凸起变形是船体焊接结构中常见的缺陷,相对于传统变形校正法,电动加工处理法有诸多优势。为了研究电动法对凸起类变形的影响,通过点状处理法、环形处理法和螺旋处理法等三种电动法处理АМг6铝合金和Ст3低碳钢试样。结果表明,点状处理法能耗最小,环形处理法和螺旋处理法的效率近似,但后者能耗更低,且螺旋法降低凸起变形的效果最好。通过对比分析,电动法的能耗远低于传统方法,符合耗能最小标准。采用铜衬垫的电动处理可消除其对加工金属结构表面的影响。
The convex deformation is a common defect in the hull welding structure. Compared with the traditional deformation correction method, the electric machining method has many advantages. In order to study the influence of the electric law on the deformation of the bulge, the АМг6 aluminum alloy and the Ст3 low carbon steel sample were processed by three electric methods: point-like method, ring-shaped method and spiral method. The results show that the point-like method consumes the least energy, and the efficiency of the ring-shaped method and the spiral method is similar, but the latter method consumes less energy. The helical method has the best effect of reducing the bulge deformation. Through comparative analysis, electric law energy consumption is much lower than the traditional method, in line with the minimum energy consumption standards. Electric treatment with copper liners eliminates their effect on the surface of the metalworking structure.
