More from Design News: Welding stronger steels create joining challenges

Another one worth reading at Design News...

Advanced high-strength steels are moving into the fast lane of automotive applications, thanks to the growing recognition that they can help engineers reduce vehicle weight and improve crash worthiness. But the extra strength comes at a price: The strength gains that make these steels so desirable also compel designers and manufacturers to consider new welding techniques.

The reason largely boils down to the pinchforce required to hold sheets together for spot welding. Whereas a pinch of 400 pounds will accommodate a typical low-carbon steel, a pinch of 1,400 lbs or more would be needed for the higher-strength steels.
