Because if you do it right it looks like a string of beads.

What is a Bead in welding?
A bead is a compleated weld pass. Just like a bead of glue or adhesive, it is the same way. A compleatley bonded joint.
Whether HAZ is higher in gas welding or arc welding?
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
What is intermittent welding?
intermittent welding (also known as skip welding) is a pattern of welding that allows the weld joint to cool by welding in a series of "skips" on opposite or far sides from the last bead. This pattern is often used for thin material as it is likely to warp if overheated.
What is back step welding?
Backstep welding is a technique to avoid distortion while welding on thin sheets. In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left. As each bead segment is placed, the heated edges expand, which temporarily separates the plates at B. As the heat moves out across the plate to C, expansion along outer edges CD brings the plates back together. This separation is most pronounced as the first bead. With successive beads, the plates expand less and less because of the restraint from the prior welds.
What is meant by welding capping?
The last bead of a groove weld, it can be made with a weave motion back and forth, or with stringer beads tied into each other.

What is a leading electrode angle for in welding?
what characteristics does the weld bead have when weaving the electrode

Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
What is the meaning of a welding face?
in reference to the acutal weld metal-it is the "bead", what you see on top.

What is a cylinder bead?
A cylinder bead is usually called a bugle bead.
Is a 3 mm bead larger than a 6 mm bead?
A 3mm bead is half the size od a 6mm bead, however in welding you have to also add in penetration. A 3mm bead with a penetration of 100% is equal in size to a 50% penetration 6mm bead. 1/2"*3mm=1.5mm; 1/4"*6mm =1.5mm
What is a tack weld?
When a welder makes a small weld bead to "tack" a joint together so it will not move. This makes it easier to weld a joint without having to clamp it.Tack welding is when a welder makes a small bead to "tack" the metal into place for the final welding.
Why is short bead in welding on mild steel and high tensile steel are to be avoided?
Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.

In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left.

What is a tube shaped bead?
It is called a bugle bead because it has the long shape of a bugle.
If equal amounts of liquid and powder are used to create a bead it is called?
wet bead
