Sharaxaada Alaabta
LSAW (Longitudinal Submerged Arc Welding) tuubooyinka birta waa nooc ka mid ah tuubooyinka birta alxanka leh ee lagu garto habka wax soo saarka ee gaarka ah iyo codsiyo kala duwan. Tuubooyinkan waxa lagu soo saaray samaynta saxan bir ah oo u samaysan qaab cylindrical ah oo si dheer loo alxanayo iyada oo la isticmaalayo farsamooyin alxanka arc hoostooda. Halkan waxaa ah dulmar ku saabsan tuubooyinka birta ee LSAW:
Habka wax-soo-saarka:
● Diyaarinta saxanka: Taariko bir ah oo tayo sare leh ayaa lagu doortaa iyadoo lagu saleynayo shuruudo gaar ah, iyadoo la hubinayo sifooyinka farsamada ee la doonayo iyo isku dhafka kiimikada.
● Samaynta: Saxanka birta ah waxa loo qaabeeyaa tuubo cylindrical ah iyada oo loo marayo habab sida foorarid, duubid, ama cadaadis (JCOE iyo UOE). Cidhifyada ayaa horay loo qaloociyay si loo fududeeyo alxanka.
● Alxanka: Alxanka dhulka hoostiisa (SAW) ayaa la shaqeeyaa, halkaasoo fallaadho lagu hayo lakabka qulqulka hoostiisa. Tani waxay soo saartaa alxanka tayada sare leh oo leh cilladaha ugu yar iyo fiyuuska aad u fiican.
● Kormeerka Ultrasonic: alxanka ka dib, baaritaanka ultrasonic ayaa la sameeyaa si loo ogaado cillad kasta oo gudaha ama dibadda ah ee aagga alxanka.
● Balaadhinta: Dhuumaha waa la ballaarin karaa si loo gaaro dhexroorka la doonayo iyo dhumucda gidaarka, iyadoo kor loo qaadayo saxnaanta cabbirka.
● Kormeerka ugu dambeeya: Tijaabooyin dhammaystiran, oo ay ku jiraan kormeerka aragga, hubinta cabbirka, iyo tijaabooyinka hantida farsamada, waxay hubisaa tayada tuubada.
Faa'iidooyinka
● Waxtarka-kharashka: Tuubooyinka LSAW waxay bixiyaan xal-wax-ku-ool ah oo loogu talagalay dhuumaha dhexroorka waaweyn iyo codsiyada qaab-dhismeedka sababtoo ah habka wax-soo-saarka hufan.
● Xoog Sare: Habka alxanka dhererka wuxuu keenaa tuubooyinka leh sifooyin farsamo oo adag oo isku mid ah.
● Saxnaanta cabbirka: Tuubooyinka LSAW waxay muujinayaan cabbir sax ah, iyaga oo ka dhigaya kuwo ku habboon codsiyada leh dulqaad adag.
● Tayada alxanka: alxanka arc hoostiisa waxay soo saartaa alxanka tayada sare leh oo leh fiyuus aad u fiican iyo cilladaha ugu yar.
● Kala-duwanaanshaha: Tuubooyinka LSAW waxaa loo isticmaalaa warshado kala duwan, oo ay ku jiraan saliidda iyo gaaska, dhismaha, iyo biyaha, taasoo ay ugu wacan tahay laqabsigooda iyo cimrigooda.
Isku soo wada duuboo, tuubooyinka birta ah ee LSAW ayaa la soo saaray iyadoo la adeegsanayo hab sax ah oo hufan, taasoo keentay in tubooyinka la taaban karo, kharash-ku-ool ah, iyo tuubooyinka raagaya ee ku habboon noocyo badan oo codsiyada warshadaha ah.

