Weld mā: Mea Maluna a me Cuticura

Kuʻihao - kekahi o ka mea nui wale? Iecaianoaaiiuo keʻano o ka hanaʻana. Me ia, i ka pilina ua i ke kila na apana i loko o ka loa e lauwili manao. Like i loko o ka hihia o nā hanalima keʻano o ka hanaʻana, i kekahi manawa, aia no he mare. pili weld mā ma lalo o ka mea, a hiki loa i ka emi ka pono o ka hoʻopau 'ana i huina hoonui, ināʻaʻole e ia make hana.

Mea Maluna

Ma ke alanui, pehea la e hiki ai ia lakou e maheleia? All weld mā e māheleʻia i loko o ekolu nui pūʻulu.

• I waho.
• Kūloko.
• Looping.

Mawaho mā weld mea pinepine o ka waeʻano oi aku ka nui. Ua nā: loa ka nui, e like me ka pohupani hale o ka hui laina, okoa nodules, "ʻoki", ka iwi shrinkage, aʻaʻole i loko iho i loko o ke kaʻina hana o ka kuʻihao craters, na mawae a me porosity. Nonuniform weld laula i pili i keia? Ueo. Ua Ua manaoio aku i ka mea mawaho mā o welded ami i ka mea uuku pilikia loa mahele.

Alaila, ka mea maloko nā ili, ka mea, aole i hiki maopopo moa inclusions lehulehu o slag wahi, a he mau māwae, i loko o ka mānoanoa o ka weld metala. Me ka pili ana i ka ma mā, ka mea fistulas, e holo ana ma ka holoʻokoʻa mānoanoa o ka hapa mawae, a me ka burnout.

I ka papa kuhikuhiE kumu o kuʻihao mā

• ka wā ho'āʻo nei e hoʻohana loa nike a me ka haʻahaʻa-papa lako kokoke mau ka mea, hōʻike.
• ʻO ia ke ke mai la oia no ka poe ilihune ma Hawaiʻi o ke kuʻihao lako a pan. Eia kekahi, i ke alapine (frequency) o ka hanana o mā pinepine maoli he hope ilihune? Aiiio mea i hoʻohanaʻia e hoʻomalu.
• O ka ihu, i kēia hana he nui ma ka 'aʻe ana i ka' enehana.
• Nui mā ma ka weld ulana i ole uncommon no inexperienced 'Oihana me ka haahaa makahiki paha.

He oluolu ke ike i ka mea, ua loaa i ka loa kiʻekiʻe-kona mea e like me nā huahana ma ka hihia o ka pono o ka maopopo hana nona iho lako a pan. Mai poina e pili ana i ka pono o ka workspace. Penei, he nui scaly ulana a me ka 'aʻe' ana o kona laula ua nui pinepine i loaʻa i loko o hihia ma ka welder (a hiki i ka hoao ana) hana i loko o ka ke koikoi kūlana.

I ka mea,ʻaʻole accidental i loko o nā koi no ka manaʻo o ke kuʻihao loaʻa nā 'ikamu i i pololei ai stipulate i piha nā haumāna i ka wahiʻoihana, ina kona mea e like ai ergonomics.

nui 'ana i kumumanaʻo

ʻO ka novice welders maopopo loa ia e hoʻonui loa ulana ikaika pono i ka loaa ana o ka mea o 1-2 mm o. I ka Ia manawa ka ia welders pinepine ae aku i ka ahailono ka wā e waiwai o ka 3-4 mm o. Holo nōhie, ma na mea hoopii, aohe hewa me ia, akā, i ka wā e hele mai ai i huahana, i mau i loko o ka hōʻeuʻeu noho ana o ka haawe. A pau i kēia hiki aku ai i stress lehulehu, a me kaʻoi ulu i loko o ka likelihood o ka haki.

undercut

E like me mākou i mai la ia, mā ma welds a me ka pili 'o Randy i'āina pilikia loa. Ia mea,ʻaʻole paʻakikī e noonoo ai i na mea e hiki mai ana ina mea e ia i loko o nā lāliʻi, manao ia e lele aku, no ka mea hoike, ma ke kākoʻo 'ole o ke alahao alahaka. Ka mea, ua oi loa pilikia i loko o ka hihia o kuʻihao māhele mai kuhiliʻole kila, e e hoʻohana ma lalo o na kumu o ka mau ana wela hou.

