100t阳极炉加长改造体环缝的全位置自动焊

Welding in all-position for rebuilding hemming-stitch of 100t positive-stove

介绍了QWH-Ⅱ型全位置自动焊机的构成及工作原理。采用该焊机焊接了100t阳极炉加长改造4条炉体环缝,结果表明焊接质量大大提高,焊工的劳动强度大大降低,生产效率比手工电弧焊提高3～4倍。

This article introduces the structure and working principle of QWH-Ⅱall-position auto welding machine.By welding the100t positive-stove for making the4hemming-stitches longer,the experiment shows that the welding quality is enhanced,work force is reduced and the production efficiency is improved for3-4times than metal arc welding.
