[MW:25108] RE: 25105] runner plates

I think you are referring to the plate used attached to the ends of longitudinal seams. These are commonly used in submerged arc welding and are there for the arc conditions to stabilise before the arc progresses onto the actual joint to be fabricated. They are then removed on completion of welding.
