1.Pehea eweld kila māmā?
ʻO ke kila kalapona haʻahaʻa he haʻahaʻa kalapona a me ka plasticity maikaʻi, a hiki ke hoʻomākaukau ʻia i nā ʻano like ʻole o nā hono a me nā ʻāpana.I ke kaʻina hana welding, ʻaʻole maʻalahi ka hana ʻana i ka hale paʻakikī, a he liʻiliʻi hoʻi ka manaʻo e hana i nā māwae.I ka manawa like, ʻaʻole maʻalahi ka hana ʻana i nā pores.ʻO ia ka mea wiliwili maikaʻi loa.
ʻO ka wiliwili ʻana i ke kila kalapona haʻahaʻa ma o ka hoʻoheheʻe ʻia ʻana o ke kinoea, ka wiliwili arc manual, ka wiliwili ʻana i ke arc submerged, ka wiliwili pale kinoea a me nā ʻano hana ʻē aʻe e hiki ke loaʻa nā hui welded maikaʻi.Mai wela no ka manawa lōʻihi i ka hoʻohana ʻana i ka wili kinoea, i ʻole e maʻalahi ka nui o nā hua i loko o ka ʻāpana wela.Ke paʻa loa ka hui a haʻahaʻa ka mahana ambient, pono e hoʻomaʻamaʻa mua ʻia ka mea hana i 100 ~ 150 ° C e pale i nā māwae.
2.Pehea e wiliwili ai i ke kila kalapona waena?
Ma muli o ke kiʻekiʻe o ke kalapona kalapona kila, ʻo ka weld seam a me kona wahi i hoʻopili ʻia i ka wela e maʻalahi i nā hale paʻakikī a hana i nā māwae, no laila pono e hoʻomaʻamaʻa ʻia ma kahi o 300 ° C ma mua o ke kuʻi ʻana, a koi ʻia ka hoʻomaha mālie ma hope o ka wili.Hiki ke welded e ke kinoea kuʻihao, manual arc kuʻihao a me ka kinoea pale kuʻihao.Pono nā mea wiliwili e hoʻohana i ka AWS E7016, AWS E7015 a me nā mea uila ʻē aʻe me ke kūpaʻa ʻoi aku ka maikaʻi.
3.Pehea e wili ai i ka alumini a me ke alumini alumini?
ʻO nā alumini alumini a me nā alumini he mea maʻalahi e hana i nā kiʻiʻoniʻoni oxide me nā kikoʻī nui a me nā wahi hoʻoheheʻe kiʻekiʻe i ka wā wili.Hiki i kēia kiʻiʻoniʻoni oxide ke komo i ka nui o ka wai, no laila hiki ke hana ʻia nā hemahema e like me ka slag inclusions, fusion maikaʻi ʻole, a me nā pores i ka wā wili.Eia kekahi, nā alumini alumini Hiki nō hoʻi i nā māwae thermal.Hiki ke hana ʻia ka wiliwili alumini a me ka alumini ma o ka wili kinoea a i ʻole ka wiliwili arc manual.Eia naʻe, ʻaʻole i hoʻopaʻa ʻia ka wela o ka welding gas, a wikiwiki ka hoʻololi ʻana o ka wela o ka alumini, no laila ua haʻahaʻa ka hana hana, a nui ka deformation o ka mea hana, no laila ʻaʻole i hoʻohana ʻia koe wale nō nā papa lahilahi.I kēia manawa, hoʻohana ʻia kahi helu nui o ka AC argon arc welding method e weld i nā alumini a me nā alumini alumini, no ka mea, ua hoʻopaʻa ʻia ka wela, nā wili weld nani, liʻiliʻi deformation, pale argon, a hiki ke pale i ka slag inclusions a me nā pores.Inā hoʻohana ʻia ka welding arc manual e wili i ka alumini, kūpono ia no nā papa mānoanoa ma luna o 4mm.
ʻO nā māka o nā koʻokoʻo wiliwili i hoʻohana ʻia he aluminika 109, aluminika 209 a me aluminika 309. ʻO lākou a pau nā electrodes paʻakai me ka paʻa ʻole arc, e koi ana i ka mana hoʻohuli DC.
4.Pehea e wili ai i nā alloys titanium a me titanium?
