He ʻumi mau hana hoʻoheheʻe ʻana, e hoʻolauna ʻo XINFA i ʻumi mau ʻano hana wiliwili maʻamau, super intuitive animations, e aʻo pū kākou!
1.Electrode arc welding
Electrode arc welding ʻo ia kekahi o nā mākau maʻamau i haku ʻia e nā welders.Inā ʻaʻole ʻike ʻia nā mākau ma kahi, e loaʻa nā hemahema like ʻole i ka seam welded, e like me ka hōʻike ʻana ma ke wikiō aʻo aʻe.
2.Submerged arc welding
ʻO ka welding arc submerged he ʻano wili e hoʻohana ana i ke arc i kumu wela.Ma muli o ke komo hohonu ʻana o ka welding arc submerged, maikaʻi ka huahana a me ka maikaʻi o ka welding: no ka pale ʻana i ka pala, ʻaʻole i hoʻopili ʻia ka metala i hoʻoheheʻe ʻia me ka ea, a kiʻekiʻe ke kiʻekiʻe o ka hana mechanized, no laila kūpono ia. no ka wiliwili ʻana i nā wili lōʻihi o nā hale pā waena a me ka mānoanoa.
3.Argon arc wiliwili
Ke hāʻawi aku nei ʻo XINFA iā ʻoe i kekahi mau kaʻina no ka wili argon arc:
(1) Pono e oi pinepine ka nila tungsten.Inā ʻōpuʻu, ʻaʻole e noʻonoʻo a pua ke au.
(2) Inā pili ka mamao ma waena o ka nila tungsten a me ke kuʻi kuʻi ʻana, e pili pū ia, inā mamao loa, e mohala ke kukui arc, a i ka wā e pua ai, e ʻeleʻele ia, e lilo ka nila tungsten i ʻōhule. , a he ikaika nō hoʻi ka pāhawewe iā ia iho.ʻOi aku ka maikaʻi e pili kokoke.
(3) ʻO ka mana o ka hoʻololi ʻana he hana noʻeau, ʻoi aku hoʻi no ka wiliwili pā lahilahi, hiki ke kaomi a kaomi wale.ʻAʻole kēia he mīkini hoʻoheheʻe ʻakomi me ka neʻe ʻana a me ka hānai uea ʻakomi.
(4) No ka hānai ʻana i ka uea, he lima kona.Ua ʻoki ʻia ka uea kuʻi kiʻekiʻe mai ka papa 304 me kahi mīkini ʻā.Mai kūʻai i ka pūʻolo.ʻOiaʻiʻo, hiki iā ʻoe ke loaʻa nā mea maikaʻi ma nā wahi kūʻai nui.
(5) E ho'āʻo e hana ma lalo o nā kūlana ea, i hoʻolako ʻia me nā mīkina lima ʻili, nā lole, a me ka mask dimming aunoa.
(6) Pono e pale ʻia ke poʻo seramika o ka lama kuʻi mai ke kukui arc, ʻo ia hoʻi, ʻo ka huelo o ka lama kuʻi ʻana e pili kokoke i kou alo.
(7) Inā hiki iā ʻoe ke loaʻa ka ʻike a me ka hunch e pili ana i ka mahana, ka nui, a me ka hana hoʻololi o ka loko i hoʻoheheʻe ʻia, he loea kahiko ʻoe.
(8) E ho'āʻo e hoʻohana i nā koila tungsten melemele a keʻokeʻo paha, e koi ana i ka hana kiʻekiʻe.
4.Gas welding
ʻO ka hoʻoheheʻe kinoea (inoa piha: oxygen fuel gas welding, abbreviation: OFW) ʻo ia ka hoʻohana ʻana i ka lapalapa e wela ai ka metala a me ka uea kuʻi ma ka hui ʻana o ka mea hana metala e hoʻoheheʻe ʻia e hoʻokō i ke kumu o ka wili.ʻO nā kinoea hoʻohana maʻamau ka acetylene, ka ʻaila ʻaila liquefied a me ka hydrogen, a me nā mea ʻē aʻe.
5.Laser wiliwili
ʻO ka hoʻoheheʻe ʻana i ka laser kahi hana hoʻoheheʻe maikaʻi a pololei e hoʻohana ana i kahi kukuna laser kiʻekiʻe i ka ikehu ma ke ʻano he kumu wela.ʻO ka welding laser kekahi o nā mea koʻikoʻi o ka hoʻohana ʻana i ka ʻenehana hana ʻenehana laser.I ka makahiki 1970, ua hoʻohana nui ʻia no ka wiliwili ʻana i nā mea i hoʻopaʻa ʻia i ka paia a me ka wili haʻahaʻa.ʻO ke kaʻina hana hoʻoheheʻe ʻo ia ka hoʻoheheʻe wela, ʻo ia hoʻi, hoʻomaʻamaʻa ka radiation laser i ka ʻili o ka mea hana, a pālahalaha ka wela o ka ʻili i loko ma o ka lawe ʻana i ka wela.Ma ke kaohi ʻana i ka laulā, ka ikehu, ka mana kiʻekiʻe a me ka pinepine ʻana o ka pulse laser a me nā ʻāpana ʻē aʻe e hoʻoheheʻe i ka mea hana a hana i kahi wai hoʻoheheʻe kikoʻī.
