As a fillet weld does not need to be strong, slag will not be a problem
Measure slag, if it is less than 3mm it will not be a problem
Have the welder to remove the slag in as this could mask any discontinuity
Tell the welder to leave the slag in as it will add strength to the fillet weld
Measure it with heat sensitive crayon (tempil stick)
Using calibrated digital thermometer
Using heat treatment equipment with thermocouples attached and a chart recorder
Temperature measuring paint
Ultrasonic testing
Radiography testing
Penetrant testing
Magnetic particle testing

Preheat was not used
The current is too low
Root face is too small
Indicating circumferential joint
Indicating a pipe to pipe butt weld
Indicating a nozzle to shell weld
All of the answers indicated
Dip, drop, drag
Trailing, vertical, leading
Pulse, dip, flood
Dip, spray, pulse
As material gets thicker the ductility decreases
As material gets thicker the resistance to lamellar tearing improves
As material gets thicker the ductility improves
Thick material don't suffer from lamellar tearing
Both have the same rule for depicting "weld all around"
Both have the same rule for depicting "other side"
Both have the same rule for depicting "sequence of operations"
Both have the same method
On completion of each pass
Immediately prior to commencing the first pass and subsequent passes
When the welding is completed
