Welding Notes
· Preheating is recommended for thick or high-carbon base materials.
· Maintain proper heat input during welding.
· Multi-layer welding is recommended for optimal abrasion resistance.
· Avoid excessive dilution with the base metal.
· Slow cooling after welding is recommended to minimize cracking.
· Stringer bead welding technique is recommended for improved wear resistance.
· Excessive heat input should be avoided to maintain hardness performance.
