Protect Your Construction Equipment (Excavator Bucket & Teeth)

Most construction sites requires the use of excavator to remove the mineral/soil before the actual construction can begin. The abrasion between the mineral and the excavator will result in the wear of bucket as well as the teeth. It is very important for the welder to use the correct welding consumable for the repair and protection of the worn-out parts and areas, this will reduce the down time of the excavator thus increasing the productivity of the excavator.


Most welders have been using the wrong welding electrodes for bucket and teeth repair, welding E7016/E7018 instead onto the worn-out surfaces, below table is a comparison between our hardfacing electrode and E7016/E7018.

Abrasion on the bucket is not as high as compared to the teeth therefore using the low abrasion resistance electrode will do. It will not be cost effective if the welder uses the wrong electrode for the wrong application. As you can see from the picture below, welding the diamond or square pattern on the bucket body will help to trap the soil on the steel surface, forming a layer of clinging earth that will protect the steel surface from further abrasion.

Abrasion on the teeth is much higher therefore it requires high abrasion resistance electrode for the teeth repair. As for the welding pattern, horizontal stringent bead is the best for the teeth. You may also consider welding one more layer on the back side of the teeth where the wear is the most.


Below is a common table for type of wear and how your material is affected. If you wish to know more on hardfacing applications, please feel free to contact us. With the support from our reputable hardfacing manufacturer partners, we are able to advise the best solutions for your repair and maintenance needs.

Hardface your equipment well and correctly to achieve cost and time savings.
