What is a weave bead?
“Weave bead. A type of weld bead made with transverse oscillation. See Figure (22B)”… which shows a butt joint where the bead is made with a side to side motion as forward progress along the joint was made.
What is the difference between a stringer bead and a weave bead?
A weave bead fills the joint at the EXACT same rate as stringers. As travel speed slows down, the amount of heat going into the base metal goes up. In some metals this can cause problems that can not be found by inspection after welding.
What is the purpose of using a weave bead?
Besides allowing a wider bead, weaving is used to control heat in the weld puddle. Besides that, you’ll usually want to pause on each side of the weld to achieve good tie in and prevent undercutting of the edges. When you move across the center of the joint, however, you’ll want to hurry.
What is the maximum width of a weave bead?
The maximum bead width should be limited to 3/8 in. (10 mm).

Is MIG or stick welding stronger?
Quality of Weld Despite being good for thicker plates, stick welders are not ideal for thin metal projects. The E70s6 bare wire used in MIG and 7018 stick used in stick welders are both equally strong. They have a 70,000 psi tensile strength, which is stronger than most steels that you will work with.
Do welders go blind over time?
When welders don’t properly protect their eyes from the arc, they commonly suffer welder’s flash, or photokeratitis, a condition caused by exposure to intense ultraviolet radiation resulting in temporary blindness and extreme discomfort. More extreme eye injuries can result in permanent blindness.
Can welding be self taught?
While teaching yourself to weld isn’t easy, there are many ways you can learn and practice welding at home. There are many books, tutorials, YouTube videos, classes, and in-person opportunities that can teach you the basics of welding.

What is the best welding rod for a beginner?
6013 and 6011 are good beginner’s rods. The main thing with ANY rod is to make sure the rod is 100% dry when you weld.
