stress relieving

Hi,

We have a reduction of wall thickness for a pipe which originally is 10 mm and now is shows 3 mm, the pressure is 300 psig. The area is 1"X1", the line is stress relieved while installation. Now they will make a weld repair (weld build up). the question does is require stress relieving after this repair ?
