This video is a job we did to replace the damaged and worn out segments on a circle for a Caterpillar 12M Motor Grader. The grader missed it’s routine maintenance which resulted in quickly worn out circle segments. We need to cut out the worn segments then fit and weld in the new segments. First we mark out and cut out the worn segments using our oxy gas cutting torch. We then carefully measure and fit the new segments and use our 9” inch angle grinder to perfectly align and fit. We then tack weld before fulling welding out both sides of the new segments to the circle. We then grind back the welds using the 9” inch angle grinder before linishing to finish.
In this video we are using:
- Makita 2400W 9” inch Angle Grinder
- WIA Weldmatic 500i Welder
