The Charpy V-Notch test is the welding industry’s most common method of measuring a weld’s toughness and involves multiple steps — from preparing a test plate to cutting and baking sample blanks, adding a notch to the specimen and more.

Filler metals undergo rigorous testing to ensure they provide proper impact toughness to endure rapid loading, extreme temperatures or other stressors.
