Process advantages.

• High joint efficiencies (competitive with riveting and bonding)
• Excellent mechanical properties as demonstrated by fatigue, tensile and bend tests
• Robust process
• Environmentally friendly process
• No fumes
• No porosity
• Energy efficient
• One tool can typically be used for up to 1000m of joint length
• No filler wire
• No gas shielding 
• No welder certification required 
• No grinding, brushing or pickling required in mass production
