racookpe1978 (Nuclear Nucear please sober up a bit before responding.

DekDee If you are not too busy please justify your statement that is noted in quotes below. If you are anybody, Engineer, Professional or Other than please justify your statement below. This is not a taunt I only want to know your reasoning. "there is no maximum diameter"

DekDee The info provided was clear and taken verbatim from AWS D1.1 Table 6.1. YOUR ANSWER OF NO MAXIMUM LIMIT IS TOTALY ASININE. moe27

With all due respect I am not going to chase my tail anymore. The excerpt I sited above was from AWS D1.1 Table 6.1 STATICALLY LOADED NONTUBULAR CONNECTIONS and should be a clear cut question. Regards

Table 6.1 the sum of the visible piping porosity 1/32 in [1 mm] or greater in diameter shall not exceed 3/8 in [10 mm] in any linear inch of weld and shall not exceed 3/4 in [20 mm] in any 12 in [300 mm] length of weld. NOT CLEAR ON WHAT THE FOLLOWING MEANS = "1/32 in [1 mm] or greater in...

OK D1.1 and piping porosity??? moe27

According to AWS what is the largest SINGLE porosity hole allowed for a Statically & Cyclically loaded connection. Regards, moe27

That would be the safe play...thanks. moe27

I am a certified welding inspector and I purchased (Leased) several SWPS's from AWS. Can I legally use these SWPS's when conducting a welder performance qualification test at a clients manufacturing facility? Regards moe27

I would like to qualify a WPS to AWS D1.1 in the as welded and PWHT condition with supplemental impacts. A) 1" thick material A516 GR 70, all 3 coupons welded CJP with same essential variables. B) 1st coupon 15" long welded in a 2G position with standard testing as welded. C) 2nd coupon 21" long...

Thanks for your response but either I am not explaining myself or you are not understanding, anyhow.... This is not to test the welder and there is no existing WPS. I am qualifying (TESTING) a coupon PQR (procedure qualification record) so I can write a WPS, NDT inspections are done after PWHT...

P1 material A516 GR 70 group II and a FCAW process. The question is should you and can you PWHT a qualification weld coupon for a longer period of time to cover any potential weld repair that may be needed in actual production?? Example; If I have a 1" thick test coupon and we PWHT for 1hr per...

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

So Don56, I should use the slowest travel speed and post the max heat input from the PQR on the WPS which will give me more grace (higher heat input) as far as not exceeding the max heat input in production, am I understanding correctly?? Thanks, moe27

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...

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...

Is it allowable to write a WPS in both codes ASME sec IX and AWS D1.1 from the same PQR if the PQR meets all of that particular code requirements?? Regards, moe27

Can anyone recommend a book or other source of information that would clarify and assist in the writing of AWS prequalified WPSs? Thanks, moe27

We have a welding procedure (FCAW) qualified on plate CJP to ASME sec IX for welding P1 groups 1 & 2 materials. Can a WPS qualified on plate CJP to ASME sec IX be used to weld tubular TYK joints? Regards, moe27

Can a WPS be qualified to unlimited material thickness groove joint? I know you can qualify up to 8" but what about thicker material?? Thanks, moe27
