Paʻakikī i ka wiliwili ʻana i nā ʻāpana keleawe

Kaha keleaweHe maikaʻi ka uila a me ka thermal conductivity, akā nui nā pilikia paʻakikī i ke kaʻina hana kuʻi.ʻOi aku ka nui o ka conductivity thermal o ke kāʻei keleawe ʻulaʻula ma mua o ke kila.ʻOi aku ka nalo o ka welding wela, ʻoi aku ka nui o ke koʻikoʻi o loko, ka hopena i ka deformation kuʻihao a me nā pilikia kuʻihao ʻē aʻe.No laila, koi ʻia ka wela i ka wā wili.ʻO nā ala welding e pili ana i ka welding arc tungsten argon a me ka welding plasma.Eia kekahi, pono e hoʻokō ʻia ka preheating kūpono ma mua o ka welding.ʻAʻole pono e hoʻomaʻamaʻa mua ʻia kahi mea liʻiliʻi o ka brazing inā ʻaʻole i emi iho ma mua o ka ʻole.

ʻO ke ʻano o ke ʻano o ke kaula keleawe, ʻo ke kaʻina hana hoʻoheheʻe e hoʻopuka i ka uahi keʻokeʻo, ʻo ia hoʻi ʻoiai ʻaʻole he metala koʻikoʻi ka zinc, inā maikaʻi ʻole ka ea o ka wahi wili, hiki i ka uahi keʻokeʻo ke hoʻonāukiuki i ka ʻōnaehana hanu, ʻoi aku ka māmā, a inā paha ka mea hana. ʻaʻole ʻaʻahu i ka mask, ma hope o 30 mau minuke o ka hana, hāʻule lākou.ʻO ka lipine keleawe ulaula ka mea wiliwili, pono e like ka mea me ka mea kumu.No ka wili maʻamau wale nō, φ2.5-φ4 hiki ke hoʻohana ʻia ke kaula keleawe maʻamau.

He 70% wale nō o ka hao o ka ʻili o ka ʻili o ka wai.He mea maʻalahi ka hana ʻana i ka ʻauʻau hoʻoheheʻe ʻia i loko o ke kaʻina hana kuʻi, ʻaʻole e heheʻe ke aʻa.No ka hoʻoponopono ʻana i kēia pilikia, pono ʻoe e hoʻomaka me ke ʻano kuʻi ʻana like a laila hoʻopau.I ka hoʻomaka ʻana o ka welding, ʻaʻole kūpono ke kihi welding (10 ° -30 °), akā hiki i kēia kihi ke hoʻonā i ka pilikia hoʻoheheʻe o ka tungsten argon arc welding.

Inā makemake ʻoe e kiʻi i kahi weld kiʻekiʻe, mai makaʻu i ke kumukūʻai pipiʻi, ua ʻōlelo ʻia e hoʻohana i ke kinoea inert pale flux cored uea, e hana maikaʻi ka welding, akā kiʻekiʻe loa ke kumukūʻai, a me TIG welding. ʻaʻole kūʻai ʻia iho.ʻO ka pōkole, ʻo ka welding busbar copper strip he wela kiʻekiʻe, kahi kihi liʻiliʻi a me ka hana pale kiʻekiʻe.
