[0002] In order to reduce the weight of the product and improve the heat dissipation efficiency of the product, the annular radiator products are mostly thin-walled parts, and the product is welded by argon arc welding. The welding deformation has always been a difficult point in the production of the product, especially the surface air collector tube. The welding deformation at the nozzle is the most serious, and the deformation after welding often exceeds the control requirement of 5mm, and there is no experience in the control of argon arc welding with similar structures in my country for reference, and the welding deformation at the nozzle of the surface air collector has become a constraint Technical Difficulties in Delivering Ring Radiator Products

Embodiment Construction
[0035] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0036] Such as Figure 1~3 As shown, the nozzle of the air collector on the surface of the annular radiator needs to be welded. The welding position includes two parts, one part is the connection between the air collector 1 and the air bellows 4 ( figure 1 The middle light gray line contains two straight lines and one arc), and the other part is the connection between the transition ring 2 and the exhaust joint 3 ( figure 1 medium light gray circular line), where the wall thickness of the air collector 1 part is 0.6mm, the wall thickness of the transition ring 2 part is 1.2mm, the thickness of the exhaust joint 3 welding part is 1.2mm, and the wall thickness of the air bellows 4 part is 1.0mm, the welding method used is manual argon arc welding. The welding process includes the follow...

Abstract
The invention discloses a method for controlling argon arc welding deformation of a mouthpiece of an air collector on the surface of an annular heat radiator, and particularly relates to a method forcontrolling welding deformation generated in the welding process of a lap fillet weld joint of an air collector with the part thickness being 0.6 mm to 1.2 mm. The method comprises the steps that firstly, the air collector (1) and a transition ring (2) are welded well; then the air collector (1) is beaten to be in a drum type, that is, the outer surface of the air collector (1) bulges outwards, and the bulging amount is about 1.5 mm; the air collector (1) and an air corrugated pipe (4) are subjected to positioned welding, the transition ring (2) and an exhaust joint (3) are subjected to positioned welding, the length of positioned welding points is controlled to range from 3 mm to 7 mm, and the four positioning points of the transition ring (2) and the exhaust joint (3) are evenly distributed; and welding is carried out through a balanced welding manner and a subsection welding manner, and the outer surface welding deformation amount of the air collector (1) can be within the range of1 mm to 3 mm after welding is carried out.
