Kerf tolerance class
The kerf tolerance class indicates how precisely a thermally cut part must be manufactured. It specifies which deviations in angles and straightness are tolerated.
Physical-Chemical Mechanism of Action
The cut gap tolerance class defines the permissible geometric deviations of thermally cut components. These tolerances include angular tolerances and straightness that can arise from the manufacturing process.
Metallurgical Relevance & Welding Risks
A tolerance class that is too high can lead to inaccurate cut gaps, which poses risks to the strength and behavior of the component under load. Conversely, tolerances that are too low can complicate the manufacturing process and increase production costs.
Workshop Practice & Action Instructions
When welding, it is important that the cut gap tolerance class is maintained. This can be achieved by precise measurement and control of the geometric deviations. If you have questions about the correct tolerance class, you should contact the component manufacturer or the applicable standard.
