Gusukura imiyoboro ya Argon bikunze kuba ngombwa mu gusudira imiyoboro n'imiyoboro y'ibyuma bidashonga hakoreshejwe uburyo busanzwe nka gaze shielded tungsten arc welding (GTAW) na gaze shielded metal arc welding (SMAW). Ariko ikiguzi cya gaze n'igihe cyo gushyiraho uburyo bwo gusukura bishobora kuba ingenzi, cyane cyane ko uburebure n'umurambararo by'imiyoboro byiyongera.
Mu gusudira ibyuma bitagira umugese bya 300 Series, ba rwiyemezamirimo bashobora gukuraho ikibazo cyo gucika burundu mu gusudira imizi y’imiyoboro ifunguye binyuze mu guhindura kuva kuri GTAW cyangwa SMAW isanzwe bakajya ku gusudira igezweho, mu gihe bakomeza gusudira neza, bagakomeza kurwanya ingese, kandi bujuje ibisabwa mu gusudira (WPS).) bisaba gusudira ibyuma bitagira umugese (GMAW). Uburyo bwiza bwa GMAW bwo gusudira ibyuma bitagira umugese butanga kandi inyungu ziyongereye, imikorere myiza n’uburyo bworoshye bwo kubikoresha kugira ngo bifashe kongera inyungu.
Bitewe n’uko zirwanya ingese kandi zikaba zikomeye, ibyuma bitagira umugese bikoreshwa mu miyoboro myinshi n’imiyoboro, harimo peteroli na gaze, peteroli, na lisansi. Nubwo GTAW yakunze gukoreshwa mu miyoboro myinshi y’ibyuma bitagira umugese, ifite ingaruka mbi zishobora gukemurwa hakoreshejwe GMAW yagutse.
Ubwa mbere, kubera ko hakomeje kubura abasudira b’abahanga, kubona abakozi bazi GTAW ni ikibazo gikomeje kubaho. Icya kabiri, GTAW si yo nzira yihuse yo gusudira, ibi bikaba bibangamira amasosiyete ashaka kongera umusaruro kugira ngo ahuze n’ibyo abakiriya bakeneye. Icya gatatu, bisaba gusudira imiyoboro y’icyuma kidashonga igihe kirekire kandi gihenze.
Gutanga ibitekerezo ni iki? Gusukura ni ukwinjiza gaze mu gihe cyo gusudira kugira ngo ukureho imyanda no gutanga ubufasha. Gusukura inyuma birinda inyuma y'umusudi gukorwamo ogisijeni nyinshi iyo hari ogisijeni.
Iyo uruhande rw'inyuma rudakingiwe mu gihe cyo gusudira umuyoboro w'imizi ufunguye, hashobora kwangirika urufatiro. Uku kwangirika byitwa saccharification kuko bituma habaho ubuso busa n'isukari imbere mu gusudira. Kugira ngo hirindwe ko umusudi ushongeshwa, umusudi ashyira umuyoboro wa gazi mu mpera imwe y'umuyoboro hanyuma agafunga impera y'umuyoboro akoresheje valve yo gusukura. Bakora kandi umwobo ku rundi ruhande rw'umuyoboro. Akenshi banashyira kaseti ku mwenge w'umuyoboro. Nyuma yo gusukura umuyoboro, bakuyemo kaseti ku mwenge maze batangira gusudira, basubiramo inzira yo gukuramo no gusudira kugeza igihe ishashi y'umuzi irangiye.
Kuraho gushyushya. Gusubira inyuma bishobora gutwara igihe kinini n'amafaranga menshi, rimwe na rimwe byongera ibihumbi by'amadolari ku mushinga. Guhindura inzira ya GMAW igezweho bituma ikigo gikoresha imizi idashyushya inyuma mu buryo bwinshi bw'ibyuma bitagira umugese. Gusudira ibyuma bitagira umugese 300 birakwiriye kuri ibi, mu gihe gusudira ibyuma bitagira umugese bigira umugese mwinshi muri iki gihe bisaba GTAW yo gusimbuza imizi.
Gushyira ubushyuhe mu mwanya muto uko bishoboka kose bifasha mu kubungabunga ubushyuhe bw'ibikoresho. Uburyo bumwe bwo kugabanya ubushyuhe ni ukugabanya umubare w'inzira zo gusudira. Uburyo bwa GMAW bugezweho bwo gukoresha amashanyarazi make nka controlled metal deposition (RMD®) bukoresha uburyo bwo kohereza ibyuma bugenzurwa neza kugira ngo burebe ko amazi ashyirwa mu mwanya umwe. Ibi byorohereza umusudi kugenzura pisine yo gusudira, ibi bikaba ari byo bigena uburyo ubushyuhe bushyirwa mu mwanya n'umuvuduko wo gusudira. Ubushyuhe buke butuma pisine yo gusudira ikonje vuba.
Bitewe no kohereza ibyuma mu buryo bugenzurwa no gukonja vuba kwa pisine yo gusudira, pisine yo gusudira ntigira umuvuduko mwinshi kandi imyuka yo gukingira isohoka mu itara rya GMAW neza. Ibi bituma imyuka yo gukingira inyura mu mizi yagaragaye, ikajya hanze mu kirere kandi ikarinda isukari cyangwa ogisijeni munsi ya pisine. Iyi myuka ifata igihe gito kuko ibidendezi bikonja vuba cyane.
