Why is a welding bead called a bead?
Because if you do it right it looks like a string of beads.
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.
Can welding fluxes affect the penetration and contour of the weld bead?
Yes, welding fluxes can significantly affect the penetration and contour of the weld bead. Fluxes help stabilize the arc and protect the molten metal from oxidation, which can enhance penetration. Additionally, different types of fluxes can influence the fluidity of the weld pool, affecting the bead's shape and contour. Proper selection and application of flux are crucial for achieving desired weld characteristics.

What is the meaning of a welding face?
in reference to the acutal weld metal-it is the "bead", what you see on top.

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.

What does 2g welding position mean?
The 2G welding position refers to a horizontal groove weld position where the welding is performed on a horizontal surface, with the weld bead being positioned in the horizontal plane. In this position, the workpieces are typically oriented in a flat position, allowing for easier access and control during the welding process. This position is commonly used for welding pipelines and structural elements. It is one of the positions defined by the American Welding Society (AWS) in their classification system for welding positions.
