Welding Notes
· Preheating is recommended for thick or high-carbon base materials.
· Maintain controlled heat input during welding to reduce cracking risk.
· Multi-layer welding is recommended for optimal wear and impact resistance.
· Avoid excessive dilution with the base metal.
· Slow cooling after welding is recommended for heavy sections.
· Stringer bead welding technique is recommended for improved crack resistance.
· Excessive heat input should be avoided to maintain toughness and hardness balance.
