Pehea e weld kila galvanized?
2024-12-16
He aha ke kila galvanized?
ʻO ka Galvanizing kahi lāʻau anti-corrosion e uhi ana i ke kila me kahi ʻāpana o ka metala zinc e pale iā ia mai ka ʻino. Kūpaʻa loa ʻo Zinc i ka corrosion a hana ia me ke kila e hana i kahi papa pale, ʻike ʻia ʻo ka zinc-iron alloy layer, e pale ana i ke kila mai ka pōʻino oxidative. No kēia kumu,kila kilahoʻohana nui ʻia i ke kūkulu ʻana, nā kaʻa, nā alahaka a me nā māla ʻē aʻe.
ʻO nā ʻano hana kuʻihao maʻamau maʻamau
1. Kuʻi kinoea
ʻO ka hoʻoheheʻe kinoea kahi ʻano o ka hoʻoheheʻe ʻana i nā ʻāpana kila galvanized me ka hoʻohana ʻana i ka wela kiʻekiʻe i hana ʻia e ka hoʻopau ʻana i ke kinoea me ka ʻole o kahi kumu mana o waho, a me ka hoʻohana ʻana iā lākou me ka hoʻohana ʻana i nā mea wili. He kūpono kēia ʻano no nā lau kila GI ʻoi aku ka mānoanoa.
2. ʻAha kuʻihao
ʻO ka hoʻoheheʻe ʻana he ala ia e hoʻoheheʻe ai i nā ʻāpana kila me ka hoʻohana ʻana i ka hoʻomehana arc uila a laila wili iā lākou me ka hoʻohana ʻana i nā mea wili. Pono kēia ʻano e ʻokiʻoki i kahi wahi o ka papa galvanized ma mua o ke kuʻi ʻana.
3. Kuʻiʻo arc submerged
ʻO ka wiliwili arc submerged he ʻano like ʻole o ka welding arc pale kinoea. Hoʻohana ʻo ia i kahi noho electrode uea kila a me kahi puʻupuʻu i hoʻopaʻa paʻa ʻia ma nā ʻaoʻao ʻelua o ka hui paipu e uhi i ke arc i ka weld. Hiki i kēia ʻano hana ke pale aku i ka papa galvanized ma mua o ka wili arc.
ʻO nā kumu e pōʻino maʻalahi ai ka papa galvanized i ka wā wili
I ka wā e wiliwili ai i nā pale kila, ua maʻalahi ka pōʻino o ka papa galvanized ma muli o nā kumu e like me ke kiʻekiʻe o ka wela a me ka hopena oxidation i ka wā o ke kaʻina hana.
Eia kekahi, i loko o nā kaʻina hana wiliwili hoʻokomo wela e like me ka hoʻoheheʻe ʻana i ka arc a me ka welding arc, ua maʻalahi ke koena o ka wai zinc i ka wā o ka hoʻomehana ʻana o ka pā kila, e hoʻopiʻi ana i nā ʻokoʻa o nā wahi ʻeleʻele, nā kiko keʻokeʻo a me nā mea puhi zinc.
Nā ʻenehana welding e pale aku i ka pōʻino i ka papa galvanized
1. Hoʻomāhana mua
Hiki i ka preheating ke hana i ka zinc-aluminum alloy o ka zinc coating ma ka ʻili o ka pā kila e hoʻopuehu i lalo, e hana i kahi hui paʻa me ka substrate, a pale i ka pōʻino o ka uhi zinc ma ka wili wela.
2. E koho i ke au wiliwili kūpono a me ka volta
Hiki i ke au kūpono a me ka volta ke hoʻomalu pono i ka wela welding a pale aku i ka pōʻino o ka papa galvanized. I ka manawa like, pono e koho ʻia nā ʻokoʻa welding a me nā voltages no nā pā kila galvanized o nā mānoanoa like ʻole a me nā kikoʻī.
3. E hoʻohana i nā mea wili kūikawā
I kēia manawa, aia kekahi mau mea hoʻoheheʻe i hoʻolālā kūikawā ʻia no ka hoʻoheheʻe ʻana i ke kila kila ma ka mākeke, hiki ke hoʻomaikaʻi maikaʻi i ka maikaʻi o ka welding a me ka maikaʻi me ka pale ʻana i ka pōʻino i ka papa galvanized.
4. E koho i ke kaʻina wiliwili kūpono
No nā papa kila galvanized o nā kikoʻī like ʻole a me nā mea waiwai, pono e koho ʻia nā kaʻina hana kuʻi kūpono, e like me MIG welding, TIG welding, cladding welding, etc.
5. E hoʻoikaika i ka nānā ʻana i ka maikaʻi
ʻO nā hanana kūponoʻole i ke kaʻina hana kuʻi, e like me ke ahi zinc, nā wahiʻeleʻele, nā wahi keʻokeʻo, a me nā mea'ē aʻe, pono e mālamaʻia a hoʻololi i ka manawa e hōʻoia i ka maikaʻi o ka welding.
Ka hopena
I ka hōʻuluʻulu manaʻo, no ka hoʻomaʻamaʻa kuʻi ʻana o nā ʻāpana kila, ke koho ʻana i nā ʻano kuʻihao kūpono a me ka hoʻomaʻamaʻa ʻana i nā mākau e pale ai i ka hoʻopōʻino ʻana o ka papa galvanized hiki ke hoʻomaikaʻi i ka maikaʻi a me ka maikaʻi o ka welding, a ma ka manawa like e hoʻolōʻihi i ke ola lawelawe o nā pale kila galvanized. .
I ka hana maoli, pono e uku ʻia i nā pilikia e like me ke koho ʻana i nā mea, ka mālama ʻana i ka mahana, a me ka hoʻoikaika ʻana i ka nānā ʻana i ka maikaʻi e hōʻoia i ka hopena welding a me ka palekana.
