Description

Technical Field

[0001] The utility model belongs to the technical field of supporting structures, in particular to a supporting structure for beam welding. Background Art

[0002] Beam welding is a welding process that connects beams to other structural elements or parts. A beam is usually a structural element that spans horizontally or is supported on two fulcrums to support loads, transfer forces or provide structural support. Beam welding is a common task in structural engineering, and its quality and reliability are critical to the performance of the entire structure. Therefore, when welding beams, it is necessary to comprehensively consider factors such as material properties, welding process, structural design and safety.
