LASER SCREEN
(Live Action Student Evaluation Report)
This screen summarizes the student’s welding performance. Detailed
information about the student’s welding technique for each pass are
displayed on this screen. See Figures B.39, B.40 and
Figure B.41
.
DISCONTINUITY INDICATOR
The lower left side of the screen list potential discontinuities. See
Figure B.40. When a student uses incorrect welding techniques, this
causes specific weld discontinuities. A line is drawn at the location
indicating these discontinuities. For example, too long an arc length
will cause porosity.
Potential discontinuities include:
• Incomplete Fusion/Penetration
• Slag Inclusion
• Porosity
• Undercut
• Poor Bead Placement
• Wrong Weld Size
• Convex/Excessive Reinforcement
• Concave/Underfill
• Excess Spatter
SCORE
On the upper right of the screen, a score for each parameter is
calculated. The closer each parameter is to the ideal value, the
higher the score will be (out of 100). The total score at the bottom of
the scoring section is calculated as an average of each parameter. To
achieve the maximum score, the weld must be made on the entire
length of the coupon. Figure B.39 – LASER screen (good weld)
