Welding equipment and combined welding method for combined welding

Abstract

The invention provides a welding device and a combined welding method for combined welding. The welding equipment includes the bed of the machine tool and the working platform for placing the base metal. The working platform is set on the bed of the machine tool. A part positioning component and a pressing component for pressing the positioned part on the base material. The combined welding method includes the following steps: positioning the base metal on the working platform; placing the working platform on the welding station for positioning, placing multiple parts on the base metal, and positioning the multiple parts through the positioning splint of the part positioning assembly. The two ends of the part are clamped and positioned at the same time; the base metal and the sub-pieces are pressed by the compression component; the base metal and the sub-pieces are welded to multiple sub-pieces; The assembly weldment formed by the base metal and sub-components described below. The invention has the advantages of improving the positioning reliability of parts and welding quality.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to welding equipment and a combined welding method for combined welding. Background technique [0002] In the field of combined welding technology, the welding equipment is used to combine the base metal and the sub-pieces set on the base material. If there are movement and positioning errors of the parts, generally the lead wire is artificially marked on the base metal first, and the sub-piece placement area is divided, and then the sub-pieces are placed in this area for welding. During the welding process, this method cannot guarantee the accuracy of the base metal. The position relative to the sub-parts is relatively fixed, and positioning errors are likely to occur, resulting in welding deviation; at the same time, due to the inconsistency of the pressing force between the base metal and the sub-parts during welding, it is easy to cause the welding to be too tight or too loose,...

[0002] In the field of combined welding technology, the welding equipment is used to combine the base metal and the sub-pieces set on the base material.

During the welding process, this method cannot guarantee the accuracy of the base metal. The position relative to the sub-parts is relatively fixed, and positioning errors are likely to occur, resulting in welding deviation; at the same time, due to the inconsistency of the pressing force between the base metal and the sub-parts during welding, it is easy to cause the welding to be too tight or too loose, causing welding deformation, and it is also easy to produce Partial deviation affects the welding quality, and the operation is difficult during the welding process, which is easy to cause safety hazards

In addition, the sub-part placement area is marked on the base metal, and the efficiency of welding one by one is low
