Essential variable
An essential influencing variable is a parameter in the welding process whose change requires a new procedure qualification. It directly affects the mechanical properties of the weld.
Physicochemical mechanism of action
A key influencing factor is a parameter in the welding process whose change requires a new procedure qualification. It directly affects the mechanical properties of the weld.
Metallurgical relevance & risks in welding
Changing a key influencing factor can lead to significant changes in the mechanical properties of the weld. This can result in cracks, reduced toughness, or increased susceptibility to hot cracking.
Workshop practice & action instructions
If a key influencing factor changes, a new procedure qualification is essential. This includes checking the mechanical properties of the weld, such as strength and toughness. It is important to observe the specific values and temperatures specified for the selected welding process and base material.
