Cosmetic indention-free welded surfaces Thick-thin aluminum alloy material combinations readily resistance welded
	At least 50% higher shear strength than the same sheet metal welded by other processes
	Weld without being sensitive to surface cleaning!!
	Defect and porosity-free microstructures; Weld alloys presently considered non-weldable!

Focused Current Resistance Welding (FCRW) improves properties of welded structures

New IWSL patent-pending welding technology helps increase the strength and durability of welded structures significantly

• Innovative methods of focusing weld current in resistance welding
• Cooling the heat-affected zone (HAZ) during and after welding by water cooled copper to minimize softening
• HAZ hardness values are at least 50% higher
• Weld quality is not sensitive to surface cleaning prior to welding
• Higher strength non-weldable aluminum alloys are now weldable
