Dear all I want some help about designing the power screw in the CNC machine, for my graduating project..
Thanks in advance

Dear all I have a confusion regarding WPS and PQR. I want some help from you.
I have qualified a welding procedure of a butt weld having plate thicknesses of 8 mm http://i.e. (T1=8mm & T2= 8 mm), material is stainless steel (SS 304L) and process is GTAW. I then developed WPS based upon the qualified welding procedure.
Now I have to make two fillet welds of same material having following thicknesses:
Fillet weld 1: T1=28mm and T2=8mm
Fillet weld 1: T1=8mm and T2=2mm
Now my questions are:
1. Should I qualify a welding procedure for fillet welds separately or I can use the same PQR for butt weld to make a fillet weld?
2. If I can use the same PQR for making fillet weld then what welding parameters (voltage, current,wfs etc.) will used in WPS for fillet welds?
