Variables that become critical only when toughness testing (impact testing at low temperatures) is required by the construction code.
The WPS is a step-by-step "recipe" that guides welders in performing specific tasks. It details critical parameters known as , which include: Base Metal: The types of materials being joined. Filler Metal: The specific electrodes or wires used. welding standard asme
