This video is a job we did for repairing a blade on a Caterpillar 140M Motor Grader. The blade has started to wear through so we are fabricating, fitting and FCAW welding on a “skin” plate to the grader blade. First we need to cut to size the bisalloy plate using an oxy-lpg gas cutting torch. We then fit the skin to the grader blade, tack weld in place before welding the skin to the blade using flux cored (FCAW) wire. We also cut and weld on wear plates to the sides where the blade is prone to wearing out quicker. We finish it off with some hardfacing to the tops of the welds to give it a longer life.
