Kwi-MIG yezicelo ze-welding, ukuba nendlela yokutyisa ucingo olugudileyo kubalulekile. I-wire welding kufuneka ikwazi ukondla ngokulula kwi-spool kwi-feeder ngokusebenzisa i-pin yamandla, i-liner kunye nompu kunye nokunyuka ukuya kwi-tip yoqhagamshelwano ukuseka i-arc. Oku kuvumela umqhubi we-welding ukuba agcine amanqanaba angaguqukiyo emveliso kwaye afezekise umgangatho omhle we-weld, ngelixa ekwanciphisa ixesha lokunciphisa iindleko zokulungisa iingxaki kunye nokusebenza kwakhona okunokwenzeka.
Nangona kunjalo, kukho imiba emininzi enokuphazamisa ukondla ngocingo. Ezi zinokubangela iingxaki ezininzi, kuquka i-arc ephosakeleyo, ukutshisa (ukwenziwa kwe-weld okanye kwi-tip yoqhagamshelwano) kunye ne-birdnesting (i-tangle yocingo kwii-drive rolls). Kubaqhubi abatsha be-welding abanokuthi bangaqhelani nenkqubo ye-MIG ye-welding, ezi ngxaki zinokuphazamisa ngakumbi. Ngethamsanqa, kukho amanyathelo okuthintela lula iingxaki kunye nokudala indlela yokutya ethembekileyo yocingo.
Ubude be-welding liner inempembelelo enkulu kwindlela ucingo oluya kuyondla ngayo yonke indlela. Ukude kakhulu kwe-liner kunokubangela ukuba i-kinking kunye nokutya okungalunganga kocingo, kanti i-liner emfutshane kakhulu ayiyi kubonelela ngenkxaso eyaneleyo yocingo njengoko idlula. Oku kunokukhokelela ekugqibeleni kwi-micro-arcing ngaphakathi kwincam yoqhagamshelwano ebangela ukutshisa okanye ukusilela kwangaphambili. Isenokuba ngunobangela we-arc engaqhelekanga kunye nokufuya iintaka.
Nciphisa i-liner ngokuchanekileyo kwaye usebenzise inkqubo efanelekileyo
Ngelishwa, imiba ye-welding liner trimming ixhaphakile, ngakumbi phakathi kwabaqhubi abanamava kangako. Ukuthatha i- guesswork ngaphandle kokunciphisa i-welding gun liner ngokuchanekileyo - kwaye ufezekise umzila ongenasiphako we-wire-feeding - qwalasela inkqubo ephelisa imfuno yokulinganisa i-liner yokutshintshwa. Esi sixokelelwano sitshixa i-liner endaweni ngasemva kompu, ivumela umqhubi we-welding ukuba ayicuthe ngokugungxula nge-pin yamandla. Esinye isiphelo somgca sitshixa phambi kompu kwincam yoqhagamshelwano; ilungelelaniswe ngokuthe ngqo phakathi kwamanqaku amabini, ngoko ke iliner ayisayi kwandiswa okanye ikhontrakthi ngexesha leentshukumo zesiqhelo.
Inkqubo evala i-liner kwindawo ngasemva kompu kwaye ngaphambili inika indlela yokutya yocingo olugudileyo - yonke indlela entanyeni ukuya kwizinto ezidliwayo kunye ne-weld - njengoko kubonisiwe apha.
Xa usebenzisa i-liner yesiqhelo, kuphephe ukujija umpu xa ucheba iliner kwaye usebenzise igeyiji yokutrima iliner xa kunikezelwa. I-Liners eneprofayili yangaphakathi enikezela ukungqubuzana okuncinci kwi-welding wire njengoko ihamba nge-liner yinto efanelekileyo yokufezekisa ukondla ngocingo olusebenzayo. Ezi zineengubo ezikhethekileyo kuzo kwaye zihlanganiswe ngaphandle kweprofayili enkulu, eyenza i-liner ibe yomelele kwaye inikeze ukutya okugudileyo.
Sebenzisa ingcebiso elungileyo yoqhagamshelwano kwaye uyifake ngokuchanekileyo
Ukutshatisa i-welding ubungakanani bencam yoqhagamshelwano ukuya kububanzi bocingo yenye indlela yokugcina indlela ecacileyo yokutyisa ucingo. Ngokomzekelo, i-0.035-intshi yocingo kufuneka ihambelane ne-tip yoqhagamshelwano efanayo. Kwezinye iimeko, kunokunqweneleka ukunciphisa incam yoqhagamshelwano ngesayizi enye ukuze ufumane ukondla ngocingo olungcono kunye nolawulo lwe-arc. Buza umenzi othembekileyo we-welding consumables okanye umthengisi we-welding kwiingcebiso.
