Umuyoboro wa Spiral Welded Arc Welding w'imiyoboro ya Gazi Kamere

Ibisobanuro bigufi:

Gusudira imigozi ni intambwe y'ingenzi mu gikorwa cyo gukoraumuyoboro ushongeshejwe ku buryo bw'uruzigacyane cyaneumuyoboro wa gaze karemanos. Bikubiyemo gukoresha ubushyuhe bwinshi kugira ngo habeho isano ikomeye kandi irambye hagati y'imiyoboro, bitume habaho imikorere yizewe kandi irambye. Muri iyi nkuru, turashaka'Tuzareba mu buryo bugoye imiyoboro ya gaze karemano ikoze mu buryo bwa spiral welded arc welded n'impamvu ari yo'igice cy'ingenzi cy'inganda z'imiyoboro y'amazi.

Kuriumuyoboro wa gaze karemanos, umutekano n'ubwirinzi ni ingenzi cyane. Gusudira imiyoboro bifite uruhare runini mu kwemeza ko iyi miyoboro ishobora kwihanganira imimerere mibi ihura nayo mu gihe cyo kuyikoresha. Uburyo bwo gusudira imiyoboro busaba gukoresha amashanyarazi kugira ngo habeho ubushyuhe bwinshi bushongesha impande z'imiyoboro kandi buyihuze.

Kimwe mu bintu by'ingenzi ugomba kwitaho mu gihe usuka imiyoboro ya gaze karemano ni ubwoko bw'ubuhanga bwo gusudira bukoreshwa.umuyoboro ushongeshejwe ku buryo bw'uruzigas, uburyo bukunze gukoreshwa cyane ni ikoranabuhanga ryo gusudira arc (SAW). Ibi bikubiyemo gukoresha flux y'ibinure, isukwa hejuru y'agace ko gusudira kugira ngo habeho ikirere kirinda ogisijeni n'ibindi bihumanya bigira ingaruka ku isudira. Ibi bituma isudira nziza kandi ingana kandi ifite inenge nke.

Ikindi kintu cy'ingenzi kigomba kwitabwaho mu gihe cyo gusudira imiyoboro ya gaze karemano ni uguhitamo ibikoresho byo gusudira. Ibikoresho byo gusudira bikoreshwa mu kuzuza icyuho cyangwa ibitagenda neza mu gusudira, bigatuma habaho isano ikomeye kandi ihamye. Ku miyoboro isumiye ku buryo bw'uruziga, hagomba gukoreshwa ibikoresho byo gusudira bihuye n'urwego rw'icyuma gikoreshwa ndetse n'imiterere y'ibidukikije aho umuyoboro uhura nabyo. Ibi bituma isumiye ishobora kwihanganira igitutu n'ubushyuhe bigerwaho n'imiyoboro ya gaze karemano.

Uretse ibijyanye na tekiniki mu gusudira imiyoboro y'amashanyarazi, ni ngombwa kandi gusuzuma ubushobozi n'uburambe by'umusudi ukora akazi. Gusudira imiyoboro y'amashanyarazi ikoresha gazi karemano bisaba ubuhanga n'ubuhanga bwo hejuru, ndetse no gusobanukirwa neza imbogamizi zidasanzwe n'ibisabwa muri ako kazi. Ni ngombwa gukorana n'abasudi bafite uburambe kandi bemewe bashobora gukora imisudi yujuje ibisabwa mu nganda.

Muri make, umuyoboro wa gaze karemano ukozwe mu buryo bwa spiral welded tube arc welded ni igice cy'ingenzi mu nganda z'imiyoboro. Bisaba gusuzuma neza uburyo bwo gusudira, ibikoresho byo kuzuza, n'ubushobozi bw'umusudi ukora akazi. Mu kwemeza ko ibi bintu byitabwaho bikwiye, bizashoboka gukora imiyoboro ya gaze karemano ihuye n'ibyo inganda zisaba kugira ngo zigire umutekano, zizewe kandi zikore neza igihe kirekire.
