A welding method for automatic tracking and positioning of welding spot center of steel mesh sheet

Abstract

The invention provides an automatic tracking and positioning welding method for the welding spot center of steel mesh, which comprises the following steps: preset the reference point of the welding spot automatic tracking and positioning device on the welding girder; determine the welding range of the welding torch according to the reference point; according to the welding torch The scope determines the feeding parameters of the feeding platform; according to the feeding parameters, set the three-dimensional operation parameters between the automatic welding spot tracking and positioning device and the A and B steel bars to be welded; start the automatic welding spot tracking and positioning device, wire feeding device and welding torch, and run according to the three-dimensional operation Parameters Weld the welded A and B steel bars on the welded girder. In the process of three-dimensional or multi-layer steel mesh welding, due to the displacement of the longitudinal axis of the welded steel bar, the displacement of the transverse axis is greater than the diameter of the electrode and the welding cannot be performed, and the horizontal and vertical height error dimensions exceed the diameter of the electrode and cannot be welded. sex. It becomes possible to automate, scale and continuous normal manufacturing of single-layer and multi-layer steel mesh.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic tracking and positioning welding method for the welding spot center of a steel mesh sheet. Background technique [0002] At present, in the automatic welding process of all manufactured single-layer steel mesh sheets, the working trajectory of the welding machine is a horizontal and vertical horizontal linear motion with an accuracy of more than 7 grades, or a horizontal arc motion within 180 degrees. The center position of the melting point of the welded steel bar must be equal to the center of the working track of the welding machine. If the vertical, horizontal, and horizontal lines of the center of the welding melting point of the steel bar are offset by more than twice the diameter of the welding rod, the automatic welding machine will lose its welding function. [0003] Therefore, this process has extremely high requirements on the dimensional accuracy of the...

Problems solved by technology

[0003] Therefore, this process has extremely high requirements on the dimensional accuracy of the matching formwork of the welding machine and the welded steel bar. In the actual welding process, a large number of steel bars with deformation coefficients larger than the diameter of the welding rod cannot be welded. For this reason, this process has a single layer of steel bar Mesh cannot be continuously produced and the limitations of large-scale production

Not to mention the restriction that the three-dimensional welding of the steel bar square cage above the second floor can not be carried out
