Hard facing rod for oxy-acetylene welding with utmost abrasion resistance and cutting action.
The special composite rod deposits hard tungsten-carbides uniformly distributed within a bronze matrix.
The tungsten carbide grains that stick out of the surface of the deposit can be considered as very small cutting tools.
Easily applicable by oxyacetylene gas torch.
Especially advantageous for improvising tungsten-carbide-tipped drills (e.g. when Lasticut is applied by torch on a steel pipe or tube, it becomes an excellent stone- or concrete drill).
Also for protecting smooth surfaces with an antiskid layer.
Hardness matrix: 200 HB
Hardness grains: 9 Mohs
Clean and degrease the surfaces very thoroughly by filing or grinding (also the surrounding area!).
Use, if possible, Lastek 12 as base layer for better bonding results.
Adjust the oxy-acetylene torch and use a larger tip size for a broad soft flame with an excess of acetylene.
Flux Lastek 12A can be used if necessary.
Heat the tinned surface to remelt temperature and then direct the flame onto the Lasticut-rod and allow it to melt off.
