GMAW Solid Wire AWS A5.18 ER70S-G CO2 Mig Welding Wire
GMAW Solid Wire AWS A5.18 ER70S-g CO2 migsilig alxanka
Codsiyada:
Waxaa loo isticmaalaa alxanka dhammaan noocyada 500MPa qaybaha birta qaab dhismeedka, taarikada qaro weyn iyo dhuumaha qaro weyn, alxanka xawaaraha sare ee 500MPa biraha salka.
Astaamaha:
Siligan GMAW waxa loogu talagalay birta kaarboon heerka Rm 500MPa oo leh gaaska gaashaan ee CO2 ama M21.
Spatter yar, muuqaal qurux badan, hufnaanta meel dhigista sare iyo dareenka porosity biraha alxanka yar.
GOOBTA ALXANKA：PA,PB,PC,PD,PE,PF
NOOCA HADDA/GAAS：DC+/CO2
Fiiro gaar ah:
1. miridhka, saliida, biyaha iyo wasakhda kale ee meesha alxanka ku jirta waa in meesha laga saaraa ka hor alxanka.
2. Qalabka farsamada ee dhammaan biraha alxanka waxaa lagu go'aamiyaa kulaylka, sida caadiga ah kuleyliyaha yar yar wuxuu ka fiicnaan doonaa mid ka weyn.
