Embodiment

[0015] Cut and saw the self-cast ZL203 aluminum-copper alloy sample into a block with a length of 35mm, a width of 15mm, and a thickness of 15mm. After the oxide film on the surface is smooth and the surface is to be welded, soak it with acetone solution, clean it with an ultrasonic cleaner for 15 minutes, remove oil and other impurities, and then quickly dry it with a hair dryer. In order to ensure that the joints are evenly stressed, the aluminum-copper alloy is welded in the form of a butt joint.

[0016] Diffusion welding of ZL203 aluminum alloy in a resistance furnace under the protection of high-purity argon. After the diffusion welding material is ready, heat up the resistance furnace and keep the heating rate at about 25°C / min. 65 Cu 20 Al 5 Y 10 The alloy is sandwiched between the ZL203 aluminum alloy columnar materials, and then put into the resistance furnace, and the argon gas is passed through for about 2 minutes before putting in, to ensure that the air in th...

Abstract

The invention discloses a new method for welding a ZL203 aluminum alloy on a preset magnesium-based amorphous intermediate layer, and belongs to the field of welding of aluminum alloys. The method is characterized by comprising the following steps of: cutting and sawing a self-poured ZL203 aluminum copper alloy test sample to form a block with the length of 35mm, the width of 15mm and the thickness of 15mm; polishing a surface to the welded of the test sample, and removing an oxidation film on the surface; and in order to ensure stressing uniformity of a joint, welding an aluminum copper alloy in a butt joint mode. According to the optimal parameter of a diffusion welding process, the pressure is 0.5MPa, the temperature rise velocity is 25 DEG C / min, the welding temperature is 510 DEG C, and the heat preservation time is 20 minutes; and at the moment, the tensile strength of a ZL203 aluminum copper alloy joint reaches the maximum value 185MPa, and the strength of a ZL203 aluminum copper alloy body is 180 to 190MPa.

Description

technical field [0001] The invention relates to the field of aluminum alloy welding, in particular to a new method for welding a ZL203 aluminum alloy with a magnesium-based amorphous intermediate layer preset. Background technique [0002] Due to the low melting point of aluminum and aluminum alloy, which is very close to the melting temperature of brazing material, the temperature range available for brazing aluminum and aluminum alloy is very narrow, and the brazing process of aluminum and aluminum alloy is difficult to control. During the brazing process, if the temperature is not properly controlled, it is easy to cause the base metal to overburn or even melt. Some aluminum alloys strengthened by heat treatment will cause overaging or annealing and other softening phenomena due to brazing heating, resulting in deterioration of the mechanical properties of the brazed joint. reduce. Moreover, the corrosion resistance of aluminum and aluminum alloy brazing joints is easily...
