DRW™ - Deformation Resistance Welding

What is DRW™?

Deformation Resistance Welding (DRW) is a revolutionary new metal-joining technology that delivers reliable, repeatable welds at significantly lower cost than conventional welding solutions. The DRW process allows the welding of similar and selected dissimilar materials as well.

DRW forms a near instantaneous, full strength, leak-tight weld. Unlike conventional welding methods, DRW heats metal surfaces only to the point of softening followed by rapid, engineered compression of the joint. The process automatically bonds metals and creates solid-state joints through the heating and deformation of mating surfaces. The result is a full thickness, superior, solid-state weld that gives designers new freedom to create lean structural assemblies using tubular components.

What are the benefits of DRW?

The DRW process can reduce cycle time and the cost of making a variety of structures using hollow members. Typically, a manufacturing operation using DRW can realize benefits in the following areas:

• Lower materials and capital cost
• Reduced welding cycle time
• Solid-state weld flexibility
• Geometry-independence
• Automation friendly
• Joining of dissimilar materials and shapes
• Leak tight welds
• A weld that is stronger than the parent metal
• Elimination of tube thinning and porosity
• Extended product service life
• No filler material required
• Localized heat application

What manufacturing areas can use the DRW process?

DRW has broad application to all areas of manufacturing. Because of its unique ability to handle tube-to-tube and tube-to-sheet welding, DRW literally changes the game with regard to any type of tubular product manufacturing.
