Laser welding techniques are exceptionally well suited for the electrification industry due to the technology’s high speed, low-heat input, precision, and versatility. However, changing the variables of a laser welding application – power, wavelength, travel speed, material, and more – can greatly impact the success of a weld. Laser specialists Dean Langenkamp and Jacob Hay...

Magnetic materials are essential to electric propulsion systems. Key attributes of these materials include resistivity and grain size. Refining grain size increases magnetic saturation limits, and thus allows for lighter, more compact motor designs. Using powder-based processing is one way to achieve fine grain size, but the main methods for doing so are energy intensive,...
