Applications / Features
Welding rod (tube) with Fe based filled with crushed fused tungsten carbide. Rod for oxy-fuel overlay welding on attachments, components and tools exposed to extremely abrasive wear and heavy impact, sliding and percussive stress.
The workpiece surface must be free of scale, rust, oil and grease and free of old loose residues and contamination. A uniform preheat of 300°C – 400°C throughout the cross-section must be ensured. The rod should not be melted in the centre of the flame.
The gas flame should have a slight excess of acetylene during application.
