Can be used both downhand and out of position, although the flat position is preferred.
Wearshield BU 30 produces a crack-free wear-resistant deposit with a hardness of 31-38 HRc (295-350 HB) depending on dilution and number of layers. It is particularly suitable under conditions of moderate abrasion and friction, combined with resistance to impact. Ideally suitable for APLs involving rolling, sliding and metal-to-metal wear. It may also be used as a final overlay on parts which need to be machined or as a build-up layer for other hardfacing materials.
Build-up with moderate hardness to resist shock and metal-to-metal wear, as in rolling and sliding. Can be used as underbase for other hardfacing deposits or as a final overlay on parts to be machined or forged Unlimited layers with proper preheat, interpass temperatures and procedures. Use on mild and low alloy steels.
Typical Applications
Build-Up: shovel and bucket lips, pump impellers and housings, pulveriser plows, and mill hammers
Hardfacing: trunnions, tractor rolls, cranes and gears
Welding Positions
All, except vertical down
