How to Repair Holes in Metal

Sheet metal is one of the most versatile materials in fabrication, used in countless applications and industries. While sheet metal is used in manufacturing because of its flexibility, it can also be prone to damage in high wear-and-tear applications.

Damage from accidents, weak spots or even poor maintenance over the years can cause holes to form in sheet metal. Rust is an especially common cause of holes in sheet metal. Whatever the reason for the damage, you have plenty of options for doing your own metal hole repair to patch up your material quickly.

The first option you have to fill holes in metal is by welding. If you want to repair a hole in a metal door or repair a hole in a stainless steel tank, then welding gives you the strongest, most permanent option. During the welding process, you apply a new layer of metal to the existing sheet metal to reinforce its durability, effectively making it thicker and stronger than it was originally.

There is a specific way to perform metal welding repair based on the type of metal and its application, such as fixing holes in a car body. Expert welders will know which type of welding technique to apply to make the repair spot strong enough to prevent future cracking. When hiring an experienced welder to repair holes in metal, be sure to ask about the technique they use, such as MIG (metal inert gas) or TIG (tungsten inert gas) arcs.

Epoxy or Tape

Epoxy and tape are two common no-weld hole repair options. These self-help methods work well for small holes rather than large ones. Specialty epoxy and tape products are designed to patch steel and metal. Epoxy can be used to fill a hole. It depends on the severity of the damage and how good the job was done. Be sure to apply a coat of primer to the patched area after you’re done to seal the epoxy and prevent the hole from reforming.

For auto body damage, duct tape or aluminum tape can be used as a quick and easy fix. It can also be painted over to camouflage the repair job. However, using tape to fix holes in a car body or any other type of metal should only be considered a temporary solution.

Using a UV Repair Patch to Fix Small Holes or Rust

For a more durable and permanent way to repair holes in metal without welding, try a UV repair patch. UV repair patches are quick fixes for small holes and rust damage. UV repair patches work by applying the patch to the hole or rusted area and waiting for the UV rays from the sunlight to activate the patch, hardening it within a few minutes after initial exposure. If you’re working in a dark spot with no access to sunlight, UV repair patches can be activated and cured with UV light emitted from a lamp.
