Hoʻoponopono pololei ka maikaʻi o ka welding i ka ikaika hui, palekana a me ke ola lawelawe. Hiki i nā welds hemahema ke hana i ka haki, leakage, ʻōpala a i ʻole nā ulia ʻoihana. Nui nā ʻoihana e hoʻouna i nā ʻāpana hewa no ka mea ʻaʻole lākou i hana maʻamau i ka nānā ʻana, e hoʻonui ana i nā kumukūʻai hana hou a hōʻino i ka inoa inoa. ʻO ka ʻoiaʻiʻo, ʻaʻole pono ʻoe i nā mea hana paʻakikī e kāohi i ka maikaʻi o ka weld—master ʻehā mau hoʻāʻo maʻamau (visual, penetrant, ultrasonic, destructive) a uhi ʻoe i ka spectrum holoʻokoʻa mai ka nānā wikiwiki ʻana i ka hōʻoia pololei. Hōʻike kēia ʻatikala i nā kī nui a me ka laulā noi o kēlā me kēia ʻano; Hiki i nā mea nānā manawa mua a me nā keʻena QA akamai ke kope koke i ke kahe hana.
Kumu kumu: e hahai i ka loina 'papau-i-hohonu, surface-to-core'—e imi mua i na hemahema o ka ili me na mea maalahi, alaila imi i na hemahema o loko huna me na hana oihana, a hope loa e hana i na ho'āʻo luku wahi e hōʻoiaʻiʻo ai i ka kūlike holoʻokoʻa. Mālama kēia i ke kumukūʻai nānā a hoʻonui i ka pono.
I. Nānā ʻike - ʻoi aku ka wikiwiki, ʻoi aku ka liʻiliʻi, hiki i nā mea a pau ke hana
ʻO ka nānā ʻike maka ka laina mua o ka pale; ʻaʻole koi ʻia nā mea hana kūikawā. I ka hana nui, hopu ia ≥80 % o na hemahema o ka ili i kekona.
1. He aha ka mea e nānā ai
Nui Weld: laula, kiʻekiʻe, lōʻihi i loko o ke kaha kiʻi ʻana (± 1 mm ka mea maʻamau).
Nā hemahema o ka ʻili: nā māwae (ʻoi aku ka weliweli), porosity, under-cut, incomplete penetration, overlap, slag inclusions.
ʻO ke kūlana ʻāpana: distortion, warpage, mis-alignment e hiki ke hoʻopilikia i ka hui o lalo.
2. Nā mea hana a me nā ʻanuʻu Mea hana: ruler kila, weld gauge (koho), kukui uila.
Nā ʻanuʻu: (i) Maʻemaʻe ʻōpala, ʻōpala, ʻaila; (ii) E nānā i ka hui holoʻokoʻa ma lalo o ke kukui ikaika, ʻoi aku ka nui o nā wahi hoʻomaka/kū a me nā manamana wāwae; (iii) E ana i ka lōʻihi o ka wāwae, ka puʻu, ka lōʻihi holoʻokoʻa; (iv) Hōʻole a hōʻailona paha no ka hoʻoponopono ʻana inā ʻike ʻia nā māwae, nā pores nui a i ʻole ka liʻiliʻi.
3. Ka lua
Huna ke kukui maikaʻi ʻole i nā māwae lauoho—e hoʻohana mau i ke kukui uila.
Wehe mālie i ka slag; mai ʻoki i ka ʻili a hana i nā hemahema 'false'.
Mai haʻalele i kahi māwae lauoho—e laha paha ma ka paia.
II. ʻO ka hoʻāʻo Penetrant (PT) - loaʻa nā puka liʻiliʻi liʻiliʻi / kokoke i ka ʻili
ʻO ka PT he kumu kūʻai haʻahaʻa, ʻaʻole luku ʻia no ka ʻike ʻana i nā micro-cracks a i ʻole pores ≤2 mm hohonu ʻaʻole hiki i ka maka ke ʻike. Ua kūpono i nā metala a me nā ʻano paʻakikī.
