Wershada Shiinaha oo jaban oo Tayada Sare leh Tubooyinka Birta Kaarboon ee Toosan
Dulmar
"Ku xakamee heerka tafaasiisha, tus tamarta tayada". Shirkadeena waxa ay ku dadaasho in ay dhisto shaqaale tayo leh oo deggan oo ay sahamisay habraac tayo wanaagsan oo wax ku ool ah oo lagu xakameynayo Tubooyinka Tooska ah ee Birta Kaarboonka. Tayada wanaagsan waa jiritaanka warshadda, diiradda saara baahida macaamiisha waa isha badbaadada iyo horumarka shirkadda
Dhuumaha birta kaarboonka ee alxanka leh, waxaa jira 2 tiknoolijiyada ugu muhiimsan ee loo baahan yahay in la ogaado kuwaas oo ah ERW (alxanka caabbinta korantada) iyo SAW (alxanka dhulka hoostiisa). Tuubooyinka loo isticmaalo tignoolajiyadan labadaba waxaa inta badan loo isticmaalaa warshadaha batroolka ee gaadiidka saliidda iyo gaaska, laakiin dhammaantood waxay leeyihiin faa'iidooyin iyaga u gaar ah, markaa isticmaalku waa nooc ka duwan.
Tuubbada ERW waxay ka samaysan tahay saxan bir ah, waxaa jira hal tol oo alxan ah, sababtoo ah xariiqda alxanka ee tuubada ERW waxay ka timid tuubada hooyada, uma baahnid qulqulka alxanka, markaa hantida mashiinku aad ayey u fiican tahay. Oo sababta oo ah waa sifooyinka waxtarka wax soo saarka sare, qiimaha jaban, badbaadinta alaabta, iyo otomaatig fudud, barbar dhig biibiile SAW, tuubada ERW waa tuubo bir ah oo leh waxqabadka wax soo saarka sare, taasoo keentay tayada iyo waxqabadka xad dhaqaale berrinkii kaydinta saliid iyo gaaska. iyo gaadiidka. Gaar ahaan la soco koritaanka tignoolajiyada, tayada haddii khadka alxanka uu yahay mid aad iyo aad u wanaagsan, iyada oo la adeegsanayo tignoolajiyada cusub, ujeedadu waa in la baabi'iyo walaaca, la jilciyo oo la nadiifiyo qaab dhismeedka, iyo hagaajinta sifooyinka farsamada ee dhameystiran ee kuleylka alxanka ee saameeya aagga. Dhuumaha nooca ERW ma aha oo kaliya alxanka lama kala saari karo, laakiin sidoo kale isku xidhka alxanka ayaa gaaraya 1, kaas oo ogaanaya isku-dhafka qaab dhismeedka aagga alxanka iyo walxaha saldhigga ah.
Tignoolajiyada SAW cufnaanta hadda waa mid aad u sareysa, lakabka qulqulayana wuxuu ka hortagayaa luminta kulaylka degdega ah wuxuuna xooga saarayaa aagga alxanka. Alxanka dhulka hoostiisa ku duugan waxa uu leeyahay tollayn tayo sare leh, wax-soo-saar sare, nal la'aan iyo qiiq yar. Tuubooyinka birta ah ee welded ee arc ayaa si weyn loogu isticmaalaa weelasha cadaadiska, qalabka tuubooyinka, alwaaxyada, tiirarka, dareeraha cadaadiska hooseeya, iyo mashaariicda dhismaha birta. Laakiin warshadaha batroolka ee dalka horumaray, tuubada SAW lama ogola sababtoo ah xadka laftiisa, kaliya Shiinaha SAW tuubada ayaa wali loo ogol yahay warshadaha batroolka oo xaddidan.
Tayada wanaagsan iyo qiimaha macquulka ah "waa mabaadi'da ganacsigeena. Haddii aad xiisaynayso alaabtayada iyo xalalkayaga ama aad qabtid wax su'aalo ah, hubi inaad xor u tahay inaad nala soo xiriirto. Waxaan rajeyneynaa inaan xiriir iskaashi kula sameyno mustaqbalka dhow.
Codsiga
Waxaa inta badan loo isticmaalaa qaybaha xoogga iyo cadaadiska, iyo ujeedada guud uumiga, biyaha, gaaska iyo tuubooyinka hawada.
