Long Life Ground Engagement Tools:
Bossong Engineering has considerable expertise in the robotic hard facing of ground engagement tools. Application to tools used on equipment such as bucket wheel excavators, reclaimers and dredge cutters often provide increased life in excess of 1000% These results have been obtained in conditions of severe abrasion and impact in a wide range of applications.
Product uniformity resulting from consistent overlay thickness, fusion and heat input provides a predictable tooth life. This enables plant operators to predict bucket maintenance with more certainty and reduces the possibility of adaptor damage. Our experience has enabled us to determine the overlay geometry that substantially improves impact and abrasion resistance while maintaining effective penetration for every application.
Weld metal overlays used on ground engagement tools are predominantly nickel based alloys with up to 70% fused tungsten carbide. These materials offer extreme abrasion and impact resistance. Where the combination of extreme abrasion and impact is not present we utilise chrome and titanium carbide based overlays selected to meet the specific application.
Application techniques include Gas Metal Arc Welding (MIG), Plasma Transferred Arc application (PTA) and oxy fuel application where batch quantities preclude robotic programming and fixture costs.