Ka noho pilikia loa i undercut, e like me ka mea mau i ke kino "o na pu ki" anakahi uila, a e ke kiaʻana i kāna i loko o ka mea palupalu loa ke kina ole weld. Eia hou, ka mea, me ka nui loa ho'ēmi i kona hana pauku e like me he loa hopena maikaʻi 'ole ma o ka ikaika o ka pilina.

Nō kāu, i kēia mau mawaho mā ma welds i loko o ka hapanui o na hihia i ole ee a. O ke kumu ho i ka mea i ka mea hiki ke hooheheeia (IeAUPIIe, IAa IO) e no i ka haʻahaʻa-Profile mare ana, a hiki alakai i ka loa nui hopena.

E like me ka mea mau undercuts?

Ua ke kumu nui hoike he nui loaʻikena. Ma ka hui pu ana me ka lōʻihi piʻo, ua ololi hoʻolako aneane hoʻokahi haneri pakeneka pahiki o ko lākou mau hanana. Eia kekahi, ma kekahi hihia, undercuts i hoʻomaka ai ka wā i lanakila kokololio pohupani hale paio hahana maoli nō kumu ma luna o ka mea hiki ke hooheheeia ili honua.

Inā ka manao nae he wahi nui, o ka mea liilii loa mā ma welds a me nā hui o kēia 'ano e loa unacceptable. Pololeiʻiʻo nō ia ia ka hoʻohana 'ana i ka lahilahi maemae kuʻihao ulana. Inā he mea ia manawa kūpono au mamuli ia mea maikaʻi, e loa e puku i (e hoailona oukou i ka pili hope i hoʻopuka ai i nā mea a pau mā).

Lots undercooked mea hiki ke hooheheeia

Inā ia i kekahi koa o Nyos i pono ma ka ulana mānoanoa, ia mea'āina pilikia loa. Mua, huli ia i ke kina hiki ke hoʻohana wale i ka flaw. Ka lua, ka mea, e hou loaa kekahi kumu aʻo nui i loko o ka mea hiki ke hooheheeia. Ma ka huipūʻana a me ka 'aʻe' ana o kekahi welded 'ole, i keia hiki aku ai i ka pilikia o ka premature ole lāliʻi. No pinepine ia na mā ma welds e ala aʻeʻoe i loko o ka hihia o ka hoʻohana oka a kila a me ka poe ilihune kuʻihao lako a pan.

Porosity (nānā 'ole o kona wahi) ikaika ho'ēmi i kā ikaika waiwai i unacceptable cia, hiki aku ai i "delamination" o ka mea hiki ke hooheheeia, a laila i ka poino o kona maoli' ole. Details a me ka haahaa porosity i kekahi mau manawa hou aku paha e uhai ma lalo o haawe ana a hiki i ka hoomaka ana o ka hana. Me ka ili o ka hewa kinoea i wale mai i manawa, e hookaawale ia lana mai o ka hooheheeia metala, ahu iho.

E like me nā mea a pau ano o ka weld mā, ka mea, i loa pinepine e ala aʻeʻoe i loko o ka hihia o ka haʻahaʻa a heʻiʻo maka nō nā uila aʻa lolo. Ua pinepine ka hana i ka porosity aicieeaao no o kekahi impurities i paleia lakou kinoea. Like i loko o ka mua hihia, i kēia 'ano o ke kina hiki no hoi i hoʻomaka ai ma excessively kiʻekiʻe kuʻihao holo ka wā corny hana kue i ka pono o ka aiiay kinoea "wai auau".

slag inclusions

Inclusions o slag nui luku aku i ka uniformity o ka metala 'ole. Ke Classic kumu o ka ho okumu - inadvertent koli iho la i olelo ili mai ka lepo a me ka unahiʻole, i residues. Ke pahiki o ko lākou mau hanana mālama i ka 'Aʻohe me ka proviso kuʻihao, ahu iho o aiiay kinoea. Pohihihi keia huli a puni shape hoʻaʻohe pilikia, huahana mai o ia e hele OTC.

