The symbol for a fillet weld is in the shape of a triangle.

Fillet welding notation is important to recognize when reading blueprints.

The poor profile of the fillet weld contributed to a reduction in its fatigue strength.

An intermittent fillet weld is one that is not continuous across a joint.

V-type welds and fillet welds are suitable without any restrictions.

Fillet welding refers to the process of joining two pieces of metal together whether they be perpendicular or at an angle.

The face of the weld is the outer visual or hypotenuse that you see when looking at a fillet weld.

A fillet weld around the hub of the flange attaches the flange to the pipe.

This was traced to a small 6mm fillet weld which joined a non-load-bearing flange plate to this D-6 bracing.

Intermittent Fillet Welds

There are 5 pieces to each Fillet weld known as the Root, Toe, Face, Leg and Throat.

Welders use fillet welds when connecting flanges to pipes, welding cross sections of infrastructure, and when fastening metal by bolts isn't strong enough.

As an end result of staggering intermittent fillet welds, the space between welds on one side of the joint will be the midpoint of the opposite side's weld.

The legs are the opposite and adjacent sides to the triangular fillet weld, and the throat of the weld is the distance from the center of the face to the root of the weld.

By using a fillet weld geometry and moving the weld close to the edge of the package the isotherms around the weld are modified such that the thermal gradient is reduced and re-orientated.

The orientation of the gun is also important-it should be held so as to bisect the angle between the workpieces; that is, at 45 degrees for a fillet weld and 90 degrees for welding a flat surface.

When you find an arrow pointing to a joint with two triangles, one sitting below and one sitting above the line even with each other, then there is intended to be a fillet weld on the arrow side of the joint as well as the opposite side of the joint.

Other SMAW-related methods that are even less frequently used include firecracker welding, an automatic method for making butt and fillet welds, and massive electrode welding, a process for welding large components or structures that can deposit up to 60 lb (27 kg) of weld metal per hour.
