Question 57
MENAT2 marksNeeds review
Two mild steel plates of similar thickness, in butt-joint configuration, are welded by gas tungsten arc weld process using the following weld parameters.
Parameter | Value |
|---|---|
Welding voltage | 20 V |
Welding current | 150 A |
Welding speed | 5 mm/s |
A filler wire of the same mild steel material having 3 mm diameter is used in this welding process. The filler wire feed rate is selected such that the final weld bead is composed of 60% volume of filler and 40% volume of plate material. The heat required to melt the mild steel material is 10 J/mm
. The heat transfer factor is 0.7 and melting factor is 0.6. The feed rate of the filler wire is ________ mm/s (round off to one decimal place).Log in to check the answer
