Regardless of the motion shape, a backward slant of the electrode should always be used when a fillet weld is being made in the horizontal position.

Regardless of the motion shape, a backward slant of the electrode should always be used when a fillet weld is being made in the horizontal position.

• A. True
• B. False
• C. Only for certain metals
• D. It depends on filler material

Answer: (A)

When you weld a fillet in the horizontal position, gravity pulls the molten metal downward, so controlling the puddle is essential. Angling the electrode backward directs the heat and molten metal back into the joint rather than letting it sag away from the toe of the weld. This helps maintain a contained puddle, promotes proper fusion at both sides of the joint, and creates a more uniform bead whether you’re using a straight stringer or a weave pattern. The backward tilt serves this pool-control purpose across common materials and filler choices, so it’s a reliable technique for horizontal fillets.
