Nhungamiro kune welding electrodes kubva kuEng-Weld

Elekitirodhi inonyanya kuve waya yesimbi yakavharwa. Kazhinji, inofanira kugadzirwa nezvinhu zvakafanana mukati muzvarirwo uye kuumbwa kune simbi iri welded, uye pane zvakasiyana-siyana zvezvinhu zvinopinda mukusarudza iyo electrode chaiyo yepurojekiti yako. Nepo Shielded metal arc welding (SMAW) kana 'stick' maelectrodes achibatika uye ave chikamu cheweld, mamwe maelectrodes akadai seaya anoshandiswa muTIG welding haabatike, zvichireva kuti haanyungudike uye anogara akaparadzana kubva kune weld, mukati mamiriro ezvinhu aya kushandiswa kwetsvimbo yewelding inodiwa.

At Eng-weld, tinoziva kuti kusarudzwa kwe electrode yakarurama kunokosha kana zvasvika kune simba re weld, bead quality, kuderedza splatter uye kuchenesa.

Cellulosic electrodes

Cellulosic electrodes maelectrodes emagetsi akafukidzwa mujasi rine organic zvinhu. Kazhinji, inenge 30% yehuremu hwekuputira ndeye cellulose. Zvisinei, kune dzimwe nyika pasi rose mapepa emapuranga nehupfu hwehuni zvinogona kuwedzerwa pakuputira kuitira kuderedza huwandu hweselulosi yakachena.

Izvo zvakasiyana-siyana zvinokonzerwa nemagetsi mu electrode zvichaora mu arc, zvichiita carbon dioxide, carbon monoxide uye hydrogen, imwe neimwe iyo inowedzera tension mukati me arc ichigadzira arc yakasimba uye yakaoma. Nekuda kweizvi, cellulosic electrode inogona kupinda kusvika 70% kudzika kupfuura maelectrodes anowirirana ane maitiro akafanana aripo.

Kazhinji inogadzirwa neyakaonda kana yepakati ukobvu coating, nepo ichi ichigadzira slag, iyo inogona kucheneswa mushure mekuita welding yapera, inogona kutungamira mukurasikirwa kukuru kwe spatter. Nekudaro, nekuda kwekuvhara gap kuzadzwa, vertical down welding uye kugona kwekupinda kwemhando iyi ye electrode yakanaka kwazvo.

Iwo makuru maficha eCellulosic Electrodes ndeaya:

• Kupinda kwakadzika;
• Kugona welding vertically downwards;
• Iwe unokwanisa weld simbi ine yakanaka mechanical properties;
• Iyo weld pool yakagadzirwa idiki.

Low Hydrogen Electrodes

A low hydrogen electrode inonyanya kushandiswa Shielded metal arc welding (SMAW) ine hunyoro husingasviki 0.6%, kana ichienzaniswa neyakajairwa 4-6% mwando inowanikwa mucellulosic electrodes.

Semitemo, maelectrode ehydrogen epasi akadai seE7018 stick electrode anopa mushandisi mazinga akaderera e spatter akasanganiswa nearc yakatsetseka, yakagadzikana uye yakanyarara. Aya maficha anoita maelectrode aya sarudzo yakanaka kune vane ruzivo welders kana vanotanga kudzidza navo. Hunhu hweaya maelectrode esimbi anozadza anopa welder yakanaka arc control uye kuderedza kudiwa kwe post-weld kuchenesa.

Kusiyana nemamwe maelectrode, akadai seE6010 kana E6011, yakaderera hydrogen electrode inopa yakanakisa mitengo yekuisa uye yekupinda, ichibvumira welding opareta kuti awedzere simbi yeweld mujoinhi chero nguva, nekudaro ichiwedzera kusimba kweweld uku panguva imwe chete ichidzivirira kukanganisa weld. kushaya fusion semuenzaniso.

Izvo zvakakosha zveLow Hydrogen Electrodes ndezvi:

• Kupinda kwakanaka;
• Deposition yakanaka;
• Kunyarara arc maitiro;
• Low spatter levels;
• Kusanganiswa kwakanaka.

Mild Steel Electrodes

Semutemo wezvigunwe, maelectrode esimbi akapfava anopa arc yakanyarara uye yakagadzikana, inopa kupinza kwakaderera kunoita kuti ive yakakodzera kuvharika maburi uye kushanda nemahwendefa matete. Kune zvakadaro, marudzi akasiyana-siyana emagetsi esimbi akapfava, imwe neimwe ine zvimiro zvakasiyana zvishoma izvo zvinoita kuti ikwane zvirinani kune akasiyana maapplication.

