Iingcingo ze-MIG zidlala indima ebalulekileyo kwi-welding yanamhlanje. Ukuze sifezekise iziphumo ze-welding ezikumgangatho ophezulu, kufuneka sazi indlela yokukhetha nokusebenzisa iingcingo zeMIG ngokuchanekileyo.
Ungakhetha njani ucingo lweMIG?
Okokuqala, kufuneka sisekelwe kwizinto ezisisiseko, iintlobo ezahlukeneyo zezinto ezisisiseko zinquma indlela yokukhetha ucingo. Izinto ezisisiseko eziqhelekileyo ziyi-carbon steel, insimbi engenasici, i-aluminium alloy kunye nokunye. Kwintsimbi yekhabhoni, ukhetho lweucingo weldingkufuneka isekelwe kwinqanaba amandla ayo. Amandla asezantsi entsimbi yekhabhoni angakhetha i-carbon steel welding wire, ngelixa i-high-high-high carbon steel idinga ucingo lwamandla aphezulu ukuqinisekisa ukusebenza emva kwe-welding. Kukho iintlobo ezininzi zentsimbi, kuquka i-austenitic stainless steel, i-ferritic stainless steel, i-martensitic stainless steel njalo njalo. Ibakala ngalinye lensimbi engenasici linemichiza yalo ekhethekileyo kunye neempawu zokusebenza, ngoko ke kufuneka ukhethe ucingo lwensimbi engenasici ukuze utshatise, ukuze uqinisekise ukuba ukuxhathisa kwe-corrosion kunye neempawu zoomatshini ze-weld ziyahambelana nezinto zomzali.
Ngokuqinisekileyo, iimfuno zokusebenza kwe-welding kunye nathi kububanzi bokuqwalasela, iimfuno zamandla e-weld yenye yesiseko esibalulekileyo sokukhetha ucingo. Ukuba i-weld idinga ukumelana nemithwalo ephezulu, ngoko ke ucingo oluphezulu kufuneka lukhethwe. Oku kuqinisekisa ukuba i-welded joint ayiyi kuphuka ngexesha lokusetyenziswa. Ukuwelda ngeemfuno zokuxhathisa umhlwa, njengezinto zokusebenza ezisetyenziswa kwiindawo ezirhabaxa ezifana neshishini lemichiza kunye nolwandle, kuyafuneka ukuba ukhethe iingcingo ze-welding ezinokumelana nokugqwala okuhambelanayo. Ukuba i-workpiece edibeneyo kufuneka ibe nokuqina okulungileyo okanye ukusebenza okuphantsi kweqondo lokushisa, kufuneka kwakhona ukhethe ngokucophelela ucingo olufanelekileyo ukuhlangabezana nezi mfuno ezizodwa.
Okwesibini, kufuneka sijonge i-diameter yocingo. Ukhetho lwe-wire diameter kunye ne-welding yangoku, indawo ye-welding kunye nesiseko sezinto eziphathekayo zihambelana ngokusondeleyo. Ngokubanzi, i-welding enkulu yangoku kunye nesiseko semathiriyeli engqindilili ifuna ukusetyenziswa kocingo olutyebileyo. Oku kungenxa yokuba iingcingo ezishinyeneyo ziyakwazi ukumelana nemisinga ephezulu kwaye zikwabonelela ngentsimbi ethe kratya yokuzalisa ukuqinisekisa ukomelela kweweld. Xa kuthelekiswa ne-welding plate ebhityileyo, iingcingo ezincinci ze-diameter zivame ukukhethwa ukuze kuncitshiswe igalelo lobushushu be-welding kwaye kuthintelwe ukutshisa kunye nokuphazamiseka. Kwiindawo ezahlukeneyo ze-welding, kuyafuneka ukuba ukhethe ububanzi obufanelekileyo be-welding wire. Ngokomzekelo, kwindawo ye-welding ephezulu, ngenxa yobunzima bokusebenza, ukwenzela ukuba kube lula ukusebenza kunye nokuqinisekisa umgangatho we-welding, kufuneka ukhethe ucingo oluncinci.
Ukongeza koku, kufuneka sidibanise iiparitha zenkqubo ye-welding ekukhetheni ucingo, iiparitha ezahlukeneyo ze-MIG ze-welding, ezifana ne-welding current, i-voltage, isantya se-welding, njl., Kwakhona kunempembelelo ebalulekileyo ekukhethweni kocingo. Kufuneka kusekelwe kwiiparameters zenkqubo ye-welding yokwenene ukukhetha ucingo lunokuziqhelanisa nale parameters. Kwimeko ye-welding ephezulu yangoku kunye nesantya esiphezulu, kubalulekile ukuqinisekisa ukuba ucingo lunokuncibilika ngokufanayo kwaye lwenza i-weld esemgangathweni ophezulu kwinkqubo ye-welding ephezulu. Kuyimfuneko ukuba ukhethe ucingo lwe-welding kunye neempawu ezintle zokubeka kunye nokuzinza.
