Kev siv cov high zaus cua sov

1. Kev kho cua sov: hauv zos lossis tag nrho quenching, annealing, tempering thiab diathermy ntawm ntau yam hlau;

2. Kub sib sau: tag nrho daim forging, ib nrab forging, kub ntxhov siab, kub dov;

3. Welding: brazing ntawm ntau yam khoom hlau, vuam ntawm ntau yam cuab yeej, pom hniav, vuam ntawm steel kav, tooj liab kav, vuam ntawm tib yam thiab dissimilar hlau;

4. Hlau smelting: (nqus) smelting, casting thiab evaporative txheej ntawm kub, nyiaj, tooj liab, hlau, txhuas thiab lwm yam hlau;

1. Lwm daim ntawv thov ntawm lub tshuab cua sov ntau zaus: semiconductor ib leeg siv lead ua kev loj hlob, kev sib tw kub, lub raj mis lub qhov ncauj thaum tshav kub kub sealing, tshuaj txhuam hniav tawv nqaij kub sealing, hmoov txheej, hlau implantation yas
