摘　　要：高压MIG焊接是可适用于1000m水深环境的高效焊接技术。为解决深水环境下焊接熔滴过渡受阻问题，将外加磁场控制技术创造性地应用于深水高压情况下MIG焊接，通过外加磁场能量来平衡介质压力的影响，并采用有限元方法对影响深水环境下焊接区域的外加磁场分布进行计算，分析和仿真。结果表明，合理设置外加纵向磁场的各参数可简便有效地控制焊接质量，满足各种场合的焊接要求，为进一步实现高压自动焊接技术奠定基础。Hyperbaric MIG welding is a high efficiency welding technology and applicable to 1000 m depth of water environment. To solve the deep water environment welding welding transition, an additional magnetic field control technology is used in deep water creative high pressure cases MIG welding, through additional magnetic energy to balance the influence of media pressure, and using the finite element method the deep water environment of welding area additional magnetic field distribution is calculated, analyzed and simulated. The results show that, if the parameters of the adittional magnetic field is set up reasonably then the welding quality can be controled simply and effectively and met various occasions welding requirements, for further realization of high pressure automatic welding technology lay the foundation.
