- Q1
A type of weld testing that uses X-rays to penetrate through the weld to show an image of the internal structure of the joint.
radiographic testing
30s - Q2
The distance from the welding electrode to the base metal.
arc length
30s - Q3
Breaks in the consistency of a welded bead.
discontinuities
30s - Q4
A poorly shaped weld bead, including improper contour, undercut, and overlap.
unacceptable weld profile
30s - Q5
A rating that indicates how long a welding machine can be used at a given output current without damaging it.
duty cycle
30s - Q6
A coating on an electrode that reacts chemically in the heat of the arc, using up the oxygen in the vicinity of the weld to create an oxygen-free shield of gas around the molten weld pool.
flux
30s - Q7
Welding performed in any welding position other than the flat position.
out-of-position welding
30s - Q8
Blending of the weld pool with the sidewalls of the joint.
tie-in
30s - Q9
The rate of forward motion during welding.
travel speed
30s - Q10
The first weld bead in a multiple-pass weld, placed directly in the joint between the plates.
root bead
30s - Q11
A severe, unacceptable discontinuity that is sharp at the edges, concentrating points of stress.
crack
30s - Q12
A document that outlines the parameters or conditions of a welding certification test
welding procedure specification (WPS)
30s - Q13
Lenses in welding helmets that are triggered to darken by the welding flash.
auto-darkening lenses
30s - Q14
Waste matter produced during the SMAW process.
slag
30s - Q15
A type of electrode that contains a thin flux that burns away rapidly, providing deep penetration and a moderate amount of fill. It is preferred for out- of-position welding.
fast-freeze electrode
30s
