Abstract
The utility model relates to a welding head structure for connecting aluminum alloy sections. The welding head structure is mainly used for section structures of side walls, floors and the like of aluminum alloy vehicle bodies of railway vehicles. The welding head structure comprises an aluminum alloy section A and an aluminum alloy section B which are subjected to butt welding, and the welding surfaces of the aluminum alloy section A and the aluminum alloy section B form an I-shaped groove. According to the welding head structure, the conventional arc welding process is replaced with a friction stir welding process, so that the welding head structure has the characteristics that the attractive appearance and excellent quality of the welding head are guaranteed; metal and protective gas are not needed to be filled during the friction stir welding, so that arc light and dense smoke are not generated, and the influence of temperature and humidity can be avoided; and the welding head structure is low in manufacturing cost and environment-friendly.
Description
Technical field
The utility model relates to a kind of plumb joint structure that aluminium alloy extrusions connects that is used for, and is mainly used in the profile structure such as side wall of aluminum alloy bodywork of rail vehicle, floor.
Background technology
Traditional arc-welding is adopted in the welding of aluminum alloy bodywork section bar, and joint design is only applicable to arc-welding.The aluminium section bar arc-welded joint is as shown in Figure 1, is provided with " V " shape groove 3 between A aluminium section bar 1 and the B aluminium section bar 2.Aluminium alloy arc-welding distortion is bigger, is prone to produce defective, and the joint moulding is not attractive in appearance.In the welding process, arc light, flue dust etc. pollute big, direct harmful to human, and the humiture of welding environment had strict demand.
Summary of the invention
The purpose of the utility model is, to the deficiency of prior art, a kind of plumb joint structure that aluminium alloy extrusions connects that is used for is provided, and can realize that friction stir welding substitutes traditional arc welding process, and process distortions is little, and intensity is high, pollutes few.
The technical scheme of the utility model does, a kind ofly is used for the plumb joint structure that aluminium alloy extrusions connects, and comprises butt-welded A aluminium section bar and B aluminium section bar, and the solder side of said A aluminium section bar and B aluminium section bar becomes " I " shape groove.
And A aluminium section bar and B aluminium section bar are through the friction stir welding welding.
The A aluminium section bar becomes " I " shape groove with the B aluminium section bar through solder side, makes A aluminium section bar and B aluminium section bar realize the friction stir welding welding.
The utility model adopts friction stir welding to substitute traditional arc welding process; Except that bringing shaping outward appearance attractive in appearance and outstanding joint quality; Because agitating friction is welded in the welding process and need fill metal, protective gas; Do not produce arc light, dense smoke, characteristics such as do not receive that humiture influences also have a clear superiority in manufacturing cost and environmental protection.
Description of drawings
The plumb joint structure that Fig. 1 connects for existing aluminium alloy extrusions.
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 2; A kind of plumb joint structure that is used for the aluminium alloy extrusions connection; Comprise butt-welded A aluminium section bar 1 and B aluminium section bar 2, the solder side of said A aluminium section bar 1 and B aluminium section bar 2 becomes " I " shape groove 4, and A aluminium section bar 1 welds through friction stir welding with B aluminium section bar 2.
Claims (1)
1. one kind is used for the plumb joint structure that aluminium alloy extrusions connects, and comprises butt-welded A aluminium section bar (1) and B aluminium section bar (2), it is characterized in that the solder side of said A aluminium section bar (1) and B aluminium section bar (2) becomes " I " shape groove (4).
