Moyo wautumiki watsamba la nyundoikugwirizana ndi zinthu zomwe zili mu tsamba la nyundo, mtundu wa zinthu zomwe zaphwanyidwa, ndi zina zotero. Zinthu zomwe zili mu tsamba la nyundo ndi chinthu chofunikira kwambiri chomwe chimakhudza moyo wake. Masamba a nyundo omwe ali pamsika amagawidwa m'magulu atatu: masamba wamba a nyundo, masamba a nyundo opangidwa ndi tungsten carbide spray, ndi masamba a nyundo opangidwa ndi tungsten carbide fusion.
Pakati pawo, bola ngati chidutswa cha nyundo wamba ndi chidutswa cha nyundo chotenthetsera kutentha, kapena chidutswa cha nyundo chachitsulo cha 65Mn chikugwiritsidwa ntchito, mtengo wa chidutswa cha nyundo chamtunduwu ndi wotsika mtengo, koma nthawi yogwirira ntchito yofanana nayo ndi yochepa.
Nyundo zolumikizira za Tungsten carbide spray zimagwiritsidwa ntchito kwambiri pamsika, pogwiritsa ntchito ukadaulo wa oxyacetylene spray welding popopera ufa wa tungsten carbide weld pa nyundo, kenako n’kutenthetsa nyundo kuti ipange chinthu chomaliza. Komabe, chifukwa cha malo ovuta opangira komanso mphamvu ya waya wolumikizira wa tungsten carbide, ubwino wa nyundo yomaliza ya tungsten carbide sumafanana, nthawi zambiri umaphatikizidwa ndi zolakwika monga ma pores ndi zinthu zomwe zili mu weld layer, zomwe zimakhudza kwambiri moyo wake wa ntchito. Makamaka pamene zipangizo zolimba pang'ono zasweka, zimakhala zosavuta kupangitsa kuti weld layer igwe. Kuphatikiza apo, njira yopangira imaphatikizidwa ndi fumbi lalikulu ndi mpweya woipa, zomwe sizingakwaniritse zokha, ndipo zomwe zikuyembekezeka sizili zabwino kwenikweni.
Nyundo zolumikizirana za HMT za tungsten carbide fusion welding hammers zimagwiritsa ntchito ukadaulo wolumikizirana wa plasma welding cladding, womwe umayika tinthu tating'onoting'ono tolimba pa nyundo, zomwe zimapangitsa kuti makulidwe ofanana pakati pa nyundo ndi nyundo yolimba. Nthawi yomweyo, tinthu tating'onoting'ono tolimba ta alloy tikhale ndi mbali zosiyanasiyana, zomwe zimapangitsa kuti nyundo igwire bwino ntchito. Zidutswa za nyundo zolumikizidwa za HMT hard alloy fusion welded zili ndi magwiridwe antchito abwino kwambiri, ndi kukana kuvala bwino, nthawi yogwira ntchito, kukana kukhudza, komanso kugwira ntchito bwino poyerekeza ndi zidutswa za nyundo zolumikizidwa za tungsten carbide spray. Kuphatikiza apo, njira yopangira imatha kukhala yodziyimira yokha komanso yosamalira chilengedwe, zomwe zimapangitsa kuti ikhale njira yamakono yopangira zidutswa za nyundo.
Kuphwanya zipangizo kumakhudzanso kwambiri moyo wa ntchito ya nyundo, ndipo kugwiritsa ntchito nyundo zosiyanasiyana kuphwanya zipangizo zosiyanasiyana kungathandize kwambiri kuphwanya. Zipangizo zina zimakhala zolimba kwambiri, kotero mphamvu yokhudza nyundo nayonso imakhala yamphamvu kwambiri. Mwachitsanzo, pamene chakudya cha nsungwi ndi nyundo yothira tungsten carbide spray welding zasweka, wosanjikiza wa weld umatha kugwa. Pa zipangizo zomwe zimawonongeka kwambiri, kutalika kwa wosanjikiza wosawonongeka kuyenera kuwonjezeredwa ndi 100mm, monga chakudya cha tirigu. Palinso gulu la matabwa ophwanyika, omwe ali ndi mphamvu yokhudza kwambiri komanso kuwonongeka, ndipo nyundo zothira tungsten carbide spray welding sizingagwiritsidwe ntchito konse. Pa nyundo wamba, nthawi yawo yogwirira ntchito ndi yochepa. Pa kuphwanya zipangizo zotere, nyundo zothira chitsulo zolimba za HMT zimatha kukwaniritsa zofunikira bwino kwambiri. Pambuyo pogwiritsidwa ntchito ndi wopanga matabwa ophwanyika, zatsimikiziridwa kuti nyundo zothira chitsulo zolimba za HMT zimatha kukwaniritsa zofunikira bwino kwambiri. Kuphatikiza apo, chinyezi cha chimanga chimakhudzanso kwambiri pakugwira ntchito bwino kwa kuphwanya. Chinyezi chikakhala chochuluka, nyundo imakhala yogwira ntchito kwambiri ndipo nthawi yogwira ntchito imakhala yochepa.
