Proven Technology

Nova-Tech has developed custom drive/steer wheelsets to meet a wide range of draw bar and load requirements. Wheelsets are used in groups or in conjunction with casters to provide a means to move large parts, tools and equipment throughout the factory for a variety of applications.

Modular Wheelset System (MWS) & Powered Wheelsets

For years Nova-Tech has developed custom drive/steer wheelsets to meet a wide range of draw bar and load requirements. Wheelsets are used in groups or in conjunction with casters to provide a means to move large parts, tools and equipment throughout the factory for a variety of applications.

Nova-Tech has recently developed a family of compact, modular drive/steer wheelsets and controls called the Modular Wheelset System (MWS) that can be easily fitted to existing equipment (e.g. workstands, mobile robot platforms, etc.) to provide greater mobility, flexibility and safety while eliminating the need for forklifts or powered tugs.

Friction Stir Weld (FSW)

Friction Stir Welding (FSW) is a solid state joining process that produces improved joint properties as compared to conventional fusion welding techniques. Fusion welding is characterized by melting of the material, adding a filler rod, and natural cooling to form a weld. A shielding gas is required to protect the weld from contamination. FSW is accomplished at temperatures below the melting point of the material, and does not introducefiller rod nor require shielding gas to form the joint. By its nature, FSW eliminates problems associated with cooling from the melted condition such as porosity, solidification cracking and shrinkage. In comparison, FSW has been found to produce nearly defect free joints.
