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 nui o ka nalowale ʻana o ka welding wela, ʻoi aku ka nui o ke koʻikoʻi o loko, ka hopena i ka deformation kuʻihao a me nā pilikia wili.No laila, koi ʻia ka ʻike wela i ka wā wili.ʻO nā ʻano welding e pili ana i ka welding arc tungsten argon a me ka welding plasma.Eia kekahi, pono e hana ʻia ka preheating kūpono ma mua o ke kuʻi ʻana.ʻAʻole pono e hoʻomaʻamaʻa mua ʻia kahi mea liʻiliʻi o ka brazing inā ʻaʻole ia e emi iho ma mua o ka zero.

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 ʻo ka zinc he metala kaumaha, inā maikaʻi ʻole ka ventila o ka wahi wiliwili, hiki i ka uahi keʻokeʻo ke hoʻonāukiuki i ka ʻōnaehana hanu, ʻoi aku ka māmā, a inā ʻaʻole i uhi ka mea hana i ka pale, 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 wai.He mea maʻalahi ka hana ʻana i ka wai 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 kuʻihao like a laila hoʻopau.I ka hoʻomaka ʻana o ka welding, ʻaʻole kūpono ke kihi welding (10 ° -30 °), akā hiki i kēia kihi ke hoʻoponopono i ka pilikia hoʻoheheʻe o ka tungsten argon arc welding.

Inā makemake ʻoe e kiʻi i kahi weld kiʻekiʻe, mai makaʻu ʻoe 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 ʻaʻole maʻalahi ke kuʻi ʻana iā ia iho.ʻO ka pōkole, ʻo ka welding busbar copper strip he wela kiʻekiʻe, kahi kihi liʻiliʻi a me ka hana pale kiʻekiʻe.
