Iingcingo ze-MIG zidlala indima ebalulekileyo ekudibaniseni izinto zanamhlanje. Ukuze sifumane iziphumo zokudibanisela ezikumgangatho ophezulu, kufuneka sazi indlela yokukhetha nokusebenzisa iingcingo ze-MIG ngokuchanekileyo.
Ungayikhetha njani intambo ye-MIG?
Okokuqala, kufuneka sisekelwe kwizinto ezisisiseko, iintlobo ezahlukeneyo zezinto ezisisiseko zimisela icala lokukhethwa kwentambo. Izinto ezisisiseko eziqhelekileyo yintsimbi yekhabhoni, intsimbi engatyiwayo, i-aluminium alloy njalo njalo. Kwintsimbi yekhabhoni, ukhetho lweucingo lokuweldakufuneka isekelwe kwinqanaba layo lamandla. Intsimbi yekhabhoni enamandla aphantsi inokukhetha ucingo oluqhelekileyo lwentsimbi yekhabhoni, ngelixa intsimbi yekhabhoni enamandla aphezulu ifuna ucingo olunamandla aphezulu ukuqinisekisa ukusebenza emva kokuwelda. Kukho iintlobo ezininzi zentsimbi engagqwaliyo, kuquka intsimbi engagqwaliyo ye-austenitic, intsimbi engagqwali ye-ferritic, intsimbi engagqwali ye-martensitic njalo njalo. Uhlobo ngalunye lwentsimbi engagqwaliyo luneempawu zalo zeekhemikhali kunye nokusebenza, ngoko ke kufuneka ukhethe ucingo lwentsimbi engagqwaliyo oluhambelanayo, ukuze kuqinisekiswe ukuba ukumelana nokugqwala kunye neempawu zoomatshini zentsimbi ziyahambelana nezinto eziyintloko.
Kakade ke, iimfuno zokusebenza kwe-welding kunye nathi kwicandelo lokuqwalaselwa, iimfuno zamandla e-weld yenye yezona zinto zibalulekileyo ekukhetheni ucingo. Ukuba i-weld ifuna ukumelana nemithwalo ephezulu, kufuneka kukhethwe ucingo olunamandla aphezulu. Oku kuqinisekisa ukuba i-weld joint ayizukuphuka ngexesha lokusetyenziswa. Kwi-welding eneemfuno zokuxhathisa ukugqwala, ezifana nezixhobo zokusebenza ezisetyenziswa kwiindawo ezinzima ezifana nomzi-mveliso weekhemikhali kunye nolwandle, kuyimfuneko ukukhetha iingcingo ze-welding ezixhathisa ukugqwala. Ukuba i-welded workpiece kufuneka ibe nokuqina okuhle okanye ukusebenza okuphantsi kobushushu, kufuneka ukhethe ngononophelo ucingo olufanelekileyo ukuhlangabezana nezi mfuno zikhethekileyo.
Okwesibini, kufuneka simisele ububanzi bentambo. Ukukhetha ububanzi bentambo kunye nomsinga wokuwelda, indawo yokuwelda kunye nobukhulu bezinto ezisisiseko kunxulumene ngokusondeleyo. Ngokubanzi, umsinga wokuwelda omkhulu kunye nezinto ezisisiseko ezityebileyo kufuna ukusetyenziswa kwentambo etyebileyo. Oku kungenxa yokuba iingcingo ezityebileyo zinokumelana nemisinga ephezulu kwaye zibonelele ngentsimbi engaphezulu yokugcwalisa ukuqinisekisa amandla e-weld. Xa kuthelekiswa ne-welding yepleyiti encinci, iingcingo ezincinci zobubanzi zihlala zikhethwa ukuze kuncitshiswe ubushushu bokuwelda kunye nokuthintela ukutsha kunye nokugqwetheka. Kwiindawo ezahlukeneyo zokuwelda, kuyimfuneko ukukhetha ububanzi obufanelekileyo bentambo yokuwelda. Umzekelo, kwindawo yokuwelda ephezulu, ngenxa yobunzima bokusebenza, ukuze kube lula ukusebenza kunye nokuqinisekisa umgangatho wokuwelda, kufuneka ukhethe intambo etyebileyo.
Ukongeza koku, kufuneka sidibanise iiparameter zenkqubo yokuwelda ekukhetheni ucingo, iiparameter ezahlukeneyo zenkqubo yokuwelda ze-MIG, ezifana nomsinga wokuwelda, i-voltage, isantya sokuwelda, njl.njl., nazo zinempembelelo ebalulekileyo ekukhetheni ucingo. Kufuneka zisekelwe kwiiparameter zenkqubo yokuwelda zokwenyani ukuze ukhethe ucingo olunokuziqhelanisa nezi parameter. Kwimeko yokuwelda komsinga ophezulu kunye nesantya esiphezulu, kubalulekile ukuqinisekisa ukuba ucingo lunokunyibilika ngokulinganayo kwaye lwenze i-weld esemgangathweni ophezulu kwinkqubo yokuwelda ekhawulezayo. Kubalulekile ukukhetha ucingo lokuwelda oluneempawu ezilungileyo zokubeka kunye nozinzo.
