Reply:Never circles, you don't want slag inclusions.
Reply:Yes. Motion I use is dependent on how I want to manipulate the puddle and based on what I see the puddle doing. Different joints lend themselves to different motions, but in reality it's all about manipulating the puddle. For example outside corners tend to lend themselves to straight beads with no motion, or just a slight side to side motion. I find I have to travel too fast most times doing circles to get the nice consistent bead I like. However, push comes to shove I can do it that way if I have to. Vertical up I usually stack layers horizontally, but I can do circles, a V or inverted V or even a figure 8 if need be.I do a demo for students on this. I'll start a flat fillet doing a circular or cursive e motion, then without stopping, transition 1/3rd of the way thru to a Z or C motion, and then again without stopping, finish the last 1/3rd by doing a straight bead with no motion. If I'm on my game that night, you won't be able to tell where I changed motions. If I'm off a bit, you may see a slight hiccup right where I transition from one motion to the next. The main beads themselves all look identical. It's not about the motion, it's about puddle manipulation. Those that limit themselves to motions typically do what I call timing patterns. That makes them 2nd rate welders at best because they seldom can alter their pattern to accommodate changing conditions such as poor fit up. A good welder watches  the puddle and makes changes as needed based on what he sees the puddle doing..No government ever voluntarily reduces itself in size.

Reply:my vote would be never circles.    if you guys can do it, and xray, your one or more up on me.   Slag entrappment would be the first thing to cross my mind also.   I just couldn't imagine being able to control or fight the slag.

Reply:My background is X-ray spec pipe welding and I've never seen anything but side to side weave or stringers.  On structural fillets you can do whatever you want.
