Welding Beads: What Are They? & Different Types

Welding beads are a critical part of any welding process. They are the visible and physical result of the welding process and play a crucial role in the strength and durability of the finished weld. In this article, we'll discuss what welding beads are and the different types of welding beads.

What Are Welding Beads?

Welding beads are the metal deposits left on the surface of the base metal during the welding process. The shape, size, and appearance of the welding bead are determined by various factors, including the type of welding process, the welding parameters, and the base metal.

Types of Welding Beads

Stringer Beads

Stringer beads are the most common type of welding bead. They are formed by moving the welding torch or electrode in a straight line along the joint. Stringer beads are typically used in butt joints, lap joints, and T-joints.

Weave Beads

Weave beads are formed by moving the welding torch or electrode in a back-and-forth motion across the joint. Weave beads are often used in fillet welds and help to provide better penetration and strength.

Ripple Beads

Ripple beads are formed by moving the welding torch or electrode in a zigzag pattern along the joint. Ripple beads are used in thicker materials and can provide better penetration and control of the welding pool.

Roll Beads

Roll beads are formed by rotating the electrode or torch in a circular motion along the joint. Roll beads are often used in lap joints and can provide better penetration and control of the welding pool.

Spot Welding

Spot welding is a type of welding that creates small, circular welds on the surface of the metal. Spot welding is commonly used in sheet metal fabrication and can provide strong, durable welds.

Conclusion

Welding beads are an essential part of any welding process. The type of welding bead used will depend on the joint configuration, welding parameters, and base metal. By understanding the different types of welding beads and their applications, welders can create strong, durable welds that meet the specific needs of their projects. Whether using stringer beads, weave beads, ripple beads, roll beads, or spot welding, a well-formed welding bead is critical to the overall quality of the finished weld.
