TWP61
TWP61 is a complex-carbide flux cored wire electrode used to protect equipment and parts from heavy wear in extreme temperatures.
TWP61 has a unique composition that forms a tight crystalline matrix, and is able to deter heavy wear in temperatures up to 842°F (450°C).
KEY PERFORMANCE
CHARACTERISTICS
- Heavy abrasion resistance.
- High heat resistance.
- Tight crystalline matrix.
- Good corrosion resistance.
Applications
TWP61 can be overlain on carbon steel, manganese base materials and mild or alloy steels. The maximum recommended deposit thickness of TWP68iW 3/8” (9.53mm) in 2 – 3 layers.
TWP61 is used for the installation of wear plate and parts, as well as for hot wear applications such as burner tips, classifier cones and smokestacks.
Welding Procedure
The surface should be free from oil, rust and other contaminants by grinding if necessary. The weld deposit may be applied using stringer or weave beads.
Overlay as per parent material welding procedure for pre/post heat, post weld cooling should be gradual. grinding is possible, the deposit is not machinable or forgeable. Stress releiving (cross-checking) occurs during cooling.
Spool size depends on type of wire and size.
