I-TIG welders, ebizwa ngokuba yi-tungsten inert welders yegesi, sebenzisa i-electrodes ye-tungsten engasetyenziswayo ukuvelisa i-weld kwintsimbi. Ezi welder ziguquguquka njengoko zifanele ukuwelda iintlobo ngeentlobo zesinyithi, kubandakanywa i-aluminiyam, ubhedu, ubhedu, i-magnesium, insimbi engenasici, kunye negolide, phakathi kwezinye isinyithi. Ekubeni i-TIG welders ixhaphake, aba matshini bafumaneka ngokulula.
Ukwazi ukuba yeyiphi phakathi kokhetho olufanelekileyo kwizicelo ezahlukeneyo ze-welding kunokuba ngumngeni. Ke ngoko, eli nqaku liza kuphonononga izinto ezibalulekileyo ekufuneka uziqwalasele ngelixa ukhetha i-TIG welder. Iza kujonga kwakhona kwiindidi ezahlukeneyo ze-TIG welders ezikhoyo ukunceda abathengi ekufumaneni oko kuhambelana neemfuno zabo.

Isishwankathelo semarike yehlabathi ye-TIG welders
Imarike ye-TIG ye-welding yehlabathi ifanelekile I-US $ 13 yezigidigidi kwaye kuqikelelwa ukuba iya kufikelela kwi-25 yeebhiliyoni zeedola zaseMelika ngo-2032, ikhula ngesantya sokukhula sonyaka esihlanganisiweyo (CAGR) se-6.7%. Ukukhula kwentengiso kuphenjelelwa yimfuno yoomatshini bokuwelda abavela kumacandelo ahlukeneyo amashishini, kubandakanya izithuthi, i-aerospace, inqanawa, kunye ne-oyile kunye negesi yegesi.
Isidingo somthengi sokuwelda iintsimbi ezingaqhelekanga ezinobunzima obahlukeneyo zikhokelele ekukhuleni kobungakanani bemakethi ye-TIG welders. Kuba bavelisa ukuwelda okuchanekileyo kunye nomgangatho, abaninzi bakhetha ukuwelda kwegesi ye-tungsten engasebenziyo kunoomatshini bokuwelda ngentonga.
Iingcebiso zokukhetha abashiseli be-TIG
Inqanaba le-amperage
Xa uthenga TIG welder, qwalasela inqanaba le-amperage. Ngamandla ombane ovela kumatshini we-welding olinganiswa ngama-ampere. Oomatshini abanamanqanaba asezantsi e-amperage banika uzinzo olululo lwe-arc lokuqalisa nokugqiba iiwelds.
Iiweldi ze-TIG ezinomlinganiselo ophantsi zilungele iintsimbi ezibhityileyo kuba zinokuvelisa iiweldi ezomeleleyo ngaphandle kokuzitshisa. Kwelinye icala, i-welders yenqanaba eliphezulu le-amperage ifanelekile kwiingcali ezisebenza ngeentsimbi ezishinyeneyo.
I-AC kunye ne-DC welding
Ngaphambi kokutyala imali kwi-TIG welder, kubalulekile ukuqwalasela iinketho zayo zangoku. Iiwelder ezikhoyo zibonelela ngenketho ye-DC okanye enye ye-DC/AC. Olu khetho luxhomekeke kuhlobo lwesinyithi olunokuthi ludibanise ngokufanelekileyo.
Umzekelo, ukuwelda kwe-DC TIG kufanelekile xa udiza iintsimbi eziqhelekileyo njengentsimbi. Xa usebenza ekukhanyeni kunye neentsimbi ezinzima njenge-aluminium, a DC/AC umatshini ihambelana nenjongo ngokufanelekileyo.
Ulawulo oluchanekileyo
Ukujonga ulawulo lwe-welder kubalulekile ngelixa uthengela i-TIG welder ethembekileyo. Aba matshini bayilwe nge-pedal yonyawo enceda ukulungelelanisa inqanaba le-amperage. Kuba lula ukulawula ukuchaneka kwe-welding kunye nomgangatho wokugqibela ngokulawula inqanaba le-amperage.
