DESCRIPTION
VSS-312 is a lime-titania type electrode which is gives 29%Cr-9%Ni. As the weld metal has high ferrite structure, its crack resistibility is excellent. It is used for welding of dissimilar metals and underlaying welding of hard surfacing.
APPLICATIONS
Welding of dissimilar metals such as stainless steel to mild steel and low alloy steel. Welding of stainless clad steel. Under-laying of hard surfacing.
INSTRUCTIONS FOR WELDING
- Choose the welding current as low as possible to prevent cracking of plate.
- it is necessary to preheat the plate at 200°C and over in the case of welding of special steel such as high alloy tool steels.
