Paʻakikī ka wili keleawe, hiki i nā mīkini wili maʻamau ke mālama iā ia? Pono ʻoe i kekahi ʻenehana kūikawā?

I. He Paʻakikī nā Mekini Welding maʻamau i ka hana, a maopopo ko lākou mau hemahema.

1. Mīkini wiliwili lima maʻamau: ʻaneʻane ʻole
• Ke hilinaʻi nei kēia ʻano mīkini wiliwili i ka wela i hana ʻia e ka puhi ʻana o ke koʻokoʻo wili. ʻAʻole lawa ka hoʻokomo wela e hoʻoheheʻe ma o nā mea keleawe. Eia kekahi, ʻaneʻane ʻaʻohe lāʻau welding i hoʻolālā ʻia no nā mea keleawe ma ka mākeke. Inā hoʻohana ikaika ʻoe i nā koʻokoʻo wiliwili ʻē aʻe, ʻaʻole paʻa a piha paha ka hili weld i ka pala. Hiki ke hoʻohana wale ʻia no ka hoʻopaʻa ʻana i kahi puka liʻiliʻi. No ka wili keleawe kūpono, ʻaʻole hiki ke hilinaʻi ʻia.
2. Mīkini wiliwili ʻo DC TIG: kaupalena ʻia i ke keleawe maʻemaʻe lahilahi
• ʻAʻole hiki i ka mīkini wiliwili DC TIG ke wiliwili i ke keleawe maʻemaʻe me ka mānoanoa o 1-3 mm, e like me nā mea hoʻopili keleawe liʻiliʻi. Eia nō naʻe, nui nā pilikia: nele i ka hana hoʻomaʻemaʻe cathode, ʻo ia hoʻi ʻaʻole hiki iā ia ke wehe i ke kiʻi oxide ma ka ʻili o nā mea keleawe, e maʻalahi ai ka paʻa ʻana o ka slag i ka weld seam. ʻAʻole pololei ka mana hoʻokomo wela. I ka wā e wiliwili ai i nā mea keleawe mānoanoa, e 'weliweli ʻia.' ʻAʻole hiki iā ia ke wili i ke keleawe (e mahuʻi maʻalahi ka zinc i loko o ke keleawe i nā wela kiʻekiʻe, e lilo ai ke wili weld i mea palupalu).
3. MIG Welding Machine maʻamau: Kūleʻa i ka Burnthrough a me nā pilikia ʻē aʻe
• Ke hoʻoheheʻe ʻia nā mea keleawe me kahi mīkini wili MIG maʻamau, koi ʻia kahi au nui e hoʻoheheʻe i nā mea keleawe. Eia naʻe, hiki i ke au kiʻekiʻe ke puhi maʻalahi ma o nā mea keleawe me ka paia lahilahi. Eia kekahi, ʻo ka hoʻohana ʻana i ke kinoea argon maʻemaʻe no ka pale ʻana ʻaʻole kūpono i ka pale ʻana i ka oxidation a me ka absorption kinoea o nā mea keleawe. I ka wā e wili ai i ke keleawe, ua koʻikoʻi ka evaporation o ka zinc. ʻAʻole kēia e hoʻohaumia wale i ke kaiapuni akā e hōʻemi ana i ka ikaika o ka weld seam, ʻaʻole e hoʻokō i nā koi maikaʻi.

I ka hōʻuluʻulu manaʻo, hiki i nā mīkini wiliwili maʻamau ke lawelawe i kahi liʻiliʻi o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa wili keleawe maʻemaʻe. No ka wili pono ʻana i nā mea keleawe mānoanoa, keleawe, a me nā ʻāpana keleawe me ka ikaika a me nā koi conductivity uila, pono nā mea ʻoihana e like me nā mīkini wiliwili wahi, nā mīkini welding laser, a me nā mīkini wiliwī laser robotic, me nā kaʻina hana kūikawā.

