Fa'atusa auala ma auala uelo o uelo

Faʻafefea ona faʻaalia le vasega o le uʻamea uʻamea: Uila uʻamea e aofia ai carbon uamea mo uʻamea, uʻamea uʻamea mo uʻamea, uʻamea uʻamea, ma isi. u'amea vasega uamea.Mo se faʻataʻitaʻiga H08, H08Mn2Si, H1Cr18Ni9.Mo u'amea uelo maualuga maualuga, fa'aopoopo le fa'ailoga "A" i le pito o le vasega.Mo se faʻataʻitaʻiga H08A, H08Mn2SiA.

E masani ona faʻaaogaina paipa uʻamea uʻamea e vaevaeina i ituaiga e tolu nei e tusa ai ma le faʻagasologa faʻaogaina o loʻo faʻaaogaina i la latou gaosiga.

① Faʻaauau pea o le ogaumu faʻapipiʻi (forge welding) paipa uʻamea: O loʻo faʻaalia i le maualuga o le gaosiga o le gaosiga ma le tau maualalo o le gaosiga, ae o le tuʻufaʻatasiga uʻamea o le sooga faʻapipiʻi e le atoatoa, o le lelei o le uelo e le lelei, ma o mea faʻainisinia atoatoa e le lelei.

②Resistance uʻamea paipa uʻamea: O loʻo faʻaalia i le maualuga o le gaosiga o le gaosiga, maualuga le maualuga o le masini, e leai se manaʻoga mo uʻamea uʻamea ma faʻafefe i le taimi o le uʻamea, itiiti le faʻaleagaina o le uʻamea faavae, ma le faʻaleagaina laʻititi ma le faʻalavelave faʻaletonu pe a maeʻa.Ae ui i lea, o ana mea faigaluega e faʻalavelave, e maualuga le faʻafaigaluegaina o meafaigaluega, ma o tulaga maualuga o manaʻoga o soʻotaga uelo e maualuga foi.

③Arc uelo paipa uʻamea: O lona uiga o le soʻotaga faʻapipiʻi e ausia atoatoa le faʻaogaina o le uʻamea, ma o mea faʻainisinia o le sooga e mafai ona oʻo atoatoa pe latalata i mea faʻainisinia o mea faʻavae.E tusa ai ma foliga o le uelo, e mafai ona vaevaeina paipa uʻamea arc uʻamea i paipa suʻisuʻi saʻo ma paipa uelo silo;e tusa ai ma auala eseese o le puipuiga o loʻo faʻaaogaina i le taimi o le uʻamea, e mafai ona vaevaeina paipa uʻamea arc i totonu o paipa uamea uʻamea arc ma faʻafefeteina paipa uamea.E lua ituaiga o paipa uamea uelo.
