DESCRIPTION
VSS-330 is a lime-titania electrode which may form the deposited metal of 15%Cr-35%Ni stainless steel with the perfect structure of austenite. As the weld metal contains high Ni, it ha good acid resistibility and heat resistibility.
APPLICATIONS
Welding of cast iron products such as AlSl 330 and SUH 330 which heat resistibility is required.
INSTRUCTIONS FOR WELDING
- Pay attention to hot cracking because the weld metal becomes perfect austenitic structure and select the welding current as low as possible.
- Avoid the continous welding, and is desirable to keep inter-pass temperature under 150°C.
- Operate crater treatment enoughly.
