Research status and application progress of narrow gap welding technology for thick plates
Narrow gap welding technology has become the first choice for welding thick plate structures in modern indus-trial production.Its technical and economic advantages de-termine it to become one of the main directions of the future development of thick plate welding technology.In recent years,with the continuous exploration and research and the de-velopment of scientific and technological workers,a variety of narrow gap welding methods have emerged.In this paper,nar-row gap welding manufacturing technology is systematically described,introducing the narrow gap welding manufacturing technology such as electric arc welding,laser welding,and laser-arc hybrid welding.Meanwhile,this paper outlines the factors influencing the quality and efficiency of the manufac-turing process of narrow gap welding with different heat sources,and summarizes the process characteristics and applic-ation areas of narrow gap welding with different heat sources.Subsequently,combined with the development status of re-lated technologies at home and abroad,this paper summarizes the problems faced by narrow gap welding manufacturing tech-nology and puts forward subsequent development proposals,with a view to providing references for researchers in related fields.
