Sheetmetal generally comes in three forms—mild steel, aluminum, and stainless steel. Of these, aluminum and mild steel are by far the most commonly used for automotive projects. Sheetmetal fabricators prefer aluminum for dashboards, bulkheads, and most other purposes because it is light, soft, and easy to work with.
How do you fix cracked metal without welding?
Another effective way the cracks can be fixed without welding is brazing. Unlike the traditional welding technique used to repair metal items, brazing uses minimal heat to fix your cast iron pieces. This technique is commonly used to correct cracks on cast iron items.

How to repair a crack in a sheet metal airplane?
The common fix is to "stop drill" the crack with a small diameter drill bit. In other words, you drill a small hole at each end of the crack in the hope of stopping its growth. This fix is not a repair. To repair the crack, after you stop drill it, rivet a small sheet metal patch of the same type and thickness metal over the crack to restore the area's strength and to keep vibra tion from acting on it further (see Figure 1).
How to remove rivets from sheet metal?
When removing rivets, do not drill any farther than the rivet head. Do not attempt to drill into the sheet metal itself. After drilling into the head, use a pin punch to pry off the rivet head. Then use a punch smaller than the rivet shank to drive the rivet out of the hole. Your goal is to remove the rivet without enlarging its hole or damaging the sheet metal.
Why are rivets missing?
Finding missing rivets is not uncommon. Their loss could be the result of improper installation, corrosion, or some sort of underlying damage. You need to find out why it's missing and investigate the surrounding area for additional damage. Look for damaged rivets, the heads of which may be slightly slanted or raised. If you can place a 0.020-inch feeler gage under the rivet head, it's been stretched-an indication of damage.
How to determine strength of rivet?
The strength of a riveted piece is based upon the rivet's expanded diameter. This is why it's important to drill out the rivet using the proper size drill and to replace it with a rivet of the proper diameter and length. The length must be such that the shop head (driven head of the rivet) must expand to form a head that is 1.5 times the diameter of the shank. Rivets may be cut to proper length using a rivet cutter.
What is the first step in a repair process?
The first step in any repair process is assessing the damage to determine whether it's simple or major. Minor damage to a sheet metal structure includes missing or damaged rivets, scratches or small dents, a small crack, and a corroded sheet metal surface. Damage that exceeds the scope of these items is, in most cases, major. For example, deformed rivets often indicate damage to a sheet metal structure, and your inspection should include an area well past the deformed rivets.

What is a damaged control surface?

How to secure a patch in place?
While wearing protective gloves, hold the patch where you want it and use one good tack weld to secure it in place. Check that the patch is in the correct spot and give it another tack weld. Apply a few more tack welds around the perimeter of the patch, bending the sheet metal to shape if necessary.
Can you cut a patch panel from sheet metal?
We have found that initially cutting the patch panel from your sheet metal can be a little tricky. Cutting a template out of cardboard is a great first step. Some trial fitting and trimming will make it pretty obvious when the cardboard patch is the correct size and shape; then you can trace the shape of the cardboard onto the sheet metal and cut out the patch panel.
Can you patch a car panel?
If the panel is welded to the car itself or if replacing the entire panel is not an option, then the question becomes whether to use a patch panel that is specific to that application or to fabricate one from generic sheet metal stock. If a repair patch is available, get it. It’s often a lot less time consuming to go with a preformed replacement panel than to cut, bend and form a new one.
Can you weld around the perimeter?
Now that the patch is on there, you can start stitch welding around the perimeter. To limit the amount of heat that one area sees, jump around a bit and avoid laying one continuous bead. This method lessens the chance of warping and the amount of body filler you’ll need later.
