Ukukhetha igesi yokukhusela engalunganga kunokukushiya une-welds egcwele iimbobo, ukuchitheka, okanye amandla abuthathaka—nokuba usebenzisa ucingo oluqinileyo lwe-MIG kunye nezixhobo. Igesi yokukhusela ye-MIG isenokubonakala ingabonakali, kodwa "yifomyula yesitshixo esingabonakaliyo" echaphazela ngokuthe ngqo iimpawu ze-arc, iindlela zokudlulisa isinyithi, kunye neempawu zokugqibela zoomatshini ze-weld. Ngezantsi, siza kuhlalutya isakhelo esilula sesigqibo ukukunceda ukhethe igesi yokukhusela efanelekileyo kwisicelo sakho.
Isakhelo seSigqibo: Fumana iGesi yakho yoKhuseleko egqibeleleyo
Siza kujonga imibuzo emithathu ephambili ukuze sinciphise ukhetho lwakho. Akusekho mfuneko yokuqikelela—kukhetho olujolise kulo olusekelwe kwiimfuno zakho zokwenyani.
Umbuzo 1: Zeziphi izinto oziWeldayo?
Izinto zokwakha zezona zinto zibalulekileyo nezibalulekileyo. Masiqale ngezona ziqhelekileyo size sitshintshele kwiintsimbi ezikhethekileyo.
Intsimbi Ethambileyo (Eyona Imeko Ixhaphakileyo)
Kwigesi yokuwelda intsimbi ethambileyo ngentambo eqinileyo ye-MIG, kukho iindlela ezimbini eziphambili kwimarike. Nantsi indlela ezihlanganiswa ngayo:
Igesi ye-C25 (75% Ar, 25% CO2) – Ukhetho Lokuqala Lwehlabathi
Isizathu sokuba isebenze: Lo mxube we-argon CO2 unika i-arc ezinzileyo, ukuchitheka okuncinci kwe-welding, kunye nembonakalo ye-weld egudileyo—ukusombulula iingxaki ezinkulu ze-welding yentsimbi ethambileyo. Inciphisa ukulahleka kwezinto ze-alloy, yonyusa amandla okuxinana kwe-weld, kwaye isebenza kwiintlobo ezininzi zezicelo, ukusuka kwiishiti ezincinci ukuya kwiiplate ezinobukhulu obuphakathi. Nokuba wenza i-short-circuit okanye i-spray transfer, i-C25 igcina inkqubo icocekile kwaye ilawuleka.C25
Eyona ilungele: Uninzi lwemisebenzi yentsimbi ethambileyo apho umgangatho, inkangeleko, kunye nokulula kokusebenza kubalulekile.
I-CO2 ecocekileyo - Urhwebo olugcina iindleko
Isizathu sokusetyenziswa kwayo: I-CO2 ecocekileyo ixabisa kancinci kuneegesi ezixutyiweyo, nto leyo eyenza ukuba ibe nomtsalane kwimisebenzi emininzi ngebhajethi encinci. Ikwabonelela ngokungena nzulu, okuluncedo kwi-welding yepleyiti etyebileyo ngaphandle kokujika. Utshintshiselwano: Lindela i-arc "enzima", ukuchitheka kwe-welding okuninzi, kunye nomphezulu we-weld orhabaxa. Uza kuchitha ixesha elongezelelweyo ekucoceni emva kwe-weld, kwaye ilahleko ye-alloy iphezulu xa ithelekiswa ne-C25.
Eyona ilungeleyo: Intsimbi ethambileyo neqinileyo apho inkangeleko ingekho nzulu khona kwaye ixabiso liphezulu.
Icebiso lobuchule: Ukuba uthungela intsimbi ethambileyo kwaye ufuna inkqubo ecocekileyo nengenangxaki, qala nge-C25. Lelona khetho lisebenziseka lula kwiindlela zokusebenzisa i-MIG wire eqinileyo.
Yenziwe ngentsimbi eshayinayo
Igesi yokuwelda yentsimbi engagqwaliyo kufuneka igcine ukumelana nokugqwala kwaye iqinisekise ukubonakala kakuhle kokuwelda. I-argon ecocekileyo ayisebenzi apha—ikhokelela ekubeni ukumanzisa okungalunganga kokuwelda kunye nokungcola成形Khetha igesi exutywe kathathu efana ne-Ar + 2-5% CO2 + 1-2% O2 okanye i-Ar + 90% He + 2.5% CO2. Ezi zinto zidibanisa uxinzelelo oluphantsi lomphezulu wesinyithi onyibilikisiweyo, ziphucula ukusasazeka kwe-weld, kwaye zinciphise ukulahleka kwe-alloy, zigcina iipropati zokukhusela zentsimbi engagqwali zingasebenzi.
I-aluminiyam
I-Aluminiyam ifuna i-argon ecocekileyo okanye umxube we-argon-helium. Umsebenzi ophambili we-Argon kukucoca ifilimu ye-aluminium oxide (eyimfuneko kwii-welds eziqinileyo) kunye nokuzinzisa i-arc. Ukongeza i-helium kwandisa ubushushu, okunceda kwiindawo ze-aluminium ezixineneyo ngokwandisa ukungena kunye nesantya sokuwelda. Kuphephe nayiphi na i-CO2 okanye i-O2 kwigesi yokukhusela i-aluminium—ziya kubangela ukubola kunye nee-welds ezibuthathaka.
