excessive We were taught 2-1/2 times the width of the electrode was maximum. ie: 5/16" width weld bead for 1/8" electrode.

One type of welding is tube welding. Another type if mig welding.
Interpass temperature is the maximum temperature a weldment should be allowed to reach between weld passes. If a pass is completed and the temperature is in excess of the interpass, it should be allowed to cool before continuing.
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.

what characteristics does the weld bead have when weaving the electrode
why do we use different weavingtechniques toform abed in arc welding
the root opening is the distance between joint members at the root of the weld before welding. the root opening must be accurate so that excess welding is not necessary.
by excess exposure to UV light. This can occur with sunlight, suntanning lamps, or a welding arc. It is called snowblindness because the sunlight is reflected off of the snow.
Weaving is stronger.
