Zvikonzero zvekuumbwa kweimwe kaviri-sided undercut yeyakadzika arc welded simbi pombi

Welding wire joint

Nekuda kwekuchinja kwedhayamita uye kutsvedzereka kwejoint yewaya, kumhanya kwewaya kunozongoerekana kwachinja kana waya yekubatanidza ichipfuura nepavhiri rekudya rewaya, nekudaro zvichikonzera shanduko yekukurumidza mumagetsi emagetsi uye kumhanya kwekunyungudika, kuwedzera kamwe kamwe kweweld. dziva uye simbi yakanyungudutswa Kusakwana kuwedzera kunogona kukonzera imwe kaviri undercut pane ino solder joint.

Welding tsanangudzo

Mumamiriro ezvinhu akajairwa, hapazove nekuchinja kukuru mune welding yakatarwa panguva yekuenderera mberi kwekugadzirwa.Naizvozvo, undercuts haizoitike panguva yakajairika kugadzirwa.Nekudaro, pasi pesimba rekunze kwesimba rekupa, iyo welding ikozvino uye voltage inogona zvakare kungoerekana yavepo, uye mhedzisiro yekuchinja kwekamwe kamwe inozotungamira mukuitika kwe undercuts.

Instant short circuit

Dzimwe nguva nekuda kweburr pamupendero webhodhi kana simbi burr yakasanganiswa mukuyerera, kapfupi dunhu rinoitika padanho rekusangana panguva yeyakajairwa welding process.Iyo pfupi pfupi yedunhu ichaita kuti welding ikozvino uye voltage ichinje ipapo, izvo zvinozopedzisira zvatungamira kune undercut.Kurapa kwekamwe kaviri undercut kwakafanana nenzira yekurapa imwe chete undercut, iyo inogona kugadziriswa nekukuya kana kugadzirisa.
