Dear Friends,
Could anyone pl. advice or guide us as we wanted to weld corrosion resistant overlay of Inconel 625 on AISI 4140 on a used sub sea equipment in the oil and gas sector , where in the application demands severe Tensile and cyclic loads on the component . The overlay shall be of approximately 4~5mm on a 100 mm thick section .
The vendor has submitted us two procedures with pulsed GMAW (Auto ) welding process having with and without PWHT . When we referred the procedure with PWHT we found that the procedure is qualified (at 540 degreeC @ soaking time 2hrs and rate of heating 150 degree C/Hr)
can anyone help me out to send the literature with and without PWHT
Best regards
venu
