11. Ke Hobane'ng ha U Lokela ho Khetha Tšepe ea Womic?

- Lab ea R&D le QA ea ka hare

- Ketane e tsitsitseng ea phepelo ea thepa e tala e netefatsa hore ho na le linako tse khutšoane tsa ho fana ka thepa

- Lilemo tse mashome tsa phihlelo ea tšepe, haholo-holo litšepe tse kopantsoeng tsa mocheso o phahameng

- Ho latela ka botlalo le litokomane bakeng sa ho latela melao ea lisebelisoa tsa khatello

- Mofani oa tharollo ea sebaka se le seng bakeng sa ho reka, ho sebetsana le ho romela kantle ho naha litsamaiso tsa liphaephe tsa tšepe e sa hloekang

Bakeng sa maqephe a data a tekheniki, litheko le litheko tsa projeke tse ikhethileng, ikopanye le Womic Steel kajeno. Re itokiselitse ho tšehetsa litlhoko tsa hau tsa liphaephe tse sebetsang hantle ka ho nepahala, lebelo le botšepehi.

Khetha Womic Steel Group e le molekane oa hau ea tšepahalang bakeng saLiphaephe tsa Tšepe e sa Khaotsengle ts'ebetso e sa hlōloeng ea ho fana ka thepa. Rea u amohela!
