本機(jī)采用船形埋弧焊，焊接時(shí)工件不動(dòng)，門(mén)架介行走，門(mén)架移動(dòng)采用變頻調(diào)速；橫梁配備有二組導(dǎo)柱各帶一套焊接機(jī)頭，用電動(dòng)機(jī)驅(qū)動(dòng)來(lái)調(diào)節(jié)上下位移。用首動(dòng)調(diào)節(jié)裝置來(lái)調(diào)節(jié)左右位移；導(dǎo)弧機(jī)構(gòu)對(duì)焊接進(jìn)行機(jī)械式跟蹤，焊縫質(zhì)量高；焊藥可自動(dòng)回收，節(jié)省人力。

using cymbiform submerged arc welding; when welding, workpiece is fixed, but portal frame is, moved and the speed of moving is controlled by frequency varation; equipping aset of wedljng head at each2 groups of guiding post on the beam; using electric dynamo to drive to adjust shrting up and down; using manual adjusting device to adjust shifting left and right; processing mechanictracing the welding line with guiding arc mechanism, wich can get high quality of welding line; automatically recycling the solder, which can save the labor.
