ʻO ka welding, i ʻike ʻia ʻo ka welding a i ʻole ka welding, he kaʻina hana a me ka ʻenehana e hoʻohana ana i ka wela, ke kiʻekiʻe kiʻekiʻe a i ʻole ke kaomi kiʻekiʻe e hoʻohui i ka metala a i ʻole nā mea thermoplastic e like me ka plastic. Wahi a ke kūlana o ka metala i ke kaʻina hana a me nā ʻano o ke kaʻina hana, hiki ke hoʻokaʻawale ʻia nā ʻano welding i ʻekolu mau ʻāpana: fusion welding, pressure welding a brazing.
Hoʻoheheʻe Fusion - hoʻomehana i nā mea hana e hoʻohui ʻia e hoʻoheheʻe ʻia lākou e lilo i loko i hoʻoheheʻe ʻia, a maʻalili a paʻa ka wai hoʻoheheʻe ma mua o ka hui ʻana. Inā pono, hiki ke hoʻohui ʻia nā mea hoʻopihapiha e kōkua
1. Hoʻopili laser
Hoʻohana ka hoʻoheheʻe laser i ka kukuna laser i hoʻopaʻa ʻia ma ke ʻano he kumu ikehu e hoʻopā i ka mea hana me ka wela no ka wili. Hiki iā ia ke weld i nā mea metala like ʻole a me nā mea metala ʻole e like me ke kila kalapona, ke kila silika, ka aluminika a me ka titanium a me kā lākou mau ala, tungsten, molybdenum a me nā metala refractory a me nā metala like ʻole, a me nā seramika, aniani a me nā plastics. I kēia manawa, hoʻohana nui ʻia i nā mea uila, mokulele, aerospace, nuclear reactors a me nā kula ʻē aʻe. Loaʻa i ka welding laser nā ʻano penei:
(1) He kiʻekiʻe ka nui o ka ikehu o ka kukuna laser, pōkole loa ke kaʻina hana hoʻomehana, liʻiliʻi nā hui solder, haiki ka wahi i hoʻopili ʻia i ka wela, liʻiliʻi ka deformation kuʻi, a kiʻekiʻe ka kiko o ka weldment;
(2) Hiki iā ia ke weld i nā mea paʻakikī e hoʻopaʻa ʻia e nā ʻano hana kuʻuna maʻamau, e like me ka welding metala refractory e like me tungsten, molybdenum, tantalum, a me zirconium;
(3) Hiki ke welded i nā metala non-ferrous i ka lewa me ka ʻole o ke kinoea pale;
(4) He paʻakikī nā mea hana a he kiʻekiʻe ke kumukūʻai.
2. Kuʻi kinoea
Hoʻohana nui ʻia ka wili kinoea i ka wiliwili ʻana i nā papa kila lahilahi, nā mea hoʻoheheʻe haʻahaʻa (nā metala non-ferrous a me kā lākou mau ʻāpana), nā ʻāpana hao a me nā mea paʻa paʻa paʻa, a me ka hoʻoponopono ʻana i nā ʻāpana a me nā ʻāpana i ʻoki ʻia, ka hoʻoponopono ʻana i ke ahi. deformation, etc.
3. ʻAha kuʻihao
Hiki ke hoʻokaʻawale ʻia i ka welding arc manual a me ka welding arc submerged
(1) Hiki i ka wili lima arc ke hana i ka wiliwili kūlana lehulehu e like me ka wiliwili palahalaha, ka wiliwili kūwae, ka wiliwili ʻana a me ka wiliwili ma luna. Eia hou, no ka mea, hiki ke hoʻohana ʻia nā mea hoʻoheheʻe arc a maʻalahi i ka lawelawe ʻana, hiki ke hana ʻia nā hana welding ma nā wahi āpau me ka lako mana. He kūpono no ka wiliwili ʻana i nā mea metala like ʻole, nā mānoanoa like ʻole a me nā ʻano hana like ʻole;
(2) He kūpono wale nō ka hoʻoheheʻe ʻia ʻana o ke arc submerged no nā kūlana kuʻihao palahalaha, a ʻaʻole kūpono no ka wiliwili ʻana i nā papa lahilahi me ka mānoanoa ma lalo o 1mm. Ma muli o ke komo hohonu ʻana o ka welding arc submerged, ka huahana kiʻekiʻe a me ke kiʻekiʻe o ka hana mechanized, kūpono ia no ka wiliwili lōʻihi o nā ʻano papa waena a me ka mānoanoa. ʻO nā mea i hiki ke welded e ka submerged arc welding ua hoʻomohala ʻia mai ke kila structural carbon a hiki i ke kila kila haʻahaʻa, ke kila kila, ke kila wela, a me nā mea ʻē aʻe, a me kekahi mau metala non-ferrous, e like me nā nickel-based alloys, titanium. nā huila, a me nā mea hao keleawe.
4. Kuʻi kinoea
ʻO ka hoʻoheheʻe ʻana i ke kinoea e hoʻohana ana i ke kinoea kūwaho ma ke ʻano he arc a pale i ke arc a me ka wahi wili i kapa ʻia ʻo gas shielded arc welding, a i ʻole wili kinoea no ka pōkole. Hoʻokaʻawale pinepine ʻia ka hoʻoheheʻe uila i loko o ka electrode non-melting electrode (tungsten electrode) inert gas shielded welding a me ka hoʻoheheʻe electrode kinoea hoʻoheheʻe ʻia, oxidizing mixed kinoea pale kuʻi, CO2 kinoea pale wili a me tubular uea kinoea hoʻoheheʻe ʻia e like me ka hoʻoheheʻe ʻia o ka electrode a i ʻole. ʻaʻole a ʻokoʻa ke kinoea pale.
