Dear experts,
we are doing welding in a vessel of joint nozzle to dish with reinforcement pad(pipe thick 10mm(32inch), dish thik 20mm & RF pad 20mm) the weld detail in drawing shows bevel(55 degree) followed with fillet(10mm). All are P1 material.
In my question : the total weld metal deposit is 50mm in a joint(40mm CJP & 10 Fillet)
code says above 38mm groove weld for P1 material PWHT is mandatory and also says groove & fillet exceed 26mm in 2inch pipe PWHT is required.
Now we will do PWHT or not in a particular joint. If not kindly tell the reason.
