![]() On Target also provided reader-friendly explanations on the differences between pull-style, self-piercing and flow-form rivets. It helps drive home Ford’s assertion that rivets aren’t necessarily interchangeable, and often neither are riveting tools. Rivet-bonding avoids those heat complications and creates too tight a fit for corrosion to occur, according to On Target. Ford might be able to spot-weld aluminum, but your shop can’t - and your attempting to do so might harm the metal and yield an unsafe repair.īesides, Auto/Steel Partnership research has demonstrated that a combination of rivet and adhesive can bond two pieces of ultra-high-strength steel better than a factory spot weld.įord explained in On Topic that aluminum welding needs triple the power of steel, can make the metal brittle and can be compromised (insufficient penetration) by the oxide layer quickly arising on aluminum. This is an important reminder to follow the OEM repair procedures, even when those instructions call for a method different than the factory’s. ![]() “Aluminum welding requires highly specialized weld units and procedures (pre-heating and post-heating), along with a slow cool down, that make it unfeasible for the average repair shop,” Ford wrote. The fall 2018 edition explains why an OEM might want collision repairers to rivet-bond their aluminum parts with a combination of a fastener and adhesive rather than pull out a welder.Īccording to Ford, spot-welding aluminum is difficult for an OEM, and it can’t be done in the aftermarket. ![]() ![]() Estimators, technicians, owners and insurers unfamiliar with riveting operations should check out a helpful primer contained within Ford’s latest On Target newsletter. ![]()
