Hardfacing
Hardfacing is essentially making the surface of a material more resistant to abrasion, wear, impact or corrosion depending on the requirements. This is done by layering complex alloys on common metals using the process of Gas Metal Arc Welding (GMAW), Flux Core Metal Arc Welding (FCMAW) or Plasma Transfer Arc Overlay Welding (PTAW). It is significantly more feasible to overlay common metal such as case iron or mild steel with hardfacing alloys rather than having the entire composites made from it.
Bossong Engineering has considerable expertise and capacity in hardfacing using both Metal Arc and PTA overlay process. Over many years we have developed our robotic systems to perform hardfacing. The robots provide precise and uniform metal deposits on the base metal.
Product uniformity resulting from consistent overlay thickness, fusion and heat input provides a predictable surface life. This enables plant operators to predict maintenance with more certainty and reduces the possibility of equipment damage, unnecessary plant shutdown and inefficiency. Our experience has enabled us to determine the overlay geometry that substantially improves impact and abrasion resistance whilst maintaining effective penetration for every application.
We specialise in 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.
Development:
We maintain ongoing research and development programs to investigate and develop new materials, processes and equipment. These programs have been responsible for considerable improvements in tool life, particularly in severe conditions. We work in conjunction with our clients to provide an ongoing solution to their requirements.
