Moyo wautumiki wanyundozimagwirizana ndi zida za nyundo yokha, mtundu wa zinthu zowonongeka, ndi zina zotero. Zida za nyundo ndizofunika kwambiri zomwe zimakhudza moyo wake. Mitundu ya nyundo pamsika imagawidwa m'magulu atatu: masamba a nyundo wamba, tungsten carbide spray welded nyundo, ndi tungsten carbide fusion welded nyundo.
Pakati pawo, malinga ngati chidutswa cha nyundo wamba ndi nyundo yotenthedwa ndi kutentha, kapena nyundo yachitsulo ya 65Mn imagwiritsidwa ntchito, mtengo wamtundu uwu wa nyundo ndi wotsika mtengo, koma moyo wogwirizana nawo umakhalanso wamfupi.
Nyundo zowotcherera za Tungsten carbide zimagwiritsidwa ntchito kwambiri pamsika, pogwiritsa ntchito ukadaulo wowotcherera wa oxyacetylene kupopera ufa wa tungsten carbide pa gawo lapansi la nyundo, ndiyeno kutentha kuchitira nyundo kutulutsa chomaliza. Komabe, chifukwa cha chilengedwe chaukali kupanga ndi chikoka cha tungsten carbide kuwotcherera waya khalidwe, khalidwe la chomaliza tungsten carbide nyundo ndi wosagwirizana, nthawi zambiri limodzi ndi zolakwika monga pores ndi inclusions mu wosanjikiza weld, kukhudza kwambiri moyo wake utumiki. Makamaka pamene zipangizo zolimba pang'ono zathyoledwa, zimakhala zosavuta kuchititsa kuti weld layer igwe. Kuonjezera apo, kupanga ndondomekoyi kumatsagana ndi fumbi lalikulu ndi mpweya woipa, womwe sungathe kukwaniritsa zokha, ndipo chiyembekezo sichimalonjeza kwambiri.
HMT's tungsten carbide fusion kuwotcherera nyundo utenga plasma kuwotcherera cladding luso, amene madipoziti wosanjikiza aloyi particles pa nyundo gawo lapansi, kukwaniritsa pafupifupi makulidwe ofanana pakati pa nyundo gawo lapansi ndi zolimba aloyi kuwotcherera wosanjikiza. Nthawi yomweyo, tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, kumathandizira kwambiri kumeta ubweya wa nyundo. HMT's hard alloy fusion welded welded nyundo zimagwira ntchito bwino kwambiri, zolimba kukana kuvala, moyo wautumiki, kukana kukhudzidwa, komanso kuphwanya bwino poyerekeza ndi tungsten carbide spray welded nyundo. Kuphatikiza apo, njira yopangirayi imatha kukhala yokhayokha komanso yogwirizana ndi chilengedwe, ndikupangitsa kuti ikhale yamakono pakupanga zidutswa zanyundo.
Kuphwanyidwa kwa zinthu kumakhudzanso kwambiri moyo wautumiki wa nyundo, ndipo kugwiritsa ntchito nyundo zosiyanasiyana kuphwanya zinthu zosiyanasiyana kungathandize kwambiri kuphwanya bwino. Zida zina zimakhala ndi kuuma kwakukulu, kotero mphamvu ya nyundo imakhalanso yamphamvu kwambiri. Mwachitsanzo, chakudya chansungwi ndi nyundo yowotchera ya tungsten carbide ikathyoka, wosanjikiza wowotcherera amatha kugwa. Pazinthu zovala kwambiri, kutalika kwa wosanjikiza wosavala kuyenera kukulitsidwa ndi 100mm, monga chakudya cha mankhusu. Palinso gulu la matabwa ophwanyidwa, omwe amakhala ndi mphamvu yayikulu komanso kuvala, ndipo nyundo zowotcherera za tungsten carbide sizingagwiritsidwe ntchito konse. Kwa nyundo wamba, moyo wawo wautumiki ndi waufupi. Pakuphwanyidwa kwa zinthu zotere, nyundo zowotcherera za HMT za hard alloy fusion zimatha kukwaniritsa zofunikira. Pambuyo pogwiritsidwa ntchito ndi wopanga matabwa ophwanyika, zatsimikiziridwa kuti nyundo zowotcherera za HMT zolimba za alloy fusion zimatha kukwaniritsa zofunikira. Kuphatikiza apo, chinyezi cha chimanga chimakhudzanso kwambiri kuphwanya bwino. Chinyezi chikakhala chambiri, kuvala kwa nyundo kumakhala kwakukulu ndipo moyo wautumiki umakhala wamfupi.