ʻO ka Principle Capillary hana ka huki ʻana i ka wai kala i loko o nā puka ʻili; holoi ʻia ka wai kala nui; ʻO ka mea hoʻomohala keʻokeʻo e huki i ke kala i waho, e hōʻike ana i ka hemahema.
Nā mea hana a me ke kaʻina hana Aerosol cans: cleaner, penetrant, developer; lole ʻaʻahu ʻole; mea holoi lauoho koho.
Nā ʻanuʻu: (i) E wili a hoʻohaʻahaʻa i kahi kaula 20 mm ma ka weld; (ii) E kāpīpī i ka mea kanu, mālama i ka pulu 10-20 min; (iii) Holoi i ka nui, hoʻomaʻemaʻe pololei i ka hui; (iv) E kāpī i kahi papa hoʻomohala lahilahi; (v) Ma hope o 5-10 min e nānā ma lalo o ke ao—nā laina kala = māwae, kiko = porosity.
Ka laulā a me nā palena Maikaʻi no: nā pōʻino i haki ʻia i ka ʻili ma nā ʻano ʻala a paʻakikī paha (nā paipu paipu, nā hale hoʻolei).
Nā palena: ʻaʻole hiki ke ʻike i nā hemahema o loko; hiki i ka ʻinoʻino ke hāʻawi i nā kelepona hoʻopunipuni; kūpono ʻole no nā mea porous (ka hao hao).
III. Ka ho'āʻo kani ultrasonic (UT) - ka iwi kuamoʻo no nā hemahema o loko
ʻO UT ke ʻano hana ʻino ʻole no ka hoʻopau ʻana o loko i nā welds mānoanoa (≥8 mm): nele i ka hui ʻana, kanu ʻia nā māwae, slag, porosity. He mea nui ia no nā hui hoʻopaʻa haʻahaʻa a koʻikoʻi paha.
Ku'ina Ho'ouna 'ia ke kani alapine piezo-electric i loko o ka weld. Hōʻike ʻia ka leo ma nā interface; ʻo ke kiʻekiʻe o ka lele ʻana a me ke kiʻekiʻe o ka leo e haʻi i ka mea hoʻohana i ka wahi a me ka nui o kahi mea hoʻohālike.
Nā lako a me nā kapuaʻi ʻike kīnā, māhoe kihi a pololei paha, hoʻopili ʻia (ʻaila a i ʻole glycerine), poloka calibration.
Nā ʻanuʻu: (i) E wili i ka pāpale wiliwili, wehe i ka ʻōpala/pena; (ii) Hoʻoponopono ma kahi poloka kuhikuhi; (iii) E hoʻopili i ka couplant, scan probe parallel a kū pololei i ke axis weld; (iv) E kaha i nā hōʻailona ma luna o ka pae loiloi; (v) Kūlana a me ka lōʻihi, hoʻokaʻawale i kēlā me kēia code (ISO 17640, AWS D1.1, GB/T 11345).
Nā pono
ʻAʻole luku loa; hiki ke ho'āʻo hou i ka hui like.
Ke komo hohonu (he mau mika ma nā forgings nui).
ʻO ka nānā ʻana wikiwiki—kūpono no ka nānā ʻana i ka leo kiʻekiʻe.
Hāʻawi i ka hohonu a me ka lōʻihi no ka hoʻolālā hoʻoponopono.
IV. Hoʻāʻo luku - hōʻoia o ka ikaika a me ka ductility
Wehe ʻia nā laʻana liʻiliʻi a wāwahi ʻia e hōʻoia i ka hāʻawi maoli ʻana o ka WPS i nā waiwai mechanical i makemake ʻia. ʻO ia wale nō ke ala e ʻike ai i ka 'ultimate reality'.
ʻO nā hoʻāʻo maʻamau
(a) Hoʻāʻo ʻo Tensile - e ana i ka ikaika tensile hope (UTS). ʻAe ʻia: weld UTS ≥90 % o ka base-metal UTS a me ka haʻihaʻi ma waho o ka weld a i ʻole e hoʻokō i ka waiwai code liʻiliʻi.
