Re: [MW:23099] CRACK IN ANGLES , An interesting topic and more interesting issue!

In first step, engineers should investigate and analyse the effect of such cracks in a complete manner. Certainly it needs the complete package of data about observed cracks and their characteristics and effects. 

The decision of using those materials with or without any reinforcement is not a concern of  En 10163. You have to enter the world of FFS (Fitness For Service).

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.
