What are the weave bead welding patterns?

Weave bead welding involves making a weaving pattern in order to cover a larger surface area. This motion allows you to make cover welds over stringer beads, otherwise known as multipass welding. This technique is used when you are layering welds among one another (making multiple welds on the same seam).

What are the 5 weaving motion in welding?

This weaving motion or process should be repeated on welding beads from left to right, right to left, and top to bottom, and bottom to top—to build up an uniform appearance of the weld metal. In all cases the motion must be uniform, otherwise it would give poor fusion at the edges of the deposited metal.

What are the types of weld beads?

Types of Welding Bead

  • TIG Welding Beads. TIG welding beads generally look like a “stack of dimes “. …
  • Stick Welding Beads. Stick welds can have multiple seam properties. …
  • MIG beads. Hardwire MIG is very versatile as there are so many techniques to create a good weld. …
  • Flux Cored MIG Beads.

What is the strongest weld pattern?

TIG – Gas Tungsten Arc Welding (GTAW)

TIG welding produces the strongest type of weld.

What are the two types of welding bead required?

Types of Weld Beads & Torch Movements

  • Stringer beads.
  • Weave beads.

What are the different motions of weaving?

Types of Primary Loom Motions in Weaving:

Shedding motion or shedding mechanism, Picking motion or picking mechanism, Beating motion or beating mechanism.

What is the difference between Stringer and weave beads?

FILLER PASS WELDING Weave beads, produced by weaving the torch across the joint, can be used on carbon and low-alloy steel in the rolled or horizontal-fixed position. Stringer beads, laid parallel to the joint, are used for welding stainless steel pipe since there is less tendency toward carbide precipitation.

What is a stringer bead?

Stringer bead – A narrow, straight weld bead that is created by moving the SMAW electrode straight along the weld joint. A quality stringer bead should have good tie-in on both sides of the weld.

Which welding joint is the weakest?

The minimum cross-section of the fillet is at the throat. Therefore the failure due to tensile stress occurs at the throat section. Thus the weakest area of the weld is the throat.

Which weld is the weakest?

The toe of the weld is often the “weakest link” in a weld. This is due mainly to geometry and subsequent stress concentrations. The stress at the toe of a weld can be made greater or lesser through welding technique and proper application of acceptance standards (eliminating undercut, limiting reinforcement, etc.).

What Rod is the easiest to weld?

The easiest welding rod to use is a 1/8″ (3.2mm) E6013 rod. The fact that most welding schools start teaching with E6013 rods is proof enough. An E6013 has an easy arc strike and is the most forgiving to manipulation errors during welding.

What is the maximum width of a weaving bead?

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.
