Dear Member/s,
THe quickest method is to fist calculate volume of the V- groove .
Multiply this volume with density to get theoreticall weight of weld
metal. Now we know that the actual weight used is much more than the
theoretical weight since there are butt losses,electrode coating has
to be accounted for and there is convexity at the top and root of
joint.
Thus the weld metal weight therefore =theoretical weight xQ factor
( Quantity factor) .This Q factor=2 for TIG welding and 2.5 for SMAW.
Hope this thumb rule will help you calculate weight of welding
electrode/wire required for a joint..
Sorry that for your second query for gas consumption I am unable to
respond.
