Habaynta / alxanka
Habka alxanka caadiga ah ee darajadan birta ah waa:
- TIG-alxanka
- MAG-Alxanka Silig Adag
- Alxanka Arc (E)
- Alxanka Laysarka
- Alxanka Arc-ga quusta (SAW)
Markaad dooranayso birta buuxinta, culayska daxalka waa in sidoo kale la tixgeliyaa.Isticmaalka biraha buuxinta alxanka sare waxay noqon kartaa lagama maarmaan sababtoo ah qaabka kabka ee birta alxanka.Kuleyliyaha hore uma baahna birtaan.Daaweynta kulaylka ka dib alxanka caadi ahaan lama isticmaalo.Biraha Austenitic-ku waxay leeyihiin kaliya 30% kulaylka kuleyliyaha birta aan daawaha lahayn.Barta isku dhafka ahi way ka hoosaysaa birta aan daawaynta lahayn sidaa darteed biraha austenitic waa in lagu lingaxo kulaylka hoose marka loo eego biraha daawaha leh.Si aad uga fogaato kulaylka ama gubashada go'yaal khafiif ah, xawaaraha alxanka sare waa in la mariyaa.Taarikada naxaasta ah ee loogu talagalay diidmada kuleyliyaha degdega ah ayaa shaqeynaya, halka, si looga fogaado dildilaaca birta alxanka, looma oggola in ay dusha sare ku fidiso saxanka naxaasta ah.Birtani waxay leedahay iskudhaf aad u sarreeya oo balaadhinta kulaylka ah sida birta aan daawaynta lahayn.Marka la eego kororka kulaylka xun, qallooc weyn waa in la filayaa.Marka alxanka 1.4571 dhammaan hababka, kuwaas oo ka soo horjeeda qalloocan this (tusaale-tallaabo isku xigxiga alxanka alxanka, alxanka beddelka ah ee dhinacyada iska soo horjeeda oo leh laba-V dabada alxanka, meelaynta laba alxanka marka qaybaha ay waaweyn yihiin) waa in si gaar ah loo ixtiraamo.Dhumucdiisuna waxay ka badan tahay 12mm alxanka dabada laba-V waa in la door bidaa halkii laga heli lahaa alxanka dabada-hal-V.Xagasha lagu daray waa in ay ahaataa 60° – 70°, marka la isticmaalayo MIG-alxanka qiyaastii 50° ayaa ku filan.Waa in laga fogaadaa ururinta tolida alxanka.Alxanka tuubada waa in lagu dhejiyaa masaafo aad uga gaaban midba midka kale (oo aad uga gaaban kuwa birta aan daawaha lahayn), si looga hortago qallafsanaan xoog leh, soo gaabinaya alxanka alxanka.Xirmooyinka waa in la shiido ama ugu yaraan ay ka xoroobaan dildilaaca.1.4571 ee la xidhiidha birta alxanka austenitic iyo gelinta kulaylka aadka u sarreeya ee qabatinka si loo sameeyo dildilaaca kulaylka ayaa jira.Qabatinka dildilaaca kulaylka waa la xaddidi karaa, haddii birta alxanka ay ka kooban tahay waxyaabo hoose oo ferrite ah (delta ferrite).Waxyaabaha ku jira ferrite ilaa 10% waxay leeyihiin saameyn wanaagsan mana saameeyaan caabbinta daxalka guud ahaan.Lakabka ugu khafiifsan ee suurtogalka ah waa in la lingaxo (farsamo kuul adag) sababtoo ah xawaaraha qaboojinta sare wuxuu yareeyaa qabatinka dildilaaca kulul.Qaboojin degdeg ah oo la doorbidi karo waa in la hamiyaa marka la alxanayo sidoo kale, si looga fogaado u nuglaanshaha daxalka intergranular iyo embrittlement.1.4571 aad bay ugu habboon tahay alxanka alxanka laysarka (weldability A si waafaqsan wargayska DVS 3203, qaybta 3).Iyada oo ballac alxanka ah oo ka yar 0.3mm siday u kala horreeyaan, dhumucda alaabta 0.1mm looma baahna isticmaalka biraha buuxinta.Iyada oo leh godad alxanka weyn oo la mid ah ayaa la isticmaali karaa.Iyada oo laga fogaanayo oksaydheynta dusha tolayga inta lagu jiro alxanka alxanka laysarka ee lagu dabaqi karo alxanka gacanta dambe, tusaale ahaan Helium sida gaas aan shaqaynayn, tolidda alxanka waxay u adkaysataa daxalka sida birta saldhigga ah.Khatar dildilaac ah oo kulul ee tollaynta alxanka ma jirto, marka aad dooranayso hab lagu dabaqi karo.1.4571 sidoo kale waxay ku habboon tahay goynta fiyuuska laysarka leh ee nitrogen ama ololka oo ogsijiin.Cidhifyada la gooyay kaliya waxay leeyihiin aagag kuleyl yar saameeyay guud ahaanna waa ka madax banaan yihiin dildilaaca yar yar oo sidaas darteed si fiican ayey u qaabaysan yihiin.Marka la dooranayo habka lagu dabaqi karo, geesaha la gooyey fiyuuska ayaa si toos ah loo beddeli karaa.Gaar ahaan, waa la alxan karaa iyada oo aan wax diyaargaraw kale ah la helin.Marka la farsameeyo oo keliya qalabka aan-xawaalka ahayn sida burushka birta, pneumatic-ka iyo wixii la mid ah waa la oggol yahay, si aanay khatar u gelin qulqulka.Waa in la dayacay in lagu calaamadiyo gudaha aagga tolitaanka alxanka oo leh boolal yar yar ama heerkul muujinaya midabyo.Iska caabbinta daxalka sare ee birtaan aan kala go 'lahayn waxay ku salaysan tahay samaynta isku-dhafan, lakabka is haysta ee dusha sare.Midabbada, miisaanka, haraaga dharbaaxada, birta taraamka, spatters iyo wixii la mid ah waa in la saaraa, si aan loo baabi'in lakabka dadban.Nadiifinta dusha sare waxaa lagu dabaqi karaa habsocodyada cadayashada, shiididda, qajaarka ama qarxinta (ciidda silica-free-birta ama muraayadaha)Si loo cadaydo kaliya burushyada birta ah ee aan birta lahayn ayaa loo isticmaali karaa.Soo saarista aagga tolitaanka ee hore loo cadayday waxaa lagu fuliyaa dhuujinta iyo buufinta, si kastaba ha ahaatee, inta badan koollada la jarjaray ama xalalka ayaa la isticmaalaa.Ka dib marka la qaado si taxadar leh oo biyo ah waa in la sameeyaa.
Odhaah
Xaaladda la demiyo maaddadu waxay noqon kartaa wax yar oo magnetizable ah.Iyada oo sii kordheysa qabow samaynta magnetizability-ku wuu kordhaa.

Macluumaadka lagu bixiyey xaashidan xogta ku saabsan xaaladda ama isticmaalka agabka siday u kala horreeyaan alaabtu ma dammaanad qaadayaan hantidooda, laakiin u dhaqan si sharraxaad ah.Macluumaadka, waxaanu ku siinaynaa talo, u hoggaansanaan waayo-aragnimada soo-saaraha iyo sidoo kale annaga.Ma bixin karno dammaanad natiijada ka-hortagga iyo adeegsiga badeecadaha.
