| Abstract: | When big current is used in strip electroslag overlap welding,the parallel current unit has magnetic shrink effect, this will cause the welding seams seriously undercut. A principle to make use of outside magnetic field against welding seam undercut were specified. On the bases of effect analysis of different ways of magnetic control, the magnetic control equipment of the electric coil convenient to be adjusted was tested and produced. The tests of magnetic plate, magnetic current, and the affective test of the welding specification to the magnet control were completed, and the problems occurred in manufacture were summarized. |
