Body Panel Adhesive Vs Welding

Adhesive bonding versus welding.

Body panel adhesive vs welding. Metal bonding adhesives vs welding. Go thicker and strength drops unless you re using an adhesive with filler that s engineered for larger gaps. Perform squeeze type resistance spot welding in appropriate areas while the adhesive is uncured. Fiberglass fender flares or an aluminum naca duct to a steel body for instance.

Our 3m panel bonding adhesive is a cost effective two part epoxy adhesive for bonding replacement body panels. Welding is a very common technique for metal to metal assembly operations and in some ways using adhesive for metal is very similar. The adhesive may be combustible. Welding is a heat process and that s both it s strength and it s weakness.

The adhesive i used is an evercoat product that came in. Plug welding on a kia 1 4 works but it sucks compared to using the technology available. Do not attempt to mig weld through the adhesive. The bonding adhesive contains corrosion inhibitors to resists corrosion much better than welds or rivets helping to extend the life of the body panel repair.

Most enthusiasts don t have welding experience or the required welder and related tools. For example the lack of protruding fastener heads gives both welded parts and glued metal parts a more streamlined appearance. One advantage to panel adhesive over welding is that the lack of heat that can warp steel door or quarter panel skins. I use these products on every thing i.

Panel bonding adhesive should only be used to bond structural components such as pillars rockers or frame members when specified by an oem example. Any modern body shop that s not using it along with resistance welder weld bonding is behind the times. Consider the bondline thickness required. At the same time structural adhesive technology has been used in body shops for nearly 20 years.

Keep any mig welding a minimum of 50 mms. Set rivets or other fasteners while the adhesive is still uncured typically within 2 hours of adhesive application. From its fast convenient cartridge system the adhesive seals and bonds steel aluminum smc and frp securely in a single operation.
