Izindlela Zokushisela Zokusebenza Okuthuthukisiwe Kwamathiphu e-Tungsten Carbide Saw

    I-Welding tungsten carbide (WC) yabona amathiphu kumathuluzi okusika kuyinqubo ebucayi enethonya elikhulu ekusebenzeni nokuphila isikhathi eside kwama-saha blades. I-Tungsten carbide, eyaziwa ngobulukhuni bayo obukhethekile kanye nokumelana nokugqoka, isetshenziswa kabanzi ezinhlelweni ezahlukahlukene zezimboni. Nokho, ukusebenza kahle kwalawa macebiso kuncike kakhulu ezindleleni zokushisela ezisetshenziswayo. Lesi sihloko sihlola amasu e-welding ahlukene athuthukisa ukusebenza kwe-tungsten carbide saw amathiphu, agxile ebuhleni nasekusetshenzisweni kwawo.

1. Ukubaluleka Kokushisela Ekusebenzeni Kwamathuluzi

    Umgomo oyinhloko wokushisela amathiphu we-tungsten carbide kuma-saw blades uwukwakha isibopho esiqinile esingamelana nokucindezeleka okuphezulu okuhlangatshezwana nakho ngesikhathi sokusika. Izinga le weld libalulekile; ukushisela okwenziwa kabi kungaholela ekuhlulekeni kwethiphu ngaphambi kwesikhathi, ukunciphisa ukusebenza kahle kokusika, nokwenyuka kwezindleko zokusebenza. Ngakho-ke, ukukhetha indlela efanele yokushisela kubalulekile ukuze kuthuthukiswe ukusebenza kwamathuluzi.

2. Izindlela Zokushisela Ezivamile

I-TIG Welding (Tungsten Inert Gas)

    Ukushisela kwe-TIG kungenye yezindlela ezivame ukusetshenziswa kakhulu zokunamathisela amathiphu e-tungsten carbide ngenxa yokunemba kwawo nokulawula okokufaka ukushisa. Kule nqubo, i-electrode ye-tungsten engasebenziseki ikhiqiza i-arc encibilikisa izinto eziyisisekelo kanye nensimbi yokugcwalisa, okuvame ukuba yi-alloy esekelwe ku-nickel. Isivikelo segesi engenzi lutho sivikela i-weld pool ekungcoleni.

Izinzuzo:

Ukunemba okuphezulu:Ukushisela kwe-TIG kuvumela ukulawula okuhle phezu kwemingcele yokushisela, okuyenza ifanele imiklamo eyinkimbinkimbi nezinto ezincane.

Indawo Eyehlisiwe Ethinteke Ukushisa (HAZ):Lokhu kunciphisa ukuhlanekezela okushisayo, kugcina ubulukhuni be-tungsten carbide.

I-MIG Welding (I-Metal Inert Gas)

    Ukushisela kwe-MIG kusebenzisa intambo yokuphakelayo eqhubekayo njenge-electrode futhi isebenzisa igesi engasebenzi ukuze ivikeleke. Nakuba ngokuvamile kushesha kakhulu kunokushisela kwe-TIG, ukushisela kwe-MIG kungethula ukushisa okwengeziwe endaweni yokusebenza, okungenzeka kungafaneleki ezinhlelweni ze-tungsten carbide.

Izinzuzo:

Isivinini:I-MIG welding ilungele ukukhiqizwa kwevolumu ephezulu ngenxa yejubane layo lokushisela ngokushesha.

Ukuhlukahluka:Ingasetshenziswa ezintweni ezihlukahlukene kanye nokuqina.

I-Laser Welding

I-laser welding ithole ukuthandwa embonini ye-hardmetal ngekhono layo lokukhiqiza ama-welds ekhwalithi ephezulu anomthelela omncane oshisayo. Le nqubo isebenzisa i-laser beam egxilile ukuze incibilikise izinto eziyisisekelo, idale isibopho esiqinile nge-HAZ encane kakhulu.

Izinzuzo:

Ukunemba:Ukushisela nge-laser kuvumela ukulawula okunembile nokubekwa kwe-weld, okubalulekile kumajometri ayinkimbinkimbi.

Ukuhlanekezela Okuncane:Ukufakwa kokushisa okuphansi kunciphisa kakhulu ingozi yokuguqa noma ukwehlisa izakhiwo ze-carbide.

Ukubhuqa

I-Brazing, nakuba kungeyona indlela yendabuko yokushisela, ihlanganisa ukuhlanganisa amathiphu e-tungsten carbide ezinsikeni zensimbi kusetshenziswa insimbi yokugcwalisa encibilika ekushiseni okuphansi kunezinto eziyisisekelo. Le ndlela iwusizo ikakhulukazi lapho usebenza ngezinto ezingafani noma lapho ugwema ukushisa okudlulele kubalulekile.

Izinzuzo:

Izinga Lokushisa Eliphansi:Iphuzu eliphansi lokuncibilika lensimbi yokugcwalisa lisiza ukugcina izakhiwo ze-tungsten carbide.

Ukuhambelana Kwezinto Ezingafani:I-Brazing iyasebenza ekuhlanganiseni izinto ezinezici ezihlukile zokunweba ezishisayo.

3. Ukucatshangelwa kwe-Optimal Welding

Pre-Weld Ukulungiselela

Ukulungiswa kwendawo okusebenzayo kubalulekile ukuze kutholakale ukushisela okuqinile. Kokubili amathiphu e-tungsten carbide kanye ne-substrate kufanele kuhlanzeke futhi kungabi nakungcola. Amasu afana nokuqhunyiswa kwe-abrasive noma ukuhlanzwa kwamakhemikhali kungaqinisekisa izimo ezilungile zendawo.

Ukuphathwa Kokushisa

Ukulawula okokufaka ukushisa kubalulekile ukuvimbela ukulimala okushisayo ku-tungsten carbide. Ukushisa okudlulele kungaholela ekwehleni kwe-carbide, kuthinte kabi izakhiwo zayo zemishini. Ukusebenzisa amasu afana ne-pulse welding kungasiza ukunciphisa izinkinga zokushisa.

Ukwelashwa Kwangemva Kwe-Weld

Ukwelashwa kokushisa kwangemva kokushisela, njengokuthulisa noma ukukhulula ingcindezi, kungathuthukisa izici zemishini zejoyinti elishiselwe, kuqinisekise ukusebenza okungcono ngaphansi kwengcindezi yokusebenza.

4. Quality Control

Ukusebenzisa izinyathelo eziqinile zokulawula ikhwalithi kubalulekile ukuze kuqinisekiswe ukwethembeka kwamathiphu ashiselwe i-tungsten carbide. Izindlela zokuhlola okungabhubhisi (i-NDT), ezifana nokuhlolwa kwe-ultrasonic noma ukuhlolwa kokungena kodayi, kungasiza ukuhlonza amaphutha ngaphambi kokuba amathuluzi afakwe emsebenzini.

Isiphetho

Ukukhethwa kwendlela yokushisela kudlala indima ebalulekile ekusebenzeni kwamathiphu e-tungsten carbide saw. Ngokukhetha amasu afanele, ukuphatha okokufaka ukushisa, nokugcina ukulawulwa kwekhwalithi okuqinile, abakhiqizi bangathuthukisa kakhulu ukuqina nokusebenza kahle kwamathuluzi okusika. Njengoba imboni ye-hardmetal iqhubeka nokuvela, ukuthuthuka kwezobuchwepheshe bokushisela kuzothuthukisa amakhono kanye nokusetshenziswa kwamathuluzi e-tungsten carbide, kuqinise ukubaluleka kwawo ekukhiqizeni kwesimanje.
