Oomatshini bokuwelda be-MIG: Isabelo semarike kunye nemfuno
Imakethi yewelding yehlabathi kulindeleke ukuba ikhule ngesantya esidibeneyo sokukhula ngonyaka (CAGR) ngaphezulu kwe-4.6% ngo-2028. Imakethi yewelding yehlabathi idlule i-US $20 yeebhiliyoni ngo-2020, ikhetha uqikelelo lweCAGR. Nangona kunjalo, ngelixa imfuno yehlabathi jikelele yomgangatho womatshini wokuwelda isonyuka, amashishini athile ajongene nokunqongophala kwe-welder.
Ngokutsho kwe-American Welding Society (AWS), ilizwe lilindele ukuba a Intsilelo ye-375,000 yezakhono zokuwelda ngo-2023. Ukunqongophala, nangona kunjalo, kwandisa imfuno yomgangatho ophezulu kunye noomatshini bokuwelda beteknoloji, abafana noomatshini bokuwelda be-MIG.
Izinto ezi-5 ekufuneka ziqwalaselwe xa kuthengwa oomatshini bokuwelda be-MIG
Uhlobo lwezinto ezinokuthi zifakwe kwi-welded yindawo yokuqala xa ukhetha i-MIG umatshini wokuwelda. Okwangoku kukho iindidi ezininzi zoomatshini bokuwelda be-MIG kwimarike, nganye iyilelwe usetyenziso oluthile lwe-welding kunye nemathiriyeli. Isixhobo simisela amandla afunekayo, ukuphatheka, kunye nomthamo womatshini.
Ngezantsi sixoxa ngezona zinto zibalulekileyo ekufuneka ziqwalaselwe xa ukhetha umatshini we-welding we-MIG.
1. Izinto zokuweld
Ubukhulu bentsimbi edityanisiweyo bumisela uhlobo lomatshini wokuwelda we-MIG oza kusetyenziswa. I-Welders ihlelwe ngokukhoyo ngoku abayivelisayo ngexesha lomjikelo womsebenzi onikiweyo. Umjikelo womsebenzi ubhekisela kubude bexesha umatshini we-welding unokusebenzisa i-amperage ethile ngaphandle kokushisa ngaphakathi kwemizuzu eyi-10. Oomatshini bokuwelda be-MIG abanomjikelo ophezulu womsebenzi balungele ukusetyenzwa kweentsimbi ezishinyeneyo, ngelixa imijikelo yemisebenzi ephantsi ifanelekile kwiintsimbi ezibhityileyo.
2. Isantya seWelding
Isantya se-welding simisela umgangatho we-weld kunye nokusebenza kakuhle kwenkqubo ye-welding. Ngelixa ukuwelda ngesantya esikhawulezayo kunciphisa ixesha le-welding, kunokubangela i-weld ekumgangatho ophantsi ngenxa yokudityaniswa okungaphelelanga kunye nokutshiza okugqithisileyo.
Iiwelder ezili-110 ze-Volt MIG lukhetho olulungileyo kubashicileli abangabaziyo okanye iiprojekthi zasekhaya ze-DIY. Ezi welders ze-MIG zinomjikelezo ophantsi womsebenzi kwaye zilinganiswe ubuninzi be-80-100 amps. Ngenxa yoko, zifanelekile kuphela ukuwelda iintsimbi ezincinci ixesha elifutshane.
I-220 Volt MIG welders, kwelinye icala, ilungele iingcali kunye neeprojekthi ezinkulu. Oomatshini be-220V baneziphumo ezivela kwi-20-220 amps. Ziyakwazi ukuwelda ukuya kutsho kwi-½ ye-intshi yepleyiti kwaye zinokujikwa ukuze zidibanise iintsimbi ezibhityileyo nazo.
Isantya esiphezulu se-welding sinokuchaphazela imveliso kunye nokusebenza kakuhle kwenkqubo ye-welding. Izantya eziphezulu ze-welding zifanelekile ngokubanzi apho imveliso iphambili. Nangona kunjalo, apho ukubonakala kunye namandla kubaluleke kakhulu, isantya esisezantsi se-welding siya kufaneleka ngakumbi.
3. Ukunikezwa amandla
Kukho iindidi ezimbini eziphambili zobonelelo lwamandla e-MIG, ezizezi, ii-inverters kunye neziguquli. Iinguqu zalawula imarike phantse iminyaka eyi-100, ngelixa ii-inverters zithathwa njengesisombululo sale mihla.
Ii-inverters zikhuthaza i-welds ezingcono, ngelixa ii-transformers zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Ii-inverters zidlula ii-transformers kwindawo enye ebalulekileyo - zinciphisa i-weld spatter. Ii-inverters zilungelelanisa ngokuzenzekelayo izinto eziguquguqukayo ezingenakuhlala ziphendula ngokukhawuleza. Uhlengahlengiso oluzenzekelayo lunciphisa amathuba okuba kwenzeke i-weld spatter.
