La manqaku alandelayo aya kuqwalaselwa xa usebenzisa i-argon arc welding:
1. Ukunikezelwa kwamandla kunye neempawu zangaphandle ezithe nkqo zamkelwa, kwaye i-polarity echanekileyo yamkelwa kwi-DC (i-wire welding ixhunyiwe kwi-pole negative).
2. Ngokuqhelekileyo ifanelekile ukuthungwa kwamacwecwe amancinci angaphantsi kwe-6mm, kunye neempawu zokwenza i-weld enhle kunye ne-welding deformation encinci.
3. Igesi yokukhusela i-argon kunye nobunyulu ≥ 99.95%.Xa i-welding yangoku i-50 ~ 150A, ukuhamba kwe-argon yi-6 ~ 10L / min, kwaye xa ngoku i-150 ~ 250A, ukuhamba kwe-argon yi-12 ~ 15L / min.Uxinzelelo olupheleleyo kwibhotile aluyi kuba ngaphantsi kwe-0.5MPa ukuqinisekisa ukucoceka kokuzaliswa kwe-argon.
4. Ubude be-electrode ye-tungsten ephuma kumbhobho werhasi kukhethwa ukuba yi-4 ~ 5mm, 2 ~ 3mm kwiindawo ezikhuselwe kakubi ezifana ne-fillet welding, 5 ~ 6mm kwiindawo ezine-groove enzulu, kunye nomgama ukusuka kwi-nozzle ukuya ekusebenzeni. ngokubanzi akukho ngaphezu kwe-15mm.
5. Ukuze kuthintelwe ukwenzeka kwe-welding pores, i-oil stain, isikali kunye ne-rust kwiindonga zangaphakathi nangaphandle zeengxenye ze-welding kufuneka zihlambuluke.
6. Ubude be-arc ye-welding yensimbi engenasici yi-1 ~ 3mm, kwaye umphumo wokukhusela awulungile ukuba ude kakhulu.
7. Ngexesha lokuxhaswa kwe-butt, ukwenzela ukukhusela umva we-weld bead engaphantsi kwi-oxidized, umva nawo kufuneka ukhuselwe ngegesi.
8. Ukuze ukhusele i-welding pool kakuhle kunye ne-argon kwaye uququzelele ukusebenza kwe-welding, i-angle phakathi komgca ophakathi we-electrode ye-tungsten kunye ne-workpiece kwindawo ye-welding iya kugcinwa ngokubanzi kwi-75 ~ 85 °, kunye ne-angle edibeneyo phakathi kokugcwalisa. ucingo kunye nomphezulu womsebenzi uya kuba mncinci kangangoko kunokwenzeka, ngokubanzi ube ngaphantsi kwe-10 ° yobukhulu bodonga kwaye ungabi ngaphezu kwe-1mm.Ukuze uqinisekise ukuqina kwe-weld, nikela ingqalelo kumgangatho omhle wokudibanisa umdibaniso, kwaye ugcwalise i-pool etyhidiweyo ngexesha lokumisa i-arc.