E noke i ina ia ma ka kuʻihao ka tungsten'ūholo uila, i ke loaʻa nā lāliʻi i metala (particles). Lākou degere o ka pilikia - like i loko o ka mua hihia ( 'o ia hoʻi, ka mea i ana mā ma welds ..).

mawae

Aia mau transverse a lonikū hiki nā i ka ulana a me ka mea hiki ke hooheheeia ma a kokoke ia. Ka mea, ua mākaukau ka mea no ka mea, i loko o kekahi mau hihia, emi ka ikaika me mechanical o ka huina hoonui a me ka kuekueni iʻaneʻane Aʻohe. Ke kaumaha ma muli o ka waiwai o ka mea e e welded, ke mau māwae, hiki nā noho ma kona palapala wahi, a hohola iho la i ka holoʻokoʻa loa o ka workpiece i loko o ka manawa pōkole wale nō.

'Aʻole surprisingly, keia mea o ka noho pilikia loa mā ma welds. Hae ma ka hapanui o na hihia i kauoha koke rejection o ia eiiiiiaiou, nānā 'ole o kona manao i (me ke koe o ka loa kumuʻanoʻole maoli' ikamu).

Ole-uniformity o na nakaka

No laila, ka mea i kapaia o discrepancy nui o geometrical kiko'î o ka pili 'o Randy koi' ia i loko o ka rula ano. Aloha kau, ina kuʻihao mea he "nahesa", obliquely, a no laila, ma luna o. N., Ua pono ke hele mai i ka likeʻano o ke kina.

Loa pinepine ka mea, eʻikeʻia i loko o ka hana o inexperienced welders, e like me nui kēia, hemahema lako a pan a me ka banal wikiwiki. Mea weliweli a keia kina i ua pinepine hui me undercooked, i mea mua loa aku pilikia loa. Inā ka haiahū kūmau, mai ka laina iho o ka hui i mailuilu haalele, a aole i i ka ho'ēmiʻana i loko o ka ikaika o ka huina hoonui, o ka ke keʻena hiki ke ae i ka hana.

Ma keia hihia, hoomanao mau i kekahi ano mea: no ka uuku o ka huina o ka hoʻololi mai o ka waihona ipu keleawe'ōlinolino, ahu iho i fusing, na ka ikaika me mechanical hewa o ka welded huahana. O ka papa, ma o ka hana ana o kekahi hale? Ieoaeunoaa iauaeoia (hoʻomehana honua wahi ponoi, no ka laʻana) i loko o undervoltage kumu, e hana me ka haoʻa i na nakaka wale unrealistic. Naʻe, i loko o keia hihia, ka mea e ole ho i kekahi kamepiula.

XIX. Pāʻoihana, pilikia fixes

Iki aku nei au i ke kēia: i loko o ka hapanui hihia a pau, i ke kaʻina hana o ka hoʻopau o ka mā o welds kūkākūkā, aole ia i hana i ke aloha, e like me ia ma ka oi a emi kānana OTC a pau me nā huahana me kekahi flaws wale mare. Akā, i kekahi manawa ka mea maoli i ka hihia i ka kina mea,ʻaʻole he nui, akā, no ka mea, hiki ke eliminated. Pehea e hana ia?

