Mag Welding Specifications For High-Strength Steel Parts 590 Mpa Or Higher (Except 1500 Mpa) - Honda 2011 Odyssey Body Repair Manual

General Information
MAG Welding Specifications for High-Strength Steel Parts 590 MPa or
Higher (except 1500 MPa)
NOTE:
If 590 MPa parts are plug or butt welded to 590 MPa or
●
higher parts (except 1500 MPa), use the following
welding wire or equivalent.
MAG welding: Metal active gas welding where the
●
shielding gas being used contains a mixture of 80%
Argon (Ar) and 20% Carbon Dioxide (CO
considered active because the CO
limited reaction with the molten weld pool.
To ensure proper weld strength when doing MAG
●
plug welding, Start welding 1 mm from the outer
circumference of the edge of the plug hole and use a
spiral torch pattern to fill in the hole.
The chart below shows the approved welding
procedures for each steel tensile strength. Failure to
observe these approved methods can result in an unsafe
repair.

Confirmation of welded state
Do a preliminary welding test using a test piece of the
same material, and confirm that the bead protrudes
from the back surface. Do the main welding in the same
manner.
