Simbi pombikugadzira tekinoroji kusimudzira kwakatanga nekuwedzera kwekugadzira bhasikoro, kuvandudzwa kwemafuta mukati mekutanga kwezana ramakore rechi 19, ngarava mbiri dzehondo dzepasirese, boilers, kugadzirwa kwendege, mushure mehondo yechipiri yekupisa simba bhaira kugadzira, indasitiri uye nekudaro kuvandudzwa kwemafuta uye gasi kuchera uye. chekufambisa, zvinobudirira kutyaira simbi pombi indasitiri mukati kukura mhando, goho uye unhu. Kazhinji simbi mutopota maererano gungano nzira, rakakamurwa musono simbi pombi uye welded simbi pombi mhando mbiri, zvino kunyanya kusuma welded simbi pombi.
Welded simbi pombi ndiko kuti welded simbi mutopota, kugadzirwa kwayo ndechokuti chubhu blank (simbi ndiro uye simbi bhandi) pamwe kupararira kuumba nzira kukotama uye kumonera kupinda anodiwa muchinjikwa-Sectional chimiro uye kukura chubhu chubhu, uye saka. shandisa nzira dzakasiyana-siyana dzekucheka kuti weld weld uye uwane iyo simbi pombi maitiro. Kuenzaniswa nesimbi isina musono pombi, welded pombi ine hunhu hwehupamhi hwepamusoro, kunyanya kurongeka kwemadziro ukobvu, nyore midziyo mikuru, basa diki, kuenderera mberi kwekushanda mukugadzira, kuchinjika kugadzirwa, yakafara chigadzirwa siyana yeyuniti ipapo.
Nzira yekugadzira mapaipi ichagoverwa kuva: SSAW (Spirally Submerged Arc Welding); LSAW (Longitudinous Arc Welding); magetsi kuramba Welding (ERW) matatu.
I. gungano muitiro we spiral simbi pombi zvinenge sezvinotevera
● Raw zvinhu zve spiral simbi pombi ndeye strip coil, welding waya uye flux.
● Usati wagadzira tambo mushure mekuenzanisa, kucheka, kuronga, kuchenesa pamusoro, kutakura uye kubhenda kugadzirisa.
● Iyo weld gap control mudziyo unoshandiswa kusimbisa kuti weld gap inosangana nezvinodiwa zvewelding, uye zvakare iyo pombi dhayamita, yakadzama kumucheto uye weld gap inodzorwa zvakanyanya.
● Mushure mekucheka mune imwe pombi yesimbi, batch yega yega yesimbi pombi musoro wetatu kuti ubate kunze kwakasimba kwekutanga kuongorora sisitimu, tarisa ma mechanic zvimiro zve weld, kuumbwa kwekemikari, kunyungudika, simbi pombi pamusoro pemhando uye mushure mekuongorora kusinga konzerese, ita shuwa kuti iyo pombi. kugadzira nzira inokodzera, inoiswa zviri pamutemo mukugadzirwa.
Maviri, akatwasuka musono akanyudzwa arc welding pombi
Yakatwasuka musono yakanyura arc welded pombi (LSAW) kazhinji inotora ndiro sechinhu, kuburikidza neyakasiyana maitirwo ekugadzira, inotora kaviri-mativi akanyudzwa arc welding uye post-welding yekuwedzera uye mamwe maitiro ekugadzira welded pombi.
Muchina mukuru wekugadzira muchina, pre - kubhenda muchina, kugadzira muchina, pre - welding muchina, muchina wekuwedzera ipapo. Zvichakadaro, kune UO (UOE), RB (RBE), JCO (JCOE) uye ipapo. Iyo ndiro mukati mekugadzira mold inotanga kudzvanywa muU chimiro, saka yakatsikirirwa muO chimiro, uye saka mukati uye kunze yakanyura arc welding, welding kazhinji kumusoro kana kureba kwakakwana kwekuwedzera (Kuwedzera) kunonzi UOE welded pombi, kwete. Kuwedzera inonzi UO welded pombi. Iyo ndiro inokungurutswa Bending shaped, ipapo mukati nekunze yakanyura arc welding inoitwa. Mushure mekugadzira, dhayamita iRBE welded chubhu kana RB welded chubhu pasina kuwedzera. Iyo ndiro inogadzirwa mukati mekurongeka kweJcO-mhando, uye mushure mekucheka, iyo dhayamita inowedzerwa kune JCOE welded pombi kana JCO welded pombi pasina kuwedzera.
Yetatu, yakatwasuka seam yakakwirira frequency welded pombi (ERW) ndeyekuti inopisa yakatenderedzwa coil mushure memuchina wekuumba, uchishandisa chiitiko chemagetsi uye pedo nemhedzisiro yeakakwira frequency ikozvino, saka kuruma kwechubhu kunopisa uye kunyungudutswa, pasi pechiito che extrusion. roller pressure welding kuti uwane kugadzirwa.
