Embodiment 1

[0028] Embodiment 1, a method for improving the quality of plasma welding joints and welding efficiency, comprising the following steps:

[0029] 1) Clean the surface of the steel plate to be welded. The hot-rolled pickled steel SPHC steel plate for air-conditioning compressors with a thickness of 3.2mm is processed into small plates according to the size of the shell, and the burrs and oil stains at the cuts are removed;

[0030] 2) Prepare the shell blank of the air conditioner compressor, and use the rolling device to roll the small plate to form a compressor shell blank. The opening of the shell blank is 5-7 mm, and the shell blank enters the welding station for butt joint. Use fixtures to respectively fix the two sides of the butt joint of the air conditioner compressor shell blank, so that the steel plate does not slide during the welding process, the butt joint gap is 0, and the thickness direction of the steel plate on both sides of the butt joint is less than or equal ...

Abstract

The invention discloses a method used for efficiently welding straight seams of an air conditioner compressor shell. The technical problems that when straight seams of an existing air conditioner compressor shell blank are welded, welding quality is poor, and welding efficiency is low are mainly solved. The method used for efficiently welding the straight seams of the air conditioner compressor shell comprises the steps that (1) the to-be-welded surface of a steel plate is cleaned; (2) an air conditioner compressor shell blank is prepared; and (3) the air conditioner compressor shell blank iswelded, a small hole type plasma welding process is adopted, the butt joint straight seams of the rolled steel plate are welded, a plasma welding process is adopted, in the welding process, the shellblank is controlled to move along the center of a welding seam to achieve welding, the welding current is 200-240 A, the arc voltage is 25-31 V, and the welding speed is 750-850 mm / min. The method ishigh in welding efficiency, good in welding quality, easy and convenient to operate and low in welding cost.

Description

technical field [0001] The invention relates to a welding processing method for a compressor casing, in particular to a method for high-efficiency straight seam welding of an air-conditioning compressor casing, and belongs to the technical field of welding processing of iron and steel materials. Background technique [0002] Air-conditioning compressor shells often use hot-rolled pickled steel plates as substrates, and the thickness of the steel plates is 3.0-4.0mm. A compressor shell manufacturer mainly uses pickled steel plates with Baosteel brand SPHC to process compressor shell blanks. The C content of SPHC is 0.04-0.058%, and the yield strength is 232-336MPa. The steel plate is processed into a small plate according to the set size, and the small plate is rolled into a compressor shell blank by a rolling device, and then the plasma direct seam butt welding is performed. , and then continue to complete the assembly process of the subsequent air-conditioning compressor. ...
