Unitized Structural Body Repair Exam
.023 Wire - ANSWER-Most commonly recommended wire size
6 - ANSWER-Chemical Make-up / Higher the number, better wire
70 - ANSWER-Tensile strength Expresses in Thousands of PSI (70,000)
A-Pillar - ANSWER-The pillar or the vertical bar which you see holding the windshield
from sides, the right side A- pillar houses the Antenna in most of the cars
Abrasive Wheels and Bits - ANSWER-Grinds away weld nuggets. Base metal stays
intact but throws metal and sparks all over. (MESSY)
Air Chisels - ANSWER-A flat blade. Thinner metal is torn easily. Use to finish after
welds have been cut with another too.
Anchoring - ANSWER-Procedure for vehicles without vertical rocker pinchwelds. Upper
body ____ insures pulling forces are not transmitted into undamaged portions of the
structure. Also allows proper alignment to the adjacent panels that are not damaged,
and prevents the possibility of tearing the repairable parts or causing further damage.
Areas to Avoid - ANSWER-Crush Zones, Complex Structures, Mounting Locations,
Large Holes (in excess of 1/4)
Asymmetrical - ANSWER-Unequal on each side of the vehicle. (spare tire well)
AWS - ANSWER-American Welding Society Standard
B-Pillar - ANSWER-The pillar on both sides just behind the driver's seat.The pillar which
is present in between the rear & the front door.
Butt Joint with Overlap - ANSWER-Performed much like a staggered butt joint, but the
panels overlap 1/16 to 1/4 to restore strength lost when welding HSS.
Butt Joints with Insert - ANSWER-Works well on closed sections such as rockers,
pillars, and rails. The additional layer provided by the insert has several roles, improved
fit up, replacing strength lost when welding HSS and preventing burn-through on thin
sheet metal.
C-25 - ANSWER-Shield Gas, 25% Carbon Dioxide and 75% Argon
C-Pillar - ANSWER-This is where the rear window ends but on the body & not on the
door.
, Centerline - ANSWER-Vertical plane that passes from the front of the vehicle to the
rear. Measures Width. May have stamped marks on vehicle body structure. Is confirmed
by referencing at last 3 width measurements in the undamaged portion of the vehicle.
Collision Energy Management - ANSWER-Goal is passenger protection. Front and rear
structures act as crush-able energy absorbers.
Compound/Stepped Drill Bits - ANSWER-Faster than a hole saw, but leave a hole in
base metal. (when welding CAN NOT be performed from the backside this option is
unacceptable.)
Compression Spot Welding - ANSWER-Used by manufactures, but is not
recommended for collision repair. Our equipment makes welds 70-80%of the strength of
manufactures. Manufactures may have technicians use but must follow service manual
and special procedures.
Computerized Measuring System - ANSWER-compare data stored in a software
program or a central database. Get hard copy of measurements. Can watch while
pulling.
Conversion Coatings - ANSWER-Follows the metal conditioners and lays down a zinc
phosphate layer that maximizes primer adhesion as well as preventing rust "creep"
under the painted surface. Not to be used in enclosed sections.
Corrosion Protection - ANSWER-Zinc based coatings. Zinc rich weld thru primers, Acid
based metal cleaners and etchers, conversion coatings that form a zinc poshpate layer,
Paint Finishers-sealers, color and clear coats, seam sealers at panel joints and seams,
petroleum and paraffin based compounds.
Crush Zones - ANSWER-Structural components such as rails are designed to collapse
and bend at specific points.
Datum - ANSWER-Imaginary plane or line beneath the vehicle. Measures height.
Datum Measurements - ANSWER-Taken at Datum plane, height differences between
reference points. Laser measuring system
Direct Damage - ANSWER-POI. Easily located and diagnosed.
Duty Cycle - ANSWER-Amount of actual welding time.
E - ANSWER-Type of standard-ELECTRODE
