Hardness Test
Hardness Test
(OP)
Hello All,
i'm quite new in welding issue.
Currently i'm trying to do hardness test without destructing the parts. Hardness at 3 zones need to be verified ( weld zone, HAZ and base material)
Can you suggest the best way and what machine shall i use to check the hardness?
Thank you in advance.

The advantages of the 2 systems I mentioned are they are both portable and both widely recognized hardness test equipment.
I concur with metengr, you need qualified procedures and personnel..

Both Rockwell and Vickeers will leave macro surface indentations. Equotip (or some similar comparable equipment) should suit.
Have you no traveler or quality documents which control which method should be used?

Since I'm in middle of doing feasible study on hardness test,I prefer to go details.
Document did give some recommendation on what to use however I want to know details.and which are the best method.
Thanks for all suggestions☺

All require a decent surface finish anyway for example polished the surface with a portable grinder/flapper - I'd recommend King Brinell. Also depends what it is your testing?
