specific Embodiment approach 1

[0025] Specific embodiment one: the present embodiment is a point ring laser and arc composite welding method, which is carried out in accordance with the following steps:

[0026] First, welding before welding bevel processing and tooling fixing:

[0027] The groove is processed at the surface to be welded at the surface to be welded, and the welded surface and groove are sanded and cleaned after processing, and finally the welded surfaces of the two workpieces to be welded are closely matched and fixed;

[0028] Second, point ring laser and arc composite welding:

[0029] The laser processing head is fixed with the welding torch, and the laser is controlled to emit a point ring composite beam transmitted to the laser processing head, and the arc is arced, and the point ring laser arc composite welding is carried out under the condition of welding speed of 0.5m / min ~ 2m / min, that is, the point ring laser and arc composite welding method is completed;

[0030]The dot ring composit...

Welding groove processing and tooling fixation before welding; 2. Point ring laser and arc hybrid welding. The invention is used for point ring laser and arc hybrid welding.

Description

Technical field [0001] The present invention belongs to the field of laser processing technology. Background [0002] In recent decades, the scope of application of laser welding technology has been expanding. Laser welding technology has been widely used in defense, shipbuilding, aerospace and medical industries. With the continuous improvement of the laser system, the laser power continues to increase, the beam quality continues to increase, and laser welding can achieve rapid welding with large melt depth and high energy density. At the same time, the laser welding heat affected zone is small, the joint quality is good, and it is easy to realize automation, which has become one of the important technical means in the manufacturing field. [0003] Due to the small size of the laser beam spot, the assembly accuracy of the weldment is higher and the assembly process is more complicated. In addition, highly reflective materials such as aluminum alloys make the absorption rate of l...
