Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to welding equipment and a welding method for circular steel material splicing. Background Art

[0002] When circular steel is spliced ​​and welded, a girth welding machine is generally used for welding. It is generally used for welding products such as hydraulic cylinders, automobile steering frames, drive shafts, gas cylinders, chemical and medical containers, liquefied gas tanks, fire-fighting equipment, rollers and liquid storage cylinders for mines and production lines.

[0003] When circular steels are spliced ​​and welded, the two ends of the two sets of circular steels are often aligned, the two sets of circular steels are rotated synchronously, and then the joints are welded. However, when welding two sets of circular steels in a vertical state, one end of one set of circular steels often needs to be stamped or cut so that it can fit with the outer surface of the other set of circular steels. Since the two sets of circular steels are in a vertical state, it is not easy to fix them or rotate them, which increases the difficulty of welding.
