Friction welding is a popular choice in the construction and agriculture industries due to the exceptional strength of the bonds. As the welds are of forged quality, with a 100% butt joint weld throughout the contact, they can 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 industries.

As industry leaders in joining solutions technology, MTI has developed innovative welding solutions specifically for the construction and agriculture industry. Friction welding is used extensively in this sector as the welds are of forged quality with 100% butt weld throughout the contact area and the bond is strong enough to handle the high stress and torque required of heavy machinery components.

To reduce costs MTI have developed a technique where expensive, total forged parts can be replaced with forged ends which are welded to a 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. Standardised 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 standardised ends to the required rod size by using standardised 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.
