The Regulated Metal Deposition or RMD™ process creates a root bead that matches the quality of a Gas Tungsten Arc Welding or GTAW root bead, which is a 5 or 6 mm gap. Unlike GTAW, which requires a high learning curve, the new process enables an apprentice operator to make production-quality welds after only two days of training. The short circuit is anticipated by the welding system, then the welding current is reduced to create a consistent metal transfer. The controlled metal transfer provides uniform droplet deposition, making it easier for the welder to control the puddle. Proving that stable short circuits create only small ripples in the weld puddle, allowing for a consistent tie-in to the sidewall. With a more controllable weld puddle, apprentice operators can easily learn to create uniform, welds. We utilize RMD Welding in many of our components for products such as Steel Tanks and Pressure Vessels. The attached video shows our Welding Department utilizing RMD on a Dual HFKO Enclosed Skid.
