Unitized Body Structural Repair
which statement describes UHSS (ultra-high strength steel) - ANS-Can be heater following
manufacturer's recommendations
If a manufacturer places a three minute time limit on heating HSS (ultra-high strength steel), this
means that heat can be applied - ANS-for a total of 3 mins
heat crayons indicate their rated temp when they - ANS-melt
HSS parts should be replaced if they - ANS-are kinked
if an overpull occurs - ANS-the part generally must be replaced
tensile straight is the amount of pressure or force required to cause a - ANS-tear
HSS can be identified by - ANS-referring to the body repair manual
unibody structural panels should be welded by which of the following methods - ANS-mig
welding
the recommended shielding gas for welding steels in collision repair is - ANS-75% AR/ 25%
CO2
porosity in the mig weld may be due to - ANS-lack of shielding gas
metal distortion and tearing during pulling can be minimized by - ANS-using multiple pulls
which of the following uses heat by an electric arc to fuse base metal in a weld joint - ANS-flux
coated
what precautions should the mechanic observe when welding - ANS-all of the above
when mig welding on zinc coated steel the mechanics should - ANS-turn the welder up to the
next higher heat and wire speed setting for the same thickness of non coated metal
some manufacturers use foam fillers in a and b pillars and other locations what should a
technician do when repairing these parts - ANS-if the foam cannot be replaced, minimize
welding by using tack welds
structural parts - ANS-must be mig welded
