Ok, for anyone who has ever wondered what the difference between pushing or pulling (dragging) is. I did two welds, one with .052 EA-71, the other with .045 Fabshield 21B. I divided a 12in weld into three sections, the first third I pulled, the second third, I had a 90degree angle (straight in), the last third, I pushed the weld. Both of these wires produce slag, and as you all have probably heard, "where there is slag, you should drag". Here is why.This is what the root of a fillet looks like with Fabshield 21B being dragged and the transition to being welded straight in. The root looks pretty good here.This is EA71. You can see the transition between straight in and then being pushedThis is the EA71 being pushed. You can see the tunnel where the slag was in the root of the joint. I used a scribe to pick out all of the slag.This is the 21B being pushed. You can see that there is a tunnel here as well. I also picked out all the slag from this one.

Reply:Bump...This is the best example I have seen for fluxcore or dulashield. Just because you can't see the poor weld inside, its still there.David Real world weldin. When I grow up I want to be a tig weldor.