Kwangaxeshanye, kufuneka siqwalasele uzinzo lonikezelo lwengcingo kunye nenkonzo emva kokuthengisa. Khetha uphawu locingo olunodumo oluhle kunye neendlela ezithembekileyo zokubonelela ukuqinisekisa ukuba akuyi kubakho ukunqongophala kocingo kwinkqubo ye-welding. I-TANKII Alloy inoluhlu olubanzi lweengcingo ze-welding ezinomgangatho ozinzile, ukuba uyayifuna, nceda uqhagamshelane nathi.
Emva koko zeziphi izilumkiso zokusetyenziswaI-MIG yocingo lwe-welding?
Into yokuqala ukuyikhankanya kukuba ngokwezixhobo, kubalulekile ukukhetha i-welder efanelekileyo kwi-MIG. Ukusebenza kwe-welder kufuneka kuzinzile, kwaye imveliso yangoku kunye ne-voltage kufuneka ichaneke. Kwangaxeshanye, qiniseka ukuba i-welder ibekwe kakuhle ukuthintela umbane. Ukusebenza okuqhelekileyo kwenkqubo yokutya yocingo ngundoqo ekuqinisekiseni umgangatho we-welding. Indlela yokuxheshisela ngocingo kufuneka ihambe kakuhle kwaye noxinzelelo lwevili locingo lokuxheshisela kufuneka lubephakathi ukunqanda ukutyibilika kocingo okungazinzanga okanye ukutyibilika kocingo. Ukongezelela, ityhubhu yokutya yocingo kufuneka ihlambuluke rhoqo ukukhusela ukuvala.
Ukukhethwa kwegesi yokukhusela kubalulekile. Iigesi eziqhelekileyo zokukhusela ziyi-argon, i-helium okanye umxube wabo. Qinisekisa ukuba ukucoceka kwegesi yokukhusela ihlangabezana neemfuno zokuqinisekisa umgangatho we-welding. Ukulungelelaniswa okufanelekileyo kokuhamba kwegesi yokukhusela kubaluleke kakhulu. Ngokuqhelekileyo, ukuhamba kwegesi kufuneka kulungiswe ngokuhambelana ne-welding yangoku, i-wire diameter kunye ne-welding position kunye nezinye izinto. Ukongeza inkqubo yokuwelda, ukuqinisekisa ukukhuselwa kakuhle kwegesi ejikeleze indawo ye-welding, ukuphepha ukungena komoya kwi-pool etyhidiweyo.
Kufuneka kuqatshelwe ukuba ngokuqhelekileyo sikhetha ucingo lwe-MIG olufanelekileyo ngokwezinto eziphathekayo, ubukhulu kunye neemfuno ze-welding yezinto ezisisiseko. Ububanzi, ukubunjwa kweekhemikhali kunye neempawu zemishini yocingo lwe-welding kufuneka luhambelane nesiseko sezinto. Kufuneka sihlolisise umgangatho womphezulu wocingo lwe-welding ngaphambi kokusetyenziswa, kwaye sicoce ukuba kukho ukubola kunye neoli. Lawula ubude bokwandiswa kocingo lwe-welding. Ngokuqhelekileyo, ubude bocingo bumalunga namaxesha angama-10 ububanzi bocingo olufanelekileyo. Ukolula ubude obude kakhulu kuya kukhokelela ekuxhathiseni okwandisiweyo, ukwenzela ukuba i-wire overheating, echaphazela umgangatho we-welding.
Ukongezelela, izikhundla ze-welding ezahlukeneyo zineemfuno ezahlukeneyo zenkqubo ye-welding. Kwi-welding flat, i-welding ethe nkqo, i-welding ethe tyaba kunye ne-back welding position, kufuneka ilungelelanise iiparitha ze-welding kunye neendlela zokusebenza zokuqinisekisa umgangatho we-welding. Ukuwelda kwezinye izinto ezifana neepleyiti ezishinyeneyo okanye intsimbi ephezulu yekhabhoni, ukufudumeza kwangaphambili kungafuneka ukuthintela ukuqhekeka. Ngexesha elifanayo, ukushisa kwe-interlayer kufuneka kulawulwe ukuze kugwenywe phezulu okanye kuphantsi kakhulu. Ngethuba lenkqubo ye-welding, i-slag kunye ne-spatter ebusweni be-weld kufuneka ihlambuluke ngexesha lokuqinisekisa ukubonakala komgangatho we-weld kunye nenkqubela phambili ehamba phambili ye-welding elandelayo.
