He aha nā mea palekana e pono ai mākou e makaʻala i ka wā e wili ai?I kekahi manawa e alakaʻi kēia mau haʻalele i nā pōʻino, no laila e hoʻāʻo mākou e hana i nā pōʻino ma mua o ka pua ~ Ma muli o ke ʻano ʻokoʻa o nā wahi hana, a ua hana ʻia ka uila, ka māmā, ka wela a me nā lapalapa ahi i ka hana, aia nā pōʻino like ʻole. i ka hana wiliwili.
1, He mea maʻalahi ke kumu i nā pōʻino uila.
I ke kaʻina hana hoʻoheheʻe, no ka mea pono pinepine nā welders e hoʻololi i ka electrode i uhi ʻia a hoʻoponopono i ke ʻano o ka welding, pono lākou e hoʻopili pololei i nā electrodes a me nā pā polar i ka wā o ka hana, a ʻo ka mana welding maʻamau ʻo 220V / 380V.Ke hewa ka mea pale pale uila, ʻaʻole kūpono nā ʻatikala pale hana, a ke hana hewa nei ka mea hoʻohana, hiki ke kumu i nā pōʻino uila.I nā hihia o ke kuʻi ʻana i nā pahu metala, nā pipeline a i ʻole nā ​​​​wahi pulu, ʻoi aku ka nui o ka pilikia o ka haʻalulu uila.

2, He mea maʻalahi ke hana i nā ulia ahi a pahū.
No ka mea e hoʻopuka ʻia ka arc uila a i ʻole ka lapalapa ahi i ke kaʻina hana kuʻi, maʻalahi ke hana i ke ahi i ka wā e hana ai i nā wahi me nā mea hiki ke ahi.ʻOi aku ka maikaʻi ma nā wahi mea puhi ahi a pahū (me nā lua, nā ʻauwai, nā ʻauwaha, a me nā mea ʻē aʻe), ʻoi aku ka pōʻino i ka wā e hoʻopili ai i nā ipu, nā hale kiaʻi, nā pahu a me nā paipu i mālama ʻia i nā mea puhi ahi a pahū.

3, He mea maʻalahi ke kumu o ka electro-optic ophthalmia.
Ma muli o ke kukui ʻike ikaika ʻia a me ka nui o nā kukuna ultraviolet ʻike ʻole ʻia i hana ʻia i ka wā wili, he ikaika ikaika a hoʻopōʻino i nā maka o nā kānaka.ʻO ka hoʻomaʻamaʻa pololei ʻana i ka wā lōʻihi e hoʻoulu ai i ka ʻeha o ka maka, photophobia, waimaka, makaʻu i ka makani, a me nā mea ʻē aʻe, a maʻalahi ke alakaʻi i ka mumū o ka conjunctiva a me ka cornea (i ʻike mau ʻia ʻo electro-optic ophthalmia).
ʻO ke kukui arc i hana ʻia i ka kuʻi ʻana me ka pāhawewe māmā aia nā kukuna infrared, nā kukuna ultraviolet a me nā kukui ʻike ʻia, a he hopena radiation i ke kino kanaka.Loaʻa iā ia ka hana o ka radiation infrared, ka mea maʻalahi e alakaʻi i ka heatstroke i ka wā e hoʻopili ai i kahi kiʻekiʻe wela.Loaʻa i ka hana photochemical o nā kukuna ultraviolet, he mea pōʻino i ka ʻili o nā kānaka, a ma ka manawa like, ʻo ka lōʻihi o ka hoʻolaha ʻana i ka ʻili i hōʻike ʻia e hana pū ai ka ʻili ʻili.

4, He mea maʻalahi ka hāʻule ʻana mai kahi kiʻekiʻe.
E like me ka hana kūkulu ʻana, pono e piʻi pinepine nā welders i kiʻekiʻe no nā hana wili.Inā ʻaʻole kūpono nā ana no ka pale ʻana i ka hāʻule ʻana mai kahi kiʻekiʻe, ʻaʻole i hoʻohālikelike ʻia ka scaffolding a hoʻohana ʻia me ka ʻole o ka ʻae ʻia.Lawe i nā hana kaʻawale e pale aku i nā mea mai ke kuʻi ʻana i ka hana kea;ʻAʻole ʻike nā welders i ka palekana palekana pilikino, a ʻaʻole e komo i ka mahiole palekana a i ʻole ke kāʻei palekana i ka wā e piʻi ai.

5, Pono pinepine nā welders uila i ka ʻawaʻawa a me ka hoʻopaʻa ʻana i nā wahi i pani ʻia a i ʻole semi-pani ʻia e like me nā pahu metala, nā lako, nā paipu, nā hale kiaʻi a me nā pahu mālama no ka wili.Inā mālama ʻia, lawe ʻia a hana ʻia paha nā mea ʻawaʻawa a me nā mea ʻino a me nā kinoea inert, i ka wā ʻilihune ka hoʻokele hana, ʻaʻole i hoʻokumu ʻia nā ʻano pale, e maʻalahi ai ka make ʻana a i ʻole hypoxia a me ka ʻūhā o nā mea hana. , ʻoihana kemika a me nā ʻoihana ʻē aʻe.
