Inshamake yuburyo bwo gusudira ibyuma

Icya kabiri: inzira yo gusudira

Guhitamo ibikoresho byo gusudira ibyuma bitagira umwanda bigomba gukurikiza ihame rya "homogeneity".

1. Ibyuma bitagira umuyonga Niba inzira yo gusudira yashyutswe kuri 430-480 ° C igihe kirekire hanyuma igakonja buhoro, biroroshye cyane kubyara 475 ° C ubukana, kandi umwanda uzagira uruhare runini.Igikorwa cyo gusudira kirasaba ko habaho umuvuduko muke, gusudira byihuse, nta kunyeganyega, hamwe no kugenzura ubushyuhe buke hagati yubushyuhe mugihe cyo gusudira.Kugirango usudire ibihangano byinshi, icyuma gisudira kigomba kuba inyundo kugirango bigabanye imihangayiko yo kugabanuka.

2. Martensitike idafite ibyuma byatewe nubushyuhe bwa zone hamwe no gusudira imbeho ikonje birakenewe kugirango wirinde ibishoboka byose mugihe cyo gusudira, mubisanzwe ufata ubushyuhe bujyanye mbere yo gusudira (150-300 ° C) no kuvura ubushyuhe nyuma yo gusudira (700-750 °) C) ingamba, gukoresha ingufu z'umurongo munini, nibiba ngombwa, urashobora guhitamo ibikoresho byo gusudira austenitis.

3. Ibyuma bitagira umuyonga Austenitike Ibintu bitera ingaruka zogushwanyagurika no kwangirika kwingingo nizibintu byambere byibanze mugusudira ibyuma bitagira umwanda, urebye ibiranga umubiri, hagomba gufatwa ingufu nke zumurongo kugirango zisudwe, gukonjesha vuba, nubushyuhe buke hagati yabantu bigomba kugenzurwa mugihe cyo gusudira.Haranira kubika ferrite ikwiye mugihe cyo gusudira kugirango wirinde ko habaho ubushyuhe bwumuriro.Mu nganda za peteroli nka reaction ya hydrogenation nibindi bicuruzwa byihariye, umubare wa ferrite (FN) weld wateganijwe neza, mubisanzwe bisabwa 3-10.

4. Otirishiya-icyuma duplex idafite ibyuma ifite icyerekezo gito ugereranije nicyuma cya austenitis;Ugereranije nicyuma cya ferritic, kwinjiza nyuma yo gusudira ni bike, kubwibyo bifite gusudira bihebuje, haba kubishyushya cyangwa nyuma yo gushyuha, kandi nta bisimba byo gusudira bibaho.Nyamara, iyo ushyushye mubushyuhe bwinshi, habaho impinduka zo gukura, kandi ingufu ntoya zigomba gufatwa mugihe cyo gusudira.

5Birasabwa inzira yo gusudira isa na martensitike idafite ibyuma, ariko ubushyuhe bwo gushyuha bugomba kwiyongera.

Icyitonderwa:Igipimo cya AWSA5.9 cyuma cya Optical and Filler Wines hamwe na YB / T5092 Standard for Steelless Steel for Welding iteganya ko isesengura ryimiti ryashushanijwe ryashushanijwe ryashizwe hamwe cyangwa insinga cyangwa insinga zuzuza aribwo bushakashatsi bwonyine busabwa kugirango ishyirwa mubikorwa ryibyo bicuruzwa imiterere.Nukuvuga, imiterere yubukanishi nibindi bizamini, ukurikije ibyo abakiriya bakeneye.
Icyuma kitagira umuyonga electrode GES ikurikirana, inyuguti ya nyuma B mu izina ryibicuruzwa yerekana ikote ry'ubururu, R yerekana ikote ritukura, nka GES-308R igereranya ikote ritukura GES-308, GES-312B igereranya uruhu rw'ubururu GES-312 。
