AWS E308-16
DESCRIPTION:
a. E308-16 weld metal(19Cr-9Ni)is austenite structure,it has excellent mechanical properties and shows good resistance to intergranular corrosion.
b. It can be used for all position welding with excellent performance:
stable arc,small spatters,good appearance of weld.And also the welding electrode shows good heat-resistance character,not easy to turn red and gas porosity is not produced.
APPLICATION:
It can be used to weld corrosion-resistant 06Cr19Ni10 and 06Cr18Ni11Ti stainless steel structures with working temperature lower than 300 ℃
ATTENTION:
a.Before welding,the welding electrodes should be baked at the temperature from 300-350℃ for one hour.
b.Using stainless steel brush to clean the weld seam,in order to avoid scrap iron entering and affect its quality.
