1. Kaʻina hana
ʻO ka welding arc electrode he ʻano hana kuʻihao me ka hoʻohana ʻana i ke koʻokoʻo wili lima.ʻO ka hōʻailona hōʻailona E no ka welding arc electrode a me ka kaha helu 111.
ʻO ke kaʻina hana hoʻoheheʻe o ka welding arc electrode: i ka wā e wili ai, lawe ʻia ke koʻokoʻo kuʻi i ka pilina me ka mea hana ma hope koke o ke kaapuni pōkole, e hoʻā ana i ke arc.ʻO ka wela kiʻekiʻe o ke arc e hoʻoheheʻe hapa i ka electrode a me ka mea hana, a me ka hoʻoheheʻe ʻana o ke kumu i hoʻoheheʻe ʻia i ka papa hana i hoʻoheheʻe ʻia ma ke ʻano o kahi kulu hoʻoheheʻe ʻia, i hui pū ʻia e hana i kahi wai hoʻoheheʻe.Hoʻopuka ka welding electrode flux i kahi nui o ke kinoea a me ka slag wai i ka wā o ka hoʻoheheʻe ʻana, a ʻo ke kinoea i hana ʻia e hoʻopiha i ke arc a me nā wahi a puni o ka loko i hoʻoheheʻe ʻia, e pāʻani ana i kahi kuleana i ka hoʻokaʻawale ʻana i ka lewa e pale i ka metala wai.He liʻiliʻi ka liʻiliʻi o ka wai, i loko o ka wai hoʻoheheʻe e lana mau ana, uhi ʻia i ka metala wai ma luna, e pale i ka hana o ka metala wai.I ka manawa like, ka flux ili hehee ai kinoea, slag a me ka hehee ana i ka weld kumu, ka workpiece ka moʻo o ka metallurgical reactions e hōʻoia i ka hana o ka weld i hanaia.
2. ʻO nā mea maikaʻi o ka welding arc electrode
1) Mea maʻalahi, mālama maʻalahi.ʻO nā mīkini hoʻoheheʻe AC a me DC i hoʻohana ʻia no ka welding arc electrode he mea maʻalahi a ʻaʻole koi i nā mea kōkua paʻakikī no ka hana ʻana o ke koʻokoʻo welding, a pono e hoʻolako ʻia me nā mea kōkua maʻalahi.He mea maʻalahi kēia mau mīkini wiliwili i ke ʻano, maʻalahi a maʻalahi hoʻi e mālama, a haʻahaʻa ka hoʻopukapuka ʻana i ke kūʻai ʻana i nā mea hana, ʻo ia kekahi o nā kumu o kāna noi ākea.
2) ʻAʻole pono ka pale kinoea kōkua, ʻaʻole hāʻawi wale ke koʻokoʻo hoʻopihapiha i ka metala hoʻopihapiha, akā hiki nō hoʻi ke hana i ke kinoea pale e pale aku ai i ka wai i hoʻoheheʻe ʻia a me ka weld mai ka oxidation i ka wā o ka welding, a loaʻa iā ia kahi kūpaʻa makani ikaika.
3) Ka hana maʻalahi a me ka hoʻololi ikaika.He kūpono ka wiliwili lāʻau lāʻau no ka wiliwili ʻana i nā ʻāpana hoʻokahi a i ʻole nā pūʻulu liʻiliʻi o nā huahana, pōkole a maʻamau ʻole, aia ma kahi ākea a me nā wili wili ʻē aʻe ʻaʻole maʻalahi ke hoʻokō mechanized welding.Hiki ke hoʻokō ʻia ka welding ma nā wahi a pau e hiki ai ke koʻokoʻo wiliwili, me ka hiki ke komo maikaʻi a me ka hana maʻalahi loa.
4) Ka laulā o nā noi, kūpono no ka wiliwili ʻana i ka hapa nui o nā metala ʻoihana a me nā alloys.E koho i ke koʻokoʻo kuʻi kūpono ʻaʻole hiki ke weld wale i ke kila kalapona, ke kila haʻahaʻa haʻahaʻa, akā ke kila kila kiʻekiʻe a me nā metala non-ferrous;ʻAʻole hiki ke weld wale i ka metala like, akā hiki ke weld i nā metala like ʻole, akā hoʻolei pū i ka hoʻoponopono wili hao a me nā mea metala like ʻole e like me ka overlay welding.
