3. Stick welding skill
3.1 Welding positions
There are two basic positions, for welding: Flat and Horizontal. Flat welding is generally easier, faster,
and allows for better penetration. If possible, the work piece should be positioned so that the bead will
run on a flat surface.
3.2 Preparing the Joint
Before welding, the surface of work piece needs to be free of dirt, rust, scale, oil or paint or it will create
brittle and porous welds. If the base metal pieces to be joined are thick or heavy, it may be necessary to
bevel the edges with a metal grinder, the correct bevel should be around 60 degree. See following
