Ngobubanzi obufanayo bombhobho kunye nobukhulu, amandla aphumayo afanayo, isantya soMatshini wokwenza uMbhobho wentsimbi kwisiza sinokukhawuleza okanye sicothe.
Xa izixhobo zokusila ityhubhu zifana nebhanti yentsimbi, eyona nto iphambili echaphazela isantya se-welding ubukhulu becala yinkqubo ye-welding.Ukuba i-welding ayilungile, i-cracks, i-undercuts, i-slag inclusions, i-infusion, njl.
1. Ukungena okungaphelelanga: i-welding current ephantsi, isantya se-welding esikhawulezayo, i-angle ye-welding gun angle, njl njl.Ukulungelelaniswa okufanelekileyo okwangoku kunye nokulungelelaniswa okuchanekileyo kwe-angle ye-welding gun kunokuphepha ukungena okungaphelelanga.
2. I-oxidation enzima: ngexesha lokuzincibilikisa, isixhobo sokuzalisa uxinzelelo kwi-tube sihluleka ukubonelela ngokukhuselekileyo, kwaye umva we-weld uya kuba ne-oxidized;ukhuseleko olulambathayo lwedama elinyibilikisiweyo kunye nokuphela kocingo lwe-welding ngexesha lenkqubo ye-welding, okanye ukungcola kwe-oxidation kumphezulu wocingo lwe-welding kuya kuba njalo.
3. Ukufakwa kwe-slag kunye nokufakwa kwe-tungsten: Ngethuba lenkqubo ye-welding, ukuba ukuphela kocingo lwe-welding lushiya indawo yokukhusela i-argon ngexesha lenkqubo yokushisa ephezulu, iya kuba ne-oxidized emoyeni.Xa uphinda u-welding, isiphelo socingo oluyi-oxidized alucocwa kwaye luthunyelwe kwi-melting Echibini, kugwetywa ukuba i-slag ifakwe kuvavanyo lokuphuka;ukuba ubude be-electrode ye-tungsten bukhulu kakhulu, itotshi ye-welding ayiyi kuzinza.Emva kokuba i-electrode ye-tungsten kunye nocingo lwe-welding okanye i-electrode ye-tungsten kunye ne-pool etyhidiweyo idibene, ukuwelda akupheli, okukhokelela ekufakweni kwe-tungsten.
4. I-Concave: Ngethuba lenkqubo ye-welding, i-torch ijika kakhulu, ukwenzela ukuba ukushisa kwe-arc akukwazi ukugxininiswa kwingcambu, okubangela ukuba i-concave phenomenon apho i-back weld iphantsi kunomgangatho wesiqwenga sovavanyo.Ubushushu be-arc bugxininiswe kwingcambu kangangoko, kwaye ucingo lwe-welding olungaphezulu lusetyenziswa kwindawo ye-welding ephezulu ukuphepha i-concave.
