--Dear all
I need to make a WPS as per ASME SEC IX & Construction Code is ASME B31.3
PQR : 12" 42 THK
Material : SA335 P22
Process : GTAW + SMAW
Actual Filler Wire Used in PQR : 3.2 mm Dia Rod ( Amps : 100 ~ 125 , Volts : 23 ~ 26 , Travel Speed : 10 ~ 15 Cm / Min )
But in our site we are using 2.4mmm , 3.2 mm , 4.0 mm Dia Filler Rods
I want to make a WPS mentioning Current , Volt , Travel speed for this 2.4 mm & 4.0 mm Rod also .
What basis and Which clause I can get consequent A , V & TS ?
By below clause we can support our WPS but cant get the value for A , V & TS .
(i) 404.3 Change in Size of Filler metal is Non Essential Variable
(ii) 409.8 Change in I & E Range is an Non Essential Variable
(iii ) 409.1 Heat input increase in Supplementary Essential Variable . My case no need Impact Testing
