Gedhi vharafu raw material Stainless simbi ndiro welding tsvimbo

Gedhi vharafu raw material Stainless simbi ndiro welding tsvimbo Iyi yakajairwa Stainless simbi ndiro welding tsvimbo kutsanangurwa classification, tekinoroji zviyero, nzira dzekuyedza uye kuyedzwa zviyero uye rumwe ruzivo rwakabatana. Iyi chiyero inoshanda kune Stainless simbi electrode yearc welding. Maelectrode cladding simbi akadaro anofanirwa kunge aine anopfuura 10.50% chromium uye yakawanda iron kupfuura chero chinhu. Zvinoenderana nekuumbwa kwesimbi yakasanganiswa, mhando yewelding core, welding chinzvimbo uye mhando yewelding ikozvino, iyo welding tsvimbo haifanirwe kunge iine hurema hwakaita sekutsemuka, mabubble, masara uye kudonha kubva izvo zvinokuvadza weld quality, sezvakaratidzwa muTable 1 uye Tafura. 2. 1. Theme pfungwa uye kushandiswa munda Uyu mwero Stainless simbi ndiro welding tsvimbo kutsanangurwa classification, unyanzvi mwero, nzira dzokuedza uye bvunzo zviyero uye mamwe mashoko ane hukama. Iyi chiyero inoshanda kune Stainless simbi electrode yearc welding. Maelectrode cladding simbi akadaro anofanirwa kunge aine anopfuura 10.50% chromium uye yakawanda iron kupfuura chero chinhu. 2 Reference Standards GB223.1 ~ 223.70 Nzira dzekuongorora kemikari yesimbi uye aruminiyamu alloys GB1954 - kuyerwa kweiyo microstructure yemukati muwelding yechrome-nickel low alloy simbi GB2652 Tensile bvunzo nzira yewelding uye cladding simbi GB 4334.5 Stainless corrosion mahwendefa - Stainless corrosion mahwendefa - nzira ye sodium thiosulfate hydrochloride 3 Rudzi uye rondedzero yemhando 3.1 Rudzi uye kutsanangurwa kwetsvimbo yewelding ichapatsanurwa zvichienderana nekuumbwa kwesimbi yakasanganiswa, mhando yewelding core, welding chinzvimbo uye mhando yewelding ikozvino. 3.2 Model Specification yegadziriro nzira Tsamba "E" inoratidza electrode, uye nhamba mushure me "E" inomiririra nhamba yezvikamu zvechikamu chesimbi yakanyungudutswa. Kana pane chinodiwa chakakosha chechikamu, chikamu chinoratidzwa nekemikari element chiratidzo mushure mehuwandu. Nhamba mbiri mushure me "imwe" inomiririra mhando ye electrode core, welding position uye welding current type. 3.3 Mienzaniso yezvinorehwa netsvimbo yewelding muchiyero ichi ndeiyi inotevera: ④E502, E505, E7Cr, E5Mo, E9Mo type electrode ichaiswa mune inotevera yakagadziridzwa GB5118 "high alloy Steel electrode" standard, asi yakadzimwa kubva pachiyero ichi. ⑤ Chivakashure chekutanga XX. Inoratidza imwe 15, imwe 16, imwe 17, imwe 25 kana imwe 26. Cherechedza: Full-position welding haikurudzirwi kune electrodes ane madhayamita akaenzana uye makuru kupfuura 5.0mm. 4 Technical Standards 4.1 Tsanangudzo 4.1.1 Tsanangudzo yeElectrode ichazadzisa zvinodiwa muTable 3. 4.1.1.1 Bvumira kugadzirwa kwe3.0mm aperture electrode pachinzvimbo che3.2 electrode uye 5.8mm aperture electrode pachinzvimbo che6.0rnm electrode. 4.1.1.2 Welding rods dzezvimwe zvakatemwa zvinotenderwa kupihwa maererano nechibvumirano pakati peBato A neBato B. 4.1.2 Kureba kwepanoperera electrode kunoenderana nezvinodiwa muTebhurari 4. Tafura 4 Kureba kwekusungirira 4.2 Welding Core 4.2.1 Panofanira kusave nekutsemuka, mabubbles, masara uye kudonha mukati mewelding core ye electrode zvinokuvadza kunaka kweweld. 4.2.2 Iyo welding core paarc inotangira yekupedzisira ye electrode inofanira kutenderedzwa, uye welding core port inofanira kuburitswa kuti ive nechokwadi chekuti arc kutanga kuri nyore. Iyo yakafumurwa core ye electrode inofanirwa kusangana nezvinodiwa zvinotevera: a. Iyo yekunze dhayamita ye electrode haingapfuuri 2.0 mm, uye kureba kweiyo yakazaruka core haifaniri kudarika 1.6mm b. Kureba kwe electrode i 2.5mm uye 3.2mm, uye kureba kweiyo yakazaruka core haifanire kunge yakakura kudarika 2.0mm pamwe nehurefu hweAngle c. Iyo dhayamita ye electrode inodarika 3.2mm, uye kureba kweiyo yakazaruka core pamwe nehurefu Angle haifanire kunge yakakura kupfuura 3.2mm d. Mhando dzose dze electrode aperture pamwe neAngle yedenderedzwa haifaniri kudarika hafu yedenderedzwa. 4.2.3 Nheyo ye electrode ichava nesimba rakakwana rekumanikidza kudzivirira kuparadzwa mukutakura kwakajairwa kana kushandiswa. 4.2.4 Electrode eccentricity ichazadzisa zvinotevera zvinodiwa: a. Iyo yekunze dhayamita ye electrode haifaniri kudarika 2.5rnm, uye eccentricity haifaniri kudarika 7%; b. Diameter ye 3.2mm uye 4.0mm electrode, eccentricity haifaniri kuva yakakura kudarika 5%; c. Iyo aperture ye electrode haifaniri kunge iri pasi pe5.0mm, uye eccentricity haifaniri kuva yakakura kudarika 4%. Nzira yekuverenga ye eccentricity inoratidzwa sezvinotevera (Mufananidzo 1). Mune fomula: T1 -- welding tsvimbo yemuchinjikwa coating layer ** hombe yakatetepa gobvu weld core aperture T2 - diki yakatetepa uye gobvu weld musimboti aperture yeiyo yakafanana muchinjikwa chikamu epidermal layer 4.3 T-joint weld 4.3.1 Weld surface inofanira kuongororwa nemaziso evanhu pasina kutsemuka, mavanga ewelding, welding burls nemaburi emhepo. 4.3.2 Chikamu chemuchinjikwa cheweld chinosangana nezvinodiwa zvinotevera mushure mekupenya nekupinza: a, divi rega rega re weld richabatanidzwa kana kuti kuburikidza nemuchinjiko wemaplate maviri; b.
