ʻO ke kila G115 kahi mea hou o ka mea kila wela me ka hana kiʻekiʻe kiʻekiʻe i hoʻomohala kūʻokoʻa i Kina, ka mea i hoʻohana nui ʻia i ka hana ʻana i nā paipu pā mānoanoa nui a me nā ʻāpana wela ʻē aʻe ma 630 ~ 650 °C. , a ʻo ia ke kumu nui e hoʻomaikaʻi ai i ka pae kūpono o nā ʻāpana mana wela.
Mai ka makahiki 2016, ke hoʻomau nei mākou i ka hoʻomohala ʻana a me ka hoʻonui ʻana i nā mea hoʻohana welding no ke kila G115, a ua hana pū mākou me nā ʻoihana noiʻi like ʻole a me nā mea hoʻohana i kēia kaʻina hana, a loaʻa nā hopena hua.I ʻAukake 2020, ua kōkua maikaʻi ʻo ia i ka mālama ʻana i ka "G115 Heat-resistant Steel Welding Process Technology Seminar" ma Kunshan, ma hope o ka hoʻokumu ʻia ʻana o nā minuke o ka hālāwai (e ʻike i ke kiʻi ma lalo), a me nā palapala alakaʻi koʻikoʻi e like me "G115 Steel Welding. Ua hoʻokumu ʻia nā hōʻailona hōʻailona hōʻikeʻike kaʻina hana "a me "G115 Steel Welding Process Alanui a me nā ʻāpana kī".
Ma hope o ka wehewehe ʻana i nā koi hana a me nā kikoʻī parameter ma ka hālāwai, ua hoʻomau mākou i ka hoʻopukapuka hou aku i ka hoʻomohala ʻana, a ua hoʻomohala i kahi piha o nā mea hoʻoheheʻe no G115 me ke kaʻina hana kuʻi maikaʻi (hiki i ka wili uila a me TIG ke hoʻokō i ke kūlana piha piha), kūpaʻa. hana, a hoʻokō i nā koi o nā hōʻailona hana like ʻole i hoʻonohonoho ʻia e ka hālāwai.Hōʻike ʻia nā hiʻohiʻona kikoʻī a me nā hiʻohiʻona ma ka Papa 1 ma lalo nei.
ʻO ka papa inoa o nā mea hoʻohana nui no ke kila G115
| MEA | INOA MEA KŪʻAI | HIʻona |
| lāʻau lima | GER-93 | Core wire transition type electrode, ʻo ka mea nui ʻo 9% Cr-3% W-3% Co-Cu-V-Nb-B, kūpaʻa ka hopena hopena i ka lumi wela, a aia kahi palena. |
| uea GTAW | GTR-W93 | ʻO nā mea nui e like me ka mea i luna, no ka priming, ka hana paʻa a me ka hana maikaʻi |
| Pale kua ʻole ʻo ArgonʻO nā lāʻau GTWA | GTR-E93 | ʻO ke kaula kuʻihao argon arc i uhi ʻia, hiki ke hoʻokuʻu ʻia ka ʻaoʻao hope o ka hoʻopiha argon, ʻoi aku ka maikaʻi o ka hana ʻana i ʻelua ʻaoʻao. |
| SAW uwea | GWR-W93 | Hoʻokumu maikaʻi ʻia ka weld bead, ʻoi aku ka kiʻekiʻe o ka helu ʻike flaw qualification, a paʻa ka hopena. |
| ʻO ka lele | GXR-93 |
Ma ka manawa like, ke hana ikaika nei mākou i nā hoʻololi ʻenehana, ka hoʻāʻo ʻana i nā mea hoʻohana a me ke kaʻina hana me nā ʻāpana mea hoʻohana like ʻole, a ʻimi i nā manawa kūpono no ka loiloi paipu G115 e hōʻoia piha i ka hoʻokō ʻana o nā mea hoʻohana welding i ke kaʻina maoli.
I Pepeluali 2022, ua loiloi ʻo Guangdong Thermal Power Welding Company i kā mākou G115 steel welding rod (inoa huahana: GER-93) no ke kaʻina wili paipu mānoanoa 115mm.
He hōʻike pōkole kēia o ke kaʻina loiloi.
He kiʻi mua ka Kiʻi 1 o nā paipu paipu no kēia loiloi, a me ka nui o ka paipu: φ530×115mm.
Ka hoʻomākaukau ʻana i nā paipu paipu ma mua o ka wili ʻana
ʻO nā kiʻi 2 a me 3 nā hiʻohiʻona kiʻi o ke kaʻina hana kuʻi, ʻo 6G ke kūlana kuʻi, a ua hoʻopaʻa paʻa ʻia nā ʻāpana kaʻina hana e kāna mau limahana hana.
Fig. 4 a me Figure 5 hōʻike i ka weld ma hope o ke kuʻi ʻana, hiki ke ʻike ʻia he palahalaha ka weld bead, kūpono ka wai i hoʻoheheʻe ʻia, a maikaʻi ka corrugation, e hōʻike ana i ka hoʻohana ʻana o ka welding consumables maikaʻi nā kūlana a pau.
Figure 6 hōʻike i ke koena lōʻihi o kā mākou electrode ma hope o ka kuʻiʻana, hiki ke ike i ke koena ma hope o ka welding mea kumu emi, e hōʻike ana i ke ahi maikaʻi kū'ē o ka electrode, i loko o ka wela kūlana kiʻekiʻe o ka welding hiki ke malama mau i ka arc a me ka molten pool state. , kiʻekiʻe ka nui o ka hoʻohana ʻana o kahi electrode hoʻokahi, e pale aku i ka ʻōpala.
ʻO 775 °C ka mahana hoʻomaʻamaʻa wela ma hope, ʻo ka mahana mau no 12 mau hola, He kiʻi schematic ʻo 7 o kēlā me kēia hōʻike hōʻike.
Ua hoʻokuʻu ʻia nā hopena hoʻāʻo o kēlā me kēia laʻana o ka loiloi wili paipu, ʻoi aku ka maikaʻi o ka hana tensile, a ua haki nā papa tensile i ke kūlana o ka metala kumu;He maikaʻi ka hana hoʻopili hopena a aia kekahi palena;Aia ka waiwai oolea ma ka laina;ʻO nā ʻāpana pio i lawe ʻia ʻaʻohe māwae a me nā hemahema ʻē aʻe.Ua ʻoluʻolu nā hopena holoʻokoʻa a kū i nā koi i manaʻo ʻia o ka loiloi.
Inā makemake ʻoe i ʻike hou aku, e ʻoluʻolu e kelepona iā mākou!
E hoʻomau mākou i ka hana ma ke kaʻina hana localization o nā mea hoʻohana welding kiʻekiʻe.No ke kōkua ʻana i ka hoʻolālā ikehu aupuni, ka mālama ʻana i ka ikehu a me ka hoʻohaʻahaʻa hoʻokuʻu ʻana, manaʻolana wau e loaʻa ka manawa e aʻo ai mai nā ʻoihana like ʻole a me nā hoaaloha, a hana pū!
Ka manawa hoʻouna: Dec-01-2022
