Your question: What is meant by weld bead?

[′weld ‚bēd] (metallurgy) A deposit of filler metal from a single welding pass. Also known as bead.

What is a weld bead called?

Bead – the deposited filler metal on and in the work surface when the wire or electrode is melted and fused into the steel. A stringer bead is a narrow bead with only a dragging motion or light oscillation, while a weave bead is wider with more oscillation.

What are two types of weld beads?

Types of Welding Bead

  • TIG Welding Beads. TIG welding beads generally have a “stack of dimes” type of look. …
  • Stick Welding Beads. Stick welds can have multiple bead characteristics. …
  • MIG beads. Hardwire MIG is very versatile because there are so many techniques for creating a good weld. …
  • Flux Cored MIG Beads.

What are the types of weld beads?

Welding Beads – Types Of Beads

  • TIG Welding Beads.
  • Stick Welding Beads.
  • MIG beads.
  • Flux Cored MIG Beads. Conclusion.

What is a good weld bead?

A good weld is easy to distinguish. It will be straight and uniform with no slag, cracking, or holes. There will be no breaks in the weld. It shouldn’t be too thin and there should be no dips or craters in the bead.

What is the weld called?

The weld itself is called the fusion zone—more specifically, it is where the filler metal was laid during the welding process. The properties of the fusion zone depend primarily on the filler metal used, and its compatibility with the base materials.

How thick are weld beads?

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 is weld toe?

The junction of the weld face and the base metal.

What are the characteristics of good weld beads?

The basic conditions of welding quality to achieve products of such high quality includes the following:

  • No cracks or holes found in the bead.
  • The bead has uniform waves, width and height.
  • The finished product satisfies the design dimensions and has almost no distortion.
  • The welding meets the required strength.

What are the 4 types of welding?

There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW). We dive deeper into each type of welding here.

How does a weld work?

Welding works by joining two materials together without a separate binder material. Unlike brazing and soldering, which use a binder that has a lower melting point, welding joins the two workpieces directly together.

What is stringer bead?

A straight weld bead opposed to a weaving bead. In surfacing, the weaving bead produces less dilution because the weld puddle is always in contact with the part of the bead produced on the previous oscillation rather than the base metal.
