Embodiment 1

[0027] Such as figure 1 with image 3 As shown, the present embodiment provides a double-sided welding method for arc T-shaped fillet joints of arc workpieces with closed structure, including the following steps:

[0028] Firstly, the arc workpiece 3 to be welded is fixed by the fixture, and the fixture and the laser beam produce relative movement along the direction of the welding seam. Among them, such as image 3 As shown, the tooling fixture is a pneumatic claw-type fixture, including a base 1 with a concave groove structure and two rotating pneumatic jaws 2, and the two rotating pneumatic jaws 2 are symmetrically arranged on the base 1 respectively. 1 on both sides of the wall, such as figure 1 The two ends of the circular arc workpiece 3 of the closed structure shown are respectively installed in the two said rotary pneumatic jaws 2, and the circular arc workpiece 3 is clamped by rotating the pneumatic jaws 2, while the rotary pneumatic jaws 2 can drive The arc workp...

Embodiment 2

[0034] Such as figure 2 with Figure 4 As shown, the present embodiment provides a double-sided welding method for arc T-shaped fillet joints of arc workpieces with segmented structure, including the following steps:

[0035] Firstly, the arc workpiece 3 to be welded is fixed by the fixture, and the fixture can drive the arc workpiece 3 to move along the welding seam track. And for such as figure 2 The arc workpiece 3 with segmented structure shown in the present embodiment, the tooling fixture is a profiled surface clamping and positioning fixture, including a concave groove structure of the machine base 2 9, two mobile tooling supports 10 and setting The profiling support 11 plate and the clamp 12 on the mobile tooling support 10, the two side walls of the said machine base 9 are provided with long guide rails, and the two said mobile tooling supports 10 are respectively symmetrically slidably connected to the said machine base two 9, the profiling pallet 11 is located ...

Abstract

The invention provides a circular-arc-T-shaped angle joint double-sided welding method. The method comprises the following steps that 1), a circular arc workpiece is fixed; 2), a welding head is arranged on each of the two sides of a welding seam, the position of each welding head is adjusted by an x\y\z axis adjusting mechanism and angle rotating adjusting mechanisms, and track detecting mechanisms electrically connected with a closed ring control system are arranged on the two sides of the welding seam; 3), the welding seam information is detected and transmitted to the closed loop control system, and the closed loop control system adjusts the positions of the welding heads according to the difference between the welding seam information and the theoretical information; and 4), after thepositions of the welding heads are adjusted, the circular arc workpiece moves along the welding seam track, and the two welding heads carry out welding processing on both sides of the welding seam. According to the circular-arc-T-shaped angle joint double-sided welding method, automatic welding is carried out on the two sides of the circular arc workpiece welding seam by the double welding heads,meanwhile the positions of the welding heads are adjusted automatically by simultaneously detecting the position of the welding seam in real time and feeding the position of the welding seam back tothe closed loop control system, so that automatic detection and positioning processing of the circular arc welding seam are realized without manual intervention, and the welding precision requirementof the circular arc welding seam can be met.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to a double-sided welding method for arc T-shaped fillet joints. Background technique [0002] For double-sided welds, there are many studies in the prior art. At this stage, it is mainly used for thick plate tailor welding double-sided welding and straight T-shaped fillet welds, using arc welding or laser welding. However, for the arc-shaped T-shaped fillet joint double-sided welds, the relevant content cannot be found in the existing open technology. The arc-shaped T-shaped fillet joint double-sided welds mainly refer to arc welds, including regular arcs or irregular arcs. Regular arcs, arcs include closed loop arcs or open arc segments, usually the arc tracks on both sides are the same, or different, but must be closed or disconnected at the same time, and the existing straight T-shaped fillet welds or The method and device of double-piece tailor welding of thi...
