How To Install Patch Panels Without Welding

Views: 165 Author: Site Editor Publish Time: Origin: Site

Patch panels, also known as body repair panels, are a vital element of any auto body repair process. They are metal panels that are welded onto the car body to replace corroded or damaged panels. But if you don't have access to welding equipment or don't have experience with welding techniques, you can still install patch panels without welding. Below are the steps to follow:

Step 1: Gather Your Tools and Materials

To install patch panels without welding, you’ll need the following:

- Patch panels: You can purchase patch panels online, or at your local auto body repair store.

- Metal cutters: You can use a jigsaw, angle grinder, or electric shears to cut the patch panels.

- Drilling machine: You’ll need a drilling machine to drill holes in the metal panel.

- Sandpaper: This will help you prepare the metal surface for bonding with the patch panels.

- Threaded rods: These will be used to hold the patch panels in place.

- Bonding agent: You can use a bonding agent such as an adhesive or epoxy to bond the patch panels to the car body.

Step 2: Remove the Damaged Panel

Remove the damaged section of your car’s body. Use a cutting tool to cut the damaged panel away, leaving a clean and flat edge. Sand the surface around the edge of the hole with sandpaper to remove any paint or primer.

Step 3: Cut the Patch Panel

Place the cut-out patch panel on top of the hole, and use it as a template to mark the contour of the outline on the metal sheet. Use metal cutters to cut the patch panel to fit the hole precisely.

Step 4: Drill Holes to Insert Threaded Rods

Drill two holes on both sides of the patch panel. The holes should be slightly smaller than the diameter of the threaded rods. The threaded rods will hold the patch panel in place during the bonding process.

Step 5: Clean the Surface

Clean the surface around the hole using sandpaper. Remove all debris, paint, and rust from the area to ensure a better bonding surface.

Step 6: Bond the Patch Panel

Apply the bonding agent onto the surface of the car and the patch panel. Place the patch panel onto the hole and insert the threaded rods through the holes. Tighten the nuts on each side of the threaded rods to hold the patch panel in place. Allow the bonding agent to dry.

Step 7: Remove the Threaded Rods

After the bonding agent has fully cured, use a cutting tool to cut off the excess threaded rods on both sides of the patch panel. Sand the surface if needed.


Installing patch panels without welding is a quick and easy way to repair your car’s body. However, it is important to remember to use a bonding agent that is strong enough to hold the patch panel in place. Follow all steps carefully and you’ll have your car looking as good as new in no time.
