Description

Technical Field

[0001] The invention relates to the field of standard section processing equipment, and in particular to automatic welding equipment for standard sections in which support rods are cylindrical. Background Art

[0002] The current standard section forms a rectangular frame through multiple struts and connecting rods. Rotary welding tooling is generally used to assemble the standard section. The current rotary welding tooling mainly clamps the struts on the rotary clamping tooling by clamping. The connecting rod is placed between the two struts, and the connecting rod is manually welded to the struts to connect and fix the struts.
