Gukonjesha neza (gukonjesha umwuka cyangwa gukonjesha vuba) bifasha mu gukora utuzu duto duto
bitanga umusaruro mwinshi kandi bigafasha mu kugabanya ingese.
7. Gutunganya ubushyuhe (niba bikenewe)
Bitewe n'ubunini n'urwego, amasahani ashobora kumera neza cyangwa agahinduka ubushyuhe
kunoza ubukomere, ubwuzuzanye, no kudahura n'ingaruka.
8. Gutunganya ubuso
Hakorwa isuku, gukata no gukata ubuso.
Ubuso bw'isahani butegurwa kugira ngo bukoreshwe mu gusiga irangi, guturitsa, cyangwa kugira ngo bugaragare mu kirere.
9. Gukata, Gupima no Kurangiza
Amasahani y'icyuma acibwa ku burebure n'ubugari busabwa.
Gukata impande, kuzinganya no kuzigenzura kugira ngo zihuze n'ubushobozi bwo kuzipima.
10. Igenzura ry'Ubuziranenge n'Isuzuma
Ibizamini bya mekanike (imbaraga z'umusaruro, imbaraga zo gukurura, kurekura), isesengura ry'imiti,
ibizamini by’ingaruka, ibizamini bya ultrasound, n’igenzura ry’ibipimo byemeza ko ASTM A588/A588M yujuje ibisabwa.
11. Gupakira no Gutanga
Amasahani apfunyitsemo ibipimo byo kurwanya ingese (imigozi, ibirinda impande, ibipfunyika bidafata amazi)
kandi byoherezwa hakurikijwe ibyo abakiriya bakeneye.
ASTM A588/A588M ni icyuma cy’ubwubatsi gifite imbaraga nke (HSLA) kizwiho kurwanya ingese mu kirere neza—bikunze kwitwa icyuma kirwanya ingese. Ubushobozi bwacyo bwo gukora ibara rimeze nk’ingese ririnda ingese butuma kiba cyiza cyane gukoreshwa hanze igihe kirekire ariko kitarimo kwitabwaho cyane.
1. Ibiraro n'Ubwubatsi bw'Inyubako
Ikoreshwa mu gukora ibiraro biramba n'ibice by'inyubako bisaba imbaraga nyinshi no gukora neza hanze igihe kirekire.
2. Imishinga y'Ubwubatsi n'Ubutaka
Ni byiza cyane ku mitako y'imbere n'imiterere y'ahantu nyaburanga, bikagira isura igezweho kandi imeze neza.

Ubufatanye buhamye n'ibigo by'ubwikorezi nka MSK, MSC, COSCO, uruhererekane rwa serivisi z'ubwikorezi mu buryo bunoze, uruhererekane rwa serivisi z'ubwikorezi ni byo bikunyura.
Dukurikiza amahame ngenderwaho ya sisitemu yo gucunga ubuziranenge ya ISO9001 mu bikorwa byose, kandi dufite ubuyobozi bukomeye kuva ku kugura ibikoresho byo gupfunyika kugeza ku ngengabihe y'imodoka zitwara. Ibi bitanga icyizere cy'uko imirasire ya H-beams iva mu ruganda kugeza aho umushinga uzabera, bikagufasha kubaka ku rufatiro rukomeye rw'umushinga udafite ibibazo!
1. Ni izihe nyungu z'ingenzi za ASTM A588 icyuma gishyushya ubushyuhe?
Ubudahangarwa bwiza bwo kwangirika mu kirere
Umusaruro mwinshi n'imbaraga zo gukurura
Ikiguzi cyo kubungabunga cyagabanijwe (nta gusiga irangi bikenewe)
Ubusoderi bwiza kandi bushobora gushingwa neza
Igihe kirekire cyo gukora ku bikorwa byo hanze
2. Ese ibyuma bya ASTM A588 bisaba gusiga irangi cyangwa gusiga?
Oya.
Bakora urwego rw’umwimerere rw’uburinzi bwa okiside rugabanya ingese.
Ariko, gushushanya ni ngombwa ku bw'ubwiza cyangwa ahantu hadasanzwe.
3. Ese icyuma cya ASTM A588 gishobora gusukurwa?
Yego.
Icyuma cya A588 gifite ubushobozi bwo gusudira neza hakoreshejwe uburyo busanzwe bwo gusudira (SMAW, GMAW, FCAW).
Gushyushya bishobora kuba ngombwa ku bice binini.
4. Ni gute ASTM A588 itandukanye n'icyuma cya Corten?
ASTM A588 ni icyuma gisanzwe gipima ubushyuhe, mu gihe "icyuma cya Corten" ari izina ry'ubucuruzi.
Byombi bitanga ubudahangarwa bw'ingufu n'isura isa.
5. Ese ASTM A588 ikwiriye ibidukikije byo mu mazi?
Yego, ariko imikorere iterwa n'uko umunyu uboneka.
Ku bijyanye no gukorana mu mazi, gusigaho irangi ryinshi bishobora kongera igihe kirekire.
6. Ese ASTM A588 ishobora kwihanganira ubushyuhe buri hasi?
Yego.
Itanga ubukomere bwiza kandi ikagira ubushobozi bwo gukora neza mu bushyuhe buri hasi.
7. Ese ibyuma bya ASTM A588 bikenera ububiko bwihariye?
Bika byumye kandi bifite umwuka mwiza.
Guhagarara k'ubushuhe bishobora gutera ingese zidahagije mu gihe cy'imvura itangiye.
8. Ese hari uburyo bwo gukata, gukota no gukora ibintu byihariye?
Yego—Amasahani ya A588 ashobora gucibwa hakoreshejwe laser, gucibwa hakoreshejwe plasma, gupfunyika, gusukurwa, no gukorwa hakurikijwe imiterere y'umukiriya.
