I-TIG welding yasungulwa okokuqala eMelika (USA) ngo-1936, eyaziwa ngokuthi i-Argon arc welding.I-TIG ivumela amajoyinti ashiselwe ekhwalithi ephezulu ukuthi akhiqizwe ngezisekelo zegesi ye-inert enemiphumela yokushisela ehlanzekile.Le ndlela yokushisela iyinqubo yokushisela eyinhloso yonke ngokuphathelene nezinto ezisetshenzisiwe, ukushuba kodonga, kanye nezikhundla zokushisela.
Izinzuzo zale ndlela yokushisela ayikhiqizi nhlobo isipatha kanye nezinto ezingcolisayo ezimbalwa kuyilapho iqinisekisa ilunga eliphezulu elishiselwe uma lisetshenziswa kahle.Ukuphakelwa kwezinto ezisetshenziswayo zokushisela kanye nezamanje akuxhumene, ngakho-ke lokhu kwenza i-TIG ifanelekele ukudlula kwezimpande zokushisela kanye nokushisela okwendawo.
Kodwa-ke, ukushisela kwe-TIG kudinga umshiseli oqeqeshwe kahle ukuze ayisebenzise ngesandla esinekhono nolwazi lokusetshenziswa okufanele kwe-voltage ne-amperage.Labo bazosekela umphumela wokushisela we-TIG ohlanzekile nongcono kakhulu.Futhi ngicabanga ukuthi lezi yiphuzu lokungalungi kokushisela kwe-TIG.
Njengoba ubona kuleso sithombe, ngemva kokucindezela inkinobho yethoshi igesi iqala ukugeleza.Futhi lapho ichopho lethoshi lithinta ubuso bensimbi, kwenzeka isifunda esifushane.ngenxa yokuminyana okuphezulu kwamanje ekugcineni kwethoshi, insimbi iqala ukuhwamuka lapho kuxhunywana khona futhi i-arc iyavutha, vele, imbozwe igesi evikelayo.
UKUSETHA IMICINDEZI YEGAS / UKUGULA
Izinga lokugeleza kwegesi liku-l/min futhi lincike kusayizi wechibi lokushisela, ububanzi be-electrode, ububanzi benobhobho yegesi, ibanga lombhobho endaweni yensimbi, ukugeleza komoya okuzungezile kanye nohlobo lwegesi evikelayo.
Umthetho olula wukuthi amalitha ama-5 kuya kwayi-10 egesi evikelayo kufanele engezwe ku-argon njengegesi evikelayo kanye namadiamitha e-electrode esetshenziswa kakhulu e-tungsten, ngesilinganiso sika-1 kuya ku-4 mm ngomzuzu.
INDAWO YOKUTHENGISA
Njengaku-MIG Welding, isikhundla sethoshi, lapho usebenzisa indlela ye-TIG Welding, nayo ibaluleke kakhulu.Ukuma kwethoshi kanye nenduku ye-electrode kuzothinta imiphumela ehlukene yokushisela.
I-Electrode ngokwayo iphinde ibe yinto esetshenziswayo yokushisela esetshenziswa ngesikhathi sokushisela i-TIG.Izinto ezisetshenziswayo zokushisela ngokuvamile zikhethwa ngendlela efanayo nohlobo lwensimbi.Kodwa-ke, ngenxa yezizathu ze-metallurgical, kuyadingeka ukuthi izinto ezisetshenziswayo zokushisela ziphambuke ensimbi yomzali lapho kusetshenziswa izakhi ezithile ze-alloying.
Buyela endaweni yethoshi.Ungasebenzisa izikhundla ezahlukene zethoshi ye-TIG kanye nenduku ye-electrode ngenkathi ushisela amalunga ensimbi ahlukahlukene.Ngakho ukuma kwethoshi kuncike ohlotsheni lwamalunga ensimbi.Ngisho ukuthi kukhona amajoyinti ensimbi angu-4 afana nalawa:
T- Joint
Ikhona Elihlangene
I-Butt Joint
I-Lap Joint
Ungasebenzisa ezinye zalezi zikhundla zethoshi emisebenzini ofuna ukuyiqeda.Futhi uma ujwayele izikhundla ezihlukahlukene zensimbi zokuhlanganisa ithoshi, ungafunda ngemingcele ye-welding.
IMIPHAKATHI YOKUSHISA
Uma ukhetha amapharamitha we-welding, kufanele kuqashelwe ukuthi i-current kuphela isethwe emshinini wokushisela.I-voltage inqunywa ubude be-arc, obugcinwa yi-welder.
Ngakho-ke, ubude be-arc obukhulu budinga i-voltage ephezulu ye-arc.Umshini wokushisela wama-amperage angu-45 nge-mm ngayinye yogqinsi lwensimbi usetshenziswa njengenani eliyireferensi lamanje elanele ukuze insimbi yokushisela ingene ngokugcwele.
