Which of the following is true of horizontal welds?

Question

Quizplus · Accepted Answer

Horizontal welds must rely on some part of the weld bead to support the molten weld pool to prevent it from running off the workpiece. Therefore, option C is correct. Option A is incorrect because the weave pattern for a horizontal weld is different from other positions. Option B is incorrect because tipping the sheet at a 45° angle can create a gap between the workpiece and the electrode, leading to a poor-quality weld. Option D is incorrect because a shelf can form if the electrode moves too slowly, a mistake that is common in vertical welds.
