[MW:26577] Re: number of joint repair

Hi,

Number of repairs at one location is project specification requirement, its not addressed in code...

In this case... joint repaired twice and cut for hydrotest and re welded as Golden joint.

while cutting & re beveling the HAZ have been removed, hence its fresh joint ( golden weld) and repaired only once.

basically while repairing due to sudden cooling the hardness in the HAZ will be increased which may leads to cracking...

Regards,

Ram.

Dear expert ,

We have a two times repaired joint , This joints is cutted in order to peform hydrotest and welded again ( golden joints ).

That means this joint is welded 4 times : initial weld , first repair , second repair and golden weld repair .

My question is : ther is any limitation for repair numebr for one joint , if yes please give reference ? the mechanical proprities for HAZ are same after all this repair ?
