New technology drives growth of robotic welding

Changes in work materials over the past ten years have driven improvements in welding, many of which are impossible to apply manually, such as laser welding. The manufacturers of everything from mining vehicles to automobiles are using different materials to reduce cost and weight and to accommodate different powertrain solutions. Automotive manufacturers have switched to more high-strength and ultra-high-strength steels, which have metallurgical properties making them stronger, lighter, and more corrosion resistant, yet with high formability and weldability.
