Flame Hardening Burner Configuration
Flame hardening torch arrangement is a precise setup of individual gas burners for rapid heating of specific component zones. It requires exact control of travel speed.
Physico-chemical mechanism of action
Flame hardening burner arrangements use several individual gas burners focused on specific component zones. These burners produce rapid, uniform heating via a controlled gas flame. The travel speed of the fuel gas mixture affects the temperature and hardness development in the material.
Metallurgical relevance & risks in welding
Correct arrangement and control of flame hardening burners is critical for even hardness distribution. Inaccurate alignment or excessive travel speed can lead to uneven hardness, cracks, or distortion. This increases the risk of welding defects and reduces component service life.
Workshop practice & instructions
Flame hardening burner arrangements require precise geometric alignment. Control fuel gas travel speed accurately to achieve the desired hardness. A typical travel speed is 10–20 cm/s. Monitor temperature and burner-to-workpiece distance closely and adjust for specific materials and application conditions.
