Use MELD to Join
Don’t Weld, MELD.
MELD offers a unique solution for joining a wide range of metals, including aluminum alloys (even non-fusion weldable alloys!), magnesium, titanium, steel, and nickel-based super alloys, among others. Thanks to the solid-state nature of the MELD process, both thick and thin materials can be joined with little to no distortion, such as plates, bar, tubular members, etc. Unlike fusion welding, which inherently presents multiple safety concerns like molten metal, bright light, fumes, and electricity, MELD for joining is safer and due to its significantly lower power requirements, is a green technology.

MELD is capable of creating traditional joint geometries like butt, lap, and spot, but is also able to create joints in ways that are unique to the MELD process (see image below).
MELD also presents the user with the option to join dissimilar materials, such as copper to multiple refractory metals (Tantalum, Niobium, and Molybdenum), titanium to nickel-based super alloys, nickel alloys to steel, and aluminum to steel.
