    Injongo ephambili ye-welding tungsten carbide tips to saw blades kukudala ibhondi eyomeleleyo enokumelana noxinzelelo oluphezulu oludibana nayo ngexesha lokusika. Umgangatho wale weld ubalulekile; i-weld eyenziwe kakubi inokukhokelela ekungaphumeleli kwengcebiso kwangaphambi kwexesha, ukunciphisa ukusebenza kakuhle kokusika, kunye nokwanda kweendleko zokusebenza. Ke ngoko, ukukhetha indlela efanelekileyo ye-welding ibalulekile ekuphuculeni ukusebenza kwesixhobo.

2. Iindlela zeWelding eziqhelekileyo

TIG Welding (Tungsten Inert Gas)

    Ukuwelda kwe-TIG yenye yezona ndlela zixhaphakileyo zokuncamathisela iingcebiso ze-tungsten carbide ngenxa yokuchaneka kwayo kunye nokulawula igalelo lobushushu. Kule nkqubo, i-electrode ye-tungsten engasetyenziswayo ivelisa i-arc enyibilikisa izinto ezisisiseko kunye nentsimbi yokuzalisa, ngokuqhelekileyo i-alloy-based alloy. Isikhuselo segesi engasebenziyo sikhusela i-weld pool ekungcoleni.

Izinto eziluncedo:

Ukuchaneka okuphezulu:Ukuwelda kwe-TIG ivumela ulawulo olululo kwiiparamitha ze-welding, iyenze ifaneleke kuyilo oluntsonkothileyo kunye nezixhobo ezincinci.

Indawo eNcitshiswe bubushushu (HAZ):Oku kunciphisa ukuphazamiseka kwe-thermal, ukugcina ubulukhuni be-tungsten carbide.

Ukuwelda kwe-MIG (igesi yeMetal inert)

    I-MIG welding isebenzisa i-fidi yocingo eqhubekayo njenge-electrode kwaye isebenzisa igesi engasebenziyo ukukhusela. Ngelixa ngokubanzi ngokukhawuleza kune-TIG welding, i-MIG yelding inokwazisa ubushushu obuninzi kwi-workpiece, enokuthi ingabi yinto efanelekileyo kwizicelo ze-tungsten carbide.

Izinto eziluncedo:

Isantya:I-MIG yokuwelda ifanelekile kwimveliso ephezulu ngenxa yesantya sayo esikhawulezayo.

Ukuguquguquka:Ingasetyenziselwa kwizinto ezahlukeneyo kunye nobukhulu.

Laser Welding

I-laser welding ifumene ukuthandwa kwishishini le-hardmetal ngenxa yokukwazi ukuvelisa i-welds ezikumgangatho ophezulu kunye nefuthe elincinci lobushushu. Olu buchule lusebenzisa i-laser beam egxininisiweyo ukunyibilikisa izinto ezisisiseko, ukudala ibhondi eyomeleleyo kunye ne-HAZ emxinwa kakhulu.

Izinto eziluncedo:

Ukuchaneka:I-laser welding ivumela ulawulo oluchanekileyo kunye nokubekwa kwe-weld, ebaluleke kakhulu kwiijometri ezinzima.

Ukugqwesa okuncinci:Igalelo lokushisa eliphantsi linciphisa kakhulu umngcipheko wokulwa okanye ukuthotywa kweempawu ze-carbide.

Ukugqabhuka

I-Brazing, ngelixa ingekho indlela ye-welding yendabuko, ibandakanya ukudibanisa iingcebiso ze-tungsten carbide kwiintsimbi zetsimbi usebenzisa i-filler metal inyibilika kwiqondo lokushisa eliphantsi kunezixhobo ezisisiseko. Le ndlela iluncedo ngakumbi xa usebenza ngezinto ezingafaniyo okanye xa ukuphepha ubushushu obugqithisileyo kubalulekile.

Izinto eziluncedo:

Ubushushu obusezantsi:Indawo ephantsi yokunyibilika yentsimbi yokuzalisa inceda ukugcina iipropati ze-tungsten carbide.

Ukuhambelana kwezinto ezingafaniyo:I-Brazing iyasebenza ekudibaniseni izinto ezineempawu ezahlukeneyo zokwandiswa kwe-thermal.

3. Iingqwalasela ze-Optimal Welding

Ukulungiselela kwangaphambili kweWeld

Ukulungiswa komphezulu okusebenzayo kubalulekile ekufezekiseni i-welds eqinile. Zombini iingcebiso ze-tungsten carbide kunye ne-substrate kufuneka zicoceke kwaye zingabikho kwizinto ezingcolileyo. Ubuchwephesha obufana nokuqhunyiswa kwe-abrasive okanye ukucocwa kweekhemikhali kunokuqinisekisa iimeko ezifanelekileyo zomphezulu.

Ulawulo lobushushu

Ukulawula igalelo lobushushu kubalulekile ukukhusela umonakalo we-thermal kwi-tungsten carbide. Ukushisa okugqithisileyo kunokukhokelela kwi-carbide coarsening, echaphazela kakubi iimpawu zayo zomatshini. Ukusebenzisa iindlela ezifana ne-pulse welding kunokunceda ukunciphisa imiba yobushushu.
