If it is temporary and stops the leak, why not...? go ahead

--Good day valued members.
Has any of you gentlemen had any experience in temporary repairs on carbon steel pressure vessel by means of mechanical peening? A steam leak was discovered on a Low pressure Heater (300Kpa) at a nozzle to vessel shell weld interface. It seems to be a pinhole through the weld. Is mechanical peening of the defect area considered to be an acceptable means of closing up the leak temporarily until a proper weld repair can be carried out? And if so, is this type of repair documented in any of the in service inspection and repair standards?
Your input is greatly appreciated.
