Automatic nozzle and submerged arc welding machine and control system

Abstract

The invention provides an automatic nozzle and submerged arc welding machine and a control system. One side of a horizontal movement unit is connected with a self-aligning mechanism, the other side ofthe horizontal movement unit is connected with a rotating support, a rotating system is installed on the lower part of the rotating support, a drag chain accessory is connected with the lower part ofthe rotating system, a welding wire disc, a mounting bracket of the welding wire disc and a remote operation control box are fixed on a bracket of the drag chain accessory, the front end of the dragchain accessory is connected with a perpendicular movement unit, and a wire feeding unit is installed at the lower end of the perpendicular movement unit. According to the automatic nozzle and submerged arc welding machine, the digitalization degree is improved, the operation difficulty is reduced, the self technical level requirements of a welder are reduced, the welding preparation time is shortened, the product manufacturing cycle is increased, the influence of human factors on the welding process is reduced, and the welding quality is ensured.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a submerged arc automatic welding machine and a control system. Background technique [0002] Most of the current submerged arc welding of chemical container cylinders and nozzles uses semi-mechanized welding equipment, which has low automation, difficult operation, poor welding quality, low efficiency, and long preparation time before welding. [0003] The submerged arc automatic welding machine is a welding machine that uses the arc to burn under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke and dust make it the main welding special device in the production of pressure vessels, pipe section manufacturing, and box-type beam-column steel structures. [0004] The pipe submerged arc automatic welding machine is mainly used as a special equipment for the submerged arc automatic welding ...
