Ukuqhathanisa Amasu Wokushisela: I-TIG vs. MIG ye-Tungsten Carbide Saw Amathiphu

    I-Welding tungsten carbide (WC) yabona amathiphu kumathuluzi okusika kuyinqubo eyisisekelo embonini ye-hardmetal, enomthelela ekusebenzeni nokuqina kwamathuluzi. Amasu amabili okushisela asetshenziswa kakhulu kulolu hlelo ukushisela i-Tungsten Inert Gas (TIG) kanye ne-Metal Inert Gas (MIG) yokushisela. Indlela ngayinye inezinzuzo zayo kanye nokulinganiselwa kwayo, okwenza kubaluleke kubakhiqizi ukukhetha indlela efanele ngokusekelwe ezidingweni ezithile. Lesi sihloko siqhathanisa i-TIG ne-MIG welding kumongo wezinhlelo zokusebenza ze-tungsten carbide, igxile ezinqubweni zabo, izinzuzo, nokucatshangelwa kokusetshenziswa.

1. Sibutsetelo Welding Techniques

I-TIG Welding

I-TIG welding iyinqubo esebenzisa i-electrode ye-tungsten engadleki ukukhiqiza i-arc encibilikisa izinto zokusebenza kanye nenduku yokugcwalisa. I-weld pool ivikelwe ekungcolisweni yigesi ye-inert, ngokuvamile i-argon noma i-helium. Le ndlela yaziwa ngokunemba nekhono layo lokukhiqiza amashisela ekhwalithi ephezulu, ikakhulukazi ezintweni ezincane.

I-MIG Welding

I-MIG, ngakolunye uhlangothi, isebenzisa i-electrode yocingo esetshenziswayo eqhubekayo negesi engasebenzi ukuze ivikeleke. Le nqubo ibonakala ngesivinini nokusebenza kahle kwayo, okwenza ifanelekele ukukhiqizwa kwevolumu ephezulu. Ukushisela kwe-MIG kuvame ukuncanyelwa ezintweni eziwugqinsi ngenxa yamazinga ayo aphezulu okubekwa.

2. Izinzuzo TIG Welding

Ukunemba nokulawula

Enye yezinzuzo eziyinhloko ze-TIG welding ukunemba kwayo okungavamile. I-welder inokulawula okukhudlwana kokufaka kokushisa, okubalulekile lapho ushisela i-tungsten carbide. Lokhu kubaluleke kakhulu ngoba ukushisa okudlulele kungaholela ekwehleni kwe-carbide, kuthinte kabi ubulukhuni nokumelana nokugqoka.

Indawo Ethintekile Ukushisa Okuncane (HAZ)

Ukushisela kwe-TIG kukhiqiza i-HAZ encane uma iqhathaniswa ne-MIG yokushisela. Le HAZ encishisiwe inenzuzo uma usebenza ne-tungsten carbide, njengoba inciphisa ubungozi bokushintsha i-microstructure ye-carbide kanye nezakhiwo.

Ukuguquguquka

Ukushisela kwe-TIG kuguquguquka kakhulu futhi kungasetshenziswa ezinhlobonhlobo zezinto, kufaka phakathi izinsimbi ezingafani. Lokhu kuvumelana nezimo kunenzuzo ezinhlelweni zokusebenza lapho amathiphu e-tungsten carbide edinga ukushiselwa kuma-substrates ahlukahlukene, njengensimbi enesivinini esikhulu noma insimbi yamathuluzi.

3. Izinzuzo ze-MIG Welding

Isivinini kanye Nempumelelo

Ukushisela kwe-MIG ngokuvamile kuyashesha kune-TIG yokushisela ngenxa yendlela yayo yokuphakelayo ngocingo eqhubekayo. Lokhu kusebenza kahle kuyenza ilungele izindawo zokukhiqiza ezinkulu lapho isikhathi siyisici esibalulekile. Ikhono lokushisela amathiphu amaningi ngokushesha lingathuthukisa kakhulu ukukhiqiza.

