1. Isishwankathelo seeTekhnoloji zokuWelding

TIG Welding

I-TIG welding yinkqubo esebenzisa i-electrode ye-tungsten engasetyenziswayo ukuvelisa i-arc enyibilikisa i-workpieces kunye nentonga yokuzalisa. I-pool ye-weld ikhuselwe ekungcoleni yigesi ye-inert, ngokuqhelekileyo i-argon okanye i-helium. Le ndlela iyaziwa ngokuchaneka kwayo kunye nokukwazi ukuvelisa i-welds ezikumgangatho ophezulu, ngakumbi kwizinto ezincinci.

MIG Welding

Ukuwelda kwe-MIG, kwelinye icala, isebenzisa i-electrode yocingo esetyenziswayo ngokuqhubekayo kunye negesi engasebenziyo yokukhusela. Inkqubo ibonakaliswe ngesantya kunye nokusebenza kakuhle, okwenza ukuba ifaneleke kwimveliso ephezulu. I-MIG welding ihlala ikhethwa kwizinto ezityebileyo ngenxa yamazinga aphezulu okubekwa.

2. Izinto eziluncedo ze-TIG Welding

Ukuchaneka kunye noLawulo

Enye yeenzuzo eziphambili ze-TIG welding kukuchaneka kwayo okungaqhelekanga. Umshiseli unolawulo oluthe kratya kwigalelo lobushushu, nto leyo ibalulekileyo xa welding tungsten carbide. Oku kubaluleke ngakumbi kuba ubushushu obugqithisileyo bunokukhokelela kwi-carbide coarsening, echaphazela kakubi ubunzima kunye nokunganyangeki.

Indawo echatshazelwe bubushushu obuncinane (HAZ)

I-TIG welding ivelisa i-HAZ encinci xa kuthelekiswa ne-MIG welding. Oku kuncitshisiwe kwe-HAZ kunenzuzo xa usebenza ne-tungsten carbide, njengoko inciphisa umngcipheko wokuguqula i-microstructure ye-carbide kunye neempawu.

Ukuguquguquka

Ukuwelda kwe-TIG kuninzi kakhulu kwaye kunokusetyenziswa kuluhlu olubanzi lwezixhobo, kubandakanya isinyithi esingafaniyo. Oku kuguquguquka kunenzuzo kwizicelo apho iingcebiso ze-tungsten carbide kufuneka zifakwe kwii-substrates ezahlukeneyo, ezifana nentsimbi ephezulu okanye insimbi yesixhobo.

3. Izinto eziluncedo kwi-MIG Welding

Isantya kunye nokusebenza kakuhle

Ukuwelda kwe-MIG kudla ngokukhawuleza kune-TIG ye-welding ngenxa yendlela yayo yocingo eqhubekayo. Oku kusebenza kakuhle kuyenza ilungele indawo enkulu yemveliso apho ixesha liyinto ebalulekileyo. Ukukwazi ukukhawuleza ukudibanisa iingcebiso ezininzi kunokuphucula kakhulu imveliso.

Ukusebenziseka lula

Ukuwelda kwe-MIG kuhlala kubonwa kulula ukuyifunda nokusebenza kune-TIG welding. Inkqubo ifuna isakhono esincinci, isenza ukuba ifikeleleke kubasebenzisi abanamanqanaba ahlukeneyo amava. Oku kulula ukusetyenziswa kunokunciphisa iindleko zoqeqesho kunye nokuphucula ukusebenza kakuhle komsebenzi.

Iindleko-Ukusebenza

Ngenxa yamazinga aphezulu okubekwa kunye nezantya ezikhawulezayo zokuwelda, ukuwelda kwe-MIG kunokuba neendleko ezisebenzayo kwizicelo ezithile. Oku kuyinyani ngokukodwa kwiimeko apho kufuneka umthamo ophezulu wemveliso, njengoko ixesha elipheleleyo kunye neendleko zabasebenzi zinokuncitshiswa kakhulu.

4. Iingqwalasela eziphambili

Ulawulo lobushushu

Ngelixa i-TIG i-welding inikezela ngolawulo oluphezulu kwigalelo lobushushu, ifuna umqhubi onobuchule ukulawula inkqubo ngokufanelekileyo. Ngakolunye uhlangothi, i-MIG welding inokwazisa ubushushu obuninzi kwi-workpiece, enokuthi ingabi yinto efanelekileyo kwizicelo ze-tungsten carbide. Abaqhubi kufuneka babeke iliso ngononophelo iiparamitha ukuthintela ubushushu obugqithisileyo.

Umgangatho weeWelds

Ukuwelda kwe-TIG ngokuqhelekileyo kuvelisa iiweldi ezicocekileyo, ezikumgangatho ophezulu ezineziphene ezimbalwa xa kuthelekiswa ne-MIG welding. Nangona kunjalo, umgangatho we-MIG welds unokuphuculwa ngobuchule obufanelekileyo kunye nezixhobo, ngakumbi xa kusetyenziswa iinkqubo ze-MIG eziphucukileyo ezenzelwe ukuchaneka.

Izixhobo kunye noLondolozo

Izixhobo ze-TIG zokuwelda zinzima kakhulu kwaye zinokufuna ukulungiswa okungaphezulu kuneenkqubo ze-MIG. Abanini-zithuthi kufuneka baqwalasele iziseko zophuhliso kunye nenkxaso ekhoyo kwindlela nganye yokuwelda xa besenza ukhetho lwabo.

5. Isiphelo

Zombini iindlela zokuwelda ze-TIG kunye ne-MIG zinendawo yazo kwi-welding ye-tungsten carbide saw tips, nganye inikezela ngeenzuzo kunye nemingeni eyahlukileyo. I-TIG ye-welding igqwesa ngokuchaneka, ukulawula, kunye nokuveliswa kwee-welds ezikumgangatho ophezulu kunye nefuthe elincinci lobushushu, okwenza ukuba lilungele izicelo apho ezi zinto zibaluleke kakhulu. Ngakolunye uhlangothi, i-MIG yelding ibonelela ngesantya, ukukhululeka kokusetyenziswa, kunye nokusebenza kakuhle kweendleko, ngakumbi kwiimeko zokuvelisa umthamo ophezulu.

Ekugqibeleni, ukhetho phakathi kwe-TIG kunye ne-MIG welding kufuneka ikhokelwe kwiimfuno ezithile zesicelo, kubandakanya ubukhulu bezinto eziphathekayo, umthamo wemveliso, kunye nomgangatho ofunekayo we-weld. Ngokuqonda amandla kunye nokunciphisa indlela nganye, abavelisi banokwenza izigqibo ezinolwazi eziphucula ukusebenza kunye nokuthembeka kwezixhobo ze-tungsten carbide.
