Description PrecautionsForHandling HighStrength Steel

• Alldimensions indicatedinfigures areactual ones.
• When usingatracking gauge,adjustbothpointers toequal length. Thencheck thepointers andgauge
itself tomake surethere isno free play.
• When ameasuring tapeisused, check tobe sure there isno elongation, twistingorbending.
• Measurements shouldbetaken atthe center ofthe mounting holes.
• Anasterisk

•
The electrode tipdiameter mustbereformed
properly according tothe panels thickness.
•
The spot ungget onHSS panel isharder than
that ofan ordinary steelpanel.
Therefore, forspot cutting HSSpanel, ahigh
torque drillofalow speed (1,000 to1,200
rpm) maybeused tomaintain itsdurability
and facilitate theoperation.
• HSS panels withatensile strength of785 to981 N/mm

(80to100 kg/mm
2,
114to142 klb/sq in),
used asreinforcement inthe door guard barand inthe bumper, istoo high intensile strength touse
for general repairs.Whenthesepanels aredamaged, theouter panels alsosustain consequential
damage; therefore, thesepanels arenever remedied withoutreplacing thedoor assembly orbumper
assembly.
2. Precautions inspot welding
This work should beperformed understandard workconditions. However,workcontrol mustbeexercised
