Uaea uelo malu puipuia kesi

Fa'ailoaina o le tatou uaea Uila Uila Fa'a'ese'ese, lelei mo ou mana'oga uma.Na atiaʻe i le 1950s, CO2 gas-shielded welding ua avea nei ma se faʻaogaina faʻaogaina metotia, faʻaaogaina lautele i le tele o matata e pei o fale gaosi oloa, gaosiga o masini faufale, faufale, gaosiga o meafaigaluega, alalaupapa, sefulu galuega faufale, fale gaosi oloa, pusa ma gaosiga o va'a mamafa, ta'avale, ma isi mea.

Auina imeli ia matou

Faailoga o oloa

I le taimi nei, o le fausiaina ma le faʻaogaina o le CO2 uaea uʻamea faʻafefeteina o loʻo olaola, ma o nisi o atunuʻu atinaʻe e pei o tatou o loʻo faʻamauina mo le 40-50% o le aofaʻi o mea faʻaaogaina.O loʻo maua le taʻutaʻua i lea aso ma lea aso i le tele o matagaluega, faʻasolosolo faʻasolosolo le faʻaogaina o le arc arc.O se tasi o ona fa'amanuiaga taua o le maualalo o le tau uelo, ma sili atu le tamaoaiga nai lo isi auala uelo.

O le uaea uelo talipupuni kesi e mitamita foi i le maualuga o le gaosiga o le gaosiga ma le maualalo o le eletise, e faʻalelei ai mo galuega faʻapipiʻi maualuga.E matua faigofie foi ona faagaoioia, aua e mafai ai ona uelo i tulaga uma, e aofia ai le uelo i luga.O le mea lea e faigofie ai mo le uʻamea i avanoa vavalalata poʻo itu faigata.

E le gata i lea, uelo fa'atasi ma CO2 uaea uelo fa'afefeteina e ofoina atu le tulaga lelei.Faatasi ai ma le maualalo o le hydrogen i totonu ma le itiiti ifo o le nitrogen, o le uelo e lelei tele le tete'e.E iai fo'i ni fa'aletonu la'ititi pe a mae'a, ma fa'ato'a atoatoa mo galuega fa'auoloina e sili ona ma'ale'ale.O le uaea e ofoina atu foʻi le faʻaogaina ona e talafeagai mo le faʻapipiʻiina o papatusi manifinifi, feololo, ma mafiafia.

I le fa'ai'uga, o la matou Uaea Uila Fa'asa'o o le Gas-Shielded Solid Welding Wire o se fa'aopoopoga taua i lau fa'agasologa o le uelo, ma o le tele o ona fa'amanuiaga e le mafai ai ona fa'ato'ilaloina e isi faiga uelo.Faatasi ai ma le tulaga sili ona lelei, tau maualalo, maualuga le lelei, ma le faigofie o le faʻaogaina, ua vave ona avea ma metotia faʻapipiʻi sili i le tele o vaega.Filifili le mea e sili ona lelei, ma maua i'uga sili ona lelei i la matou Uaea Uelo Uila Fa'asa'o.
