Abashiseli basebenzisa ukushisela kwe-MIG ezimbonini eziningi - ezokwakha, ezokukhiqiza, ezakha imikhumbi nezitimela ukubala ezimbalwa. Nakuba kuyinqubo evamile, idinga ukunakwa emininingwaneni, futhi kuyasiza ukwazi amagama abalulekile ahlobene nayo. Njenganoma iyiphi inqubo, ukuqonda okungcono, kuba ngcono imiphumela.
Ukuzalela izinyoni
Ukuhlangana kwentambo yokushisela kumaroli wokushayela wesiphakeli sezintambo. Lokhu ngokuvamile kwenzeka uma intambo ingenayo indlela yokudla ebushelelezi ngenxa yokuthi ulayini usikwa waba mfishane kakhulu, kusetshenziswa ulayini kasayizi ongalungile noma ithiphu, noma izilungiselelo ezingalungile zedrayivu. Xazulula le nkinga ngokunquma ilineni ngendlela efanele futhi uqinisekise ukuthi indlela yokuphakelayo yocingo ibushelelezi futhi iqonde ngangokunokwenzeka.
I-Burnback
Kuvela uma ucingo luncibilika ngaphakathi kwethiphu yokuxhumana ngaphambi kokufinyelela kucezu lokusebenza. Kubangelwa ukuthintana okungalungile-ithiphu-kuya-kumsebenzi ibanga (CTWD) — ibanga eliphakathi kokuphela kwethiphu kanye nesisekelo sensimbi — noma isivinini sokuphakela kwentambo esinensa kakhulu (WFS). Kungase futhi kubangelwe ulayini ongasikwe ngokungalungile kanye nemingcele engalungile. Lungisa inkinga ngokwandisa i-WFS, ukulungisa i-CTWD, ukuphungula i-liner ngokwezincomo zomenzi kanye nokuguqula imingcele ye-weld.
Izinga lokubeka
Isho ukuthi ingakanani insimbi yokugcwalisa efakwa kujoyinti lokushisela esikhathini esithile esinqunyiwe, esilinganiswa ngamaphawundi noma amakhilogremu ngehora (lbs/hr noma kg/hr).
Ukungaqhubeki
Iphutha esakhiweni se-weld engenzi ingozi yokwehluleka. Ihlukile ekushiyekeni kwe-weld okungathinta ubuqotho be-weld uma isisensimini.
Duty umjikelezo
Isho iphesenti lesikhathi esikhathini esiyimizuzu eyi-10 isibhamu singasetshenziswa ngesikhathi esithile (isikhathi se-arc-on) ngaphandle kokushisa kakhulu ukusiphatha noma ukushisa ngokweqile. Umjikelezo womsebenzi wesibhamu uthintwa uhlobo lwegesi evikelayo esetshenziselwa ukushisela. Isibonelo, isibhamu se-MIG singalinganiswa kumjikelezo wemisebenzi engu-100% ngegesi evikela i-CO2 engu-100%, okusho ukuthi singashisela yonke imizuzu eyi-10 ngaphandle kwezinkinga; noma ingaba nesilinganiso sesibhamu esingu-60% womjikelezo wokusebenza namagesi axubile.
Isandiso se-Electrode
Ibanga lentambo yokushisela lisuka ekugcineni kwethiphu yokuxhumana liye lapho intambo incibilika khona. Njengoba ukwanda kwe-electrode kwanda, i-amperage iyancipha, okunciphisa ukungena okuhlangene. Futhi okuvame ukubizwa ngokuthi ibanga le-tip-to-workpiece.
Indawo ethinteke ukushisa
Okuvame ukubizwa ngokuthi i-HAZ, ingxenye yezinto eziyisisekelo ezungeze i-weld engakancibiliki kodwa ishintshe izakhiwo zayo ezingeni le-microstructure ngenxa yokufaka ukushisa. Ukuqhekeka kungenzeka lapha.
Ukuhlanganisa okungaphelele
Okubizwa nangokuthi ukuntuleka kwe-fusion, kwenzeka lapho i-weld ihluleka ukuhlanganisa ngokuphelele ne-base material noma i-weld pass yangaphambilini ku-multi-pass welding. Ngokuvamile, kuwumphumela we-engeli yesibhamu ye-MIG engalungile.
I-Porosity
Ukungaqhubeki okufana nomgodi okwenzeka lapho igesi ivaleleka ku-weld ekuqinisweni kwechibi lokushisela elincibilikisiwe. Ivamise ukubangelwa ukumbozwa kabi kwegesi yokuvikela noma ukungcoliswa kwezinto eziyisisekelo.
Ukungena kwe-weld
Kubhekisela ebangeni lamafuse e-weld ngaphansi kobuso bezinto eziyisisekelo. Ukungena kwe-weld okungaphelele kwenzeka lapho i-weld ingagcwalisi ngokuphelele impande yelunga.
