Yini Ebangela Ukubhoboka Kwezimbobo Ekushiseni Kwe-MIG?

Uma kushiselwa, umgomo ukudala isibopho esiqinile nesingenamthungo phakathi kwezingcezu ezimbili zensimbi. Ukushiselwa kwe-MIG kuyinqubo eguquguqukayo engasetshenziswa ukushiselwa izinsimbi ezahlukene. Ukushiselwa kwe-MIG kuyinqubo enhle yokuhlanganisa izinto ndawonye. Kodwa-ke, uma kusetshenziswa izilungiselelo ezingalungile, i-porosity ingafakwa ku-weld. Lokhu kungabangela izinkinga ngamandla kanye nobuqotho be-weld.

Kulesi sihloko, sizobheka ezinye zezimbangela zokubola kwe-MIG kanye nendlela yokukuvimbela.

Yini Ebangela Ukubhoboka Kwezimbobo Ekushiseni Kwe-MIG?

Ukugoba komoya uhlobo lokukhubazeka kokugoba komoya okungaba khona kuma-weld. Kubonakala njengemigodi emincane ku-weld futhi kungenza buthaka isibopho phakathi kwezingcezu ezimbili zensimbi. Ukugoba komoya kungabangelwa yizinto ezahlukahlukene, okuhlanganisa:

1) Ukuhlanganiswa Okungaphelele

Lokhu kwenzeka lapho i-arc yokushisela ingancibilikisi ngokuphelele insimbi eyisisekelo kanye nezinto zokugcwalisa. Lokhu kungenzeka uma umshini wokushisela ungemisiwe ku-amperage efanele noma uma ithoshi lokushisela lingabanjwanga eduze ngokwanele nensimbi.

2) Ukumbozwa Okubi Kwegesi

Ukushisela kwe-MIG kusebenzisa igesi yokuvikela ukuvikela ukushisela emoyeni nakwezinye izinto ezingcolisayo. Uma ukugeleza kwegesi kuphansi kakhulu, kungenzeka kube nezimbobo. Lokhu kungenzeka uma isilawuli segesi singasethwanga kahle, noma uma kukhona ukuvuza epayipini legesi.

3) Ukuvalelwa Kwegesi

Esinye isizathu sokuvuleka kwegesi ukubanjwa yigesi. Lokhu kwenzeka lapho amabhamuza egesi ebhajwa echibini lokushisela. Lokhu kungenzeka uma ithoshi lokushisela lingabanjwanga nge-engeli efanele noma uma kunegesi yokuvikela eningi kakhulu.

4) Ukungcola kanye nezinto ezingcolisayo

Ukubhoboka kungabangelwa futhi ukungcoliswa kwensimbi eyisisekelo noma izinto zokugcwalisa. Ukungcola, ukugqwala, upende, nezinye izinto ezingcolisayo nakho kungabangela ukubhoboka. Lokhu kungenzeka uma insimbi ingahlanzekile ngaphambi kokushisela, noma uma kukhona ukugqwala noma upende ebusweni. Lokhu kungcola kungavimbela ukushisela ekubopheni kahle kwensimbi.

5) Igesi Yokuvikela Enganele

Esinye isizathu sokuvuleka kwegesi ukungabi negesi yokuvikela eyanele. Lokhu kungenzeka uma kusetshenziswa igesi engalungile enqubweni yokushisela noma uma ukugeleza kwegesi kungamiswanga kahle.

Ungakuvimbela Kanjani Ukuvuleka Kwezimbobo Ezenzekeni Ngesikhathi Senqubo Yokushisela ye-MIG?

Kunezinto ezimbalwa ongazenza ukuze uvimbele ukuvuleka kwe-porosity ngesikhathi senqubo yokushisela i-MIG:

1. Sebenzisa izilungiselelo ezifanele: Qiniseka ukuthi usebenzisa izilungiselelo ezifanele emshinini wakho wokushisela. I-amperage kanye ne-voltage kufanele kubekwe ngokwemiyalelo yomenzi.

2. Sebenzisa igesi efanele: Qiniseka ukuthi usebenzisa igesi efanele enkambisweni yakho yokushisela. I-Argon ivame ukusetshenziselwa ukushisela i-MIG.

3. Ukugeleza kwegesi: Setha izinga lokugeleza kwegesi ngokwemiyalelo yomenzi. Igesi eningi kakhulu noma encane kakhulu ingabangela ukubhoboka.

4. Gcina ithoshi lisekhoneni elifanele: Qiniseka ukuthi ubamba ithoshi ekhoneni elifanele ukuze ugweme ukubhajwa yigesi. Ithoshi kufanele libanjwe ekhoneni elingama-degree ayi-10 kuya kwangu-15 ukusuka ebusweni bensimbi.

5. Sebenzisa insimbi ehlanzekile: Qiniseka ukuthi usebenzisa insimbi ehlanzekile, engangcolisiwe ekushiseleni kwakho. Noma yikuphi ukungcola, ukugqwala, noma upende ongaphezulu kungabangela ukubhoboka.

6. Ukushisela endaweni enomoya omuhle: Ukushisela endaweni enomoya omuhle ukuze ugweme ukubhajwa yigesi. Igesi evikelayo ingabhajwa ezindaweni ezivalekile.

Ukubhoboka kwenhlabathi kungavinjelwa ngokulandela lawa macebiso. Ngokusebenzisa izilungiselelo ezifanele kanye nokushisela endaweni enomoya omuhle, ungagwema le nkinga.

Izindlela Ezivamile Zokulungisa Ama-Porosity Welds

Kunezindlela ezimbalwa ezivamile zokulungisa ama-welds ezithintekile yi-porosity:

1. Ukushisela kabusha: Ikhambi elivamile ukushisela kabusha indawo ethintekile. Lokhu kungenziwa ngokushisela phezu kwendawo ethintekile nge-amperage ephezulu.

2. Ama-Porosity plugs: Elinye ikhambi elivamile ukusebenzisa ama-porosity plugs. Lawa ama-disc amancane ensimbi abekwa phezu kwemigodi eku-weld. Ama-Porosity plugs angathengwa ezitolo eziningi ezithengisa izinto zokushisela.

3. Ukugaya: Enye indlela ukugaya indawo ethintekile bese uyishisela kabusha. Lokhu kungenziwa nge-grinder ebanjwa ngesandla noma nge-angle grinder.

4. Ucingo lokushisela: Elinye ikhambi ukusebenzisa ucingo lokushisela. Lolu ucingo oluncane olusetshenziswa ukugcwalisa imigodi ekushiseleni. Ucingo lokushisela lungathengwa ezitolo eziningi ezithengisa izinto zokushisela.

Ukubhoboka kwesikhumba kungalungiswa ngokusebenzisa enye yalezi zindlela ezivamile zokwelapha. Ngokushisela kabusha indawo noma ukusebenzisa ama-porosity plugs, ungayilungisa inkinga.
