Not the same as a tensile test. 70,000 PSI pull is still 70,000 pounds pull, the charpy test measures the resistance to cracking and failure, and the ability to take stresses, from a sudden impact. Generally, a more ductile weld will absorb more energy, before giving way, than a more brittle weld material.

Jun 21, 2012 · The only mention of welding (base metal, HAZ, and weld metal) in B31.3 is in table 323.2.2 and it says for weld, the test should only be if MDT is below -20F. So technically, it sounds more like a material purchasing issue and not a welding issue, in other words, it looks like the welding of A106B material only requires Charpy if MDT is below ...
welding test dh 36 charpy temperature FAQ: What is Charpy Testing? - TWI
It should be emphasised that Charpy tests are qualitative, the results can only be compared with each other or with a requirement in a specification - they cannot be used to calculate the fracture toughness of a weld or parent metal. TWI is UKAS accredited for carrying out Charpy testing to ASTM E23 and ISO 148, at a wide range of test ...
