Hardness Test Method for B31.3 Production Welds
Hardness Test Method for B31.3 Production Welds
(OP)
B31.3 331.1.7 requires hardness testing of production welds and sets the limits for Max Brinell Hardness in Table 331.1.1. I'd prefer to use Brinell testing in accordance with ASTM E10 or E110. I have a supplier that wants to use an ultrasonic portable hardness tester (does not meet ASTM E10 or E110). Does B31.3 specify the required method for hardness testing?