Ngoko ke, abathengi kufuneka bahlole ulawulo kwaye baqinisekise ukuba luqinile kwaye lukhuselekile kunye nomatshini. Ukuhlola i-welder ngokuchanekileyo kuthintela ukonakalisa i-weld xa ucofa ulawulo olungalunganga. Ukujonga iinkcukacha ezibalulekileyo ezifana nolawulo oluluqilima noluchanekileyo luqinisekisa inkqubo ye-welding egudileyo ngaphandle kokuthomalalisa umgangatho wesiphumo sokugqibela.
Ukusebenza kwe-welding ephantsi
Ukujonga ukusebenza kwe-welder kwi-amperage ephantsi kubalulekile ngaphambi kokuthenga. Oomatshini abane-amperage ephantsi banokunika eyona arcs ezinzile. Kwakhona, banikezela ngesiqalo esilula se-weld, ulawulo olungcono lomgangatho we-weld, kunye nomthamo ogqwesileyo wokuzalisa icrater.
Iiwelder ezisezantsi zithembekile xa usebenza kwiintsimbi ezincinci. Ngokwahlukileyo, i-welders ephezulu ye-amperage isebenza kakubi kwiintsimbi ezincinci. Bavelisa ii-arcs ze-weld ezinamandla ezinokuvutha kunye nokonakalisa isinyithi.
Ukuzinza kwe-arc kwi-amperage ephantsi kuyafuneka ukuze kugqitywe i-weld. Ngokomzekelo, i-concave enkulu inokwakheka xa iwelding i-aluminium, enokuthi iqhekeke emva kokuba i-weld ipholile. I-low amperage welding yenza i-concave encinci ukunciphisa amathuba okuqhekeka xa i-welding iphola.
I-Plasma cutter kunye nezinketho ze-welding stick
Abathengi kufuneka bacinge ngokujonga i-tungsten inert welder yegesi eneempawu ezongezelelweyo. Ukuba neempawu ezongezelelweyo kwi-welder ivumela ukufezekiswa kwemisebenzi emininzi kumatshini omnye. Ngokomzekelo, a umatshini wokuwelda ebonelela ngeplasma yokusika kunye neempawu zokuwelda intonga yenza ukuba isinyithi sisebenze umsebenzi ongenamthungo.
I-TIG welder inokusebenzisa i-electrode ye-tungsten ukubonelela zombini izibonelelo zokusika i-plasma kunye nokudibanisa iziqwenga zetsimbi ezisikiweyo kunye. Umtshini wentonga uba yenye ye-TIG welding ukuba kukho i-backup option. Ukongeza, ukuba ne-a welder esebenza ngeendlela ezininzi igcina kwiindleko zokuthenga oomatshini abahlukeneyo kunye namandla ewonke abanokuwasebenzisa ngokupheleleyo.
amandla
Kubalulekile ukuqwalasela ubungakanani bamandla afunekayo ukuze i-welder isebenze. Kuxhomekeke kuhlobo lwentsimbi oludityanisiweyo. Ngokomzekelo, i-aluminiyam, i-magnesium, kunye ne-alloys ezininzi zetsimbi zisebenzisa i-welders ezinamandla aphezulu. Intsimbi ethambileyo kunye nentsimbi engenasici ifuna ukusebenzisa oomatshini bokuwelda bamandla asezantsi.
Umthamo wamandla onokukhetha nawo uxhomekeke kubungakanani bevenkile. Iivenkile ezincinci ezenza i-welding encinci zinokufuna ukusebenzisa i-welder esebenzisa amandla aphantsi. Iivenkile ezinkulu ze-welding zingakhetha umatshini osebenzisa amandla aphezulu.
Ubukhulu bentsimbi bukwamisela ukuba ngowuphi umatshini wokuwelda oza kuwufumana. Kwiintsimbi ezishinyeneyo, i-TIG welder enamandla kakhulu ifanelekile. Iintsimbi ezibhityileyo zilungile ukusebenza ngoomatshini abasebenzisa amandla amancinci.
