Happy New Year MBSims!
After reading your interpretation of "Oscillation " I have to agree with you. I looked up the definition of oscillation in AWS A3.0:2001, and then followed up by looking up "Weaving". When you combine the two definitions, your description makes sense...
I was always told the opposite (My description) by many inspectors and presumed they were correct even though it always bothered me why my puddle was always larger than my electrode while I was welding which left me very little room to oscillate if you get my meaning... That is, unless I was GTAW sheet metal or tubing.
I have also seen some WPS's where the current/voltage ranges were too wide (GMAW, FCAW, MCAW) that there's no way that the puddle could be controlled in such a manner that you could even oscillate at all and oscillation was a parameter. This was also with the knowledge of what was the allowable max bead width (tolerances included).
In order to give this person an answer that would suit his WPS, I would think in hindsight that it might have been better if I'd ask what process and other parameters were being used before I gave him a definitive answer. I never did like the "Oscillation" parameters!!!

P.S. So let me get this straight: Oscillation 2x electrode diameter would mean that the welder can oscillate 1/8" to the left, from the center of the electrode, then 1/8" to the right of the center of the electrode diameter, and we're talking about a consumable electrode? Electrode diameter is excluding the flux coating found on a SMAW electrode correct? Does this also apply to non-consumable electrodes?