6.Carbon dioxide pale kuʻihao
Ke manaʻo nei kekahi poʻe haku welders ʻo ka maʻalahi ka hoʻohana ʻana a me ke aʻo ʻana i ka wili kalapona i pale ʻia.ʻO ka mea maʻamau, inā ʻaʻole i hoʻopili ʻia kahi novice me ka welding, inā aʻo kahi haku iā ia no ʻelua a ʻekolu mau hola, hiki ke hoʻohana ʻia ka wili kūlana maʻalahi.
Aia kekahi mau mea nui i ke aʻo ʻana i ke kalapona i pale ʻia: nā lima paʻa, hiki ke hoʻololi i kēia manawa a me ka uila, hiki ke hoʻopaʻa ʻia ka wikiwiki o ka hoʻoheheʻe ʻana, nā ʻano, hiki ke hoʻomaʻamaʻa ʻia ma ka nānā ʻana i nā wikiō hou aʻe, a laila haku i ke kaʻina kuʻihao, hiki ke hoʻopaʻa ʻia ma mua o ka hapalua. ka hana i noi ai.
7.Friction welding
ʻO ka welding friction e pili ana i ke ʻano o ke kuʻi ʻana ma o ka hoʻohana ʻana i ka wela i hana ʻia e ka friction o ka ʻili pili o ka mea hana ma ke ʻano he kumu wela e hana ai ka mea hana i ka deformation plastic ma lalo o ke kaomi.
Ma lalo o ka hana o ke kaomi, ma lalo o ka hana o ka hoʻonui mau a i ʻole ka hoʻonui ʻana i ke kaomi a me ka torque, hoʻohana ʻia ka neʻe pili ma waena o ka hoʻopaʻa ʻana i ka hoʻopili ʻana i ka wela wela a me ka wela deformation plastic ma ka ʻili friction a me nā wahi a puni, i hiki ai i ka mahana piʻi aʻe nā wahi a puni I ka pae wela kokoke akā ʻoi aku ka haʻahaʻa ma mua o ka helu heheʻe, hoʻemi ʻia ke kūʻē deformation o ka mea, hoʻomaikaʻi ʻia ka plasticity, a haki ke kiʻi oxide ma ka interface.ʻO kahi ʻano kuʻihao paʻa e hoʻokō ai i ka wili.
ʻO ka hoʻoheheʻe ʻana i ka friction maʻamau i nā ʻanuʻu ʻehā: (1) ka hoʻololi ʻana o ka ikehu mechanical i ka ikehu wela;(2) deformation plastic o nā mea;(3) hoʻopaʻa i ke kaomi ma lalo o ka thermoplasticity;(4) diffusion intermolecular a me ka recrystallization.
8.Ultrasonic welding
ʻO ka welding ultrasonic ka hoʻohana ʻana i nā hawewe haʻalulu kiʻekiʻe e hoʻouna i nā ʻili o nā mea ʻelua e welded.Ma lalo o ke kaomi, ʻānai ʻia nā ʻili o nā mea ʻelua i kekahi i kekahi e hana i ka hui ʻana ma waena o nā papa molekala.ʻO nā ʻāpana nui o kahi ʻōnaehana hoʻoheheʻe kani ultrasonic e komo pū me ka ultrasonic generator/transducer/horn/weld head triplet/mold and frame.
9.Soldering
ʻO Brazing ka hoʻohana ʻana i kahi mea metala me kahi mea hoʻoheheʻe haʻahaʻa ma mua o ka metala kumu e like me ka solder, hoʻomehana i ka weld a me ka solder i kahi mahana i ʻoi aku ka kiʻekiʻe ma mua o ka helu heheʻe o ka mea kūʻai aku a haʻahaʻa ma mua o ka wela heheʻe o ka metala kumu, hoʻohana i ka wai. solder e hoʻomaʻemaʻe i ke kumu metala, e hoʻopiha i ke āpau ma waena o nā hui a ʻO ke ʻano o ka interdiffusion me ka metala kumu e ʻike ai i ka pilina o ka weldment.He liʻiliʻi ka deformation brazing, a maʻalahi a nani ka hui.He kūpono ia no ka wiliwili pololei, paʻakikī a me nā ʻāpana i haku ʻia me nā mea like ʻole, e like me nā pā hale honeycomb, turbine blades, nā mea hana paʻa paʻa a me nā papa kaapuni paʻi.Ma muli o ka wela welding, hiki ke hoʻokaʻawale ʻia ka brazing i ʻelua mau ʻāpana.Inā ʻoi aku ka haʻahaʻa o ka wela wela ma mua o 450 ° C, ua kapa ʻia ʻo ia ʻo soldering palupalu, a inā ʻoi aku ka kiʻekiʻe ma mua o 450 ° C, ua kapa ʻia ʻo ia ka brazing paʻakikī.
