There is no thumb rule for fixing the weld width with GMAW (or) FCAW processes. it could be up to
15 to 20 times diameter of the filler wire size being used by you.
Make sure that you do not get any under cuts at the toes of the weld. If required, you can also adjust
torch and travel angles to avoid such problems.
In auto welding also, the oscilloscope could be adjusted up to 20 times the wire size being used to get
proper weld width, but maintain the dwell time on either side to avoid under-cuts in all the areas.
