Enhanced Tungsten Adds Hardness To Metal Parts

Enhanced Tungsten Adds Hardness To Metal Parts HITCHES Larry Schmedding owner and founder of Agri-Tool & Supply in Spokane Valley Wash has developed different methods of applying hard surfacing components To improve the process Schmedding and Agri-Tool & Supply researched tested and upgraded equipment lines including stick electrodes wire products powders and TIG torch rods “The old style of applying hard surface was braising ” says Schmedding “We use a tungsten carbide product combined with nickel applied with powder torches Powders are pre-mixed to determine what hardness you want and then you powder braise it on I’ve also got a real good stick electrode made in Germany along with a 045 in diameter tungsten carbide bearing wire Both are excellent products ” He says many people use a solid tungsten carbide chip on the leading edge of their seed drill points An application of tungsten carbide wire provides an excellent backup to put behind the chip keeping wear down Schmedding recommends the hard surfacing applications for farm construction and logging equipment and explains it works on anything that wears He creates online videos posted to the Agri-Tool website teaching hard surfacing techniques “I just show them how to do it and what product to use It’s simple once you learn the basics People can braise it using a welder or powder torch to add it themselves The wire feed is self-explanatory Anyone can do it ” “I’ve used other methods over the last 40 years but this outdoes anything I’ve ever done It doesn’t chip or break off; the nickel binder does a terrific job of holding all the particles in place ” Schmedding prefers customers call for a customized price as the tungsten carbide along with nickel can be somewhat expensive “It’s worth it though ” he says “What it does far outweighs the cost It saves a lot of extra wear Downtime is the invisible profit killer for heavy equipment ” Contact: FARM SHOW Followup Larry Schmedding Agri-Tool & Supply P O Box 612 Spokane Valley Wash 99016 ph 800-321-5460; lnschmed@gmail com; www agritoolsupply com
