Umahluko phakathi kwe-MIG kunye ne-TIG Welding

Iindlela ze-MIG kunye ne-TIG zidibanisa isinyithi ngokusebenzisa i-arc yombane kunye negesi ekhuselayo eyenza i-weld. Nangona zifana ngeendlela ezininzi, zineempawu ezahlulayo. Ekubeni nganye yezi ndlela ineenzuzo zayo kunye neengozi zayo, kubalulekile ukuba nalo lonke ulwazi ngaphambi kokuba wenze isigqibo malunga nokuba yeyiphi na indlela onokusetyenziswa ngayo.

Eli nqaku liza kugxininisa ukungafani okuphambili phakathi kwe-MIG kunye ne-TIG iindlela ze-welding. Ukongeza, iya kuxoxa ngezinto ezilungileyo kunye neengxaki zabo.

Yintoni i-MIG yokuwelda?

Irhasi ye-inert yesinyithi i-welding ikwabizwa ngokuba yi-gas metal arc welding (GMAW). Le nkqubo isebenzisa i-semi-automatic okanye i-arc ngokuzenzekelayo ngokuzenzekelayo ukuvelisa i-weld kunye nempahla yokuzalisa i-electrode yocingo. Ikwasebenzisa irhasi ekhuselayo ukukhusela i-weld, ukwandisa ukungena kwe-weld, kunye nokunciphisa i-weld bead porosity.

Igesi yokukhusela kunye ne-electrode yondliwa nge itotshi yokuwelda okanye umpu. Inhlanganisela yegesi yokukhusela iquka i-75% ye-argon kunye ne-25% ye-carbon dioxide. Eminye imixube ingasetyenziswa ngokuxhomekeke kwizinto ezikwinkqubo ye-welding kunye nezinye izinto eziguquguqukayo ezifana nobukhulu kunye nobukhulu bezinto zokusebenza. Ububanzi be-electrode yocingo oluqhubekayo luyahluka ngokweentlobo zetsimbi ezidityanisiweyo, ukucwangciswa ngokubambisana, kunye nobukhulu benxalenye. I-electrode yondliwa kwi-weld ngesantya esinqunywe yi-wire feed speed (WFS) izicwangciso ukunika i-weld eyaneleyo ukujoyina isinyithi.

Yintoni i-TIG welding?

Irhasi ye-inert yeTungsten ukuwelda ikwabizwa ngokuba yi-gas tungsten arc welding (GTAW). Inkqubo isebenzisa i-arc kunye ne-electrode ye-tungsten engasetyenziswayo kunye nezinto ezihlukeneyo zokuzalisa. Le filler yintonga ethi ifakwe kwi-weld pool; ngaloo ndlela zombini izandla zisetyenziswa, apho enye ibambe i-tungsten kwaye enye, intonga yokuzalisa.

I-weld eyenziwayo inquma ukubunjwa kunye nobukhulu bentonga yokuzalisa. Inkqubo ye-welding ye-TIG isebenzisa igesi yokukhusela eyi-100% ye-argon. Ikharbhon diokside ayisetyenziswa kuba ikhokelela kwi tungsten ukwakheka kweoksidi, enxiba kwangaphambi kwexesha i-electrode kwaye ingcolise i-weld. Le nkqubo ikwadinga i-pedal yonyawo kumqhubi ukulawula i-amperage kunye nokulungelelanisa ubushushu ngexesha le-welding.

Umahluko phakathi kwe-MIG kunye ne-TIG welding

1. Ixabiso

Ukuqwalasela iindleko ngenyawo nganye ye-bead, ukuwelda kwe-TIG kubiza ngaphezu kwe-MIG welding. Kukho amaxabiso aphantsi okubekwa kwezinto kwi-TIG welds efuna abasebenzi abanamava ngakumbi, abaneendleko zokuqesha. Le nkqubo ikwafuna umsebenzi wokulungiselela owongezelelekileyo, nto leyo ephakamisa ixabiso lilonke. Ukongeza, izixhobo ze-MIG zokuwelda kunye nezixhobo zithande ukubiza kancinci kune-TIG. Zonke ezi zinto zibonisa ukuba i-TIG welds zibiza kakhulu xa kuthelekiswa ne-MIG welds.

2. Isantya

Iintsimbi ezipholileyo zeMIG zondla imathiriyeli yesihluzi ngokuzenzekelayo kwi-weld pool kwaye ibe ne-arc ebanzi nengqukuva esusa ngokulula ubushushu. Ngenxa yoko, abaqhubi bahambisa i-weld puddle ngokukhawuleza ngelixa beqhuba ixesha elide ngaphandle kokutshisa.

Kwelinye icala, abashiseli be-TIG abanako ukubonelela ngeentonga zokugcwalisa ezaneleyo zokuphuma kwizantya ze-welding ze-MIG njengoko bengakwazi ukuhambisa i-weld puddle ngokukhawuleza. Kwakhona, iitotshi ezipholileyo zomoya kwi-TIG welding zihlala zishushu kakhulu ngexesha lokuhamba ixesha elide. Ngokuqhelekileyo, kufuneka zipholise okanye zitshintshwe ngexabiso elithe kratya iitotshi zokupholisa ngamanzi.

3. Imathiriyeli esebenzayo

Kukho umahluko omncinci phakathi kwe-TIG kunye ne-MIG xa kuziwa ekukhetheni izinto eziphathekayo. Zombini iindlela ze-arc welding zifanelekile kuluhlu olubanzi lwesinyithi njengentsimbi yekhabhoni, i-aluminiyam, kunye nentsimbi engenasici. Nangona kunjalo, ukuwelda kwe-TIG kusebenza ngcono ngeentsimbi ezibhityileyo, ngelixa ukuwelda kwe-MIG kuzilungele iintsimbi ezishinyeneyo. Ukongezelela, i-TIG welding inikezela ngolawulo olungcono lokusebenza, olunciphisa ukutshatyalaliswa komsebenzi.

