Ibikurikira, Hangao Tehc (Seko Machinery) azakomeza kugutera kumva ibibazo bishobora kubaho mugihe cyo gusudira no kugufasha gukumira no gukemura ibibazo nkibi.
03 gusudira bishyushye (Crystallsation Cracks muri Welds, imizigo ya Liquefaction muri zone yibasiwe nubushyuhe)
Imitini yo kuvuza ikirere cyane cyane biterwa nibigize imiti, imitunganyirize n'imikorere yibikoresho. Ni biroroshye gukora ahantu hato hamwe cyangwa ubumwe hamwe numwanda nka S na P. Gutandukanya Boron na Silicon bizateza imbere imyuka.
Ikidodo cyoroshye biroroshye gushinga imiterere yinkingi ya Crystal hamwe nubuyobozi bukomeye, bufasha gutandukanya umwanda wangiza nibindi. Ibi biteza imbere gushinga film ikomeza amazi akomeza kandi atezimbere senseri yo guca imva. Niba gusudira bidashyushye kimwe, biroroshye gukora imihangayiko minini ya minini kandi itezimbere ibisekuru byo gusudira.
Ingamba zo gukumira:
a. Subiza neza ibikubiye mubyangiritse S na P.
b. Hindura imitunganyirize yicyuma. Imiterere ibiri yo kwihatira urudomo rufite imbaraga nziza. Icyiciro cya Delta muri Welta kirashobora kunonosora ibinyampeke, gukuraho icyerekezo cyicyiciro cyicyiciro kimwe, kandi iki cyiciro cya Delta kirashobora guhungabanya imbaraga zangiza kandi zitegura ishyirwaho rya firime yimikorere yinyuma.
c. Hindura urubwize ibyuma. Appropriately increase the content of Mn, C, and N in the single-phase austenitic steel, and add a small amount of trace elements such as cerium, pickaxe, and tantalum (which can refine the weld structure and purify the grain boundary), which can reduce the sensitivity of thermal cracking.
d. Ingamba zo gutunganya. Mugabanye kwishyurwa cyane pisine yashongeshejwe kugirango wirinde gushiraho kristu yinkingi yinkingi. Koresha ubushyuhe buto hamwe nigituba gito cyambukiranya. An Igikoresho giharanira gihamye kirashobora kongerwaho mugihe cyo gusudira kugirango ugabanye agace ka pisine yashongeshejwe, kunoza imikorere yakazi yimbunda, no kunoza ubuziranenge.
Kurugero, 25-20 Icyuma gikunze kugaragara mu mibo mit. Birashoboka kugabanya cyane imyanya myiza hamwe nubunini bwibinyampeke byibikoresho byimiterere, ukoreshe uburyo bwo gutanga imbaraga zo mu rwego rwo hejuru, kwinjiza ubushyuhe buto kandi byongera igipimo gikonje cyingingo.
04 ukaranze ingingo zisukuye
Ubushyuhe-Ibyuma Bikwiye Gutezimbere Inyabutumwa Byuzuye Inshingano zo gukumira injiji-ndende Ibyibato-ubushyuhe birasabwa kugira ubushyuhe buke-buke bwo gukumira ubushyuhe buke bwo kuvunika ingingo zisukuye.
05 gusunika binini
Bitewe nububiko buke bwubushyuhe hamwe nububiko bunini bwa kwaguka, uburyo bwo gusudira ni kinini, kandi clamps irashobora gukoreshwa mu gukumira imiterere. Uburyo bwo gusudira bwa atenitique ibyuma no guhitamo ibikoresho byo gusudira:
Icyuma cya Austonike gishobora gusudira na Argon Tungsten Arc gusudira (TIG), argon arc gusudira (mig
Icyuma kidafite imbaraga gifite ubushyuhe buke kubera ko hari aho bishonga hasi, imikorere myiza yubushyuhe, no kurwanya amashanyarazi menshi. Weldrow Ikamba n'amasaro bigomba gukoreshwa kugirango ugabanye igihe cyo guturamo ubushyuhe bwinshi, wirinde imvura yubushyuhe bwinshi, ibuza imihangayiko ya kaburimbo, ukagabanya guhangayikishwa no gucika intege, kandi ugabanye ubushyuhe.
Ibigize ibikoresho byo gusudira, cyane cyane cr na ni allow ibintu, birenze ibyo bikoresho shingiro. Koresha ibikoresho byo gusudira birimo umubare muto (4-12%) wa Ferrite kugirango urwanye neza (gukonjesha, gutontoma bishyushye, guhangayikishwa na ruswa) imikorere ya Weld.
Iyo icyiciro cya Ferrite kitemewe cyangwa kidashoboka muri Weld, ibikoresho byo gusudira bigomba kuba ibikoresho byo gusudira birimo mo, MN nibindi bikoresho.
C, s, p, si, na nb mubintu bisudira bigomba kuba bike bishoboka. NB izatera ibice bikomeye muri Wesen Held, ariko ubwinshi bwa Ferrite muri WeLad irashobora kwirinda neza.
Kubwuburyo bwo gusudira bugomba gutuzwa cyangwa guhangayika-biruhumiwe nyuma yo gusudira, ibikoresho bikubiyemo gusudira mubisanzwe bikoreshwa. Kunywa arc gusudira bikoreshwa mugukuraho isahani yo hagati, no gutakaza cr na ni irashobora kwiyongera no kwimurwa na flux hamwe nintushya mumato yo gusudira;
Kubera ubujyakuzimu bunini bwinjira, hagomba kwitabwaho kugirango birinde ibintu bishyushye hagati ya Weld no kugabanya kurwanya ruswa muri zone yibasiwe. Kwitondera bigomba kwishyurwa kugirango uhitemo insinga yoroshye hamwe nigituba gito cyo gusudira. Insinga gusudira igomba kuba hasi muri si, s, na P.
Ibirimo ferrite mubushyuhe butagira ibyuma ntigishobora kurenga 5%. Kubyuma bya ausitique hamwe na cr na ni ibirimo birenze 20%, muri MN (6-8%) Isumisu rya Alkaline cyangwa itabogamiye mugukoreshwa nka flux kugirango wibeho kandi utezimbere.
Ubururu bwihariye kuri ibyuma bikabije bya siustitique ntabwo yiyongereye cyane si, rishobora kwimura abuvamo urubwite kandi rwishyura kubura amateka yo gutwika.
