[MW:9906] Pneumatic chipping for Slag Removal - Peening

Dear All,
 
Reference UW-39 of ASME Sec.VIII Div.1 for Peening.
 
Query: Whether the pneumatic chipping for slag removal gives a peening effect?
 
There is an interpretation which only states that " Slag removal is not peening". I believe it gives a peening effect as there are continuos impact on the weld.
 
Have somebody came across similar situation or some body have an interpreation for this?
 
Looking forward for responses.
 
Thanks,
Dokku Ajay Kumar
