This allows it to absorb more impact.

Furthermore, it can also add to the lifespan of a part, making it resist more actions.

Excavator Bucket Rebuilding and Hardfacing

Because of their nature, excavator and loader buckets undergo the wear-and-tear process faster.

Excavator Bucket Hardfacing

Performing hardfacing can allow them to be more durable and longer-lasting! You can apply it on both the interior and the exterior of the buckets for rebuilding, restoring, or enhancing.

Hardfacing Electrode Number

The numbers on the electrode have meanings – they’re not just a bunch of random numbers.

Hardfacing Electrode Number

Comprised of a letter and a 4 or a 5-digit number, here are their meanings:

  • Letter (Prefix E means that it’s an arc welding electrode)
  • First two (2) digits (of a 4-digit number) and first three (3) digits (of a 5-digit number) determines the tensile strength (at the minimum).
  • Third (3rd) digit (of a 4-digit number) and the fourth (4th) digit of a (5-digit number) is a sign of the welding position.
  • The last number is what describes the type of coating that you can use with the electrode.

Before purchasing an electrode, make sure that you know your hardfacing machine well. Using a different or an incompatible electrode can mess up the workpiece.
