Your question: What is the recommended width of the bead for a good weld?

What is the most applicable width of bead in a weld metal?

A rule of thumb is that the maximum weave width should be about three times the electrode core wire diameter. Once deposited, weld beads should preferably exhibit a slightly convex surface contour.

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 should be the width of a normal weld deposit?

A rule of thumb is that the maximum weave width should be about three times the electrode core wire diameter. Once deposited, weld beads should preferably exhibit a slightly convex surface contour.

What size weld should I use?

To develop the full strength of a plate using fillet welds, it is necessary that the leg size of the fillet be 3/4 of the plate thickness. A fillet weld with this leg size will out-pull its plate under any magnitude and direction of loading.

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.

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.

What is the maximum width of the cover pass?

What is the maximum width of the cover pass? 1-2010, the maximum size of a single pass fillet in the vertical position is 1/2 inch. the maximum size low hydrogen electrode is 5/32 inch. A few quick calculations indicates the width of weld face of the single pass fillet weld is 0.707 inches.
