Friction welding solutions for the Construction and Agriculture industries

Friction welding is used extensively in the Construction and Agricultural industries because the welds are of forged quality, with a 100% butt joint weld throughout the contact area. This creates a bond strong enough to handle the high stress and torque required of heavy machinery components including hydraulic piston rods, rear axles, and gears.

How MTI is making a difference in the Construction and Agricultural Industry

MTI has extensive experience developing welding solutions for the construction and agricultural industry. Friction welding is used extensively in the agricultural industry because the welds are of forged quality with a 100% butt joint weld throughout the contact area. The bond is strong enough to handle the high stress and torque required of heavy machinery components. These costs can be lowered by replacing expensive, total forged parts with forged end welded to bar or tube stock without a reduction in quality. An example of this is hydraulic piston rods. These have similar-size ends but vary in rod diameter and length. Standardized ends can be welded to the required-size rod, reducing component costs as well as physical inventory requirements.

Why friction welding is vital for Construction and Agriculture applications

Component costs can be significantly reduced by replacing expensive, totally-forged parts with parts using forged ends welded to bar or tube stock. This can be done without a reduction in quality by using friction welding. For example, the hydraulic piston rods used extensively in construction and agriculture equipment have similar-sized ends, but vary in the rod length and diameter. Instead of stocking expensive forged components in a variety of different diameter and length configurations, we can friction weld standardized ends to the required rod size by using standardized stocked diameters and lengths of bar or tube stock. This reduces component costs as well as physical inventory requirements. Other applications include front axle yoke shafts, rear axles, drive shafts, and gears.
