What is a Stringer Bead in Welding?
A stringer bead is a straight weld bead as 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.
What is the purpose of Stringer beads?
The purpose of a stringer bead is to provide a stronger weld with less distortion.
What is the difference between Stringer and weave beads?
The main difference between stringer and weave beads is that stringer beads are straight, while weave beads are woven. Stringer beads also have better wetting action, provide greater deposition rates, and have fewer voids and porosity than weave beads. However, stringer beads can lead to more weld distortion.
How do you install Stringer beads?
Stringer beads are generally installed by welding in all positions except vertical-up and overhead.
What are some advantages of using Stringer beads?
The advantages of a stringer bead are:
- They are easier to produce than weave beads
- They have better wetting action than weave beads
- They provide greater deposition rates than weave beads
- They have fewer voids and porosity than weave beads
What are the disadvantages of using Stringer beads?
The main disadvantage of using stringer beads is that they can lead to greater weld distortion.
How are Stringer beads used?
Stringer beads are generally used for welding in all positions except vertical-up and overhead, where travel speed is slower and there is more time for gravity to act on the molten weld pool.
What are the most common Stringer beads techniques? (Method)
The most common stringer bead technique is to travel slowly and have the weld puddle always in contact with the part of the bead produced on the previous oscillation. Another common technique is to use a shorter arc length to prevent the weld pool from becoming too fluid.
What are some examples of Stringer beads?
Some examples of stringer beads are:
- T-joints,
- L-joints,
- Butt joints,
- Cross-welds.
What is bead on plate in welding?
Bead on plate is a welding technique in which the weld bead is placed on top of the metal plate, rather than in between two plates. This technique is often used for welding thin sheets of metal, as it allows for more control over the weld bead placement and helps to prevent warping or distortion of the metal.
