Weld hardness traverse
The weld zone hardness profile shows hardness measurements across the weld, heat-affected zone, and base material. It helps detect unacceptable hardening or softening.
Physical-Chemical Mechanism of Action
The hardness of a material changes during the welding process. In the weld area, different microstructures can form that have different hardness readings.
Metallurgical Relevance & Risks in Welding
Excessive hardening in the joint area can lead to crack-sensitive martensite. Softening can impair the strength and toughness of the material.
Workshop Practice & Action Instructions
Measuring points should be taken across the weld, heat-affected zone, and base material. Hardness readings should be within the specified tolerance limits. If deviations occur, determine the causes and take appropriate measures.