II. ʻOi aku ka kūpono o nā lako ʻoihana, a ʻo ke koho kūpono e pili ana i ke ʻano

1. Mīkini Welding Spot: ʻO ka koho mua no ka hui pū ʻana o nā mea keleawe i uhi ʻia i ka paia
• Ke hilinaʻi nei ka mīkini wiliwili wahi keleawe i ke kaomi o nā electrodes a hoʻohana i ke kūpaʻa pili i ka wela a hoʻoheheʻe i nā mea keleawe kūloko e hana i nā wahi weld. ʻO kona pōmaikaʻi ka wikiwiki; ʻO kēlā me kēia helu weld e lawe wale i ka 0.1-1 kekona. He kūpono loa ia no ka hoʻopili ʻana i nā mea keleawe i hoʻopaʻa ʻia i ka paia lahilahi (0.1-2 mm), e like me ka hoʻopili ʻana o nā alakaʻi keleawe i nā mea uila a me ka hui ʻana o nā ʻāpana keleawe liʻiliʻi.
• Eia naʻe, he mea nui e hoʻomaopopo pono ʻoe e koho i kahi mīkini wiliwili keleawe i hoʻolaʻa ʻia. No ka mea he kiʻekiʻe ka conductivity uila o ke keleawe, pono ia i nā ʻāpana kuʻi o ka manawa kiʻekiʻe a me ka manawa pōkole e pale aku i ka hoʻopunipuni hoʻopunipuni. Pono nā electrodes i ka mālama mau ʻana e pale i ka oxidation a me ka ʻaʻahu mai ka hoʻopilikia ʻana i ka maikaʻi wili.
2. Laser Welding Machine: Pono no ka High-Precision Copper Weld
• Hoʻohana ka mīkini hoʻoheheʻe laser i kahi kukuna laser ikaika nui e hoʻoheheʻe i nā mea keleawe. He liʻiliʻi loa ka ʻāpana wela, a hiki iā ia ke hoʻomalu pono i ka weld seam. He laumania ka hopena weld seam a aneane ʻaʻole pono i ka hoʻoponopono hope. Loaʻa iā ia kahi ākea ākea a hiki ke weld i ke keleawe maʻemaʻe a me ke keleawe me nā mānoanoa mai 0.05 a 6 mm. He kūpono ia no nā hiʻohiʻona me nā koi kiʻekiʻe a me nā hiʻohiʻona hiʻohiʻona, e like me nā ʻāpana keleawe i nā mīkini uila pololei a me nā mea hoʻohui keleawe i nā mea lapaʻau.
• I ka wā e hoʻopaʻa ai i nā mea keleawe, pono ia e koho i ka mīkini welding laser me ka hana pulse, hiki ke hoʻemi i ka hoʻokomo wela a pale i ka deformation o nā mea keleawe. I ka manawa like, pono e hoʻohana ʻia me ka pale kino argon e pale i ka oxidation a me ka absorption kinoea, e hōʻoia i ka maikaʻi o ka weld seam.
3. Robotic Laser Welding Machine: ʻO ke koho i makemake ʻia no ka wili keleawe maʻamau maʻamau
• ʻO ka robotic laser welding machine ka hui pū ʻana o ka mīkini welding laser a me ka lima robotic, hiki ke hoʻokō i ka welding automated a hiki ke hana mau no 24 mau hola. He kūpaʻa kona kuʻi ʻana a ʻaʻole e hoʻopilikia ʻia e nā ʻokoʻa hana kanaka. He kūpono ia no ka wili keleawe nui, e like me ke kuʻi ʻana o nā kaula keleawe keleawe i ka ʻoihana kaʻa a me ka hui ʻana o nā pahu keleawe i nā lako mana.
• Loaʻa iā ia kahi ʻano like o ka hoʻololi ʻana i nā mīkini welding laser ma ke ʻano o ka mānoanoa keleawe a hiki ke hoʻopaʻa ʻia i ka wiliwili trajectory paʻakikī, e like me ka circumferential weld seams o nā ʻāpana keleawe ʻole. He kūpono loa ia no nā ʻoihana me ka hana nui, hiki ke hoʻomaikaʻi nui i ka pono a hoʻemi i nā kumukūʻai hana.

III. Pono nā kaʻina hana kūikawā no ka welding keleawe, a ʻekolu mau ʻanuʻu e hōʻoia i ka maikaʻi

1. Ma mua o ka wiliwili ʻana: ʻO ka hoʻomaʻemaʻe ʻana ke kī
• ʻO ka ʻaila a me ka oxide film ma luna o ka ʻili o nā mea keleawe he mau pōʻino wili a pono e hoʻomaʻemaʻe pono ʻia. E hoʻohana i ka acetone a i ʻole ka waiʻona no ka wehe ʻana i ka aila, ka pepa one i ka poli a i ʻole ka sulfuric acid e wehe i ke kiʻi oxide mai ke keleawe maʻemaʻe, a me nā mea hoʻomaʻemaʻe kūikawā e mālama i ke keleawe. Inā wili nā mea keleawe mānoanoa (ʻoi aku ma mua o 8 mm), e wela mua i ka 200-400°C ma mua o ka wili ʻana e hoʻolohi i ka nalowale ʻana o ka wela a pale i ka hoʻopaʻa ʻole ʻana.
2. I ka wā welding: Pono e kau ʻia nā ʻāpana a me ka pale
• E hoʻoponopono i nā palena e like me nā mea hana a me ke ʻano o nā mea keleawe. No ka laʻana, i ka wā e hoʻohana ai i ka mīkini welding laser e wili i 3 mm keleawe maʻemaʻe, pono e hoʻoponopono ʻia ka nui o ka ikehu i ka pae kūpono. Pono ke kinoea pale. E hoʻohana i ka hui ʻana o ka argon a me ka helium no ka wili keleawe maʻemaʻe, a me ka hui ʻana o ka argon a me 5% -10% nitrogen no ka hoʻoheheʻe keleawe, me kahi kahe kahe e hoʻomalu ʻia ma 20-25 L / min e pale i ka oxidation a me ke kinoea absorption.
3. Ma hope o ka wiliwili ʻana: Pono ka hoʻoluʻu mālie a me ka nānā ʻana
• Ma hope o ke kuʻi ʻana, e uhi i ka weld seam me ka lole asbestos e ʻae i ka mea keleawe e hoʻomaha mālie, e hōʻemi i ke kaumaha o loko a pale i ka deformation a me ka māhā. No nā ʻāpana keleawe mānoanoa, hiki ke hoʻopau i ke kaumaha haʻahaʻa (250-300°C no 1 hola). ʻO ka hope, e nānā i ka weld seam e nānā i ka porosity, nā māwae, a me ka hoʻāʻo uila e like me ka mea e pono ai e hōʻoia i ka maikaʻi e kūpono i nā kūlana.

Inā loaʻa iā ʻoe nā koi mīkini wili, e ʻoluʻolu e kelepona iā Ms. Zhao
