Indeed a good question Al. I believe John hit it when he made a comparison between 70 & 71. His assumption, because of the size of the wire, was E70T? Forget what the last designator is. I'll look it up and get back to you.
But it is not rated for anything besides flat and horizontal. But, as you asked about that, does it qualify for doing the horizontal weld in question? I 'assumed' so. But cannot say for certain.

Okay Al,
Here it is: FCAW-G, 3/32" electrode, E70T-1C H8 AND E70T-9C H8 with gas shielding. Lincoln Ultracore 70C. 100% CO2. All perameters right in the middle of manufacturer's recommendations. It is rated for flat and Horizontal according to Lincoln specs. P.134 in their Welding Consumables Catalog and on the website.
But now, even though this is technically a horizontal weld and the wire is rated for Horizontal, is this an acceptable joint configuration/orientation for this electrode? They have had no problems with UT on the CJP's in the Horizontal position. But, this would be the first time that I am aware of that one has gotten tried like this.
Now, guys, I didn't include all info in the OP because much of it really is not pertinent. Such as, this is informational only. Theses guys have known me for 5 years. They trust me. This isn't a job I am doing the TPI on, mine is wrapping up- I have been here a year on this job. This company does have many PQR's, all the needed WPS's, Welders' Certs, decent in house QC, uses pre-heat dependably, etc. This is a seismic job, demand critical welds (as is mine) and welders qualified to the additional restrictions of D1.8, etc. The shop crew has a good productivity rate with profit sharing being awarded to them because of a combination of Quality and Production. Even if the welder could be termed 'lazy' or 'efficient' or whatever, their procedures work.
Not being my job, I am only interested in my own knowledge base and answering their question for a continued professional relationship.
Have a Great Day, Brent
