The welding operation machine is used for flat welding,butt welding seam and internal and external longitudinal welding seam .

The welding operation machine, also column and boom,  is used for flat welding,butt welding seam and internal and external longitudinal welding seam of cylindrical body (like pipe, tank) and it can be fitted with roller stand for welding seam of internal and external circular welding seam.If it is fitted with positioner,different type of body can be made for different places of welding.

Main body box type welding structure is treated by stress after welding and fine maching shall be made.The guide surface adopts precision grinding processing or ensure the sophistication and smooth running.

The precision grinding rack is installed on crossbeam to guarantee its flexibleness and free expansion and contraction.

The crossbeam's expansion and contraction,motor-driven turning of colummn and running of motor-driven trolley adopt AC frequency control of
