  • Study of hollow cathode penetrating Arc Welding technology
    Journal of Materials Processing Technology, 2002
    Co-Authors: Liu Zhihua, Zhao Qing, Li Deqing

    Abstract:

    Abstract In this paper, a method of hollow cathode penetrating Arc Welding technology is presented in detail. In the vacuum condition, hollow cathode penetrating Arc Welding technology differs from fusion Arc Welding technology in better weld formation and narrower welds, as well as a larger technology margin. The weld formation of titanium alloys is preliminarily analyzed. Also, the Welding technology margin is calculated and compared. Finally, initial study conclusions are addressed.

  • Submerged Arc Welding Procedure Improvement Based on Human-Machine Operation Analysis
    2010 3rd International Conference on Information Management Innovation Management and Industrial Engineering, 2010
    Co-Authors: Haiqing Guo

    Abstract:

    Submerged Arc Welding is a kind of Welding methods. Its Arc burns under the Welding flux layer. The working condition of submerged Arc Welding is relatively good. What’s more, the productivity of Welding is higher than other Welding methods. However, there are always some bottlenecks in submerged Arc Welding procedures due to operators’ lacking of standardization and the unreasonable positioning. In order to solve this problem, there are usually two ways. One way is to reposition and to reprogram, and the other is to use relevant technologies of industrial engineering. Aiming at the existed problems in the submerged Arc Welding procedure in an industrial enterprise, according to ECRS(elimination, combine, rearrange, simplify) principle, this paper applied human-machine operation analysis to make operator, Welding machine and tools scientifically combined and reasonably arranged, the purpose of making process reasonably and human-machine coordinated is achieved. Through the improvement, the operation time consumption was reduced by 40.89%, and the productivity of the submerged Arc Welding was greatly improved.
