Miscellaneous Information
If ARM needs added to miscellaneous ground engaging tools at the request of a customer, more ARM is not always better. "Over carbide" is possible, thereby winding up with parts that are fully worn but still have considerable carbide remaining in areas of low material contact. Inspect the parts that have been used in the machine application. Used parts will show material flow patterns. These patterns indicate where ARM beads will be most effective and provide the best return for the customers investment. Piling ARM beads on top of each other is not recommended. The carbide in the lower bead will melt and produce a hard deposit.Production Costs
An exact production rate for applying ARM is difficult to establish because of all the variables. A starting estimate is 740 cm2/hr (291 inch2/hr), running a 2.5 cm (1.0 inch) bead width. The overall rate of usage for hard particles is approximately 2.3 g/cm2 (0.50 ounce/in2). Other items to take into account when determining the final cost are the degree of piece part cleaning required, any pre-bending or heating and the necessity to repaint the finished tips. Estimate the application cost for a given part by filling out Tables 7 through 10. If further information is needed concerning setup, application, or costs of ARM, contact any of the following:
