He haʻahaʻa haʻahaʻa haʻahaʻa nā alloys Titanium, ikaika kikoʻī kiʻekiʻe, kūpaʻa maikaʻi i ka corrosion, haʻahaʻa haʻahaʻa thermal conductivity, non-toxic a non-magnetic, a hiki ke welded; hoʻohana nui ʻia lākou i ka mokulele, aerospace, chemical, petroleum, uila, lāʻau lapaʻau, kūkulu hale, nā mea haʻuki a me nā ʻano ʻē aʻe.
ʻO nā ʻano hoʻoheheʻe maʻamau no ka titanium a me ka titanium alloys e like me: argon arc welding, submerged arc welding, vacuum electron beam welding, etc.
Hoʻomākaukau ma mua o ka wili
ʻO ka maikaʻi o ka ili o ka weldment a me ka titanium welding wire he mana nui i nā ʻano mechanical o ka hui welded, no laila pono e hoʻomaʻemaʻe pono ʻia.
1) Hoʻomaʻemaʻe mīkini: No nā welds ʻaʻole makemake i ka maikaʻi kuʻihao kiʻekiʻe a paʻakikī paha i ka pickle, hiki ke hoʻohana ʻia ke one maikaʻi a i ʻole ke kila kila kila e holoi ai iā lākou, akā ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka carbide melemele e ʻoki i ka pā titanium e wehe i ka kiʻiʻoniʻoni oxide.
2) Ke hoʻomaʻemaʻe kemika: Ma mua o ke kuʻi ʻana, hiki ke kiʻi ʻia ka ʻāpana hoʻāʻo a me ka uea kuʻi. Hiki i ka hopena pickling ke HF (5%) + HNO3 (35%) wai. Holoi me ka wai maʻemaʻe ma hope o ka pickling, a weld koke ma hope o ka maloʻo ʻana. A i ʻole e hoʻohana i ka acetone, ethanol, carbon tetrachloride, methanol, a me nā mea ʻē aʻe no ka holoi ʻana i ka ʻūhā pā titanium a me nā ʻaoʻao ʻelua (ma loko o 50mm kēlā me kēia), ka ʻili o ka uwea kuʻi, a me ka ʻāpana kahi e hoʻopili ai ka mea paʻa i ka pā titanium.
3) Ke koho ʻana i nā mea hana kuʻi: No ka wili argon arc o ka titanium a me ka titanium alloy tungsten plates, kahi DC argon arc welding power source me nā hiʻohiʻona o waho a me ka hoʻomaka ʻana o ka arc kiʻekiʻe e koho ʻia, a ʻo ka manawa hāʻawi kinoea i hoʻopaneʻe ʻia ʻaʻole i emi iho. 15 kekona e pale aku i ka oxidation a me ka contamination o ka weldment.
4) Ke koho ʻana i nā mea hoʻoheheʻe: ʻAʻole i emi ka maʻemaʻe o ke kinoea argon ma mua o 99.99%, ʻo ka hau ma lalo o -40 ℃, a ʻo ka hapa nui o nā haumia he 0.001%. Ke hāʻule ke kaomi i ka cylinder argon i 0.981MPa, pono e hoʻōki i ka pale ʻana i ka maikaʻi o ka hui welded.
Loaʻa i nā lako wili Xinfa nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ke kumu kūʻai haʻahaʻa. No nā kikoʻī, e kipa:Welding & Oki Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
5) Ka pale kinoea a me ka wela welding: He haʻahaʻa ka hui paipu titanium i ka wā wili. I mea e pale aku ai i ka hui welded mai ka haumia ʻana e nā kinoea ʻino a me nā mea i nā wela kiʻekiʻe, pono e hoʻopili ʻia ka wahi weld a me ka weld i ka pale welding pono a me ka mālama ʻana i ka mahana, a ʻo ka mahana ma lalo o 250 ℃.
Nā kuhikuhi hana
1. I ka hana ana i ka manual argon arc welding, ka palena iki (10 ~ 15 °) pono e malamaia ma waena o ka welding wire a me ka weldment. Pono e hānai ʻia ka uea hoʻoheheʻe ʻia i loko o ka loko i hoʻoheheʻe ʻia me ka holo ʻana ma ka ʻaoʻao mua o ka wai i hoʻoheheʻe ʻia, a ʻaʻole pono e hoʻoneʻe ʻia ka hopena o ka uea hoʻoheheʻe ʻia mai ke kahua pale argon.
2. I ka wā e wiliwili ai, ʻaʻole e koli ma ka ʻaoʻao. I ka wā e pono ai ke kowali, pono e haʻahaʻa ke alapine a ʻaʻole nui ka nui o ka kowali i mea e pale ai i ka pale ʻana i ke kinoea argon.
3. I ka wā e wāwahi ai i ke arc a hoʻopau i ka weld, e hoʻomau i ka hele ʻana i ka pale argon a hiki i ka hoʻomaloʻo ʻana o ka weld a me ka metala ma ka wahi wela i lalo o 350 ℃ ma mua o ka wehe ʻana i ka pū wili.
Ka waihoʻoluʻu o ka weld a me ka ʻāpana wela
1. Wahi Weld
Keʻokeʻo kala, melemele māmā (ʻae ʻia no nā welds pae mua, ʻelua a me ke kolu); ʻeleʻele melemele (ʻae ʻia no nā welds pae lua a me ke kolu); poni gula (ʻae ʻia no nā welds pae ʻekolu); ʻeleʻele uliuli (ʻaʻole ʻae ʻia no nā welds pae mua, ʻelua a me ke kolu).
2. Wahi i pili i ka wela
Keʻokeʻo kala, melemele māmā (ʻae ʻia no nā welds pae mua, ʻelua a me ke kolu); melemele ʻeleʻele, poni gula (ʻae ʻia no nā welds pae lua a me ke kolu); ʻeleʻele uliuli (ʻae ʻia no nā welds pae ʻekolu).