Kwangaxeshanye, kufuneka siqwalasele uzinzo lonikezelo lwentambo kunye nenkonzo yasemva kokuthengisa. Khetha uphawu lwentambo olunegama elihle kunye neendlela zokubonelela ezinokuthenjwa ukuqinisekisa ukuba akuyi kubakho ukunqongophala kwentambo kwinkqubo yokudibanisa. I-TANKII Alloy inoluhlu olubanzi lweentambo zokudibanisa ezinomgangatho ozinzileyo, ukuba uyazifuna, nceda unxibelelane nathi.
Ngoko ke zeziphi iindlela zokuthintela ukusetyenziswaUcingo lokuwelda lwe-MIG?
Into yokuqala ekufuneka siyikhankanye kukuba malunga nezixhobo, kubalulekile ukukhetha i-welder efanelekileyo yokudibanisa i-MIG. Ukusebenza kwe-welder kufuneka kuzinzile, kwaye i-output current kunye ne-voltage kufuneka zichaneke. Kwangaxeshanye, qiniseka ukuba i-welder isekelwe kakuhle ukuze kuthintelwe umbane. Ukusebenza okuqhelekileyo kwenkqubo yokondla iingcingo ngundoqo ekuqinisekiseni umgangatho wokudityaniswa. Indlela yokondla iingcingo kufuneka isebenze kakuhle kwaye uxinzelelo lwevili lokondla iingcingo kufuneka lube phakathi ukuze kuthintelwe ukondla iingcingo ezingazinzanga okanye ukutyibilika kwengcingo. Ukongeza, ityhubhu yokondla iingcingo kufuneka icocwe rhoqo ukuze kuthintelwe ukuvaleka.
Ukukhetha igesi ekhuselayo nako kubalulekile. Iigesi ezikhuselayo eziqhelekileyo yi-argon, i-helium okanye umxube wazo. Qiniseka ukuba ubunyulu begesi ekhuselayo buhlangabezana neemfuno zokuqinisekisa umgangatho wokuwelda. Ukulungiswa okufanelekileyo kokuhamba kwegesi ekhuselayo kubaluleke kakhulu. Ngokubanzi, ukuhamba kwegesi kufuneka kulungiswe ngokwe-welding current, ububanzi bentambo kunye nendawo yokuwelda kunye nezinye izinto. Ukongeza, inkqubo yokuwelda, ukuqinisekisa ukhuseleko oluhle lwegesi ejikeleze indawo yokuwelda, ukuthintela ukungena komoya echibini elinyibilikisiweyo.
Kufuneka kuqatshelwe ukuba ngokubanzi sikhetha ucingo olufanelekileyo lwe-MIG ngokwezinto ezisetyenzisiweyo, ubukhulu kunye neemfuno zokuwelda zezinto ezisisiseko. Ububanzi, ukwakheka kweekhemikhali kunye neempawu zoomatshini zocingo lokuwelda kufuneka zihambelane nezinto ezisisiseko. Kufuneka sijonge umgangatho womphezulu wocingo lokuwelda ngaphambi kokuba silusebenzise, kwaye silucoce ukuba kukho ukugqwala kunye neoyile. Lawula ubude bolwandiso locingo lokuwelda. Ngokubanzi, ubude bocingo buphindwe kalishumi kunobubanzi bocingo olufanelekileyo. Ukolula ubude obude kakhulu kuya kukhokelela ekuchaseni okwandisiweyo, ukuze ucingo lugqithise kakhulu, nto leyo echaphazela umgangatho wokuwelda.
Ukongeza, iindawo ezahlukeneyo zokuwelda zineemfuno ezahlukeneyo zenkqubo yokuwelda. Kwindawo yokuwelda ethe tyaba, ukuwelda ngokuthe nkqo, ukuwelda okuthe tye kunye nendawo yokuwelda engasemva, kufuneka kulungiswe iiparameter zokuwelda kunye neendlela zokusebenza ukuqinisekisa umgangatho wokuwelda. Kwindawo yokuwelda kwezinye izinto ezifana neepleyiti ezixineneyo okanye intsimbi enekhabhoni ephezulu, ukufudumeza kwangaphambili kunokufuneka ukuthintela ukuqhekeka. Kwangaxeshanye, ubushushu be-interlayer kufuneka bulawulwe ukuze kuthintelwe ukuphakama kakhulu okanye ukuba sezantsi kakhulu. Ngexesha lenkqubo yokuwelda, i-slag kunye ne-spatter kumphezulu we-weld kufuneka zicocwe ngexesha ukuqinisekisa umgangatho wokubonakala kwe-weld kunye nenkqubela egudileyo yokuwelda okulandelayo.
