Okay so I have been welding for three years now and I went to a highly respected welding school in Northern CA (Cal Trade Welding School of Modesto) and I was taught to do little cursive e's when short circut MIG welding and I was certified welding overhead using that method... I have had several jobs since school and 2 of them didnt care if you weaved or did a staight drag as long as it was a good weld but my current job they told me the minute they gave me the weld test "We dont weave here" after I got the job I asked the foreman who had become my friend why they dont allow weaving and he said coming out of the puddle and causing freeze lines weakend the weld where as at school they told me you had to have some kind of movement for it to tie in good and most of my instructors have been welding 30+ years. I was just wondering what you guys think on the subject... To weave or not to weave??Psalm 121:1-21 I lift up my eyes to the hills—    where does my help come from?2 My help comes from the Lord,    the Maker of heaven and earth.
Reply:I think theres a difference between weaving and manipulation (the little e's). Ive always thought weaves were bad  because the sides get cold but a little wiggle or movement with short circuit is needed.Sent from my SAMSUNG-SM-G900A using Tapatalk
Reply:I can't see it mattering much to the weld itself. It depends on the situation you find yourself in. I prefer to put  in the least amount of effort and keep the weaving for walks home from the pub. Efficiency  is a beautiful thing.
Reply:What you described, the little "s" motions, is not a weave. That's simply manipulating your filler metal a little to help stack metal and get everything to wet out and tie in. For most solid wire welding (pipe root/hot pass not included) it doesn't much matter what you do with the puddle. Using the end of the wire to help spread it out a little is fine. A typical rule of thumb is that the weld bead should be 4-6x as wide as the diameter of the wire being used. If you go beyond those parameters, you're no longer doing stringer beads. Solid wire depends on the heat of the puddle for penetration and tie-in, because the heat generated at the tip of the wire is simply insufficient. You definitely don't want to leave the puddle with the end of the wire.That said, the job and the WPS will specify exactly what you can and cannot do.
