High-Strength Steel (1500 MPa) Parts Welding Specifications
High-Strength Steel (1500 MPa) Parts Welding
Specifications
The high-strength steel (1500 MPa) material is used for
the front pillar area, the roof side area, the center pillar
area, and the side sill area of the vehicles.
Parts replacement for the reinforcement and/or the
stiffener may be required depending on the damage to
the side panel. Take notice that spot welding conditions
for welding the replacement parts differ from the normal
welding conditions. MIG brazing must be used where
spot welding cannot be done. NEVER perform MAG
welding.
MIG brazing welding method
To ensure adequate joint strength, use a pulsed MIG
welder with specified wire and the following brazing
technique. This will create a capillary action in order to
liquefy the solder so that it can penetrate into the upper
and lower plates:
Begin brazing about 5 mm (0.20 in) before the hole(s).
●
Move the torch across the hole in a zigzag pattern as
●
you close the hole(s).
Continue the brazing operation about 10 mm (0.39 in)
●
past the hole(s).
Spot welding specifications
Current: 9000 A
●
Pressure: 3432 N (350 kgf, 772 lbf)
●
Welding cycle: 26
●
NOTE: When spot welding is performed, make sure that
the following conditions are maintained: the specified
current, conductivity time, welding pressure, holding
time, and shutdown time recommended for spot welder.
Follow the spot welder manufacturer's instructions.
MIG brazing specifications

●
Wire: CuSi3
●
Shielding gas: Argon gas (100%)
●
NOTE:
For details about correct brazing current and voltage,
●
refer to the equipment manufacturer's
recommendations.
MIG welding/brazing: Metal inert gas welding or
●
brazing where 100% Argon (Ar) shielding gas is used.
Argon is inert and does not react with the molten weld
pool or brazing operation.
Brazing hole size
For joining, or brazing of stiffener (340 and 980 MPa) and
the high-strength steel (1500 MPa) parts: Drill two holes
φ8 mm (0.31 in) in about 10 mm (0.39 in) pitch.

For joining, or brazing of outer panel (270 MPa) and the
high-strength steel (1500 MPa) parts: Drill one hole φ8
mm (0.31 in) at the outer panel.