Khangela ukunxitywa ngendlela ye-keyholing (xa i-tip bore yoqhagamshelwano igugile kwaye i-oblong) ekubeni oku kunokubangela ukutshisa okukuthintela ucingo ekutyiseni.
Qinisekisa ukufaka incam yoqhagamshelwano ngokuchanekileyo, uyiqinise ngaphaya komnwe ukuze uphephe ukutshisa ngokugqithiseleyo, okunokuthintela ukondla ngocingo. Qhagamshelana nencwadana yokusebenza evela kumenzi wengcebiso yoqhagamshelwano welding malunga nenkcazo yetorque ecetyiswayo.
Ilinen elungiswe ngokungafanelekanga inokukhokelela ekufuyelweni kweentaka okanye i-tangle yocingo kwi-drive rolls, njengoko kubonisiwe apha.
Khetha iiroli ezifanelekileyo zokuqhuba kwaye usete uxinzelelo ngokufanelekileyo
Imiqulu yokuqhuba idlala indima ebalulekileyo ekuqinisekiseni ukuba umpu we-MIG welding unendlela egudileyo yokutyisa ucingo.
Ubungakanani be-drive roll kufuneka buhambelane nobukhulu bocingo olusetyenziswayo kunye nesitayela sixhomekeke kuhlobo locingo. Xa welding ngocingo oluqinileyo, V-groove drive roll ixhasa ukondla okulungileyo. Iingcingo ze-Flux-cored - zombini i-gas- kunye ne-self-shielded - kunye neengcingo zentsimbi zisebenza kakuhle kunye ne-V-knurled drive rolls. Ukudibanisa i-aluminium, sebenzisa i-U-groove drive rolls; Iingcingo ze-aluminiyam zithambile kakhulu, ngoko ke olu hlobo aluyi kuzityumza okanye zisonakalise.
Ukuseta idrive roll tension, jija iqhosha lefidi yocingo ukuya kwisiqingatha esinye sokujika ukudlula ukutyibilika. Tsala isiqhushumbisi kumpu we-MIG, utyisa ucingo kwisandla seglavu kwaye ngokucothayo ulugobe. Ucingo kufuneka lukwazi ukutya ngaphandle kokutyibilika.
Qonda impembelelo yocingo lwe-welding kwi-feedability
Umgangatho we-welding wire kunye nohlobo lokupakisha kuzo zombini zichaphazela ukondla ucingo. Ucingo olukumgangatho ophezulu luthanda ukuba nedayamitha engaguqukiyo kuneyomgangatho ophantsi, nto leyo eyenza kube lula ukondla kuyo yonke inkqubo. Ikwanayo nesamente engaguqukiyo (i-diameter xa ubude bocingo busikiwe kwi-spool kwaye ibekwe kwindawo ethe tyaba) kunye ne-helix (umgama onyukayo ucingo ukusuka kumphezulu osicaba), okongeza kwi-feedability yocingo.
Ngelixa ucingo olukumgangatho ophezulu lunokubiza ngakumbi ngaphambili, lunokunceda ukunciphisa iindleko zexesha elide ngokunciphisa umngcipheko wemiba yokondla.
Hlola i-tip yoqhagamshelwano ye-keyholing, njengoko inokukhokelela ekutshiseni (ukwenziwa kwe-weld okanye kwi-tip yoqhagamshelwano) njengoko kubonisiwe kulo mzekeliso.
Iingcingo ezisuka kwimigqomo emikhulu zihlala zinesanti enkulu xa zikhutshwa kwipakethe, ngoko ke zikholisa ukondla ngokuthe ngqo kuneengcingo ezisuka kwi-spool. Ukuba umthamo womsebenzi wokuwelda unokuxhasa igubu elikhulu, oku kunokuba yingqwalaselo yazo zombini iinjongo zokutyisa ucingo kunye nokunciphisa ixesha lokutshintsha.
Ukwenza utyalo-mali
Ukongeza kokulandela iindlela ezifanelekileyo zokuseka indlela yokutya ecacileyo yocingo - kunye nokwazi ukukhawuleza ukusombulula iingxaki - ukuba nezixhobo ezithembekileyo kubalulekile. Utyalo-mali lwangaphambili lwesondlo socingo olukumgangatho ophezulu kunye nezinto ezityiwayo ze-welding ezihlala ixesha elide zinokuhlawulela ixesha elide ngokunciphisa imiba kunye neendleko ezinxulumene neengxaki zocingo. Ukunciphisa ixesha elingaphantsi kuthetha ukugxila ngakumbi ekuveliseni iinxalenye kunye nokuzikhupha kubathengi.
