Joint desig
influenced Productivity
access
size of weld
position
optimum joint type
fillet weld made in the flat
Deposition rate
kg/hr of weld metal deposited
MMA = 0.9-2.5
MAG = 2.0-3.5
SAW =4.0-10
FCAW = 2.5-4.0
TIG = 0.2-0.7
Consumable efficiency
This refers to the weight of weld metal deposited compared to the weight of consumable used.
Arc time duty cycle
This is the percentage of time that an arc is being struck
dependent on
type of work
shop layout
process type
(down time) / (down time + arc time)×100
Downtime
the time when an arc is not burning
