He aha ka Oxy-Acetylene Hardfacing Method

undefined


ʻO ka hoʻomaka ʻana o ka welding Oxy-Acetylene

Nui nā ʻano kaʻina hana kuʻikuʻi no ka hoʻohui ʻana i ka metala. Mai ka welding flux-cored i ka welding GTAW/TIG, i ka welding SMAW, i ka welding GMAW/MIG, e lawelawe ana kēlā me kēia kaʻina wili i kahi kumu kikoʻī e pili ana i ke kūlana a me nā ʻano mea e welded ʻia.


ʻO kekahi ʻano hoʻoheheʻe ʻana he oxy-acetylene welding. ʻIke ʻia ʻo ka welding oxy-fuel, ʻo ka welding oxy-acetylene kahi kaʻina hana e hilinaʻi ana i ka puhi ʻana o ka oxygen a me kahi kinoea wahie, maʻamau acetylene. Hiki paha i ka hapa nui o ʻoukou ke lohe i kēia ʻano wili i kapa ʻia ʻo "gas welding."


ʻO ka maʻamau, hoʻohana ʻia ka wili kinoea no ka wili ʻana i nā ʻāpana metala lahilahi. Hiki i nā kānaka ke hoʻohana i ka welding oxy-acetylene no nā hana hoʻomehana, e like me ka hoʻokuʻu ʻana i nā bolts maloʻo a me nā nati a me ka hoʻomehana ʻana i nā mea kaumaha no nā hana wili a palupalu.


Pehea e hana ai ka welding oxy-acetylene?

Hoʻohana ʻo Oxy-acetylene welding i ka wela wela, wela wela nui i hana ʻia ma ke puhi ʻana i ke kinoea wahie (ʻoi loa ka acetylene) i hui pū ʻia me ka oxygen maʻemaʻe. Hoʻoheheʻe ʻia ka mea kumu me ke koʻokoʻo hoʻopiha me ka hoʻohana ʻana i kahi lapalapa mai ka hui pū ʻana o ke kinoea oxy-fuel ma ka piko o ka lama wili.


Mālama ʻia ke kinoea wahie a me ke kinoea oxygen i loko o nā pahu kila i kaomi ʻia. Hoʻemi nā mea hoʻoponopono i loko o ka cylinder i ke kaomi kinoea.


Ke kahe nei ke kinoea ma o na paipu hikiwawe, me ka welder e hoomalu ana i ke kahe ma o ka lama. Hoʻoheheʻe ʻia ke koʻokoʻo hoʻopiha me ka mea kumu. Eia nō naʻe, hiki ke hoʻoheheʻe ʻia ʻelua ʻāpana metala me ka ʻole o ke koʻokoʻo hoʻopiha.


He aha nā ʻokoʻa nui ma waena o ka welding oxy-acetylene a me nā ʻano welding ʻē aʻe?


ʻO ka ʻokoʻa nui ma waena o ka welding oxy-fuel a me nā ʻano wili arc e like me SMAW, FCAW, GMAW, a me GTAW ke kumu wela. Hoʻohana ʻo Oxy-fuel welding i ka lapalapa e like me ke kumu wela, a hiki i nā mahana a hiki i 6,000 degere Fahrenheit.


Hoʻohana ka wiliwili ʻana i ka uila ma ke ʻano he kumu wela, a hiki i nā mahana ma kahi o 10,000 F. ʻO kēlā me kēia ʻano, makemake ʻoe e makaʻala a palekana i ka wā e wiliwili ai i nā ʻano wela wela.

I nā lā mua o ka wiliwili, hoʻohana ʻia ka wili oxyfuel e wili i nā papa mānoanoa. I kēia manawa, hoʻohana wale ʻia ia ma ka metala lahilahi. Ke hoʻololi nei kekahi mau kaʻina hana wili arc, e like me GTAW, i ke kaʻina hana wili oxy-fuel ma nā metala lahilahi.


Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.


E HOOHUNA MAI I KA LEKA
E ʻoluʻolu e leka a e hoʻi mākou iā ʻoe!
