Hardfacing Strategies to Protect Your Excavator’s Bucket
Choosing the right alloy for your hardfacing application is crucial to extending the lifespan of your excavator’s bucket. The first step is to determine the composition of the base material (the metal surface receiving the weld) and assess the working conditions it will face, such as impact, abrasion, or extreme wear. Once you have selected the most suitable alloy, you can implement a hardfacing strategy that provides optimal protection for high-wear areas.
Effective Hardfacing Strategies for Bucket Protection
1. Dots Hardfacing Pattern
Best for: High-impact environments, such as crushers or heavy-duty excavation.
Application:
- Weld small dots roughly the size of a 2$ coin.
- The distance between dots should be half their diameter (e.g., for a 1” dot, keep a 0.5” gap between dots).
- Arrange dots using a five-dot pattern similar to a dice for even distribution.
Best for: Sidewalls of excavator buckets to trap soil and protect steel surfaces—ideal for urban excavation work.
Application:
- Weld circles approximately 1” in diameter.
- Maintain half-diameter spacing between circles (e.g., for a 1” circle, keep a 0.5” gap between circles).
- Arrange circles in a five-dot pattern for optimal coverage.
Best for: Controlling material flow in the bucket, preventing material loss.
Application:
- For rocky materials, weld lines parallel to the flow direction, spacing them according to rock size.
- For finer materials (sand, soil, small rocks), weld lines perpendicular to the flow to retain material in the bucket.
4. Diamond-Shaped Hardfacing Pattern
Best for: Versatile applications combining the benefits of the lines and circles patterns.
Application:
- Weld lines to form a diamond pattern.
- Adjust spacing based on the size and type of material being handled.
