Thermal distortion tendency during cutting
Thermal distortion tendency in cutting is the uneven heat input and dissipation during the cutting process, leading to part deformation. It requires special cutting strategies.
Physical-Chemical Mechanism of Action
Thermal distortion tendency during cutting results from uneven heat input and dissipation in different areas of the material. This leads to local stresses that become locked in and cause deformation.
Metallurgical Relevance & Risks in Welding
Thermal distortion tendency can lead to component deformation and uneven stress distribution. This increases the risk of cracking, especially at cut edges. Inaccuracies in the heat pattern or cutting technique can cause additional distortion and component defects.
Workshop Practice & Instructions
To minimize thermal distortion tendency, take the following measures:
• Use even heat input through optimized cutting techniques.
• Keep the material firmly supported to avoid uneven stresses.
• Regularly check and adjust cutting speed and heat pattern.
