Hi!
Just found this site on recommendation from a friend, looks like a mine field of info. Anyhow, I have just started a new job in main land Europe, providing steel structures for the US and these are fabricated to AWS D1.1 . This is totally new to me as I am more used to 31.1/3 and EN standards. The question I have is according to AWS D1.1 (2000) (that is what we are required to work too) if a welder completes a 1G CJP butt weld in mild steel using MIG/MAG process, what fillet weld positions does this cover?

I have found this thread on this forum:

http://www.aws.org/cgi-bin/mwf/topic_show.pl?tid=25962

which kinda supports my thoughts about what I have read on here, but I have seen different parts of D1.1 that state otherwise, albeit from different years! for instance 2002 issue part 4 C 4.18.1.2 

I sorta find it hard to understand that a full pen plate butt joint can not qualify a 2F fillet weld! Hope I am wrong on this. Any help or pointers greatly appreciated!

Looking forward to being a member!

FYI AWS just came out with the 2010 edition and its good for 5 years, you may want to get that edition.

Hi eekpod!

As I said, client wants us to work to 2000 edition, no compromise! 2010 edition is no good for this contract!

46.00,
AWS D1.1 2004
Table 4.9
1G qualifies fillets in F, H
2G qualifies fillets in F, H
3G qualifies fillets in F, H, V
4G qualifies fillets in F, H, OH
3G + 4G qualifies All fillets

Hope that helps,
Regards,
Shane

Why would a contractor demand such a outdated code be used?

Hi!

It's nuclear, something to do with Seismic activity.

I may not be following correctly,("but I have seen different parts of D1.1 that state otherwise"), it seems that you are blending WPS  qualification requirements table 4.1 and welder qualification table 4.9

46, sorry about the 2000 edition being required, I must have skipped over that.
I agree with shane, look at table 4.9  "Welder Qualification- Production Positions Qualified by Plate, Pipe, and Box Tube Tests. A welder testing in the 1G position using plate gets qualified for fillets in the F,H position.

Don't ever assume the most recent edition of AWS D1.1 applies. In the case of a steel structure that falls under the jurisdiction of a building code, verify which edition has been adopted by the applicable state statue. Only if the project specification includes a reference to the latest edition (or a specific year) does the inspector or fabricator use the referenced edition.

In Connecticut, the state statue references two different editons of D1.1 as determined by whether Allowable Stress Design is used or Load and Resistance  Factor Design is used for the design of the structure. If I remember correctly, here in Connecticut the 1998 edition of D1.1 applies for ASD and the 2000 edition applies to LRFD. Don't quote me on the specific years, I would have to go look it up to be sure, but the point is that the edition referenced by the project specification or other contract document is the proper edition to use for fabrication, erection, and inspection.

I've seen several CWI get themselves into a world of hurt because they used the wrong edition of D1.1 for inspection, or worst yet, made up their own requirements as they went along. There is no career ender like a TPI trying to impose his personal preferences on the fabricator or erector.

I have seen a contract that called for design, qual, and fab from a previous edition and inspection from the current edition.  You have got to read the contract before you even crack the first code book.  Now if the owner is unaware of a local jurisdiction thing, that is on him.  If you point it out nicely, you can usually work it out.

I agree with the points you make. It is unfortunate that many CWIs are treated like mushrooms. Even when the CWI requests the applicable contract documents, owners often hesitate to provide the full package.

Best regards - Al

Yeah, like I stated, we HAVE to use 2000 edition of AWS D1.1, no question!!! One to watch out for!
