前言焊缝场致跟踪法(参见本刊1982年第九期“焊缝场致跟踪技术研究”一文),特别适用于薄板对接焊缝的自动跟踪。但是,在生产中为了防止薄板焊接变形,需要采用胎具夹紧焊件,并在焊件下面衬以铜垫板。由于铜垫板破坏了焊件电位场的分布规律,从而导致焊缝自动跟踪过程不稳定,甚至不能进行。为探讨垫板材质对焊件电位场分布规律的影响,采用不同材质的垫板进行了焊接自动跟
Foreword Weld field tracking method (see the 1982 issue of 9 “weld field tracking technology research” article), especially suitable for automatic tracking of sheet butt welds. However, in the production of sheet metal in order to prevent welding deformation, the need to use the mold clamping the weldment, and under the welder lined with copper pad. Due to the destruction of the copper plate pad potential distribution of the electric field, resulting in the weld tracking process is not stable, or even can not. In order to discuss the influence of the material of backing plate on the distribution of potential field of the welding part,