(b) ʻO ka piko ʻaoʻao a i ʻole ke aʻa-pilikia - hōʻoia i ka ductility a me ke kūʻokoʻa mai ka nele o ka hui. ʻAʻohe māwae hoʻokahi >3 mm ma ke alo hoʻopaʻapaʻa ma hope o 180° piʻo ma luna o kahi mandel Ø = 4 t.
Ka laʻana
maʻamau 3-5 mau ʻāpana i kēlā me kēia pūʻulu a i ʻole 50 m o ka weld. No nā papa hoʻāʻo hoʻonaʻauao WPS hou, ʻelua tensile a me ʻehā mau piko maʻamau.
Nā memo
Pono nā laʻana e hōʻike (mea like, mānoanoa, WPS).
Pono e calibrated nā mīkini; pono e hoʻoneʻe ʻia nā māwae o ka ʻoki ʻoki.
Hoʻohui me NDT: ʻike ʻo NDT i kahi, hōʻoia ʻo DT i nā waiwai.
V. Hale kūʻai-papahana hana (kope & paʻi)
ʻanuʻu 1 - 100 % ʻike e ka welder/operator; hoʻoponopono koke a ʻōpala paha.
KaʻAnuʻu Hana 2 – PT ma nā ʻāpana koʻikoʻi a i ʻole UT ma nā welds mānoanoa (spot-check a i ʻole 100% e like me ke koi ʻia e ke code).
KaʻAnuʻu Hana 3 - Hoʻopalapala hōʻino i kēlā me kēia ʻāpana; hoʻonui i ka laʻana inā hāʻule kekahi.
KaʻAnuʻu 4 - Hoʻokuʻu hope wale nō ma hope o ka hala ʻana o nā ʻanuʻu ʻekolu a me nā palapala.
E hoʻololi i ke alapine a me ke ʻano i kāu ʻoihana: pono paha nā mea lapaʻau a me nā ʻāpana kaʻa i 100% UT + mau mea luku; Hiki ke hilinaʻi ʻia nā lako hana maʻamau i ka PT/piʻo kiʻi kiʻi.
VI. Papa inoa o ka pitfall wikiwiki
Mai hoʻokuʻu i ka ʻike—ʻo nā māwae o ka ʻili ka 'aʻa' o nā hōʻole UT ma hope.
ʻAʻole hiki i ka PT ke haumia nā ʻāpana; ʻO ka hoʻomākaukau ʻana i ka ʻili he 80% o ka hopena.
Pono ʻo UT i ka calibration i kēlā me kēia lā a me kahi mea hana i aʻo ʻia; kihi ʻimi hewa = hala ʻole ka hui ʻana.
Pono e like me ka WPS like me nā laʻana luku; i ole ia he mea ole ka hoao ana.
E hoʻomaʻamaʻa i kēia mau ʻano hana ʻehā a e hopu koke ʻoe i nā hemahema, ʻoki i ke kumukūʻai hana hou a hōʻoiaʻiʻo ʻo kēlā me kēia huahana welded e haʻalele ana i kāu mea kanu he palekana a me ke code-compliant.
Inā loaʻa iā ʻoe nā koi mīkini wili, e ʻoluʻolu e kelepona iā Ms. Zhao
Hoʻokumu ʻia i ka makahiki 2006, ʻo PDKJ kahi mea hoʻolako ʻoihana o nā hoʻonā automation welding. Ua hala ka hui i ka ISO9001 international quality management system certification, ua ʻoi aku ma mua o 90 i ʻae ʻia a hoʻohana ʻia i nā patent aupuni, a he nui nā ʻenehana koʻikoʻi i ke kahua welding e hoʻopiha i ka ʻenehana loea ma ka home a ma waho. He ʻoihana ʻenehana kiʻekiʻe ʻāina.
