Applied standards

  • AWS: ER -308

Characteristics – applications: 

  • VD – 308 is the  rustless steel-coated welding wire.  Used for  welding MIG (protective gas – Ar) or making a paste wire for TIG welding.
  • Suitable for welding rustless steel with grades 201, 304 and other rustless steel grade having Cr and Ni content of 18~21% and 9~ 11 %, respectively. The product is widely used in chemical industry, food industry, medical equipment and instruments, civil structures, etc.
  • Welding to repair kinds of high-carbon steel that other electrodes cause them to be cracked.