Isuzuma ryagaragaje ko inzira yahinduwe ya GMAW yujuje ibisabwa mu gusudira, ariko igakomeza kurwanya ingese nk'uko GTAW root bead welding ibikora.
Guhindura inzira yo gusudira bisaba ko ikigo gisubiramo WPS, ariko guhinduranya nk'uko bishobora gutuma habaho inyungu nini mu gihe no kuzigama amafaranga ku mirimo mishya yo gukora no gusana.
Gusudira imiyoboro y'amazi hakoreshejwe uburyo bwa GMAW bugezweho bitanga inyungu z'inyongera mu musaruro, imikorere myiza no kwigisha gusudira. Ibi birimo:
Bikuraho amahirwe yo gushyuha bitewe n'ubushobozi bwo gushyira hejuru ibyuma byinshi kugira ngo byongere ubugari bw'umuyoboro w'amazi.
Ubudahangarwa bwiza ku gutandukana hagati y'ibice by'imiyoboro miremire n'iciriritse. Iyo icyuma cyoroshye gikoresheje uburyo bworoshye bwo kohereza, ubu buryo bushobora kuziba icyuho cya santimetero 1.5.
Uburebure bw'umurambararo ntibuhinduka uko electrode yagutse kose, ibi bikaba bikemura ingorane z'abakora iyo bagorwa no gukomeza gukoresha electrode mu buryo buhoraho. Uburyo bworoshye bwo gukoresha icyuma gisudira hamwe n'uburyo bwo kohereza ibyuma bungana bishobora kugabanya igihe cyo guhugura abasudira bashya.
Igihe cyo guhindura imikorere kiragabanuka. Insinga imwe na gaze yo kurinda ishobora gukoreshwa mu miyoboro y'amazi, kuzuza no gupfuka imizi. Uburyo bwa GMAW bukoreshwa mu gusohora imyobo bushobora gukoreshwa mu gihe imiyoboro yuzuye kandi igafungwa nibura 80% hakoreshejwe gaze yo kurinda argon.
Ku bijyanye no gukoresha icyuma gishyushya inyuma, ni ngombwa gukurikiza inama eshanu z'ingenzi kugira ngo uhindure neza inzira ya GMAW yahinduwe.
Sukura imiyoboro imbere n'inyuma kugira ngo ukureho umwanda uwo ari wo wose. Koresha uburoso bw'icyuma cyagenewe icyuma kitagira umugese kugira ngo usukure inyuma y'aho ipfundikizo riherereye nibura santimetero 1 uvuye ku nkengero.
Koresha icyuma gishyushya icyuma kitagira umugese cya silikoni nyinshi nka 316LSi cyangwa 308LSi. Silicon nyinshi ituma pisine itoha kandi igakora nk'umuti ugabanya ubushyuhe.
Kugira ngo ubone umusaruro mwiza, koresha uruvange rw'imyuka irinda impanuka yakozwe mu buryo bwihariye, nka heliyumu 90%, argon 7.5%, na dioxyde de carbone 2.5%. Ubundi buryo ni 98% argon na dioxyde de carbone 2%. Umucuruzi w'imyuka irinda impanuka ashobora kugira izindi nama.
Kugira ngo ubone umusaruro mwiza, koresha umutwe w’inyuma n’umutwe w’imiyoboro y’amazi kugira ngo umenye aho umwuka utwikiriye. Umunwa w’inyuma ufite umwuka w’inyuma utanga ubwiza bwiza.
Menya ko gukoresha uburyo bwa GMAW bwo guhindura ikirere kigufi kidafite umwuka wo gusimbuza bituma habaho imyanda mike munsi y’umuyoboro. Akenshi ugenda ushira uko umuyoboro ukonje kandi wujuje ibisabwa ku nganda zikora peteroli, inganda zitanga ingufu n’ibikomoka kuri peteroli.

Tube & Umuyoboro Ikinyamakuru 于 1990 年成为第一本致力于为金属管材行业服务的杂志。 Ikinyamakuru cya Tube & Pipe cyanditswe mu 1990 Tube & Umuyoboro Ikinyamakuru стал пер журналом, посвященным манстрии металлических труб в 1990 году. Ikinyamakuru Tube & Pipe Journal cyabaye ikinyamakuru cya mbere cyihariye inganda z'imiyoboro y'ibyuma mu 1990.Muri iki gihe, iracyari cyo cyonyine cyasohotse mu nganda muri Amerika ya Ruguru kandi yabaye isoko ryizewe cyane ry'amakuru ku bakora mu nganda z'imiyoboro.
Ubu hamwe n'uburyo bwose bwo kubona igitabo cya The FABRICATOR digital edition, byoroshye kubona ibikoresho by'agaciro by'inganda.
Ikinyamakuru The Tube & Pipe Journal cyo kuri interineti ubu kiraboneka neza, gitanga uburyo bworoshye bwo kubona ibikoresho by'agaciro by'inganda.
Shaka uburyo bwuzuye bwo gukoresha ikoranabuhanga rya STAMPING Journal, ririmo ikoranabuhanga rigezweho, uburyo bwiza bwo gukora ibintu n'amakuru y'inganda ku isoko ry'ubukorikori bw'ibyuma.
Ubu ufite uburenganzira bwose bwo gukoresha The Fabricator mu rurimi rw'Icyongereza, ushobora kubona byoroshye ibikoresho by'agaciro by'inganda.
