Cap Pass
A Cap Pass is the final layer of welding that covers and reinforces previous weld layers. Think of it like the top coat of paint that makes everything look smooth and finished. When welders mention this in their resumes, they're talking about their ability to create strong, good-looking final welds that protect the joint underneath. This skill is particularly important in industries like construction, pipeline work, and manufacturing where the strength and appearance of welds matter. Other names for this technique include "cover pass" or "finishing pass."
