For example, welding high strength steel with 100 ksi yield strength to itself would require a filler metal that offers a minimum of 90 ksi tensile strength (and a

Weld Toughness vs Weld Strength WELDING ANSWERS

However, there is a problem in trying to achieve high values for all. For the base metals and filler metals used in steel construction there is an inverse relationship between strength and toughness. As strength goes up toughness goes down and vice versa. The chart below illustrates this relationship.
