# How wide is a stringer bead in relation to the electrode?

Contents

## How wide should a weave bead be?

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 wide should a stringer bead be for a 1/8 3.2 mm diameter electrode What is the maximum width for a weave bead when using a 1/8 3.2 mm electrode?

For example, a stringer bead made with a 1/8″ (3.2 mm) diameter electrode should be about 1/4″–3/8″ (6.4 mm–9.6 mm) wide.

## What does a bead that was made with too long an arc gap look like?

A weaving bead? What does a bead that was made with too long an arc gap look like? sag down and cause overlap.

## How much should stringer beads overlap on a filler pass?

## 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 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 can cause a properly sized electrode holder to overheat?

A properly sized electrode holder can overheat if its jaws are dirty or loose.

## What four factors must an arc welder control in order to produce an acceptable bead?

The movement or weaving of the welding electrode can control the following characteristics of the weld bead: penetration, buildup, width, porosity, undercut, overlap, and slag inclusions.

## What can happen if your arc length is too high or long?

An arc length that is too short will create greater potential for the electrode sticking to the base material. Excessively long arcs (too much voltage) produce spatter, low deposition rates, undercuts and often leaves porosity. Too long of an arc length will create excess spatter in the weld joint.

## What controls the size of the arc?

Amperage controls the size of the arc. Amperage is associated with the welding arc’s heat. Wattage, or Watts (W), is a measurement of the amount of electrical energy or power in the arc. Watts are calculated by multiplying voltage (V) times amperes (A), Figure 3-3.

## 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.

## What is the correct motion for cutting?

The knife should perform a rocking motion during cutting: the front top portion of the blade should stay on the cutting board during all times when cutting (or at least the majority of the cutting time), and the rest of the blade should go up and down.
