6.Kurapa Kupisa & Kushanda
Annealing: kupisa pamusoro peshanduko renji, kunonoka kutonhora.
Normalizing: natsa chimiro chezviyo, kuvandudza kuoma.
Kudzima & Kupisa: kugumira kuburikidza-kuomesa; kesi kuomesa zvinokurudzirwa.
Carburizing: zvakajairika kune SAE 1020 kune yakaoma nzvimbo / yakaoma musimboti.
Cold Working: inowedzera simba, inoderedza ductility.
7. Weldability & Fabrication
Weldability:Kugona. Maitiro akajairika: SMAW, GMAW (MIG), GTAW (TIG), FCAW. Preheat kazhinji haidiwe kune yakajairika makubvu; tevera welding maitiro ekutsanangurwa (WPS) yezvimiro zvakakosha.
Brazing / Soldering:maitiro akajairika anoshanda.
Machinability:Zvakanaka - 1020 michina nyore; inotonhora-inodhonzwa mbariro muchina zvakasiyana kubva annealed mbariro (zvishandiso uye parameters akagadziridzwa).
Kugadzira / Kupeta:Zvakanaka ductility mune annealed state; kubhenda radius miganhu zvinoenderana ukobvu uye mamiriro.
8. Standard Forms, Size & Tolerances
Womic Steel inopa mabhawa mumasaizi akafanana ekutengesa. Custom sizes inowanikwa pakukumbira.
Mafomu ekupa akajairika:
Round bars: Ø6 mm kusvika Ø200 mm (dhayamita renji zvinoenderana nekugona kweguyo)
Square mbariro: 6 × 6 mm kusvika 150 × 150 mm
Flat / rectangular mabara: ukobvu uye hupamhi kurongeka
Kucheka-kusvika-kureba, sawn, kana kupisa-kuchekwa magumo; nzvimbo isina centerless uye akatendeuka akapedzwa mabara aripo.
Tolerances & pamusoro pekupedzisira:
Kushivirira kunotevera kutariswa kwemutengi kana zviyero zvinoshanda (ASTM A29 / A108 kana zvakaenzana kune kutonhora-kupedzwa shafts). Womic Simbi inogona kupa chaiyo pasi (h9/h8) kana kutendeudzira kune zvinodiwa.
