WebAs mentioned above, the first possible thermal method for controlling HAZ hardness is to control the cooling time of the weldment between 800°C and 500°C (1470°F and 930°F). This prevents the generation of hard microstructures. The minimum cooling time ‘t 8/5 ’ or cooling rate for production welding must be specified. Web13 Apr 2024 · Rockwell hardness testing is one of the seemingly easiest tests to perform on the shop floor, in the quality-control department or in the metallurgical laboratory but arguably one of the hardest tests to perform properly. ...
