Argon alxanka aluminium: maxay yihiin kakanaanta oo ka mid ah

Arrinta ah hababka laga heli karaa ugu alxanka aluminium qaab saafi ah oo Alloys kala duwan arrin khuseeya ee la xidhiidha codsigooda ballaadhan. Mid ka mid ah farsamooyinka caadiga ah loo tixgeliyaa alxanka argon aluminium. Sida caadiga ah welded netermouprochnyaemye Alloys aluminium deformable ee ay farsamo aluminium (marks AD AD1) oo ku salaysan Alloys aluminium iyo manganese (Amts), aluminium iyo magnesium (AlMg). Alloys noocan oo kale ah la doorbidayo ka mid adag-to. Maxaa yeelay, iyagu waxaa loo isticmaalaa, haddii daaweynta kulaylka waxaa suuragal ah in qaab-dhismeedka.

Alumina la xirrira filim madax adkaadeen dushiisa of workpiece ee (TM Al ₂ O ₃ = 2050 ° C), isagoo cufnaanta ka weyn biraha laftiisa. Burburintii filimka xabagta qayb ay ka sumayn qubeyska welded, complicating geesaha xidhiidhka ka. Sidaa darteed argon alxanka aluminium waxaa quman ka dib saarista xabagta farsamo ama saldhig Iagu iyo biraha filler. kakanaanta dheeraad ah oo keena farqi weyn oo u dhexeeya Al barafka (TM = 660 ° C) iyo xabagta.

Marka an argon alxanka la koronto tungsten non-consumable aluminium, talantaalli hadda ah waxaa laga codsadaa. Xaaladdan oo kale, film xabagta waa la burburin ee polarity dambe bar-wareegyada marka koronto ah waa 70% jiilka kulaylka of ARC ah, iyo alaabta - 30% (sputtering dhacdaa).

xoog biraha soo maratay hoos at heerkul ka sareeya, taasoo keeni karta burbur ku laayeen qayb unmelted hoos miisaanka pool Weld ah. dhalaalisa kordhay qulquli Al kordhisaa suurtagalnimada baxsiga ka xididka Weld ah. Si looga hortago marks gubashada iyo Guuldarrooyin Weld, haddii sameeyaa argon technology alxanka yaabaa inay ku lug isticmaalka sameynta dhoobada ah (graphite iyo steel) pads. Cosi, alxanka ama lakabyada bir-hal lakabka hore iyo multi-tollayn.

janjeera An kor u warping of Alloys aluminium waxaa looga guulaysan karaa fulinta alxanka on xaaladaha heerkulka fiicnayn oo dabka kulaalaya xabbadood shaqada. porosity The hydrogen dhacdo Weld, gaar ahaan dareemi Alloys la magnesium, taasi oo ka kululaynta waa la dhimay si T = 150-250 ° C ka hor iyo inta lagu jiro alxanka, iyo nadiifinta buuxa ee geesaha iyo welded silig. Si aan si muuqan dildilaaca kulul, dun waa in aan la ku yaal meel u dhow midba midka kale. Waxa kale oo intaa dheer suurtogal ah ee modifiers gaar ah u qaadidda biraha.

Argon alxanka aluminium ku lug leedahay isticmaalka deegaanka ilaaliya gaseous gaaska argon inert barakiciyay jawiga hawada ka qubeyska Weld iyo qaanso plasma. Khusayso Ar laga yaabaa (fasalka ugu sareeya ama hore). muuqashadii kale oo ilaalin ah - helium, isku dar ah ee helium iyo argon, laakiin markaas socodka gaaska waa la yara kordhay.

Dhexroor nonconsumable koronto tungsten (marka laga reebo saafi ah, ama loo isticmaalo ittrirovannye lanthanised) waxaa loo doortay ku xiran tahay oo dhumucdiisuna waxay soo saarka. Sida wax filler ah u dhaqmo silig alxanka ee fasalada kala duwan, taas oo ku xidhan kooban ee wax soo saarka iyo ku laayeen oo dhumucdiisuna waxay ugu weyn. argon tayo sare leh alxanka gacmihiisa lagu samayn karaa on talantaalli hadda ah (nooc UDG rakibo) la hababka loo baahan yahay, kuwaas oo loo xushay alxanka khibrad leh. bilaabayso waa in ay marka hore bartaan ilo suugaanta, la tilmaamayo ee hababka iyo Gudigga ee alxanka aluminium.
