Ama-alloys e-Copper asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa ye-conductivity yawo kagesi enhle kakhulu, i-thermal conductivity, nokumelana nokugqwala. Lesi sihloko sigxile kumasu okushisela ama-alloys ethusi usebenzisa umshini wokushisela i-medium frequency inverter spot welding. Ukuqonda ukucatshangelwa okuqondile kanye nezinqubo zokushisela ama-alloys ethusi kubalulekile ekuzuzeni ama-welds aphumelelayo futhi athembekile ekusetshenzisweni kwe-alloy yethusi.
Ukukhetha Okubalulekile:
Khetha i-alloy yethusi efanelekile yohlelo oluhlosiwe. Ama-alloys ethusi abonisa izakhiwo ezihlukene zemishini nezici zokushisela, ngakho-ke kubalulekile ukukhetha ingxubevange ehlangabezana nezidingo ezidingekayo. Ama-alloys ethusi avamile asetshenziswa ekushiseleni ahlanganisa ithusi, ithusi, nama-alloys e-copper-nickel.
Idizayini Ehlangene:
Khetha idizayini ehlangene efanelekile eqinisekisa ukulingana nokuqondanisa kwezingxenye zengxube yethusi. Umklamo ohlangene kufanele unikeze ukufinyelela okwanele kokubekwa kwe-electrode futhi wenze kube lula ukusatshalaliswa kokushisa okusebenzayo ngesikhathi sokushisela. Izinhlobo ezijwayelekile ezihlangene zama-alloys ethusi zihlanganisa amalunga ethanga, amalunga e-butt, nama-T-joints.
Ukukhethwa kwe-Electrode:
Khetha ama-electrode enziwe ngezinto ezihambisana nama-alloys ethusi. Ama-electrode ethusi e-Tungsten avame ukusetshenziswa ngenxa yokumelana nokushisa okuphezulu kanye nokuhamba kahle kukagesi. Khetha usayizi we-electrode nokuma okusekelwe ekwakhiweni okuhlangene okuqondile kanye nezidingo zokushisela.
Amapharamitha we-Welding:
Lawula imingcele yokushisela ukuze uzuze imiphumela emihle lapho ushisela ama-alloys ethusi. Amapharamitha afana ne-welding current, isikhathi, amandla e-electrode, nesikhathi sokupholisa kufanele kulungiswe ngokusekelwe ku-alloy yethusi ethize eshiselwe. Yenza ama-weld okulinga ukuze unqume amapharamitha afanelekile ahlinzeka ngokuhlanganisa okuhle nokungena ngaphandle kokufaka ukushisa okukhulu.
I-Shielding Gas:
Sebenzisa igesi eyisivikelo efanelekile ngesikhathi senqubo yokushisela ukuze uvikele i-molten weld pool kanye ne-electrode ekungcoleni komoya. Amagesi angasebenzi njenge-argon noma i-helium avame ukusetshenziswa njengamagesi okuvikela ama-alloys ethusi. Qinisekisa ukumbozwa kahle kwegesi ukuvimbela i-oxidation futhi uzuze ukushisela okuhlanzekile nokuzwakalayo.
I-Pre-weld kanye ne-Post-weld Heating:
Ukushisa kwangaphambi kwe-weld kanye ne-post-weld kungase kudingeke ukuze ama-alloys ethusi athile alawule umjikelezo oshisayo futhi anciphise ukuhlanekezela. Ukushisa ilunga kungasiza ekunciphiseni ingozi yokuqhekeka, kuyilapho ukufudumeza kwangemuva kwe-weld kungakhulula ukucindezeleka okusalayo futhi kuthuthukise ikhwalithi yokushisela iyonke. Landela izinqubo zokushisisa ezinconyiwe zengxubevange yethusi ethile eshiselwayo.
Ukuhlanzwa Nokuqedwa Kwangemva Kwe-Weld:
Ngemva kokushisela, susa noma yiziphi izinsalela ze-flux, ama-oxide, noma ukungcola endaweni yokushisela usebenzisa izindlela zokuhlanza ezifanele. Lokhu kuqinisekisa ubuqotho nokubukeka kobuhle bejoyinti elishiselwe. Izinqubo zokuqeda ezifana nokugaya noma ukupholisha zingaqashwa ukuze kuzuzwe ubushelelezi obufunwayo nokubukeka kwendawo.
Ama-alloys ethusi okushisela anomshini wokushisela amabala okushintshashintshashintshayo okuphakathi kudinga ukucatshangelwa ngokucophelela kokukhethwa kwezinto, ukwakheka okuhlanganyelwe, ukukhetha ama-electrode, imingcele yokushisela, ukusetshenziswa kwegesi yokuvikela, kanye nezinqubo zokushisisa zangaphambi nangemuva kwe-weld. Ngokulandela lezi zindlela, ama-welders angakwazi ukufeza ama-welds athembekile futhi aphezulu ekusetshenzisweni kwe-alloy yethusi. Imikhuba yokushisela efanele ifaka isandla ekuthembekeni kwesakhiwo, ukuqhutshwa kukagesi, nokumelana nokugqwala kwezingxenye ezishiselwe, okuqinisekisa ukusebenza kwazo nokuphila isikhathi eside ezimbonini ezihlukahlukene.
