Mabaadi'da aasaasiga ah ee xulashada alaabta alxanka

Tixgeli sifooyinka jireed, sifooyinka farsamada iyo ka kooban kiimikada walxaha alxanka

1. Qalabaynta birta qaab-dhismeedka, guud ahaan tixgeli mabda'a xoogga siman, dooro inaad buuxiso shuruudaha sifooyinka farsamada ee alaabta alxanka wadajirka ah.

2. Birta kaarboonka yar iyo birta daawaha hoose ee u dhaxaysa isgoysyada alxanka ee birta aan la mid ahayn, guud ahaan dooro alaabta alxanka ee u dhiganta heerka hoose ee birta.

3. Wixii birta kulaylka u adkaysta iyo alxanka birta ah, marka lagu daro tixgelinta xoogga, laakiin sidoo kale tixgeli isku-darka kiimikada ugu weyn ee birta alxanka iyo kiimikooyinka kiimikada ee walxaha waalidka ayaa ku dhow.

4. Marka isku-dhafka kiimikada ee walxaha waalidka, sida kaarboon ama baaruud, fosfooraska iyo wasakhda kale ee waxyeellada leh ay sarreeyaan, waa inay doortaan alaabada alxanka iska caabbinta dillaaca xooggan.Sida alxanka nooca hydrogen hooseeyo.

Tixgeli xaaladaha shaqada ee alxanka iyo isticmaalka waxqabadka

1. Qaybaha welded ee kiiska culeyska firfircoonida iyo culeyska saameynta, marka lagu daro shuruudaha si loo hubiyo xoogga xajinta, xoogga wax soo saarka, adkaanta saameynta, caaggu waa shuruudo sare.Waqtigaan waa in lagu doortaa walxaha alxanka ee hydrogen-ka hooseeya.

2. Qaybaha welded ee warbaahinta daxalka ah, waa in laga soocaa nooca warbaahinta, xoojinta, heerkulka shaqada iyo nooca daxalka (daxalka guud, daxalka intergranular, daxalka stress, iwm), si ay u doortaan ku haboon alxanka ahama.

3. Marka alxanka uu ku shaqeeyo xaaladaha xirashada, waxaa lagama maarmaan ah in la kala saaro xirashada guud ama saameynta, xirashada intermetallic ama xirashada abrasive, xirashada heerkulka qolka ama xirto heerkul sare, iwm. , si loo doorto alaabta alxanka ee ku habboon.

4. In heerkulka hoose ama heerkulka sare qaybaha alxanka, waa in ay doortaan si loo hubiyo in heerkulka hoose ama heerkulka sare sifooyinka farsamo ee alaabta alxanka.

Tixgeli kakanaanta iyo sifooyinka qaabdhismeedka qaybaha alxanka, nooca wadajirka ah ee alxanka, iwm.

1. Qaabka isku dhafan ama dhumuc weyn oo ka mid ah qaybaha welded, sababtoo ah birta alxanka ee qaboojinta qaboojinta cadaadiska gudaha ee ay dhaliso waaweyn, fudud si loo soo saaro dildilaaca.Sidaa darteed, waxaa lagama maarmaan ah in la isticmaalo alaabooyinka alxanka leh ee iska caabbinta dildilaaca wanaagsan, sida usha alxanka nooca-hydrogen hooseeya, usha alxanka adag ee sare.

2. Kala-goysyada qaarkood ee leh jeexjeexyo yaryar, ama kala-goysyada leh xakamayn adag ee xididka dhexgalka, alxanka alxanka leh qoto dheer ee fiyuuska ama dhexgalka waa in la isticmaalo.

3. Sababo la xiriira caqabadaha qaar ka mid ah qaybaha alxanka adag in la nadiifiyo, waa in la tixgeliyo isticmaalka miridhku, oxidation iyo falcelinta saliidda ma aha mid xasaasi u ah walxaha alxanka, sida ul alxanka acid, si aanay u soo saari cilladaha sida porosity.

Tixgeli booska bannaan ee alxanka

Qaar ka mid ah alaabooyinka alxanka ayaa kaliya ku habboon alxanka meel gaar ah, jagooyinka kale ayaa waxtarkoodu yar yahay marka alxanka, qaar ka mid ah alaabooyinka alxanka ayaa awood u leh inay ku alxaan meelo kala duwan, sifooyinka booska alxanka waa in la tixgeliyaa marka la dooranayo.

Tixgeli alxanka xaaladaha shaqada, jawiga shaqada

1. Ma jiro munaasabadaha mashiinka alxanka DC, waa in la isticmaalo AC iyo DC walxo laba-isticmaalka alxanka ah.

2. Qaar ka mid ah birta (sida birta kulaylka u adkaysata pearlite) waxay u baahan yihiin in ay noqdaan daawaynta kulaylka kaalmaynta cadaadiska post-weld, laakiin xaaladaha qalabka ama caqabadaha qaabdhismeedkeeda oo aan la fulin karin, waa in lagu doortaa saldhigga kiimikada ee birta alxanka kala duwan (sida austenitic ahama alxanka isticmaalka), waa laga dhaafi karaa daaweynta kulaylka ka dib.

3. Waa in lagu saleeyaa shuruudaha goobta dhismaha, sida hawlaha goobta, deegaanka shaqada alxanka, iwm.

4. Meelaha laga isticmaali karo electrodes alxanka acidic iyo alkaline labadaba, electrodes alxanka acidic waa in la isticmaalo ilaa inta suurtogalka ah marka la eego shuruudaha sare ee alxanka electrodes ee farsamooyinka hawlgalka iyo diyaarinta dhismaha.

Tixgeli dhaqaalaha alxanka

1. Isku day inaad isticmaasho alxanka qaaliga ah, waase haddii la dammaanad qaadayo waxqabadka isticmaalka.

2. Alaabta alxanka ee kala duwan ayaa loo isticmaali karaa alxanka aasaasiga ah iyo kuwa sare oo leh shuruudo waxqabad oo kala duwan, oo aan si buuxda u soconin wax-qabadka buuxa ee alaabta alxanka oo keliya.

Tixgeli waxtarka alxanka

Qaab dhismeedka leh culeyska shaqada alxanka weyn, isticmaalka alxanka waxtarka sare leh waa in loo adeegsadaa sida ugu fog ee suurtogalka ah marka la heli karo, sida siliga alxanka, usha alxanka budada birta ah, usha alxanka ah ee hufan, iwm.
