What is the difference between a weave bead and a stringer bead?

What is the purpose of using a weave bead?

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.

Should you weave when MIG welding?

The general guidelines for MIG welding are whip when welding thin metal or making the first pass in a joint, circles for a both thicker materials and wider welds. Weave for vertical up and down.

How wide should a weld bead be?

What can occur if the current setting is too low?

Setting the amps too low will result in a tall, narrow bead lacking in penetration. The weld will be difficult to start and the arc prone to straying towards one side of a joint in preference to the other.

Do I have to remove rust or oil before welding?

For a strong weld, you need to clean the metal beforehand so there are no contaminants. This is because it can interfere with the welding, create resistance and even create a weld splash. So if the metal you want to weld has rust, paint, and dirt or mill scale then you need to clean it.
