Profile: Manufacturing Technology, Inc. offers a wide range of inertia & direct drive friction welders from 500 lb. weld force (model 40) to 4,500,000 lb. weld force (model 2000). We are manufacturers of large friction welders in service over the 300-ton capacity. This experience, wide range of friction welder sizes, design resources, research & development & contract welding services for industries with variable or low volume needs, combine to make us a complete friction welding source. Friction welding applications join a wide range of part shapes, materials, and weld sizes. Applications typically friction welded include aircraft and aerospace components, cutting tools, agricultural machinery, automotive parts, oil field pieces, waste canisters, military equipment, spindle blanks and bimetallic materials. Inertia friction welding is a variation of friction welding in which the energy required to make the weld is supplied primarily by the stored rotational kinetic energy of the welding machine. Direct drive friction welding is a variation of friction welding in which the energy required to make the weld is supplied by the welding machine through a direct motor connection for a preset period of the welding cycle. We are an ISO 9001 certified company.