Umbuzo 2: Zeziphi iiPropati zeWeld ozibeka phambili?
Ukhetho lwakho lwegesi luchaphazela ngqo indlela ebukeka kwaye isebenza ngayo i-weld yakho. Tshatisa igesi kunye neempawu zakho ezibalulekileyo:
- Ngaba ufuna iintsimbi ezibanzi ze-weld kunye nokungena okuncinci (kulungele amaphepha amancinci)? Sebenzisa umlinganiselo ophezulu we-argon - ithambisa i-arc kwaye ithintele ukutsha.
- Ngaba ufuna ukungena nzulu kwiipleyiti ezityebileyo? Umxube we-CO2 omsulwa okanye ophezulu we-CO2 uzisa ubushushu obuqinileyo.
- Ufuna isantya esikhawulezayo sokuwelda? Imixube yeArgon-helium okanye iC25 ivumela i-amperage ephezulu ngaphandle kokuchithachitha kakhulu, nto leyo enyusa imveliso.
- Uyayithiya into yokucocwa emva kokuwelda? I-C25 okanye eminye imixube etyebileyo ye-argon iyanciphisa kakhulu ukuchitheka kwe-welding, nto leyo ekongela ixesha lokusila nokugqiba.
Umbuzo 3: Uhlahlo-lwabiwo mali lwakho lungakanani?
Masisebenziseke—uhlahlo lwabiwo-mali luqhuba izigqibo ezininzi. Nantsi indlela yokwenyani yokwahlulahlula iindleko, ngaphaya kwexabiso lepetroli kuphela:
- I-CO2 ecocekileyo: Ixabiso eliphantsi legesi kwangaphambili, kodwa iindleko eziphezulu zexesha elide ngenxa yexesha elongezelelweyo lokucoca kunye nokwanda kwenkunkuma ye-MIG wire waste.
- Igesi ye-C25: Ixabiso legesi liphezulu kune-CO2 ecocekileyo, kodwa iindleko zizonke ziphantsi ngenxa yesantya esikhawulezayo sokuwelda kunye nokulungiswa okuncinci. Akukho zixhobo zongezelelweyo ezifunekayo—sisilinda esinye sokuxuba.
- Umxube we-tri-mix okanye we-argon-helium: Ixabiso eliphezulu lezinto ezikhethekileyo, kodwa liyimfuneko ukuze kuthintelwe ukusilela kwe-weld ebiza kakhulu.
Nantsi ke le nto ithethwayo: Ukuba unebhajethi encinci kodwa udibanise intsimbi eninzi, i-CO2 ecocekileyo inokwenzeka—ixesha lokucoca lixhomekeke kuphela kwixabiso. Kwiivenkile ezininzi, i-C25 inikezela ngebhalansi engcono kakhulu yeendleko kunye nokusebenza.
Iingcebiso ezibalulekileyo: Musa ukonakalisa ukhetho oluhle lwegesi ngokuseta kakubi
Kwanegesi yokukhusela efanelekileyo ayizukusindisa i-weld yakho ukuba ungcolisa isantya sokuhamba kwegesi okanye ukoma kwegesi. Ezi nkcukacha azinakuxoxiswana ngazo:
Izinga lokuhamba kwegesi (CFH/LPM)
Ukugeleza okuncinci kakhulu kushiya i-weld yakho ingakhuselekanga (kubangela ukugoba kwe-weld); ukugoba kakhulu kudala i-turbulence (ifunxa umoya, ikwabangela ukugoba). Kwiinkqubo ezininzi ze-MIG wire eqinileyo:
- Intsimbi ethambileyo (C25 okanye i-CO2 ecocekileyo): 15-25 LPM (30-50 CFH)
- Intsimbi engatyiwayo (umxube ongama-tri): 18-28 LPM (38-60 CFH)
- I-Aluminiyam (argon/argon-helium): 20-30 LPM (42-63 CFH)
Ukoma kwegesi
Ukufuma kwigesi ekhuselayo kukubulala ngokungathethiyo. Kubangela ukuxinana kwe-weld kwaye kunciphisa ukuxinana. Soloko usebenzisa isixhobo sokomisa/isihluzi kumgca wakho wegesi, kwaye ujonge ukuba iisilinda zakho zingaphezulu kwe-0.5 MPa (70 psi)—ngaphantsi koxinzelelo, ukufuma kunye nokungcola kugxile kwigesi.
Umgaqo Wokugqibela kunye neNyathelo Elilandelayo
Umgaqo ophambili: Tshatisa igesi yakho yokukhusela nezinto zakho, ulinganise umgangatho kunye nexabiso, kwaye soloko uqinisekisa ukuhanjiswa kwegesi okucocekileyo nokwanelisayo. Yenza oku kulungeleyo, kwaye i-solid yakho ilungelelaniswe.Ucingo lwe-MIGiza kusebenza kakuhle kakhulu.
Wakuba ukhethe igesi yokukhusela efanelekileyo, ukukhetha intambo eqinileyo ye-MIG esemgangathweni ophezulu ehambelana negesi kunye nezinto zakho linyathelo elilandelayo lempumelelo yokuwelda. Intambo eqinileyo ye-MIG iqinisekisa ukwakheka kweekhemikhali okuzinzileyo kunye nokondla intambo egudileyo—isebenza ngokuhambelana negesi yokukhusela oyikhethileyo ngononophelo ukuze inikezele nge-welds ezihambelanayo neziqinileyo ngalo lonke ixesha.