Semuyenzaniso, giredhi 6013 ibasa guru, rakapfava simbi electrode inopa kupinza kwakadzika, uku ichichengeta arc yakatsetseka uye yakagadzikana. Iyo arc yeiyi electrode inogadziridzwa nyore nyore, ine yakanaka bead kutaridzika uye yakaderera spatter, yakasanganiswa ne nyore slag control ye vertical-down welding.

Nepo iyo 7018 arc welding tsvimbo zvakare yakapfava simbi electrode, yakagadzirwa kuti isimbise yakakwirira-tensile kabhoni-simbi simbi tsvimbo iyi inowanzo shandiswa mukugadzira welding nekuda kwekutsemuka-resistant zvimiro zveweld. Zvichakadaro zvichaburitsa huwandu hukuru hwe slag, zvichiita kuti dzisakodzere vertical-down welding.

Elekitirodhi yesimbi yekupedzisira yatichatarisa ndeye 6011. Iyi electrode inogoneka uye yakadzika inopinda inokupa arc yakatsetseka uye yakagadzikana, inoshandiswa kubatanidza simbi dzakapfava dzakabatiswa uye mamwe masimbi alloy alloy. Kupfekedzwa kwayo kunoburitsa arc ine simba uye yakadzika inopinda mukati, nepo slag layer yakatetepa uye inobviswa nyore.

Stainless Simbi Electrodes

Sezvimwe nemamwe maelectrode atawona pamusoro, maelectrode esimbi asina tsvina anouya zvakare mumhando dzakasiyana-siyana, imwe neimwe yakasiyana zvishoma pane yekupedzisira.

Pano, tichave tichitarisa magiredhi matatu akasiyana eStainless steel welding electrodes, 308, 309, uye 316, uye paunofanira kuashandisa.

Kana uri kushanda nemhando 301, 302, 304, 305, uye akakanda alloys CF-3 uye CF8, saka isu tinokukurudzira kuti ushandise 308L, kusanganisira ER308LSi welding electrodes. Aya maelectrode esimbi asina tsvina akanyatsokodzera kushandiswa pamasimbi asina austenitic, asi pamashandisirwo akaita semuindasitiri yemagetsi emagetsi, tingakurudzira 308H, sezvo iyi kabhoni electrode yakakwira ichipa kuramba kuri nani kune tembiricha yekushandisa.

Paunenge uchibatanidza yakaderera kana yakapfava simbi alloy kusimbi isina tsvina unofanirwa kushandisa 309L, kusanganisira ER309LSi. Izvi ndezvechokwadi zvakare kana uchijoinha simbi dzisina tsvina dzisina kufanana, semuenzaniso, 409 kune pachayo kana ku304L isina tsvina. Pamusoro peizvi, ivo vanofanirwa kushandiswa kujoinha 309 base simbi.

Kana zvasvika pakushanda ne316L uye 316 base simbi, uye iwo akakandwa akaenzana, CF-8m uye CF-3M, unofanira kungoshandisa 316L, kusanganisira ER317LSi sesimbi yako yekuzadza.

Mamwe 308L maapplication anogona kutsiviwa ne309L sesimbi yekuzadza sezvo asingade molybdenum, kusiyana ne316 kana 316L maapplication anoda molybdenum, uye nekudaro haugone kutsiva 309 pa316.

Yakajairika mashandisirwo eakasiyana Stainless simbi emagetsi anosanganisira:

• Bellows;
• Heat exchangers;
• Zvikamu zvevira;
• Majoini ekuwedzera;
• Ndege dzinopisa dzakawanda;
• Heating element tubing;
• Yakarukwa skrini welding yekupisa tembiricha yekugadzirisa zvicherwa.

Kugadzirisa uye Maintenance Electrodes

Sezvataona pamusoro, pane zvakawanda zvakasiyana-siyana zvemagetsi zviripo. Imwe neimwe ine zvimiro zvakasiyana zvishoma uye saka basa rakasiyana uye rakasiyana. Paunenge uchiita chero basa rekugadzirisa uye rekugadzirisa unofanirwa kuve nechokwadi chekuti electrode yauri kushandisa ine zvivakwa zvaunoda.

Kutanga, simbisa kuti simbi ndeyei yauchange uchigadzirisa kana kuchengetedza. Ipapo, iwe unofanirwa kuona kana iwe uchida universal electrode kana maelectrodes ane chaiwo hunhu. Kana uchinge waunganidza ruzivo rwese urwu, unokwanisa kutanga kupinza, kana ukasadaro, uye ukashandisa electrode isiriyo weld yako inogona kutadza kana kuti unogona kupisa nesimbi yauri kushanda nayo.
