Embodiment 1

[0017] The present invention provides a tree-shaped special swing welding method. When gas-shielded arc welding is performed, the measurement position formed by the base metal and the base metal overlaps the solid lining material on the inner side. The specific operation method is as follows:

[0018] Call the preset detection sensor to detect welding position information; establish a spatial rectangular coordinate system according to the position information, and calculate the coordinates of each welding point on the position according to the preset step width of the welding torch; according to the calculated coordinates of each welding point , generating a swing path corresponding to the welding gun, and controlling the welding gun to perform welding along the swing path. The calculation method of the swing path is as follows: first teach the starting point Pstart, the end point Pend, the step size w_length, and the swing width w_width of the required welding position on the ...

Embodiment 2

[0020] Divide the welding seam into several sub-welding seams, use the length of the sub-welding seams as the step width of the welding torch, and calculate the coordinates of each welding point on the measurement position plane on both sides of the measurement position.

[0021] In this embodiment, the above-mentioned welding seam can be divided into several sub-welding seams, and the length of the sub-welding seam can be used as the step width of the welding torch, and the coordinates of each welding point on the measurement position plane on both sides of the above-mentioned measurement position can be calculated. According to the calculated coordinates of each welding point, a swing path corresponding to the welding torch is generated, and the welding gun is controlled to perform welding along the swing path.

[0022] In the embodiment, after calculating the coordinates of each welding point on the measurement position surface on both sides of the above-mentioned measuremen...

Embodiment 3

[0025] First, teach the start point Pstart, end point Pend, step length w_length, and swing width w_width of the required welding part on the robot, and then calculate the path by remembering the start point, end point, swing width, and step length, and calculate the step length coordinate Sp. When calculating Define three coordinates as P_A, P_B, and P_C, and finally calculate P_A, P_B, and P_C in the loop statement and perform welding according to the coordinates of the calculation results.

Abstract

The invention provides a tree-shaped special swing welding method. When gas shielded arc welding is carried out, a solid substrate is overlapped on the inner side of a base material with regard to thebase material and a measurement position formed by the base material. The specific operation method is as follows: a preset detection sensor is called to detect information of a position needing to be welded; a space rectangular coordinate system is established according to the position information, and coordinates of each welding point on the position are calculated according to the preset stepping width of a welding gun; and a swing path corresponding to the welding gun is generated according to the calculated coordinates of each welding point, and the welding gun is controlled to perform welding along the swing path. The tree-shaped special swing welding method is mainly used for welding path repeated calculation and assignment welding and realizing special swinging mode welding. The tree-shaped special swing welding method can be used for quickly welding plane weld seams and meet requirements of customers for quick welding of long weld seams. Major technical problems comprise swing methods and processes of unique welding.

Description

technical field [0001] The invention relates to the welding field, in particular to a tree-shaped special swing welding method. Background technique [0002] Welding is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. It is widely used in the fields of construction engineering and steel structure components. [0003] Among them, welding efficiency and welding quality directly affect the efficiency and quality of construction and steel structure components. Therefore, in order to improve welding efficiency and welding quality, welding robot automation technology is gradually replacing manual welding. However, since the welding process of welding robots is a relatively complex mechanical, control, and metallurgical forming process, the flexibility is not as good as that of humans. Nowadays, welding robots also have many methods for planes, but they are generally welded bas...
