Re: [MW:23085] CRACK IN ANGLES , An interesting topic and more interesting issue!

Dear Mr. shokri

Thank you for your reply . I prepared the repair procedure according to En 10163 but because of high volume of surface cracks ( in all over the angle surface )  its not possible to use it.

Is it possible to welding a reinforcing bare in such a surface condition without removing of cracks  ?
According to aws d1.1 Engineer can permit it ?

Please see EN 10025-2, 7.5.3. It will refer you to the EN 10163-1 to 3 for permissible surface discontinuity and repair modes.

Dear expert,

I'm recently working in a structural project as welding qc . During fabrication inspection, surface crack was found in angles material used in project ( as bracing ) so i reviewed the mechanical examination reports ( the tests are done according to En iso 10025-2 ) but absolutely mechanical properties and chemical analysis is ok! and that is so interesting to me  .

And after that according to the material examination reports, welding of a reinforcing bare is permitted by the engineer and its more interesting issue for me!

However my question is according to any fabrication standard is it possible to welding on a cracked surface material like that ?

(the depth of cracks are 3 mm in both sides and in all over the angles surface area .) 

Thank you.
