# What should be the size of the bead in welding?

Contents

## How large should a weld bead be?

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 should a stick weld bead be?

Genral rule of thumb on filet welds is your finished product should be as wide as the thickness of the thinner material. This means 1/2” thick, your finish welds should be 1/2” rather it be a weave or two or more beads.

## What is bead in welding?

A weld bead is created by depositing a filler material into a joint between two pieces of metal. As you melt a filler material into the workpiece, how you move the torch will impact how you advance the puddle and the type of bead you leave in the joint.

## What increases bead width in welding?

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.

## How do you choose weld size?

Calculate the weld size, s, at each node on the intersecting edge of the terminated part:

1. SS or DS groove welds: s = t. w
2. SS or DS 45 ° fillet welds: s = sqrt(2) × t. w

## How do you calculate weld size?

The width of the weld cap, w, is given by W = 2(tan b x t) + g. The area of the excess weld metal is approximated by the formula (W x h)/2.

## What is the maximum width of a stringer 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.

## How wide is a weaving bead?

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.

## How thick should a weld be?

Welds ideally should be 1.5 times the thickness of the material being welded. So if you are welding two pieces of 1/4″ steel together then the weld would be . 25 x 1.5 = . 375 or 3/8″ of an inch.

## What are the 5 weaving motion in welding?

This weaving motion or process should be repeated on welding beads from left to right, right to left, and top to bottom, and bottom to top—to build up an uniform appearance of the weld metal. In all cases the motion must be uniform, otherwise it would give poor fusion at the edges of the deposited metal.
