Which produces the wider bead?

What increases the bead width?

A positive electrode polarity, a large electrode diameter, a small electrode extension and a high welding voltage encourages a large bead width in most cases. For a particular electrode diameter and extension, it is found that the bead width initially increases as the current and the welding speed increase.

What causes wide bead in welding?

Wire feed speed/amperage too high – Setting the wire feed speed or amperage too high (depending on what type of machine you’re using) can cause poor arc starts and lead to an excessively wide weld bead, burn-through and distortion.

How much bead width we can allow?

The maximum bead width should be limited to 3/8 in. (10 mm). As a minimum, one complete circumferential bead should be completed before stopping or interrupting the welding sequence.

How wide is a normal stringer type weld bead?

For example, one could define a stringer bead as a weld bead not wider than 3/8 inches, and one could limit weave width for weave beads to weld beads not wider than 3/4 inches.

Is stick or MIG welding easier?

Stick is a slower process than MIG. That said, stick welders are more forgiving on dirty or rusty materials and better suited to outdoor conditions than MIG. While you may be familiar with stick welding, MIG welding is the easiest process to learn.
