E hoʻohana:
He electrode welding versatile kēia no ka hoʻoheheʻe ʻana i ke kila kalapona a i ʻole nā mea kila kila a me nā kiwi me kahi mahana hana ma lalo o 450 ° C.

MAHELE:
⒈ kuʻihao electrode e 300 ~ 350 ℃ baking 1h.
⒉ pre-weld i ka mea hana e hoʻomehana ʻia i 300 ℃ ma luna, ma hope o ke kuʻi ʻana i ka lāʻau wela e hiki ke loaʻa ka paʻakikī kūpono.
HOOLAHA OLA AWS E6010:
ʻO AWS E6010 kahi ʻano cellulose-Na type welding electrodes, kūikawā no DC.Hoʻohana ʻo ia i ka ʻenehana ʻē aʻe, loaʻa iā ia ka ARC hohonu hohonu, nā slags liʻiliʻi, maʻalahi ka wehe ʻana, kiʻekiʻe kuʻihao maikaʻi, nā waiwai hana nani.Hiki ke hoʻohana ʻia no ka wiliwili no nā kūlana a pau, kūlou i luna a lalo kūlana kuʻihao etc. hiki ke hiki i ka hopena o ka hoʻokumu ʻana o kekahi ʻaoʻao i nā ʻaoʻao ʻelua.
PALAPALA:
ʻO nā koʻokoʻo wiliwili AWS E6010 ka mea nui no ka hoʻopaʻa ʻana i ka paipu kila kalapona a i ʻole ka mea like, ke kākoʻo ʻana i ka weld / hoʻopiha weld / cosmetic weld no ka hale kila ma lalo.

NĀ MEA:
1. He mea maʻalahi ka weheʻana i ka wai, eʻoluʻolu e mālama i kahi maloʻo.
2. Pono ia e hoʻomehana i ka wā e haki ai ka pūʻolo a i ʻole ka makū, pono ka mahana wela ma waena o 70C a 80C, ʻo ka manawa hoʻomehana mai 0.5 a 1 hola.
3. Ke hoʻohana nei i nā electrodes wiliwili 5.0mm, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ke kiʻekiʻe kiʻekiʻe, haʻahaʻa haʻahaʻa, i mea e hoʻonui ai i ka hana kuʻi.
