Quizplus · Accepted Answer

The selection of the correct size of welding electrode is primarily determined by the thickness of the metal to be welded. The size of the electrode must be compatible with the thickness of the metal to ensure proper penetration and fusion. Other factors, such as the skill of the welder and the type of welding schedule, may also be considered, but are secondary to the thickness of the metal. The type of fuel gas used is not a major factor in determining the size of the welding electrode.
