Innovation on Ice: Leister in Arctic Logistics

Author: Chloe Stambaugh, Marketing Associate, Leister Technologies USA

In the extreme environment of Alaska’s North Slope, dependable and environmentally responsible transportation solutions are essential. One such innovation is the development of specialized sled skis made from Ultra-High Molecular Weight Polyethylene (UHMW)—designed to carry loads of up to 100,000 pounds across delicate terrain. This solution is the result of over 15 years of development work, originally initiated by Matt Keogh during his time at Arctic Marine Solutions.

A Major Challenge

Early sled ski prototypes measured 12 feet in length and 30 inches in width, each featuring a bottom deadrise for better glide and a welded 3" × ¾" UHMW runner (or skeg) for enhanced lateral stability. With a 5/8" thick UHMW base, the challenge was welding a material known for its strength and high thermal resistance. 

This is exactly where Leister’s WELDPLAST S6 extrusion welder came into play (comparable to the WELDPLAST 600, as the WELDPLAST S6 is no longer available). It proved critical in manufacturing, repairing, and maintaining the sled skis—providing strong, reliable seams essential for Arctic conditions. Today, fabrication takes place in a full-service shop in Pierceland, Saskatchewan, where these skis are manufactured and refined. 

Efficient, Eco-Friendly Transport 

The UHMW skis offer several key benefits compared to traditional metal skis. Most notably, they significantly reduce drag, lowering fuel consumption and minimizing environmental impact. This is especially important on the tundra, where even the smallest disturbances can have long-term ecological effects.

Thanks to Leister's durable welding tools and plastic welding wire, the lifespan of the UHMW skins is extended—offering a sustainable, cost-effective solution amid increasing raw material prices. 

“Matt is always open to innovative ideas and is never afraid to try what others might not. His feedback and willingness to experiment have made this a rewarding partnership.”

From Concept to Field-Tested Innovation 

Though the current organization did not originate the original sled design, it has played a major role in optimizing and implementing it for modern-day use. Multiple companies now operate with these field-tested UHMW skis—many built or serviced using Leister’s advanced welding equipment.

This story reflects the powerful combination of visionary engineering, hands-on experience, and the right tools. Thanks to Leister’s reliable welding technology, Arctic transport is now more efficient and innovative than ever before.
