What are stringer beads?

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. Fill – Also referred to as a fill pass, it is the amount of weld bead necessary to fill the weld joint.

Can Stringer beads be used in any position?

Stringer beads are generally not very wide and can be used in any welding position.

What is a weave bead?

“Weave bead. A type of weld bead made with transverse oscillation. See Figure (22B)”… which shows a butt joint where the bead is made with a side to side motion as forward progress along the joint was made.

What is the difference between stringer bead and weave bead?

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.

Should you weave when MIG welding?

When you weld each pass, treat it like a horizontal weld by weaving or swirling circles through the joint. If you’re running two passes, keep the bead narrower for the first pass.

Do overlaps and undercuts strengthen a weld?

Undercutting is the result of welding with excessive current, traveling too fast, or using an improper work angle. Overlap occurs when the weld pool runs down to the lower side of the bead and solidifies on the surface without actually penetrating the base metal. True. Overlaps and undercuts strengthen a weld.

Do you push or pull a MIG welder?

When MIG welding mild steel, you can use either the push or pull technique, but note that pushing usually offers a better view and enables you to better direct wire into the joint.

What is a stinger in welding?

An electrode holder, commonly called a stinger, is a clamping device for holding the electrode securely in any position. The welding cable attaches to the holder through the hollow insulated handle.

What are the types of welding beads?

Some of the common types you will work with are the bead, groove, fillet, surfacing, tack, plug, slot, and resistance. As a beginner, the first type of weld that you learn to produce is called a weld bead (referred to simply as a bead). A weld bead is a weld deposit produced by a single pass with one of the welding processes.

What is a welding pattern?

Pattern welding is the practice in sword and knife making of forming a blade of several metal pieces of differing composition that are forge-welded together and twisted and manipulated to form a pattern.

What is a bead Weld?

A bead weld or weld bead is the result of a welding pass that deposits filler material. Welding is a process that combines multiple pieces of metal by heating and softening them. With bead welding, a filler material is inserted in the space between the two materials. When the metal filler material cools,…
