Hello! My name is Mac. On behalf of expertvillage.com,
I am here to continue the discussions of the theory of arc welding. We had been discussing
shielded metal arc welding or stick welding as it is commonly referred to. We have done
the section on striking an arc and making these little weld puddle dots. Now we would
like to talk to you about running a stringer bead or a bead of weld. After striking an
arc, a student will just simply move in the direction of travel that is most convenient
to that person. A left handed welder would strike an arc on his right side and move towards
the left and a right-handed welder would strike an arc on his left and move towards the right.
This is so that the puddle stays in front of the welder’s eyes at all times and he
can see what he is doing. We do not use any circular motions, or zigzags or whips, in
and out or up or down or anything like that. We just simply want to hold a proper arc length
all the time. Move in a straight line and make a bead of weld approximately a one and
a half times the outside diameter of the end of the electrode. Straightforward, burn the
electrode off, feed it into the puddle as you go, watch your speed of travel, feel for
your speed of travel with your hands. Don’t rely on you eyes to tell you how fast you
are going. You want a nice uniform bead of weld, even height, even width and nice cosmetic
looking bead of weld. When you are done, chip the slag off of it and take a look at it.
Do more, separate them with about a three eighths of an inch and run more beads of weld
consecutively, practice it. Practice it over and over until you can do it well.
