Description
Technical Field
The invention relates to a robot welding technology of a hydraulic support structural member, in particular to a method for improving the deposition rate of the hydraulic support structural member welded by a robot.
Background
With the rapid development of advanced manufacturing and automation technology, robot welding has attracted attention and becomes an effective means for improving welding efficiency and quality, and the robot welding is widely popularized and applied in the fields of engineering machinery and automobile manufacturing. The hydraulic support main structural members such as a top beam, a shield beam and a base are typical box-shaped structural members, and the box-shaped structural member welding robot workstation mainly comprises an arc welding robot, a welding power supply, a welding gun wire feeding mechanism, a positioner, a tool clamp, a control system and the like. The welding robot workstation is suitable for welding various box type workpieces, and can realize automatic welding of various boxes by setting variety selection parameters in a control system and replacing different tools and clamps in the same workstation. In the robot welding process, different welding wire diameters adopt different parameters such as welding current, voltage and the like, different droplet transition forms and arc behaviors are shown, and meanwhile, the welding efficiency is greatly different. The filaments (diameter of welding wire is less than or equal to 1.2mm) are generally welded by short circuit transition. Its advantages are low voltage and current, and high welding speed. When welding thin plates, the productivity is high and the deformation is small.
In the hydraulic support structural part, the welding conditions of medium plates are more and more, and molten drops are generally welded in a fine particle transition mode when thick wire welding is applied. It features large current, high arc voltage and free falling molten drop in small size into molten pool. When fine particles are in transition, the electric arc penetrating power is strong, the base metal penetration depth is large, the welding effect is good, and meanwhile, the welding efficiency can be obviously improved by thick wire welding.
Therefore, the diameter of the welding wire is less than or equal to 1.2mm, and obviously, the requirements cannot be met, and currently, no relevant precedent exists for welding phi 1.4 and phi 1.6 welding wires for the robot welding of the hydraulic support structural member.
