WebMar 15, 2013 · Impact toughness is the ability of a weld to permanently deform while absorbing energy before fracturing, specifically when stress is applied rapidly—typically, in under one second. In simpler terms, it’s how much rapid-impact energy a weld can take before it cracks. Impacts can come in the form of natural elements, such as wind or ...
