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

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?


  • 5 essentials for proper welding procedures.
  • 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.