Abaguquli, nangona kunjalo, bagcina inzuzo enye ngaphezulu kwee-inverters - ubomi obude. Ngenxa yoyilo lwabo olulula, banokumelana nemingeni eza kusetyenziso lwemihla ngemihla. Abaguquli baye bahlala ixesha elide kunee-inverters, eziye zavumela abavelisi ukuba bahlalutye ubomi babo kwaye bakhuthaze ukuqina kwabo.
Unikezelo lwamandla olufunekayo luya kuxhomekeka kwizinto kunye nemveliso edityanisiweyo. Nangona kunjalo, njengomgaqo wesithupha, i-MIG welder ye-wire feed kufuneka imiselwe kwisantya ukuya kuluhlu lwama-240 ukuya kuma-intshi angama-290 ngomzuzu (ipm). Isantya sokuhamba kufuneka simiselwe kwi-14 kunye ne-19 ipm, kuxhomekeke kubukhulu bezinto eziphathekayo kunye nohlobo kunye nobukhulu bocingo olusetyenziswayo.
4. Iintlobo zolawulo
Kukho iintlobo ezintathu zolawulo lwe-MIG lwe-welding: i-manual, i-semi-automatic, kunye ne-automatic ngokupheleleyo. Ulawulo lwezandla lunikezela ngeyona siphumo sincinci se-welding, kodwa kulula ukuyisebenzisa kwaye ayibizi. Olu hlobo lolawulo lufaneleke kakhulu kubadibanisi abanamava njengoko benolwazi oluthe kratya malunga neeparamitha ze-welding, i-voltage, kunye ne-welding materials.
Ulawulo lweSemi-automatic luyaziwa ngokulula kunye nokuchaneka njengoko lubonelela ngezantya zengcingo zocingo. Ii-welders zinokuseta iiparamitha ze-welding ngesandla.
Ulawulo oluzenzekelayo oluzenzekelayo lubonelela nge-welds ezichanekileyo nezingaguquguqukiyo kulawulo oluthathu. Bafuna ukuseta ngakumbi kunye nenkqubo kwaye zibiza kakhulu. Ulawulo oluzenzekelayo ngokuzeleyo ludla ngokusetyenziswa kwiindawo zoshishino apho imveliso ephezulu kunye nomgangatho ubalulekile.
5. Amandla e-weld
Amandla e-weld achaphazela ukusebenza kunye nokhuseleko lwemveliso egqityiweyo. Kukho izinto ezininzi ezichaphazela amandla e-weld kunye ne-MIG welder ekhethiweyo. Eyona nto ibalulekileyo luhlobo locingo olusetyenziswayo kunye nesantya sokutya kweengcingo.
Izantya ezisezantsi ze-weld zibangela amaso e-weld acutheneyo kunye nezantya ezicothayo ze-welding, nto leyo evelisa amandla aphezulu e-weld kunye ne-weld ebukekayo. Ngokuchaseneyo, isantya esiphezulu sokutya socingo sikhokelela kumaso e-weld abanzi kunye nezantya ezikhawulezayo ze-welding ezinokukhokelela kumandla asezantsi e-weld kunye ne-weld engabonakaliyo engabonakaliyo.
Iindidi ezahlukeneyo ze-MIG welders
I-MIG welders luhlobo oluqhelekileyo lokuwelda ngentonga evelisa i-welds ezikumgangatho ophezulu kunye nomgudu omncinci. Isebenzisa iimpembelelo zombane ezisuka kumthombo wamandla ukudibanisa amaqhekeza esinyithi kunye kunye ne-electrode yocingo oluluqilima oluyintsimbi kwaye yenze ijoyinti yeweld.
Ukutyhubela iminyaka, imigaqo ye-MIG ye-welding iye yahlala ingatshintshi, kodwa iindlela ezintsha zomthombo wamandla ziye zaziswa kwiimarike ezivumela ukuwelda okusebenzayo ngakumbi.
Ukuqhubela phambili kwimithombo yamandla kuye kwazisa iintlobo ezintsha ze-MIG welders nganye ibonelela ngeempawu ezizodwa, iinzuzo, kunye nokungalunganga.
I-Flux cored arc welders (FCAW)
oomatshini beFCAW zezona zixhaphakileyo kulwakhiwo, kulwakhiwo lweenqanawa, nakumashishini eemoto, nalapho kufuneka iiwelds eziqinileyo nezizinzileyo. Bayakwazi ukuwelda iintlobo ngeentlobo zesinyithi, kuquka intsimbi, intsimbi engatyiwa, kunye nealuminium.
I-FCAW welders ngokubanzi ibandakanya umbane, umpu we-welding, kunye nenkqubo yokutya yocingo.
