Description

Technical Field

[0001] This utility model relates to the technical field of submerged arc welding machines for steel structures, specifically, to a mobile submerged arc welding machine for steel structures. Background Technology

[0002] Arc welding machines are welding machines that use an electric arc burning under a layer of flux to perform welding. Their inherent advantages, such as stable welding quality, high welding productivity, no arc light, and very little smoke and dust, make them the main welding machines used in the fabrication of pressure vessels, pipe sections, and box-type beam and column steel structures.

[0003] Patent application number 202020890502.7 discloses a gantry submerged arc welding machine for steel structure production, including a base and a lifting plate. A storage box and a welding head are fixedly installed at the top and bottom of the lifting plate, respectively. A feed pipe and a discharge box are fixedly sleeved at the top and bottom of the storage box, respectively, and a discharge pipe is fixedly sleeved at the bottom of the discharge box. This gantry submerged arc welding machine for steel structure production uses a motor to drive the rotation of a rotating shaft. Seven rotating plates evenly distributed on the shaft transport the flux from the storage box to the discharge pipe, where it falls to the area requiring welding.

[0004] Although the flux can be automatically delivered during arc welding, the steel structure is prone to shaking and misalignment due to external factors such as the arc welding machine and the addition of flux during the welding process. Moreover, it is inconvenient to move, resulting in poor stability of the raw materials during the welding process and poor welding effect. Utility Model Content
