Technical Field

[0001] This utility model relates to the field of welding head mounting structure, and in particular to an adjustable auxiliary positioning welding head mounting structure for welding. Background Technology

[0002] The crane beam is a key component used to support and suspend cranes. It is typically made of steel plates, possessing high strength and corrosion resistance, and capable of withstanding large loads and shear forces. During production, the crane beam requires welding of its components using gantry welding equipment. However, existing gantry welding equipment features a fixed welding head structure, with the welding torch directly mounted on the welding head structure. This presents the following problems when welding the steel plates of the crane beam:

[0003] 1. The existing fixed welding head structure cannot adjust the position and angle of the welding torch head, which has defects in actual use and cannot guarantee the welding multi-position requirements.

[0004] 2. The existing fixed welding head structure cannot position the steel plate to be welded when the welding torch head is driven to perform welding operations, which affects the welding quality. Utility Model Content