Ma ka hihia o ke oki ili hao me ka kila 'ole (wai koko-piʻo kuʻihao), malama ua holoiʻia i ka wahi o ka pilikia ka pilina, a laila retry. Inā loaʻa nā nīnūnē mawaho mā ma welds (haoʻa hui pāpaʻu lua), ka mea hiki wale ke one. O ka holo ana, ia aʻole e hoʻomau ana, a lawe he nui loa metala, ahu iho.

nui Hou

I ka wa e hele mai ai i huahana o kuhiliʻole kila, a mea paha i obligatory wela lapaʻau, pono e hana i ka? Iaea o mā ma ka welds wale (!) Ma hope o ka Holiday i loko o ke ana wela huahelu mai ka 450 a hiki i 650 ° C.

? Iaea o nāʻano likeʻole

Ke easiest ala e paʻipaʻi sagging a me ka haoʻa me mechanical ami. Ma keia hihia, i ka huina e like ua holoiʻia (me mākou i'ōleloʻia nei). mākou i olelo mai ma luna e pili ana i na fixes undercuts, akā, hookahi hou mākou e hoailona oukou - me ka mā au mamuli oi kūpono e koke culled, no kona hoʻohana hiki e weliweli!

Inā 'oe i ke kuni i ka mea-ma (i mea ole i pono ole), i ka hoʻopau o ka weld mā lilo loa na mea: mua, e like me ka ili no e hoomaikai i, a laila hoʻolapalapa mea hou. Ka hola no laila, hana me craters.

XIX. Olelo "mea hoʻonani"

I hoʻopau o ka mā i, e hooko me kekahi mauʻanoʻenehana ana. Mua, e pono e hahai i ka mea rula: ka hemahema hapa lōʻihi pono like me kona laula hua hoʻohui 10-20 mm o E e waiho "pono ma ka hihia".

Nui! Ka laula o ke kuʻihao ulana ma hope hou provarkoy e ole oi palua kona nui ma mua e hoomaka ana i ka hana. Mai e palaualelo e koho flaws alakaʻi mākaukau, ili. Mua, ka mea, ua ālai 'slag, mai ke komoʻana i ka mea hiki ke hooheheeia apana. Eia hou, keia guileless ana, e kōkua oia i ka hana a me ka hoomahuahua i ka pono o kona hopena.

He mea nui e hoomakaukau i ka hāpana no hou-embeds i ka'āina. Inā 'oe e hoʻohana LBM ( "Bulgarian"), ia mea maikaʻi, e lawe i ka holo ana o ka mea uuku anawaena. I kaʻaoʻao maka o ka hāpana pono e hana i mea like hiki i laumania, free o burrs 'ole' ē aʻe nei iluna o māhele i ka kuʻihao kaʻina hana ke huli i nā mea a pau o ka hookahi slag.

I ka wa e hele mai i ka Aluminum i huiʻia, titanium, a me ka oka a pau o kēia mau mea hiki ke hooheheeia, no ka mea mea e hoʻokokoke aku responsibly. Mua, i pili i ka mā ma keia hihia e e hoʻohana wale (!) Mechanical ki ina hana like, ka hoʻohana 'ana i ka piʻo kuʻihao ua ole ae. Ka hapanui o kaʻoi loa, e kua i lalo i ka poino pauku, ua holoiʻia a me ka hou-brew ulana.

A memo ma ka pilikia fixes

Wahi? Ee - hou-brewed i huiʻia pono hou undergo i ke kaʻina hana OTC. Inā he kina i loko o kekahi a me kekahiʻano o ka palekana, he mea hiki, e ho'āʻo i ka hooponopono hou. Nui! I ka nui o ka hooponopono hou hilinaʻi nui ma luna o ke kila papa a me nā 'ano o ka huina hoonui, akā, ma lalo o maʻamau rula hiki ole oe' oiaʻiʻo ma loko i ka hana no elua oi aku paha, ekolu manawa, like ole ia he mea he hoopaapaa emi i ka ikaika waiwai lāliʻi.

No laila mākou i ana no ka walaʻauʻanaʻano o weld mā.
