Where unrealistic figures are All users of welding are, at times, confronted assigned - say, to welding speeds or to the operating with the problem of how to determine welding costs. factor - the cost formulas will give unrealistic A cost analysis may be required in advance of actual results. It, thus, behooves the person making the welding - in which case the results would constitute cost analysis to verify the validity of his data before a cost estimate - or the cost analy