4. Amandla e-weld

I-TIG welds yomelele kunezo zenziwe yi-MIG welding. Oku kungenxa yokuba i-TIG welders yenza i-arc emxinwa kwaye igxininise enika ukungena okungcono kwintsimbi. Kwakhona, i-TIG weld beads, ukuba isetyenziswe ngokuchanekileyo, iqulethe imingxuma embalwa kunye nezinye iziphene ezinokuthi zenze buthathaka i-weld.

Nangona kunjalo, i-MIG welds inokudala i-welds eqinile kunye nokungena kakuhle kwesinyithi ngokusika okanye ukugaya i-groove ene-V kwi-joint. Oku kufuneka kwenziwe ngaphambi kokuqala inkqubo ye-welding ukuphucula ukungena. Ukongeza, umthengi unokuthatha ithuba lesantya esihle sokuhamba kunye netotshi ukuphucula amandla e-MIG welds.

5. Ubunzima benkqubo

Inkqubo ye-MIG welding kulula ukuyifunda ngokuchasene ne-TIG welding. Oku kungenxa yokuba ukuwelda kwe-TIG kubandakanya ukusetyenziswa kwezandla ezimbini, apho enye ihambisa itotshi ye-welding kwaye enye ityisa intonga yokuzalisa kwi-weld pool. Ukongeza, kukho i-pedal yeenyawo esetyenziselwa ukulawula i-amperage. Zonke ezi ntshukumo kufuneka zidityaniswe ukuze kuphunyezwe i-weld efunekayo kwaye ke kunokuba nzima ukuyiqonda.

I-TIG yinkqubo ye-welding ehamba phambili njengoko iintsimbi ezidibeneyo kufuneka zicocwe kwaye zilungiswe kakuhle kwinkqubo. Ngokwahlukileyo, i-MIG welding kulula ukuyiqonda. Akukho nyawo olunyathelayo lokulawula kwaye izinto zokuzalisa zondliwa ngokuzenzekelayo kwi-welding gun, efuna isandla esinye kuphela ukudala i-weld.

6. I-Electrode

The umbane esetyenziswa nokuba yi-MIG okanye kwi-TIG yohluka. Inkqubo ye-MIG ye-welding isebenzisa i-electrode yocingo esetyenziswayo ngokuqhubekayo xa idibanisa iziqwenga ezimbini zetsimbi. I-TIG, ngakolunye uhlangothi, isebenzisa i-electrode ye-tungsten engasetyenziswayo kunye nentsimbi eyahlukileyo yokuzalisa. Ngenxa yoko, abathengi baya kusebenzisa isandla esinye ukwenza i-MIG ye-welding ngokuchasene ne-TIG, i-welding apho kufuneka babe nesandla esinye kwi-torch kunye nesinye kwi-filler material.

7. Umthombo wamandla

Kwi-MIG welding, umthombo othe ngqo (DC) usetyenziselwa ukudala uzinzo kwi-arc yombane. Amandla nawo anika ukungena okwaneleyo kweentsimbi. Ngokwahlukileyo, i-TIG ye-welding inikezela ngeendlela ezahlukeneyo njengoko inokutsala amandla ukusuka kwimithombo yombane etshintshanayo (AC) kunye ne-direct current (DC) yamandla. Nangona kunjalo, ukhetho lwamandla luxhomekeke kwi zesinyithi ukuwelda, inani lokutshiza kwi-weld pool, kunye ne-arc yombane efunekayo.

8. Weld aesthetics

Iiweldi ze-TIG zibonisa iimpawu ezingcono zobuhle xa kuthelekiswa ne-MIG welds. I-TIG welds ine-spatter encinci okanye ayinayo into efuna kuphela ukugulisa ukukhanya ukugqiba kunye nokususa umbala. Umzekelo, iinkozo ze-TIG ezidityanisiweyo zenziwa eyona weld ithandeka kakhulu kwaye ingasetyenziselwa ukwenza iiweld ezingapeyintwanga zibukeke ngcono.

Ngokwahlukileyo, i-MIG welds ayinqweneleki kangako ngenkangeleko. Ifuna abachwephesha abanamava ukwenza amaso e-MIG akhangeleka kakuhle. I-MIG welds ilungile kwizicelo apho inkangeleko ingathathwa njengento ebalulekileyo. Ukongezelela, i-aesthetics ayidingeki apho i-welds kufuneka ifakwe ukuze igubungele inkangeleko yokudibanisa.

isiphelo

Ngokucacileyo, zombini i-MIG kunye ne-TIG inokuthathwa ibhetele kunomnye njengoko zombini iinkqubo ze-welding zineenzuzo kunye nokungonakali ngokusekelwe kwimeko yesicelo. I-MIG ilula ngokubanzi ukuyifunda kwaye ikhawuleza ngelixa i-TIG ithathwa njengokuvelisa iiwelds ezikumgangatho ophezulu. Nangona kunjalo, zombini iimeko zinokuba nezinto ezikhethekileyo kwaye ukhetho lomthengi luxhomekeke kwimisebenzi eyenziwayo. Abathengi kufuneka babe neeprojekthi engqondweni kwaye baqwalasele izinto ezininzi ezifana neendleko, uhlobo lwempahla, izixhobo, kunye neemfuno zasemva kokulungiswa ukwenza ukhetho lwe-welding olunolwazi.
