WEARSHIELD® BU stick electrode is ideal for build-up of carbon or low alloy steels for parts that will be machined/forged or before application of a hardfacing product. Typical applications include build-up of shovel/bucket lips, pump impellers/housings, pulverize plows and mill hammers OR hardfacing of trunnions, tractor rolls, cranes and gears. IT can be welded in flat & horizontal positions with unlimited layers (given proper preheat, interpass temperatures and procedures).

Features

• Build-up with moderate hardness to resist shock and metal-to-metal wear, as in rolling and sliding
• Can be used as under base for other hardfacing deposits or as 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
