    PWHT

    How long should we PWHT to stress relieve a PQR coupon 1" thick that would cover production welding and additional PWHT for any repairs that are needed after the initial PWHT? Thanks moe27

    Heat input and travel speed

    When qualifying a weld procedure we take note of the amps, volts and travel time for each pass. When the coupon is finished we may have travel speeds ranging from 7" to 10" per minute. How do you calculate the travel speed for the WPS, average all the speeds, take a high and a low average or...

    Combining 2 PQRs to write a WPS

    We have a FCAW process PQR that covers a range of material thickness of .187" to 8". If we qualify a coupon using GTAW process using 1/2" thick material or greater we will be allowed to combine these 2 PQRs to write a WPS that covers a root pass and 2 additional fill passes using GTAW and the...

    ASME sec IX WPS & material thickness range

    We need to weld a lift lug onto a block of steel. The lift lug is A516 GR70 1" thick x 6" wide X 8" tall. The block is A517 GR70 6" thick 24"x24" sq and the lug will be a full pen weld centered on this sq block. Which of these 2 material thicknesses must the WPS meet? A WPS that covers a...

    ASME sec IX 409.8 I&E range a Nonessential

    AWS D1.1 has a +/- on the Amps and Volts as an essential variable but with ASME sec IX this is considered a Nonessential Variable. MY questions are; 1) Why is this considered a Nonessential Variable? 2) If welding to an approved ASME sec IX WPS for a FCAW process and the welder is a little over...

    PJP groove welds

    We have a WPS certified to ASME sec IX for welding P1 G1&2 materials with a thickness range on groove welds of .125" to 1.0". Could we use this WPS to weld a 1.25" thick plate onto a 1" plate if the 1.25" plate only requires a PJP groove weld? Regards

    grinding welds before VT inspection

    Structural welding only (not pressure containing welds) No NDE inspection requirements called for other than 100% visual inspection. Question, Is it OK with AWS D1.1 standards for visual inspection to grind on a weld before VT inspection. I have been told that grinding will smear the metal and...

    qualified base metal thickness

    FCAW P1 material to P1. I will be welding a 3/8" thick lift lug (CJP) onto the side of a 2" plate (TEE JOINT). We have a WPS qualified in a range of 1/4" to 1/2" base metal, can I use this procedure on this joint and if so where in the code may I find this answer? Which thickness takes...
