I-CAR will offer a hands-on MIG brazing course in January — and even cosmetic collision repairers might want to take note, an expert said.
MIG brazing, which allows joining at a lower heat, is useful for vehicles with ultra-high-strength steel (typically 781 MPa or higher). That light, strong metal and other high-strength automotive steels weaken when heat is applied.
Because of this, OEMs restrict repair procedures on high-strength steels, and auto body shops have even fewer options once the UHSS threshold is reached.
When OEMs say “no sectioning” or mandate certain types of joining, it’s not a gauntlet for your technicians to try and overcome.
Attaching the panel to the ring in a shop requires about 40 MIG-brazed joints. Spot welding (which Honda does allow on some UHSS parts, including on the MDX) isn’t possible in the space.
Honda first required MIG brazing at the outer panel level on the 2009 Acura TL. It has since expanded the procedure to the panels of other vehicles besides the MDX as they undergo full model changes, according to Tobie.
No decision has been reached on if the upcoming I-CAR MIG brazing course would be required for ProFirst shops, though it’s recommended for those businesses. Honda was a major proponent of the I-CAR-developed course, which will teach not only about MIG brazing Hondas but brazing on other OEM vehicles as well.
