Pehea e haku ai i ke kihi wiliwili i ka hikiwawe e pale aku i na hemahema

ʻO nā mākau welding i kapa ʻia ʻo ia nā ʻano welding maʻalahi, pololei ke kihi electrode a me ka hana ʻana, a ʻaʻole ʻino loa kāu welds.

I ka hoʻomaka ʻana o ke kuʻi ʻana, ma muli o ka ʻike ʻole o ka puʻupuʻu welding a me nā ʻenehana lawelawe ʻole, e hoʻomaha ia.Inā ʻoi aku ka hohonu a me ka pāpaʻu, e maʻalahi ka pores, like ke kākau ʻana, hahau ʻia.

Nui nā hemahema o ka welding:

1.External undercut

ʻAʻole pololei ke koho ʻana i ke kaʻina hana welding a ʻaʻole maʻamau ka hana, ʻo ke kuʻi ʻana ma nā ʻāpana metala kumu o ka hoʻokumu ʻana o ke awāwa a i ʻole ke kaumaha, i kapa ʻia ʻo ka biting edge.(I ka hoʻomaka ʻana o ka welding no ka mea ʻaʻole ʻike i ka nui o kēia manawa a me ka paʻa ʻole o ka lima kuʻi ʻana he maʻalahi ke kumu o ka nahu ʻana, ʻo ka pale ʻana i ka hoʻomaʻamaʻa ʻana i nā ʻenehana welding, pono e kūpaʻa, mai hopohopo.)

He kiʻi kēia o ka undercut

2.Stomata

I ka wā wili, ʻaʻole e pakele ke kinoea i loko o ka loko i hoʻoheheʻe ʻia i ka wā e paʻa ai a noho i loko o ka weld e hana i kahi lua, i kapa ʻia he porosity.(I ka hoʻomaka ʻana o ka wiliwili ʻana, no ka hiki ʻole ke hopu i ka puʻupuʻu wili a me ka mākaukau ʻole o ka lawelawe ʻana i nā ʻāpana, e hoʻomaha ai. hahau i ka manawa.)

ʻO kēia ka lua ea o ka wili

3. ʻAʻole i komo, ʻaʻole i hoʻohui ʻia

Nui nā kumu no ka komo ʻole ʻana a me ka infusion, e like me ka liʻiliʻi loa o ka weld a i ʻole ke kihi o ka groove, ʻoi aku ka mānoanoa o ka ʻaoʻao, ka nui o ke anawaena electrode, ka wikiwiki o ka wiliwili a i ʻole ka lōʻihi arc, a pēlā aku. e hoʻopili ʻia e nā haumia i loko o ke awāwa, a ʻo nā haumia i hoʻoheheʻe ʻole ʻia e pili pū i ka hopena hui ʻana o ka weld.

(E hoʻomalu wale i ka wikiwiki o ka welding, nā ʻāpana o kēia manawa a me nā kaʻina hana ʻē aʻe i ka wā wili, e koho pono i ka nui o ke awāwa, a e wehe i ka unahi a me nā haumia ma ka ʻili o ke awāwa; pono e hoʻomaʻemaʻe maikaʻi ʻia ke kumu o ka uhi uhi hope.)

Ke komo ʻole ʻana

4.Burn ma

I loko o ke kaʻina hana hoʻoheheʻe, kahe ka metala i hoʻoheheʻe ʻia mai ke kua o ke awāwa, e hana ana i kahi kīnā perforated i kapa ʻia ʻo burn-through.(ʻO ke ʻano o ka pale ʻana, ʻo ia ka hōʻemi ʻana i ka manawa a hoʻemi i ka lua weld)

Hoʻopau nā kiʻi wiliwili

5. Unsightly welding ili

ʻO nā hemahema e like me ka lapping a me ka serpentine bead ke kumu ia ma muli o ka lohi wiliwili ʻana a me ka haʻahaʻa loa.(ʻO ke ala e pale aku ai, ʻo ia ka hoʻomaʻamaʻa hou ʻana a me ka hoʻopaʻa ʻana i ka wikiwiki wili kūpono.
