperature control is performed; heating is even and rapid; the quality of brazing seams is high; brazing of a large amount of brazing seams can be completed in one step, so that high production efficiency can be achieved. Therefore, the salt bath brazing craft process of the 6063 aluminum alloy is good in quality.

Description

technical field [0001] The invention relates to a brazing process, in particular to a salt bath brazing process of 6063 aluminum alloy. Background technique [0002] 6063 aluminum alloy is widely used in the frames of architectural aluminum doors, windows and curtain walls. It has high plasticity, high strength and excellent corrosion resistance, and is suitable for pressure processing. However, due to its low melting temperature, its brazing property is poor, which greatly limits the application of 6063 aluminum alloy. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a salt bath brazing process for 6063 aluminum alloys. Its temperature is controlled by a constant temperature, the heating is uniform and rapid, and the weld seam quality is high. The technical scheme adopted is as follows: [0004] A salt bath brazing process of 6063 aluminum alloy, the process steps are as follows: [0005] a) Preparation before weldi...
