Scientific research personnel through five years of painstaking research, master the composite pipe laser/arc welding technology and key technology, test prototype developed is suitable for high grade, large diameter pipeline laser/arc welding equipment, this equipment has the advantages of compact structure, small volume, light weight, can lead the progress of our country's steel pipeline girth weld welding technology.Major technical characteristics of the study is to use laser/arc composite one-sided welding of large welding penetration, forming good, one-time welding layer thickness of thick advantages, combined with its high welding speed, reduce the number of pure electric arc welding filler layer and metal filling amount, thus greatly save stand-up welding time and weld material, the equipment investment, raise the efficiency and quality of pipeline welding construction, shorten the construction period, reduce construction cost.


At present, the oil and gas pipeline girth weld laser/arc welding machine prototype through continuous improvement, has industrial application conditions.