ʻO Titanium kahi mea hana ikaika loa.I loko o ka wai a me ka paʻa paʻa ma luna o 600 ° C, he mea maʻalahi loa ia e hana me ka oxygen, nitrogen, hydrogen a me nā kinoea ʻē aʻe e hana i nā haumia ʻino a me ka embrittle titanium.No laila, ʻaʻole hiki ke hoʻohana ʻia ka wili kino oxygen-acetylene, manual arc welding a i ʻole ke kinoea pale ʻē aʻe no ka titanium a me ka titanium alloys, akā hiki ke hoʻohana ʻia wale nō ka welding argon arc, vacuum electron beam welding a me contact welding.
ʻO nā papa lahilahi ma lalo o 3mm i hoʻopaʻa ʻia e ka argon arc welding, pili pono ka mana me ka manawa pololei, ʻo ka maʻemaʻe o ke kinoea argon ʻaʻole i emi iho ma mua o 99.98%, pono ka nozzle e like me ka hiki i ka mea hana, pono ke ʻano o ka welding. liʻiliʻi, a ʻo ka wikiwiki o ka welding e wikiwiki.E hoʻomaikaʻi i ke ʻano kristal a hoʻopau i ke kaumaha welding.
5.Pehea eweld keleawea me na hui keleawe?
He nui nā pilikia o ka hoʻopili ʻana o ke keleawe a me ke keleawe, no ka mea, ʻoi aku ka maikaʻi o kā lākou conductivity thermal, no laila e maʻalahi ke hana i nā hemahema e like me ka impermeability a me ka fusion maikaʻi ʻole.Ma hope o ke kuʻi ʻana, e loaʻa ka deformation nui o ka mea hana, a ʻo ka weld a me ka fusion zone e pili pū ana i nā māwae a me ka nui o nā pores.ʻOi aku ka haʻahaʻa o nā waiwai mechanical o ka hui, ʻoi aku ka paʻakikī a me ka paʻakikī ma mua o ka metala kumu.Hiki ke hoʻohana ʻia ke kinoea welding e weld i ke keleawe ʻulaʻula, akā haʻahaʻa loa ka maikaʻi, nui ka deformation, a pono e hoʻomaʻamaʻa ʻia ma luna o 400 ° C, a ʻaʻole maikaʻi nā kūlana hana.Hiki ke ho'ohana 'ia ke keleawe 107 a i 'ole ke keleawe 227 electrodes, ua ho'ohuli 'ia ka mana me DC, mālama 'ia ke arc i ka ha'aha'a, a ua ho'ohana 'ia ke 'ano laina laina e ho'omaika'i ai i ke 'ano weld.Hammer ka weld ma hope o ka wili e hoʻomaikaʻi i ka maikaʻi o ka weld.Inā hoʻohana ʻia ka argon tungsten arc welding, hiki ke loaʻa nā hui welded kiʻekiʻe a hiki ke hōʻemi ʻia ka deformation o nā weldments.Hoʻohana ʻia ʻo Wire 201 no ka hoʻopaʻa ʻana i ka uea.Inā hoʻohana ʻia ka uea keleawe ʻulaʻula T2, pono e hoʻohana ʻia ka flux 301.Hoʻohana ka mana mana i ka pilina maikaʻi DC.Pono e hoʻomaʻemaʻe maikaʻi ʻia ka mea hana a me ka uea welding i ka wā e hoʻoemi ai i nā pores a me nā slag inclusions.Pono e hoʻohana ʻia ka manawa kiʻekiʻe a me ka wikiwiki kiʻekiʻe i ka wā e wili ai.
Hoʻohana pinepine ʻia ka hoʻoheheʻe kinoea no ka wili keleawe, a ʻo ka uea kuʻihao hiki ke uea 221, uea 222 a i ʻole uea 224, a me nā mea ʻē aʻe. ʻO kēia mau uea i loaʻa ke silika, tin, hao a me nā mea ʻē aʻe, hiki ke hoʻemi i ka pau ʻana o ka zinc i loko o ka wai hoʻoheheʻe. .Ma muli o ka haʻahaʻa haʻahaʻa hoʻoheheʻe kinoea, hiki ke hoʻemi ʻia ka pau ʻana o ka zinc ma ke keleawe;Hoʻohana ʻia kahi lapalapa o ka oxidation liʻiliʻi e uhi i ka ʻili o ka wai i hoʻoheheʻe ʻia me kahi papa o ka zinc oxide film, hiki ke hoʻemi i ka evaporation o ka zinc.Eia kekahi, hiki ke hoʻopaʻa ʻia ke keleawe e ka welding arc manual a me ka welding arc tungsten argon.
