Amaphuzu alandelayo azonakwa lapho usebenzisa i-argon arc welding:
1. Ukunikezwa kwamandla okunezici zangaphandle eziqondile kuyamukelwa, futhi i-polarity enhle yamukelwa ku-DC (intambo yokushisela ixhunywe esigxotsheni esibi).
2. Ngokuvamile kulungele ukushiswa kwamapuleti amancane angaphansi kuka-6mm, anezici zokwakheka okuhle kwe-weld kanye ne-welding deformation encane.
3. Igesi evikelayo i-argon ngobumsulwa ≥ 99.95%.Lapho i-welding current ingu-50 ~ 150A, ukugeleza kwe-argon kungu-6 ~ 10L / min, futhi uma yamanje ingu-150 ~ 250A, ukugeleza kwe-argon kungu-12 ~ 15L / min.Ukucindezela okuphelele ebhodleleni akufanele kube ngaphansi kuka-0.5MPa ukuqinisekisa ukuhlanzeka kokugcwalisa i-argon.
4. Ubude be-electrode ye-tungsten ephuma emlonyeni wegesi kungcono kakhulu kube ngu-4 ~ 5mm, 2 ~ 3mm ezindaweni ezinezivikelo ezingezinhle njengokushisela i-fillet, 5 ~ 6mm ezindaweni ezinomsele ojulile, futhi ibanga ukusuka kubhobho ukuya ekusebenzeni ngokuvamile asikho ngaphezu kuka-15mm.
5. Ukuze uvimbele ukuvela kwe-welding pores, ibala lamafutha, isikali kanye nokugqwala ezindongeni zangaphakathi nangaphandle zezingxenye ze-welding kufanele zihlanzwe.
6. Ubude be-arc bokushisela insimbi engagqwali bungu-1 ~ 3mm, futhi umphumela wokuvikela awumuhle uma umude kakhulu.
7. Ngesikhathi sokusekela izinqe, ukuze kuvinjwe ingemuva le-weld bead engaphansi ekubeni i-oxidized, ingemuva nalo lidinga ukuvikelwa ngegesi.
8. Ukuze kuvikelwe kahle ichibi lokushisela nge-argon futhi kube lula ukusebenza kokushisela, i-engeli ephakathi komugqa ophakathi we-tungsten electrode kanye ne-workpiece endaweni yokushisela kufanele igcinwe ku-75 ~ 85 °, futhi i-engeli ehlanganisiwe phakathi kokugcwalisa. ucingo kanye nendawo yokusebenza kufanele kube kuncane ngangokunokwenzeka, ngokuvamile kube ngaphansi kuka-10 ° odongeni ukujiya futhi kungabi ngaphezu kuka-1mm.Ukuze uqinisekise ukucinana kwe-weld, naka izinga elihle lokuhlangana kwelunga, futhi ugcwalise ichibi elincibilikisiwe ngesikhathi sokuma kwe-arc.
