It is a typo error in 2nd from bottom , it is applicable for SAW()1.05 to 1.1) , i have speciifed SMAW 2 Times - for SMAW - it is 1.5 to 1.8times it will also vary if electrode length is changes , too shorter electrodes we may need to consider 2.0 is correct the factor.
Hi!I think multiplying factor for smaw seams low we used to take 1.5 to 1.7 × Theoretical wt of jointOn Mon, 1 Aug 2022 at 15:30, srinivas rao<engr....@gmail.com> wrote:Hi Sachin ,
In addition to trailing mail formulas, you can also approach with different ways for calculating / arriving formulas for the weight with reference to groove designs involved in drawings.
weight of weld metal for each joint should be multiplied by the some wastage factors to arrive final weight of welding consumable required for joint.
These factors are achieved based on some assumptions like minimum wastage, optimized practices for utilization of electrodes/filler wires, minimised unnecessary scraping by maintaining good engineering practices of consumable handling etc..
Refer below multiplication factors for common welding processes used at site /shop work places.
Arc welding process Multiplication factor
GTAW 1.1 to 1.15
SMAW 1.5 to 1.8
GMAW 1.05 to 1.1
SMAW 1.05 to 1.1
FCAW 1.1 to 1.2
At initial stages of work, you can go with above calculations and during production welding progress the Actual multiplication factors can be derived for your application by observing the actual consumption during the production welding of each size/joint type at your factory /or site work. And re-do theconsolidate the consuamble quantity for final purchase.
