TIG ukuwelda
Le yi-electrode enganyibilikiyo yegesi enert ekhuselweyo, esebenzisa i-arc phakathi kwe-electrode ye-tungsten kunye ne-workpiece ukunyibilikisa isinyithi ukwenza i-weld. I-electrode ye-tungsten ayinyibiliki ngexesha lenkqubo ye-welding kwaye isebenza kuphela njenge-electrode. Ngexesha elifanayo, i-argon gas ifakwe kwi-nozzle yetotshi yokukhusela. Kwakhona kunokwenzeka ukongeza isinyithi njengoko kufuneka.
Kuba igesi enganyibilikiyo kakhulu ekhuselwe i-arc welding inokulawula kakuhle igalelo lobushushu, yeyona ndlela igqwesileyo yokudibanisa isinyithi kunye nentsimbi esezantsi. Le ndlela ingasetyenziselwa ukudibanisa phantse zonke isinyithi, ngokukodwa i-aluminium ye-welding, i-magnesium kunye nezinye isinyithi ezinokuthi zenze i-oxides ephikisayo kunye neentsimbi ezisebenzayo ezifana ne-titanium kunye ne-zirconium. Umgangatho we-welding wale ndlela yokuwelda uphezulu, kodwa xa kuthelekiswa nezinye i-arc welding, isantya sayo se-welding siyacotha.
Ukuwelda kwe-MIG
Le ndlela ye-welding isebenzisa ukutshisa kwe-arc phakathi kocingo lwe-welding oluqhubekayo kunye ne-workpiece njengomthombo wobushushu, kwaye i-arc ye-inert ekhuselekile efakwe kwi-arc ye-welding isetyenziselwa ukuwelda.
Igesi ekhuselayo edla ngokusetyenziswa kwi-MIG welding yile: i-argon, i-helium okanye umxube wezi gesi.
Inzuzo ephambili ye-MIG ye-welding kukuba inokudityaniswa ngokulula kwiindawo ezahlukeneyo, kwaye ikwanenzuzo yesantya esikhawulezayo se-welding kunye nezinga eliphezulu lokubeka. I-MIG welding ifanelekile kwinsimbi engenasici, i-aluminium, i-magnesium, ubhedu, i-titanium, i-zirconium kunye ne-nickel alloys. Le ndlela yokuwelda inokusetyenziselwa ukuwelda indawo ye-arc.
