Kodi Hard face ndi chiyani?

Kuyang'ana molimba, komwe kumadziwikanso kuti hard surfacing, ndi njira yopangira zitsulo poyika zitsulo zolimba, ma aloyi otentha kwambiri, zoumba ndi zina zokutira zitsulo zoyambira kuti ziwonjezere kuvala, dzimbiri, kulimba ndi mawonekedwe ena amthupi ndi mankhwala achitsulo choyambira.

ndi zokutira zina zomangira zitsulo kuti ziwonjezere kuvala koyenera, dzimbiri, kuuma ndi mawonekedwe ena akuthupi ndi mankhwala achitsulo choyambira.

Pamene Hard nkhope?

Kuyang'ana molimba nthawi zonse kumagwiritsidwa ntchito nthawi yonse ya moyo wa gawo lopangidwa kapena makina. Kawirikawiri, kuyang'ana kolimba kumagwiritsidwa ntchito.

Pa mbali zatsopano kuonjezera kuvala kukana.

Pamalo ogwiritsidwa ntchito, owonongeka kubwereranso kulolera, kutalikitsa moyo wogwira ntchito.

Pazida zogwirira ntchito kuti ziwonjezere moyo wazinthu zopangidwa ngati gawo la pulogalamu yokonza.

Kodi Hard Face imayikidwa bwanji?

Pali njira zambiri zogwiritsira ntchito mawonekedwe ovuta. Njirazi zimagwiritsidwa ntchito pazinthu zosiyanasiyana. Kotero palibe njira imodzi yomwe ili yabwino kuposa ina, m'malo mwake njirayo imalimbikitsidwa potengera cholinga cha zovutazo. Zina mwa njira zowotcherera zodziwika bwino ndi izi:

1. Kuwotcherera kwa Metal Arc (SMAW)

2. Gas Metal Arc Welding (GMAW)

3. Kuwotcherera kwa Oxyfuel (OFW)

4. Submerged Arc Welding (SAW)

5. Kuwotcherera Magetsi (ESW)

6. Plasma Transferred Arc Welding (PTAW)

7. Kupopera mbewu kwa matenthedwe

8. Cold polima mankhwala

9. Laser Cladding

Kuyang'ana movutikira kwaphatikizidwa m'mapulogalamu ogulira ndi kukonza mafakitale osiyanasiyana kuphatikiza, koma osachepera, Zitsulo, Simenti, Migodi, Petrochemical, Mphamvu, Nzimbe ndi Chakudya, Process Chemical, komanso opanga wamba.

Zida ndi Mtengo wa zovuta zoyang'ana

Njira yovuta yogwirira ntchito imadalira geometry ya gawolo ndi mtengo wamtengo wapatali wa njira yovuta. Mitengo imatha kusiyanasiyana malinga ndi kuchuluka kwa zinthuzo.

Kusiyanasiyana kwa mtengo uku kungafotokozedwe mwachidule motere:

•Flux-cored arc welding (FCAW) 8 mpaka 25 lb/hr

•Shielded Metal Arc Welding (SMAW) 3 mpaka 5 lb/hr

•Kuwotcherera kwa Gasi Metal Arc (GMAW), kuphatikiza zonse zotetezedwa ndi gasi komanso kutsegulira kwa arc 5 mpaka 12 lb/hr

•Kuwotcherera kwa Oxyfuel (OFW) 5 mpaka 10 lb/h

Ngati mukufuna kudziwa zambiri za njira zolimba, kugwiritsa ntchito, kapena kuyang'ana zokambilana, funsani zzbetter carbide.