3. nā hemahema o ka wiliwili electrode arc
1) He kiʻekiʻe nā koi ʻenehana hana welders, nā koina aʻo ʻana i nā welders.ʻO ka maikaʻi o ka welding arc welding ma kahi o ke koho ʻana i nā electrodes welding kūpono, nā ʻāpana kaʻina hana welding a me nā mea hana welding, ka mea nui e nā welders e hana ana i nā ʻenehana a me ka ʻike e hōʻoia i ka maikaʻi o ka welding arc welding i kahi kikoʻī i hoʻoholo ʻia e nā welders e hana ana. ʻenehana.No laila, pono e hoʻomaʻamaʻa pinepine ʻia nā welders, nui nā kumukūʻai aʻo e pono ai.
2) Nā kūlana hana maikaʻi ʻole.Ke hilinaʻi nui nei ka wiliwili lāʻau lāʻau i ka hana lima o nā welders a me ka nānā maka e hoʻopau i ke kaʻina hana, ka ikaika o ka hana a nā welders.A i nā manawa a pau i ka wela wela a me ka ʻawaʻawa ʻawaʻawa, ʻilihune nā kūlana hana, no laila e hoʻoikaika i ka pale hana.
3) Haʻahaʻa hana pono.ʻO ka welding rod arc welding e hilinaʻi nui i ka hana lima, a me nā ʻāpana kaʻina hana e koho i kahi liʻiliʻi.Eia kekahi, pono e hoʻololi pinepine ʻia ka electrode welding, a pono e hoʻomaʻemaʻe pinepine ʻia ka hoʻomaʻemaʻe ʻana i ka hoʻomaʻemaʻe ʻana i ka welding, ke hoʻohālikelike ʻia me ka welding maʻalahi, haʻahaʻa ka huahana welding.
4) ʻAʻole pili i nā metala kūikawā a me ka hoʻoheheʻe ʻana i ka pā lahilahi.No nā metala ikaika a me nā metala insoluble, no ka mea, ua maʻalahi kēia mau metala i ka pollution oxygen, ʻaʻole lawa ka pale o ka electrode e pale ai i ka oxidation o kēia mau metala, ʻaʻole maikaʻi ka hopena pale, ʻaʻole kūpono ka maikaʻi o ka welding i nā koi, no laila ʻaʻole hiki iā ʻoe ke hoʻohana i ka welding arc electrode.ʻAʻole hiki ke hoʻopaʻa ʻia nā metala hoʻoheheʻe haʻahaʻa a me kā lākou mau mea hoʻoheheʻe e ka electrode arc welding no ka mea he kiʻekiʻe loa ka mahana o ke arc no lākou.
4. Laulā noi
1) E pili ana i ka hoʻopili ʻana i nā kūlana āpau, ka mānoanoa mea hana ma luna o 3mm
2) Weldable metala laula: nā metala i hiki ke welded e like me carbon kila, haʻahaʻa hao kila, kuhiliʻole kila, wela wela, keleawe a me kona mau ala;ʻo nā metala hiki ke wili ʻia akā hiki ke hoʻomaʻamaʻa ʻia, ma hope o ka wela a i ʻole nā mea ʻelua me ka hao hoʻolei, ke kila ikaika kiʻekiʻe, ke kila kinai ʻia, etc.;nā metala hoʻoheheʻe haʻahaʻa ʻaʻole hiki ke hoʻopaʻa ʻia e like me Zn/Pb/Sn a me kāna mau ʻāpana, nā metala hiki ʻole ke hoʻoheheʻe ʻia e like me Ti/Nb/Zr, etc.
3) ʻO ke ʻano huahana kūpono loa a me ke ʻano o ka hana ʻana: nā huahana me nā hale paʻakikī, me nā kūlana spatial like ʻole, nā welds ʻaʻole i maʻalahi i ka mechanized a i ʻole automated;kūʻai hoʻokahi a i ʻole nā huahana welded haʻahaʻa a me nā keʻena hoʻonohonoho a hoʻoponopono paha.
