Chechipiri: welding process
Sarudzo yesimbi isina tsvina welding zvinhu inofanira kutevedzera mutemo we "homogeneity".
1. Ferritic Stainless simbi Kana iyo welding process ichipisa pa430-480 ° C kwenguva yakareba uye yakatonhodzwa zvishoma nezvishoma, zviri nyore kwazvo kubudisa 475 ° C brittleness, uye tsvina ichaita basa rinokonzera. Iyo welding process inokurudzira yakaderera ikozvino, inokurumidza welding, hapana oscillation, uye yakaderera interlayer tembiricha kutonga panguva multilayer welding. Kuti weld workpieces dzakakora, weld seam inofanirwa kurohwa nenyundo kuderedza shrinkage stress.
2. Martensitic Stainless simbi isina kupisa-yakakanganiswa zone embrittlement uye welding inotonhora makatsemuka inodiwa kudzivirira zvakanyanya sezvinobvira kana welding, kazhinji tora inoenderana preheating usati welding (150-300 °C) uye post-welding kupisa kurapwa (700-750 ° C) zviyero, kushandiswa kwesimba rakakura remutsara, kana zvichidikanwa, unogona kusarudza austenitic welding zvinhu.
3. Austenitic Stainless simbi Izvo zvinofurira zvinhu zvinopisa zvinoputika uye intergranular corrosion ndizvo zvinonyanya kutariswa kune welding yesimbi isina tsvina yakadaro, tichitarisa maitiro ayo emuviri, diki mutsara simba rinofanira kutorwa kune welding, nekukurumidza kutonhora, uye yakaderera interlayer tembiricha. inofanira kudzorwa kana multilayer welding. Edza kuve nechiyero chakakodzera cheferrite kana welding kudzivirira kuitika kwekutsemuka kwekupisa. Muindasitiri yepetrochemical yakadai sehydrogenation reactor uye zvimwe zvigadzirwa, iyo nhamba yemaferrite (FN) yeweld yakatsanangurwa zvakajeka, kazhinji inodiwa 3-10.
4. Austria-iron duplex Stainless simbi ine yakaderera crack tendency ichienzaniswa neaustenitic simbi; Kuenzaniswa nesimbi yeferritic, post-weld embrittlement yakaderera, saka ine yakanakisa weldability, kwete preheating kana post-kupisa, uye hapana mitswe yewelding inogadzirwa. Nekudaro, kana uchidziya pakupisa kwakanyanya, pane katsika kekuti zviyo zvikure, uye diki mutsara simba rinofanirwa kutorwa kana welding.
5. Mvura-yakaomeswa simbi isina tsvina Pamusana pekuoma kwepamusoro, kusimba kusina kunaka uye plastiki yemhando iyi yesimbi, uye yakakura welding yakasara kushushikana, zviri nyore kubudisa kuputika. A welding process yakafanana nemartensitic stainless simbi inokurudzirwa, asi preheating tembiricha inoda kuwedzerwa.
Cherechedza:Iyo AWSA5.9 Yakajairwa yeStainless Steel Optical uye Filler Wires uye YB/T5092 Standard yeStainless Steel yeWelding inotara kuti kuongororwa kwekemikari kwezviyero zvakanyungudutswa zvewaya dzakasanganiswa kana dzakasungwa kana waya yekuzadza ndiko chete kuyedza kunodiwa pakurongwa kwechigadzirwa ichi. mafomu. Kureva, mechanical zvivakwa uye mamwe bvunzo, zvinoenderana nevatengi zvinodiwa.
Stainless simbi ruoko electrode GES series, iyo yekupedzisira tsamba B muzita rechigadzirwa inoratidza bhachi rebhuruu, R inoratidza jasi dzvuku, rakaita seGES-308R rinomiririra jasi dzvuku GES-308, GES-312B inomiririra ganda rebhuruu repiritsi GES-312 .