I waena o lākou, hiki ke hoʻohana ʻia ka hoʻoheheʻe ʻana i ke kinoea hoʻoheheʻe inert loa no ka welding kokoke i nā metala a me nā alloys, akā ma muli o kona kumukūʻai kiʻekiʻe, hoʻohana pinepine ʻia no ka wiliwili ʻana i nā metala non-ferrous e like me ke aluminika, magnesium, titanium a me ke keleawe. e like me ke kila kila a me ke kila wela. Ma waho aʻe o nā pōmaikaʻi nui o ka hoʻoheheʻe ʻana i ke kinoea electrode hoʻoheheʻe ʻole ʻia (hiki ke welded i nā kūlana like ʻole; kūpono no ka wili ʻana o ka hapa nui o nā metala e like me nā metala non-ferrous, stainless steel, heat-resistant steel, carbon steel, and alloy steel) , ia no hoi ia i na pono o ka wikiwiki kuʻihao a me ka oi aku deposition pono.
5. ʻO ke kuʻi ʻana o Plasma arc
Hoʻohana nui ʻia nā arcs Plasma i ka wiliwili, pena a me ka uhi ʻana. Hiki iā ia ke wiliwili i nā mea hana ʻoi aku ka lahilahi a me ka lahilahi (e like me ke kuʻi ʻana o nā metala lahilahi ma lalo o 1mm).
6. Electroslag welding
Hiki i ka Electroslag welding ke weld i nā ʻano kila carbon structural steels, low-alloy high-streng steels, heat-resistant steels and medium-alloy steels, a ua hoʻohana nui ʻia i ka hana ʻana i nā paila, nā moku kaomi, nā mīkini kaumaha, nā mea hao a me nā moku. Eia kekahi, hiki ke hoʻohana ʻia ka welding electroslag no ka hoʻoulu ʻana i ka ʻāina nui a me ka hoʻoponopono hou ʻana.
7. Kuʻi uila uila
He mea paʻakikī, pipiʻi, a koi i ka mālama kiʻekiʻe; kiʻekiʻe nā koi o ka hui ʻana o nā weldments, a ua kaupalena ʻia ka nui e ka nui o ke keʻena vacuum; Pono ka pale X-ray. Hiki ke hoʻohana ʻia ka hoʻoheheʻe ʻana i ke kukui uila e wili i ka hapa nui o nā metala a me nā mea hana e koi ana i ka liʻiliʻi deformation a me ke ʻano kiʻekiʻe. I kēia manawa, ua hoʻohana nui ʻia ka welding electron beam i nā mea kani pololei, nā mika a me nā ʻoihana uila.
ʻO Brazing—E hoʻohana ana i kahi mea metala me kahi mea hoʻoheheʻe haʻahaʻa ma mua o ka metala kumu e like me ka solder, me ka hoʻohana ʻana i ka solder wai e hoʻomaʻemaʻe i ka metala kumu, e hoʻopiha i ke āpau, a me ka interdiffusion me ka metala kumu e ʻike ai i ka pilina o ka weldment.
1. ʻO ka lapalapa ahi:
He kūpono ka lapalapa ahi no ka hoʻopaʻa ʻana i nā mea e like me ke kila kalapona, ka hao hao, ke keleawe a me kāna mau ala. ʻO ka lapalapa oxyacetylene kahi lapalapa maʻamau.
2. Kūʻē brazing
Hoʻokaʻawale ʻia ʻo Resistance brazing i ka hoʻomehana pololei a me ka hoʻomehana ʻole. He kūpono ka brazing hoʻoheheʻe ʻana no ka brazing o nā weldments me nā ʻokoʻa nui i nā waiwai thermophysical a me nā ʻokoʻa nui o ka mānoanoa. 3. ʻO ka hoʻouluʻana i ka hoʻouluʻana: Hōʻikeʻia ka hoʻouluʻana i ka hoʻouluʻana i ka hoʻomehana wikiwiki, ka hana kiʻekiʻe, ka hoʻomehana kūloko, a me ka automation maʻalahi. E like me ke ʻano o ka pale ʻana, hiki ke hoʻokaʻawale ʻia i ka induction brazing i ka ea, induction brazing i ka pale kinoea a me ka induction brazing i ka vacuum.
ʻO ke kuʻi paʻi - pono e hoʻoikaika i ke kaʻina hana kuʻi ma luna o ka weldment, i hoʻokaʻawale ʻia i ke kuʻi kūʻē a me ka welding ultrasonic.
1. Kūʻē kūʻē
ʻEhā mau ʻano hana kuʻi kūʻē nui, ʻo ia hoʻi ka wiliwili wahi, ka wili wili, ka wili projection a me ka wili kī. He kūpono ke kuʻi ʻana no nā lālā pā lahilahi i hoʻopaʻa ʻia a ʻōwili ʻia i hiki ke uhi ʻia, ʻaʻole pono nā hui i ka airtightness, a ʻoi aku ka mānoanoa ma mua o 3mm. Hoʻohana nui ʻia ʻo Seam welding i ka welding sheet o nā pahu aila, nā kini, nā radiators, nā mokulele a me nā pahu wahie kaʻa. Hoʻohana nui ʻia ka wili projection no ka hoʻopaʻa ʻana i nā ʻāpana o ke kila kalapona haʻahaʻa a me ke kila kila haʻahaʻa. ʻO ka mānoanoa kūpono loa no ka hoʻoheheʻe ʻana i ka pā projection he 0.5-4mm.
2. Ultrasonic welding
ʻO ka hoʻoheheʻe kani kani i ke kumu kūpono no ka wiliwili ʻana i ka hapa nui o nā thermoplastics.