Ukusebenziseka kalula

Ukushisela kwe-MIG kuvame kuthathwa njengokulula ukufunda nokusebenza kunokushisela kwe-TIG. Inqubo idinga ikhono elincane, okwenza ifinyeleleke kubasebenzisi abanamazinga ahlukahlukene okuhlangenwe nakho. Lokhu kulula ukuyisebenzisa kunganciphisa izindleko zokuqeqesha futhi kuthuthukise ukusebenza kahle komsebenzi.

Izindleko-Ngempumelelo

Ngenxa yamazinga ayo aphezulu okufakwa kanye nesivinini sokushisela esisheshayo, ukushisela kwe-MIG kungabiza kakhulu kwezinye izinhlelo zokusebenza. Lokhu kuyiqiniso ikakhulukazi ezimeni lapho kudingeka umthamo omkhulu wokukhiqiza, njengoba sonke isikhathi nezindleko zabasebenzi zingancishiswa kakhulu.

4. Ukucatshangelwa Okubalulekile

Ukuphathwa Kokushisa

Nakuba ukushisela kwe-TIG kunikeza ukulawula okuphakeme kokufaka ukushisa, kudinga u-opharetha onekhono ukuze aphathe inqubo ngempumelelo. Ngokuphambene, ukushisela kwe-MIG kungethula ukushisa okwengeziwe endaweni yokusebenza, okungenzeka kungafaneleki ezinhlelweni ze-tungsten carbide. Ama-opharetha kufanele aqaphe ngokucophelela amapharamitha ukuvimbela ukushisa ngokweqile.

Ikhwalithi ye-Welds

Ukushisela kwe-TIG kuvame ukukhiqiza amashisela ahlanzekile, ekhwalithi ephezulu anokukhubazeka okumbalwa uma kuqhathaniswa nokushisela kwe-MIG. Kodwa-ke, ikhwalithi yokushisela kwe-MIG ingathuthukiswa ngendlela efanele kanye nemishini, ikakhulukazi uma kusetshenziswa amasistimu e-MIG athuthukisiwe aklanyelwe ukunemba.

Izinsiza kanye Nesondlo

Imishini yokushisela ye-TIG ngokuvamile iyinkimbinkimbi futhi ingase idinge ukunakekelwa okwengeziwe kunezinhlelo ze-MIG. Abasebenzisi kufanele bacabangele ingqalasizinda nokusekelwa okutholakalayo kwendlela yokushisela ngayinye lapho benza ukukhetha kwabo.

5. Isiphetho

Zombili izindlela zokushisela ze-TIG ne-MIG zinendawo yazo ekushiseleni amathiphu esaha ye-tungsten carbide, ngalinye linikeza izinzuzo nezinselele ezihlukile. Ukushisela kwe-TIG kuhamba kahle ngokunemba, ukulawula, kanye nokukhiqizwa kwamashisela ekhwalithi ephezulu anomthelela omncane wokushisa, okuyenza ifanelekele izinhlelo zokusebenza lapho lezi zici zibaluleke kakhulu. Ngakolunye uhlangothi, ukushisela kwe-MIG kunikeza isivinini, ukusebenziseka kalula, kanye nokusebenza kahle kwezindleko, ikakhulukazi ezimweni zokukhiqiza zevolumu ephezulu.

Ekugcineni, ukukhetha phakathi kokushisela kwe-TIG ne-MIG kufanele kuqondiswe yizidingo ezithile zohlelo lokusebenza, okuhlanganisa ukujiya kwempahla, umthamo wokukhiqiza, kanye nekhwalithi yokushisela efiswayo. Ngokuqonda amandla nokulinganiselwa kwendlela ngayinye, abakhiqizi bangenza izinqumo ezinolwazi ezithuthukisa ukusebenza nokuthembeka kwamathuluzi we-tungsten carbide.
