ER308L Welding Wire (ISO SS308L)

ER308L welding wire suitable for extra-low carbon stainless steel and it has excellent performance of resistance to intercrvstalline corrosion. It is widely used for welding structures of facilities of synthetic fibre industry, fertilizer industry and petrochemical industry that fabricated by 00Cr19Ni10 stainless steel. Also it can be used for welding 0Cr188Ni10Ti stainless steel structures, which work temperature below 300℃.

Welding Position: F, H, HF, OH, V

Type of Current: DCEP

Notices:

  • Keeping the package of the wire in good condition before welding.
  • To avoid welding defects the shield gas should be pure particularly no moisture in it.
  • The surfaces to be welded must be cleaned away impurities of oil contamination, moisture and the region of groove with 10mm around must be lustered.
  • The flowrate of the shield gas should be 20L-25L/minute and arc length in welding should be 4mm-6mm.
  • Mechanical properties, crack resistance and appearance of the weld metal are affected by heat input in welding so should pay more attention to it.
  • The welding conditions mentioned above for reference only and it is better to do a welding procedure qualification according to project before put it into formal welding.
