Embodiment Construction

[0027] A kind of HG785D steel plate robot single-sided welding double-sided forming method of the present invention, operates according to the following steps,

[0028] The first step: choose welding equipment;

[0029] Choose a robot, welding power source and positioner with matching power;

[0030] Step 2: Select the size of the groove form;

[0031] Select a butt joint with thickness M;

[0032] The third step: analyze and determine the welding process parameters;

[0033] Pulse welding with small welding deformation is used for welding. According to the forming condition of the back of the weld, the corresponding welding process parameters that cannot be welded on one side and formed on both sides are eliminated, and the three factors of welding current, welding speed and butt joint gap are selected, and the orthogonal test is passed. Design and determine the best parameter combination of the three;

[0034] Step 4: Check the docking gap;

[0035] Check whether the bu...

Abstract

The invention discloses a method for single-side welding double-side forming of an HG785D steel plate robot, belongs to the technical field of welding a load-carrying truck chassis, a crane lifting arm and multiple sorts of high-strength spandrel girders. The invention solves the technical problem by providing the method for single-side welding double-side forming of the HG785D steel plate robot, which aims to improve the welding seam forming quality of a product, therefore the welding percent of pass is increased, the worker labor intensity is reduced, and the advanced manufacturing level of an enterprise is improved. The invention adopts the technical scheme that the keys for realizing single-side welding double-side forming and the actual operation are firstly taken into consideration, the influences of welding current, welding speed and butt joint gap on welding quality are analyzed, and the problem that the welding percent of pass of single-side welding double-side forming is low is solved by adopting methods of determining the welding current, the welding speed and the joining gap, and the like. The method for single-side welding double-side forming of the HG785D steel plate robot provided by the invention can be widely applied to the field of single-side welding double-side forming.

Description

technical field [0001] The invention relates to a single-side welding and double-side forming method for HG785D steel plate robots, which belongs to the technical field of welding of truck chassis, lifting arms of cranes and various high-strength load-bearing beams. Background technique [0002] HG785D steel plate is a high-strength low-alloy steel plate for welded structures independently developed in China. This material has superior mechanical properties, many varieties and specifications, and excellent welding performance. It is suitable for use in high-strength welded structural parts. Lifting arms and various high-strength load-bearing beams and other high-strength load-bearing parts. The commonly used welding methods are electrode arc welding and manual gas shielded welding. [0003] Traditionally, based on the limitations of technology and equipment, for welds that require penetration in the structure, in order to ensure the welding quality, the method of double-sid...
