RE: Embedment Plate Welds

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Good Question.  I remember years ago (about 20) I had to test a lot of studs on a project.  Swat them with a 4 lb. Hammer.  A ring or a thud was the test.  A thud got them bent over and knocked off.  Occasionally bent over a stud that ringed to verify the weld.  Very scientific, but I guess adequate according to the boss at the time.

 I recall a List post that addressed "field testing" bent anchor bar/headed studs welds to embedment plates with a hammer and some muscle. If the weld failed, then you obviously knew that the weld was NG. Is there a more formal or standard process (ASTM, etc.) available for field testing these welds?


As always,
Thanks in advance
