    Please explain that, As per ASME

    Hello, for the combination of PQRs, if a coupon used in the PQR is at least 13 mm, a WPS can be supported using that PQR for the root without limits of base metal thickness (only applies to the root, it is not necessary that said coupon this soldier 100% with the same process).

    Please explain that, As per ASME

    Hello, qw 200.4 (b) for the combination of PQR, the code indicates that you can use a process in a test coupon (PQR) of "at least 13 mm" with the benefit of using it to cover said process at the root to qualify any thickness of base metal (no thickness limits) avoiding table qw 451.1. The welded...

    Impact test ASME b 31.3 ed. 2020

    I interpret that if the temperature is -18 ° C or lower, I must qualify the PQR with impact in welding .... "except" if the consumables are certified with impact requirement at the same or lower temperature. So in my case of SA 333 Gr 6 piping certified at -45 ° C (18J) using an E7018-1...

    I & E range ASME IX

    Good morning, the amperage / voltage range is not essential variable, if it has an impact, you only have to respect your maximum qualified heat-input. PD. to know the heat-input in addition to amperage / voltage you must have the welding speed taken from the PQR.

    B31.3 and Section IX - Impact Testing Procedure Qualification Position

    buenas tardes a todos, en resumen el comité se dio cuenta que la variable que importa para controlar los valores de tenacidad es el Heat-Imput, con realizar la cuenta según formula de ASME IX es suficiente sin que importe la progresión de soldadura. por ejemplo: Si califico un procedimiento en...
