在成功地研究并开发了薄壁构件低应力无变形焊接新技术的基础上，把靠预置温度场静态控制焊接应力与变形的方法发展到动态控制法，这一新构思所形成的动态控制焊接应力与变形的新技术的原理在于：不再依赖预置温度场，而是直接利用电弧在薄壁构件上所形成的焊接温度场，建立一个特殊构造的热潭跟随电弧，构成“热源－热潭”多源系统，在熔池后的高温焊缝区产生强烈的局部急冷拉伸作用，控制和补偿焊接时产生的压缩塑性变形。达到薄壁构件低应力无变形的焊接效果。
Based on the successful research and development of new technology of low-stress non-deformation welding of thin-walled components, the method of static control of welding stress and deformation by the preset temperature field has been developed to the dynamic control method. The dynamic control The principle of welding stress and deformation of the new technology is: no longer rely on the preset temperature field, but the direct use of arc welding in the thin-walled components formed on the temperature field, the establishment of a special structure of the hot pool to follow the arc, constitute a “heat - Hot pool ”multi-source system in the weld pool after the weld zone has a strong local cold quenching tensile control, welding and compensation to compensate for the compression of plastic deformation. Thin-walled components to achieve low-stress deformation without welding effect.
