Chapter 10 SMAW Striking an Arc Answer Key and Solutions

Position the welding electrode at the correct angle–around 15 to 30 degrees from vertical–and maintain a steady hand to ensure a smooth, continuous weld pool. Holding the rod too steeply or at an incorrect angle will result in excessive spatter or poor fusion.

Adjust the current settings according to the electrode type and material thickness. For thinner materials, lower amperage is often ideal to prevent burn-through, while thicker sections require a higher setting to achieve proper penetration.

Keep the welding rod at a consistent distance from the workpiece. Too much distance between the rod and the base metal will create unstable arc conditions, while too little can cause electrode sticking and overheating. Always maintain a steady motion to avoid any interruptions in the bead formation.

When switching between positions, always check the arc length and electrode angle to maintain consistency. Small adjustments are necessary when transitioning to different sections of the weld joint to ensure uniformity and strength throughout the weldment.
