Hahi hahiHiki ke ?ike ?ia nā ?āpana kauā ma nā wahi āpau i ko mākou ola i kēlā me kēia lā. Ke hana ?ia nā ?āpana kūpana metala i nā nui he nui, e loa?a nā pilikia like ?ole ma muli o nā kumu like ?ole. E hāhai kākou i kamea hana hahi metala e ho?omaopopo:

Nā pilikia ma?amau i ka hana ?ana i nā hahi keleawe a me nā ?āpana kau.

1. ?A?ole kūlike ke kinona a me ka nui o ka hahi ?ana o nā hao a me nā kaha ki?i ?ana

?A?ole nā ??kumu hahi i nā ?āpana a me ka nui ke kumu nui no ka mea ?a?ole e ?ae ?ia ka puna a me ka ho?onohonoho ?ana, a me nā hana e hō?emi ai i ka rebound, akā pono e ho?omaika?i i ka hilina?i o ka ho?onohonoho hakahaka.

2. ?O ke aniani o luna o nā huki huki ?ana i nā ?āpana

?O ke kūpikipiki o nā wahi hahi metala ke kumu o nā koho pono ?ole, ha?aha?a pa?akikī o ka mālama ?ana i ka wela, ho?opau maika?i ?ole, ?aule?a i nā kihi make pōkole, ka maika?i ?ole o ke kūlou hakahaka, ka mānoanoa o nā mea, ke koho kūpono ?ole o ka ho?olālā ?enehana, ka nele o ka lubrication a kumu ?ē a?e.

3. Metal hahi?ana tensile anuenue kapili

(1) Inā ?a?ole kūlike ka Angle i waena o ka laina anuenue a me ke kuhikuhi huila e wili nei i ka pepa metala me ka ?ōkuhi i hō?ike ?ia, pono ke laina kūlou i ka ?ao?ao palaoa e ?ōwili nei i ka hihia o ke kūlou ?ano V ?ole like. ?ulupā bidirectional, ka laina anuenue a me ke kuhikuhi o ka palaoa e ka?a i 45 kekelē.

(2) Pelekikena maika?i ?ole o nā mea pono.

(3) ?O ka radius anuenue li?ili?i, maika?i maika?i pickling.

(4) ?A?ole lawa ka lubrication - ki?eki?e ka hakakā.

(5) Kuhi ?ia ke kahapuni Angle o ka convex / concave die a li?ili?i paha ka ?ae - ho?onui ka pale pale hānai.

(6) maika?i maika?i ?ole o ka ho?opa?a ?ana a me ke ku?i ?ana i ka ?oki o nā ?āpana kau - burr a crack.

(7) Mānoanoa a me ka nui o nā mea ma waho o ke ahonui - pa?akikī i ka hānai ?ana

Nā hopena i ka hahi ?ana o ka hao a me nā ?āpana kau.

1. E ma?alahi a ma?alahi ho?i ke kahakaha ?ana o ke metala i ke kaha ki?i ?ana, hiki ke kaha ki?i ?ana i ho?okahi manawa e like me ka hiki;

2. No nā ?āpana e pono e ho?olō?ihi ?ia i nā manawa he nui, nā ?ūmi e hiki ke hana i ke ka?ina o ke kau ?ana e ?ae ?ia e noho i loko a ma waho ma ke kahua o ka hō?oia ?ana i ke ?ano o ke ?ano e pono ai;

3. Ma lalo o ke kumu o ka hō?oia ?ana i nā koi ho?onohonoho, e ?ae ?ia ka paia ?ao?ao o nā ?āpana hohola i kahi pali;

4. ?O ke ākea ma waena o ka lihi o ka lua ma ka lalo a i ?ole ka lapalapa o ka ?āpana kaha ki?i a me ka paia ?ao?ao e kūpono;

5. ?O ka lalo a me ka paia o ka ?āpana kaha ki?i, ka lapalapa a me ka paia, a me ka lepe o ka huina o nā kihi ?ehā o ka ?āpana huinahā e pono;

6. ?A?ole e lepili pū ?ia nā ana o nā hahi a me nā ?āpana hohola me nā ana o waho.

?O ka mea i luna a?e nei e pili ana i ka hahi ?ana i nā ?āpana i nā ?āpana o nā pilikia ma?amau a me nā hopena, lana ko?u mana?o e kōkua iā ?oe hui hahi hao, inā ?oe e pono pono i ka ho?opa?a ?ana i ka hao, e ?olu?olu kāhea iā mā ~ ~
