Bíodh dhá chineál le haghaidh cóimhiotal nicile
Leictreoidí láimhe agus sreang soladach
Tabhair faoi deara: Tá comhéifeacht leathnú teirmeach copair mór, agus tarlaíonn strus crapadh mór le linn an tsoladú, rud a fhágann scoilteanna agus dífhoirmiú. Therefore, the assembly gap should be wide and the groove angle should be large. Multi-point temporary positioning spot welding can also be used. In order to obtain excellent welds, Before welding, the oxide, grease and other dirt on the edge to be welded should be removed
