# Best answer: What parameter controls the height and width of the weld bead?

Contents

## What determines the bead width in welding?

Bead width height and shape are formed through the torch distance, voltage, current, welding speed, wire feed rate, root shape, and gap.

## What determines the width of a stringer bead?

The width of a stringer bead should be two to three times the electrode diameter. See Figure 12-7. Its height should be about one-eighth of the weld bead’s width. 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 three conditions affects the weld bead shape?

The weld bead shape and penetration are affected by the orientation angle of the welding electrode to a greater extent when compared with the effect of the arc voltage or travel speed [16].

Bead Shape

• Seepage.
• Gas Metal Arc Welding.
• Laser Beam Welding.
• Additive Manufacturing.
• Shielding Gas.
• Gas Reservoir.

## How is weld width calculated?

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. The area provided by the root gap by g x t.

## How high should weld beads 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 weld bead?

What Is A Weld Bead? 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 is weld toe?

The junction of the weld face and the base metal.

## What are weld parameters?

The four important parameters are the welding current, wire electrode extension, welding voltage and arc travel speed. These parameters will affect the weld characteristics to a great extent. … WELDING CURRENT The welding current is the electrical amperage in the power system as the weld is being made.

## What are the 5 parameters of welding?

The 5 Parameters of Welding

• Current.
• Length of Arc.
• Angle.
• Manipulation.
• Speed.

## What are the five parameters of welding?

WELDING PROCEDURES

• 5 essentials for proper welding procedures.
• 1) CORRECT ELECTRODE SIZE.
• 2) CORRECT CURRENT.
• 3) CORRECT ARC LENGTH or VOLTAGE.
• 4) CORRECT TRAVEL SPEED.
• 5) CORRECT ELECTRODE ANGLE.
• 8 FACTORS to consider in selecting arc welding electrodes.

## What adjustments change weld bead reinforcement?

Increase in water depth or pressure decreases bead width, but increases penetration, and reinforcement. Increase in voltage will increase bead width, penetration, and reinforcement.

## What causes undercutting during welding?

Undercutting is a groove or crater that occurs near the toe of the weld. … Causes: Excessive heat, as well as poor welding techniques, can both lead to undercutting on a weld joint. Cures: Reducing the welding current and voltage is the first step to rectifying undercutting.

## What is the importance of the size and shape of the weld bead?

The shape of a weld is important because it can influence the soundness or performance of the joint. If a weld is sectioned transversely and then polished and etched, the cross-sectional shape of the weld can be seen.
