He aha ke komo ʻana o ka welding?E pili ana ia i ka hohonu hehee o ka metala kumu a i ʻole ka pahu weld mua ma ka ʻāpana keʻa o ka hui welded.
ʻO nā hui hui pū kekahi: weld seam (0A), fusion zone (AB) a me ka wela wela (BC).
KaʻAnuʻu 1: Sampling
(1) Oki kūlana o kuʻihao komo hāpana: a.Hōʻalo i nā kūlana hoʻomaka a hoʻomaha
b.E ʻoki i ka 1/3 o ka weld scar
c.Ke emi ka lōʻihi o ka weld ma lalo o 20mm, e ʻoki i ka waena o ka weld scar.
(2) Oki
A. E hoʻohui i ka lako mana a nānā inā hoʻokō nā mea ana i nā koi hoʻāʻo;E like me ka mea i hōʻike ʻia ma ke Kiʻi 1, wehe i ka hale pale o ka mīkini ʻoki metallographic a hoʻokomo i ka pahu hoʻohālike metala e hoʻāʻo ʻia.
(E hoʻomaopopo: E hoʻopaʻa pono i ka poloka metala!)
b.E like me ka mea i hōʻike ʻia ma ke Kiʻi 2, e pani i ka pūpū pale o ka mīkini ʻoki metallographic, e wehe i ka pahu wai, a e hoʻohuli i ka hoʻololi mana;E paʻa i ka lima o ka mīkini ʻoki metala a kaomi mālie i lalo e ʻoki i ka laʻana metala.Ma hope o ka ʻoki ʻana, ʻo ka lōʻihi, ka laulā a me ke kiʻekiʻe o ka hāpana metala e emi iho ma mua o 4mm;E pani i ka pahu wai, e hoopau i ka mana, a e lawe i waho i ka mea metala.
b.E like me ka mea i hōʻike ʻia ma ke Kiʻi 2, e pani i ka pūpū pale o ka mīkini ʻoki metallographic, e wehe i ka pahu wai, a e hoʻohuli i ka hoʻololi mana;E paʻa i ka lima o ka mīkini ʻoki metala a kaomi mālie i lalo e ʻoki i ka laʻana metala.Ma hope o ka ʻoki ʻana, ʻo ka lōʻihi, ka laulā a me ke kiʻekiʻe o ka hāpana metala e emi iho ma mua o 4mm;E pani i ka pahu wai, e hoopau i ka mana, a e lawe i waho i ka mea metala.
KaʻAnuʻu 3: Corrosion
(1) E like me ka mea i hōʻike ʻia ma ka Fig. 5, e hoʻohana i ka waiʻona piha a me ka waikawa nitric e hoʻomākaukau ai i ka hopena corrosion (3-5% nitric acid a me ka waiʻona) i loko o ke kīʻaha ana, e hoʻokomo i ka hāpana metala i loko o ka hopena corrosion a i ʻole e hoʻohana i kahi pulu liʻiliʻi e holoi. ka ʻili i ʻoki ʻia no ka ʻino.ʻO ka manawa corrosion ma kahi o 10-15 kekona, a pono e nānā ʻia ka hopena corrosion kikoʻī.
(2) E like me ka hōʻike ʻana ma ka Fig. 6, ma hope o ka ʻino ʻana, e lawe i waho i ka pahu hōʻailona metala me nā tweezers (e hoʻomaopopo: mai hoʻopā i ka wai ʻino me nā lima), a hoʻomaʻemaʻe i ka hopena ʻino ma luna o ka ʻili o ka pahu hāpana metala me ka maʻemaʻe. wai.

KaʻAnuʻu Hana 5: Hōʻike hōʻike no ke komo ʻana a me ka mālama ʻana i nā laʻana
(1) Hōʻike hōʻike hōʻike hoʻopaʻa ʻana i ke komo ʻana:
a.Hoʻohui ʻia i ke kiʻi ʻāpana keʻa o ka ʻāpana i nānā ʻia
b.E kaha i ke ana ana o ke komo ana o ka welding ma ke kii
c.Hoʻohui ʻikepili
