Ubuhanga bwa Tube Weld

Umwuga wa Tube Weld Ikoranabuhanga ryerekanwe

Ibisobanuro bigufi:

Ku isonga ryibi bishya ni tekinoroji yacu ya Submerged Arc Welding (SAW), uburyo bwatoranijwe bwo gusudira mu buryo bwuzuye. Iri koranabuhanga ryemeza neza, kuramba no gukora neza, bigatuma biba byiza ku nganda zishingiye ku miyoboro myiza yo gusudira.

Ibyiza bya sosiyete

Iyi sosiyete iherereye mu mujyi wa Cangzhou, mu Ntara ya Hebei, yabaye umuyobozi mu gukora imiyoboro isudira kuva yashingwa mu 1993. Uru ruganda rufite ubuso bwa metero kare 350.000 kandi rufite imashini n’ikoranabuhanga bigezweho kugira ngo bitange umusaruro- ibicuruzwa byo mu rwego byujuje ubuziranenge mpuzamahanga. Hamwe n'umutungo wose wa miliyoni 680 z'amafaranga y'u Rwanda n'abakozi 680 bafite ubuhanga, isosiyete yiyemeje kuba indashyikirwa mu bice byose by'imikorere yayo.

Kumenyekanisha ibicuruzwa

Kumenyekanisha tekinoroji yacu yihariye yo gusudira imiyoboro yo gusudira, yateguwe byumwihariko kugirango ishobore gukenerwa ibisabwa byingutu ya arc gusudira imiyoboro ya gaze. Ku isonga ryibi bishya ni tekinoroji yacu ya Submerged Arc Welding (SAW), uburyo bwatoranijwe bwo gusudira mu buryo bwuzuye. Iri koranabuhanga ryemeza neza, kuramba no gukora neza, bigatuma biba byiza ku nganda zishingiye ku miyoboro myiza yo gusudira.

Abahanga bacugusudiraikoranabuhanga ntiritezimbere gusa uburinganire bwimiterere yimiyoboro ya gaze, inanonosora inzira yo gusudira, igabanya igihe cyo gukora kandi igabanya ibiciro. Twunvise akamaro ka sisitemu ya gazi ya gazi, kandi ibyo twiyemeje mubuziranenge byemeza ko ibicuruzwa byacu bishobora kwihanganira ibyifuzo bikenewe kubyo basabye.

Mugihe dukomeje guhanga udushya no kunoza ikoranabuhanga ryo gusudira, turagutumiye kwibonera kwizerwa no gukora byubuhanga bwacu bwo gusudira imiyoboro. Twizere ko tuguha umuyoboro mwiza wo gusudira wujuje ibyifuzo byawe byihariye, ushyigikiwe nubumenyi bwimyaka myinshi no kwiyemeza guhaza abakiriya.

Ibyiza byibicuruzwa

1. Kimwe mu byiza byingenzi byo gukoresha arc gusudira arc gusudira mu gusudira imiyoboro ya gaze karemano nubushobozi bwayo bwo gutanga umusaruro mwizatube weldhamwe nudusembwa duto. Uburyo bwo gusudira arc bwarohamye butuma bwinjira cyane hamwe nubutaka bworoshye, bifite akamaro kanini kugirango habeho ubusugire bwimiyoboro ya gaze gasanzwe.

2. Automatisation ya arc welding yo mumazi irashobora kongera umusaruro no kugabanya amafaranga yumurimo nigihe cyakazi.

Ibura ry'ibicuruzwa

1. Ingaruka imwe yingenzi nigiciro cyambere cyo gushiraho, gishobora kuba kinini bitewe no gukenera ibikoresho kabuhariwe hamwe nabakoresha ubuhanga.

2. Inzira ntishobora guhinduka nkubundi buryo bwo gusudira, bigatuma idakwiranye na geometrike igoye cyangwa ibikoresho bikikijwe n'inkuta.

3. Iyi mbogamizi irashobora guteza ibibazo mubikorwa bimwe na bimwe, birashoboka ko byavamo gahunda ndende.

Ibibazo

Q1. Gusudira Arc Welding ni iki (SAW)?

SAW ni uburyo bwo gusudira bukoresha electrode ikomeza kugaburirwa hamwe nigice cya granular fusible flux kugirango irinde gusudira kwanduza. Ubu buryo bukora neza cyane kubikoresho byimbitse kandi bikwiranye numuyoboro wa gazi karemano.

Q2. Kuki SAW ikundwa kumiyoboro isudira?

SAW tekinoroji itanga kwinjira cyane hamwe nubuso bworoshye, nibyingenzi muburyo bwimiterere yaumuyoboro wizungurukaikoreshwa mubikorwa byumuvuduko mwinshi nko gutwara gaze gasanzwe.

Q3. Ni izihe nyungu zo gukoresha tekinoroji yo gusudira yabigize umwuga?

Tekinike yihariye yo gusudira ituma ubuziranenge buhoraho, kugabanya ibyago by inenge no kunoza imikorere rusange yibicuruzwa byasuditswe, ari ngombwa mu nganda zangiza umutekano.

Q4. Nigute isosiyete yawe yemeza ubwiza bwibikorwa byo gusudira?

Isosiyete yacu yubahiriza ingamba zihamye zo kugenzura ubuziranenge kandi ikoresha abatekinisiye babishoboye bahuguwe mu buhanga bugezweho bwo gusudira, harimo na SAW, kugira ngo buri gicuruzwa cyuzuze umutekano uhamye ndetse n’imikorere.

Mbere: Umurongo wizewe wumuriro kugirango uhuze ibyifuzo byawe byumutekano
