Description

[0002] The steel structural member submerged arc welding machine with a top protection structure is a device for welding steel structures, mainly used for welding steel structural members with a top protection structure. The submerged arc welding machine is a method of welding by burning an electric arc under a layer of flux. During the welding process, the electric arc burns under the flux layer, melting the welding wire and the metal on the surface of the welding piece to form a weld.

[0003] When the submerged arc welding machine welds steel structural members with a top protection structure, the two steel structures to be welded are first spliced together. The submerged arc welding machine is placed on the spliced steel structure, the welding wire is in contact with the welding piece, the welding power source is started, and an electric arc is generated between the welding wire and the welding piece. However, since the submerged arc welding machine is moving during welding, and the submerged arc welding machine generates some vibrations during operation, the submerged arc welding machine moving on the steel structure will also vibrate during movement. At this time, the vibration of the submerged arc welding machine itself during operation and the vibration during moving welding will cause the two steel plates to vibrate. At this time, the spliced steel plates will crack or displace, resulting in uneven width and height of the weld, and the weld will also have defects such as porosity, slag inclusion, incomplete fusion, and cracks, affecting the overall appearance quality of the steel structure.