Baakaynta & Rarista
Xiritaanka iyo raridda saxda ah ee LSAW (Longitudinal Submerged Arc Welding) tuubooyinka birta ayaa muhiim u ah hubinta gaadiidkooda badbaadada leh iyo gaarsiinta meelo kala duwan. Halkan waxaa ah sharaxaadda hababka baakadeynta iyo rarida caadiga ah ee tuubooyinka birta ee LSAW:
Baakad:
● Isku-xidhka: Tuubooyinka LSAW inta badan waa la isku xidhaa ama Hal Qayb ayaa lagu xidhxidhay iyadoo la isticmaalayo xadhkaha birta ama birta si loo abuuro unug la maarayn karo oo wax lagaga qabanayo iyo gaadiidka.
● Ilaalinta: Cidhifyada tuubooyinka waxaa lagu ilaaliyaa koofiyadaha balaastiigga ah si looga hortago waxyeello inta lagu jiro safarka. Intaa waxaa dheer, tuubooyinka waxaa lagu dabooli karaa walxo ilaalin ah si looga ilaaliyo arrimaha deegaanka.
Dahaarka Ka-hortagga Daxalka: Haddii tubooyinka ay leeyihiin daahan ka-hortagga daxalka, daacadnimada dahaarka ayaa la hubiyaa inta lagu jiro xirxiridda si looga hortago waxyeello inta lagu jiro maaraynta iyo gaadiidka.
● Calaamadaynta iyo Calaamadaynta: Xidhmo kasta waxa lagu calaamadeeyay macluumaadka muhiimka ah sida cabbirka tuubada, heerka alaabta, lambarka kulaylka, iyo tilmaamo kale oo si fudud loo aqoonsan karo.
● Badbaadinta: Xirmooyinka si ammaan ah ayaa loogu xidhaa sariiraha ama boodboodka si looga hortago dhaqdhaqaaqa inta lagu jiro gaadiidka.
Rarida:
Hababka Gaadiidka: Tuubooyinka birta ah ee LSAW waxa lagu rari karaa iyadoo la isticmaalayo habab gaadiid oo kala duwan, oo ay ku jiraan waddo, tareen, badda, ama hawada, iyadoo ku xidhan meesha loo socdo iyo degdegga.
● Weelasha: Tuubooyinka waxaa lagu soo rari karaa weelasha si looga ilaaliyo dheeraadka ah, gaar ahaan inta lagu jiro safarka dibadda. Weeladaha waa la raray oo la hubiyaa si looga hortago isbeddelka inta lagu jiro safarka.
● Shuraakada Saadka: Shirkadaha saadka ee caanka ah ama sidayaal khibrad u leh maaraynta tuubooyinka birta ayaa ku hawlan sidii ay u hubin lahaayeen badbaado iyo waqti ku habboon.
● Dukumentiga Kastamka: Dukumeenti kastamka lagama maarmaanka ah, oo ay ku jiraan biilasha rarista, shahaadooyinka asalka, iyo waraaqaha kale ee khuseeya, ayaa loo diyaariyaa oo loo gudbiyaa shixnadaha caalamiga ah.
● Caymiska: Iyadoo ku xiran qiimaha iyo nooca xamuulka, caymiska waxaa la diyaarin karaa si looga ilaaliyo dhacdooyinka lama filaanka ah inta lagu jiro safarka.
● Dabagalka: Nidaamyada raadraaca casriga ah waxay u oggolaanayaan soo-diraha iyo qaatahaba inay la socdaan horumarka rarida wakhtiga dhabta ah, iyagoo hubinaya hufnaanta iyo cusbooneysiinta waqtiga.
● Geynta: Tuubooyinka ayaa laga soo dejiyaa meesha loo socdo, iyadoo la raacayo habraac sax ah oo dejinta si looga fogaado burbur.
● Kormeerka: Marka ay yimaadaan, tuubooyinka waxaa laga yaabaa in la maro kormeer si loo xaqiijiyo xaaladooda iyo u hoggaansanaanta qeexitaanka ka hor inta uusan aqbalin qaataha.
Dhaqannada xirxiran ee saxda ah iyo rarida waxay caawiyaan ka hortagga burburka, ilaalinta daacadnimada tubooyinka birta ee LSAW, iyo inay hubiyaan inay ku gaaraan meelihii loogu talagalay si badbaado leh iyo xaalad wanaagsan.
