Weird Surface Defect (Honeycomb like)

Weird Surface Defect (Honeycomb like)

RE: Weird Surface Defect (Honeycomb like)

Aggressive use of a chipping hammer.

RE: Weird Surface Defect (Honeycomb like)

Yup, looks like mechanical damage to me, nothing related to the welding itself.
It could have been there to start with, and you reveled it cleaning up the weld.
But more likely it is either from your weld prep or your weld cleaning.

Most definitely chipping hammer....I bitch about this daily.

RE: Weird Surface Defect (Honeycomb like)

If its a powder it could be "bridge breaking" by an operator?

Thank you all for your reply.

We too suspecting the defect is caused by chipping hammer.

Material had been PMI tested. All chemical composition is accepted as per code.
