Fa'avae fa'avae mo le filifilia o mea e fa'aaogaina uelo

Mafaufau i mea faʻaletino, mea faʻainisinia ma vailaʻau vailaʻau o mea faʻapipiʻi

1. Uila uʻamea fausaga, e masani ona mafaufau i le mataupu faavae o le malosi tutusa, filifili e faʻamalieina manaʻoga o mea faʻainisinia o mea faʻapipiʻi faʻatasi.

2. Mo u'amea uamea maualalo ma u'amea u'amea maualalo i le va o le uelo so'oga o u'amea eseese, e masani ona filifili consumables uelo tutusa ma le tulaga maualalo malosi o le uamea.

3. Mo uʻamea faʻafefe vevela ma uʻamea uʻamea uʻamea, i le faaopoopo atu i le mafaufau i le malosi, ae ia mafaufau foi i le vaega autu o vailaʻau o le uʻamea uʻamea ma le vailaʻau vailaʻau o mea matua latalata.

4. Pe a maualuga le tuufaatasiga o vailaʻau o mea matua, e pei o le carbon poʻo le sulfur, phosphorus ma isi mea leaga faʻaleagaina e maualuga, e tatau ona filifili se mea e faʻaaogaina uelo malosi.E pei o le maualalo hydrogen ituaiga uelo consumables.

Mafaufau i tulaga faigaluega o le uelo ma le faʻaogaina o le faʻatinoga

1. Faʻamauina vaega i le tulaga o le mamafa o le avega ma le aʻafiaga o le mamafa, faʻaopoopo i manaʻoga e faʻamautinoa ai le malosi faʻamalosi, malosi e maua ai, aʻafiaga faigata, palasitika e maualuga atu manaʻoga.I le taimi lea e tatau ona filifilia i mea e faʻafefeteina maualalo-hydrogen.

2. vaega uelo i ala o faasalalauga corrosive, e tatau ona iloga mai le ituaiga ala o faasalalauga, concentration, vevela galue ma le ituaiga o corrosion (corrosion lautele, corrosion intergranular, corrosion stress, ma isi), ina ia filifili le consumables uelo talafeagai.

3. Pe a galue le uelo i lalo o le ofuina o tulaga, e tatau ona iloa le eseesega i le va o laei lautele poʻo aʻafiaga faʻaofuofu, ofuina intermetallic po o abrasive ofuina, ofuina i le vevela o le potu poʻo le ofuina i le vevela maualuga, ma isi. , ina ia mafai ai ona filifili le faʻaogaina faʻaogaina o le uelo talafeagai.

4. I le maualalo o le vevela poʻo le maualuga o le vevela vaega uelo, e tatau ona filifili e faʻamautinoa o le maualalo o le vevela poʻo le maualuga o le vevela o mea faʻainisinia o mea faʻapipiʻi.

Mafaufau i le lavelave ma uiga faʻatulagaina o vaega faʻapipiʻi, ituaiga faʻapipiʻi faʻapipiʻi, ma isi.

1. foliga faigata po o le mafiafia tele o vaega uelo, ona o lona uʻamea uʻamea i le cooling contraction o le mamafa i totonu e faatupuina e le tele, faigofie e maua ai taʻetaʻe.O le mea lea, e mana'omia le fa'aogaina o mea e fa'aaogaina fa'atasi ma le lelei o le tete'e, e pei ole la'au uelo e maualalo-hydrogen, tootoo uelo malosi maualuga.

2. Mo nisi so'oga e iai ni pi'o laiti, po'o so'oga fa'atasi ma le pulea lelei o le a'a, e tatau ona fa'aogaina mea fa'aoga uelo e sili atu le loloto o le fusi po'o le tu'i.

3. Ona o le taofiofia o nisi vaega uelo faigata ona faamamaina, e tatau ona mafaufau i le faaaogaina o le ele, oxidation ma le suauu tali e le maaleale i mea uelo, e pei o le tootoo uelo acid, ina ia le maua ai faaletonu e pei o porosity.

Manatunatu i le tulaga fa'apitonu'u o le uelo

O nisi o mea faʻaaogaina e faʻaaogaina e naʻo le fetaui mo le faʻapipiʻiina i se tulaga patino, o isi tulaga e itiiti le aoga pe a faʻapipiʻiina, o nisi mea faʻaaogaina e mafai ona faʻafefe i tulaga eseese, o uiga o le tulaga uelo e tatau ona mafaufauina pe a filifilia.

Mafaufau uelo tulaga faigaluega, siosiomaga faagaoioia

1. E leai se DC uelo masini taimi, e tatau ona faʻaoga AC ma DC lua-faʻaogaina mea uelo.

2. O nisi u'amea (e pei o le pearlite vevela-tetee uamea) e manaʻomia ona faʻamaʻi faʻamamafa faʻamamafa togafitiga vevela, ae e ala i tulaga meafaigaluega poʻo ona lava faʻalavelave faʻavae ma e le mafai ona faʻatinoina, e tatau ona filifilia ma le uʻamea faʻavae vailaʻau o 'ese'ese mea fa'aaogaina (e pei o austenitic stainless steel consumables), e mafai ona tuusaunoaina mai togafitiga vevela pe a uma.

3. E tatau ona fa'avae i luga o tulaga faufale, e pei o galuega fa'ato'aga, si'osi'omaga galuega uelo, ma isi i le filifiliga sa'o o mea e fa'aaogaina.

4. I nofoaga e mafai ona faʻaogaina uma eletise faʻafefete ma alkaline, e tatau ona faʻaogaina electrodes uʻamea acidic i le mamao e mafai ai i le vaʻaia o manaʻoga maualuga o eletise uʻamea alkaline mo metotia faʻagaioiga ma sauniuniga faufale.

Mafaufau i le tamaoaiga o le uelo

1. Taumafai e faʻaaoga mea faʻatau uelo taugofie, pe a faʻamaonia le faʻaogaina o le faʻaogaina.

2. E mafai ona faʻaogaina mea faʻaaogaina eseese mo le faʻaogaina muamua ma le lua faʻatasi ai ma manaʻoga faʻatinoga eseese, ma e le tuliloaina le faʻatinoga atoa o mea faʻaaogaina faʻatasi.

Mafaufau i le lelei o le uelo

Mo fausaga o loʻo i ai le tele o galuega faʻapipiʻi, e tatau ona faʻaogaina mea e faʻaaogaina i le mamao e mafai ai pe a maua, e pei o le uaea uʻamea, uʻamea uʻamea uʻamea, uʻamea uʻamea lelei, ma isi.
