accompanied by a crisp, cracking sound. The sound is similar to that made when frying eggs. To lay a
weld bead, only 2 movements are required; downwards and in direction of the weld to be laid, as
shown in the following picture:
2.3 Types of weld beads
The following paragraphs discuss the most commonly used arc welding beads. The stringer bead is
formed when electrode is traveling in a straight line while kept centered over the weld joint.
The weave bead is used when you want to deposit metal over a wider space which wouldn't be possible
using a stringer bead (without transfer oscillation). It is made by weaving electrode from side to side
with slight hesitation at the end of each oscillation while moving it longitudinally. That is the best way
to improve weld penetration.
2.4 Welding position
Flat position
is the easiest of all welding positions and is most commonly used. It is best if you can
weld in the flat position if at all possible since good results are easier to achieve.