6.He aha nā hiʻohiʻona o ka wiliwili kila haʻahaʻa maʻamau?
ʻO ke kila haʻahaʻa haʻahaʻa maʻamau ka mea hoʻohana maʻamau no ka hana hou ʻana.ʻO ka hiʻohiʻona nui o kēia ʻano kuʻi kila, ʻo ia ka wahi i hoʻopili ʻia i ka wela o ka hui i ʻoi aku ka ikaika o ka paʻakikī, a ʻo ka maʻi hydrogen e hana i nā māwae anu i ka hui.Ke piʻi aʻe nei ke ʻano o ka paʻakikī a me ka pohā anu i ka piʻi ʻana o ka māka ikaika o ke kila hao haʻahaʻa maʻamau.
7.He aha ke ʻano hana kuʻihao o 16 manganese kila?
16 Pono e hoʻohana i ka hui 506 a i ʻole ka hui 507 a me nā electrodes kumu ʻē aʻe, DC hoʻohuli ʻia.Inā ʻaʻole nui ka manaʻo o ka māwae, hiki ke hoʻohana ʻia nā koʻokoʻo kuʻi waika e like me junction 502 a i ʻole junction 503, a ua like ke kaʻina hana kuʻi me ke kila kalapona haʻahaʻa;i ka wā e paʻa ai ka weldment a ʻoi aku ka haʻahaʻa o ka mahana ambient ma mua o -10 ° C, pono ka hoʻomehana ʻana ma mua o ka wili.Hiki ke loaʻa nā hopena ʻoluʻolu ma o ka hoʻoheheʻe ʻana i ka arc manual, ka hoʻoheheʻe arc submerged a i ʻole ka welding electroslag.
8.He aha ke ʻano hana kuʻi ʻana o No. 15 manganese vanadium a me No. 15 manganese titanium steel?
ʻO ka 15 manganese vanadium a me 15 manganese titanium no 40 kg maʻamau.Ma muli o ka hoʻohui ʻana o kekahi vanadium a i ʻole titanium, hoʻomaikaʻi ʻia ka pae ikaika o ke kila;akā ʻo kā lākou weldability, nā mea hoʻoheheʻe a me nā kaʻina hana e like me ka 16 manganese steel.Ua like ka hoohalike ana.Ke hoʻohana ʻia ka hoʻoheheʻe ʻana i ka arc submerged, hiki i ka uea kuʻihao ke 08 manganese kiʻekiʻe, 08 manganese 2 silicon, a me ka flux 431, flux 350 a i ʻole ka flux 250 hiki ke loaʻa nā hopena ʻoluʻolu.
9.He aha keʻano o ka hoʻopiliʻana o ka No. 18 manganese molybdenum niobium steel?
No. 18 manganese-molybdenum-niobium kila no ka 50 kg kiʻekiʻe-ikaika maʻamau haʻahaʻa-alloy kila, i hoʻohana pinepine 'ia i ka hanaʻana i nā mea koʻikoʻi wiliwili e like me kiʻekiʻe-press moku a me boiler pahu.Ma muli o kona ikaika kiʻekiʻe a me ka manaʻo paʻakikī nui, pono e lawe ʻia nā hana hoʻomehana kūloko i ka wā o ka wiliwili wahi.E makaʻala i ka hoʻomaloʻo ʻana i ka electrode a me ka hoʻomaʻemaʻe ʻana i ke awāwa e pale ai i nā māwae anu i hana ʻia e ka hydrogen.Hoʻohana ʻia ka wiliwili arc manual i ka hui 607 a me nā electrodes ʻē aʻe;Hoʻohana ʻia ka hoʻoheheʻe ʻana i ka wili wili me ka manganese kiʻekiʻe 08 a me ka molybdenum, a hiki ke wili ʻia me ka flux 250 a i ʻole flux 350.
