How to Weld Aluminium without a Welder

Welding aluminum without a welder can be done with common household items. It is an inexpensive and often faster way to weld aluminum than traditional welding methods. This guide will teach you how to safely and effectively weld aluminum without a welder.

Basics of Aluminum Welding Without a Welder

Aluminum welding without a welder is known as “cold welding” or “cold soldering.” Cold welding requires no heat, electricity, or additional equipment—all you need are the two pieces of aluminum you want to join together and some common items from around the house.

Materials Needed for Cold Welding Aluminum

To cold weld aluminum, you will need aluminum foil, rubbing alcohol, baking soda, and super glue. The rubbing alcohol helps to clean off any dirt or grease on the aluminum before the process begins; baking soda acts as an abrasive that helps create friction between the two pieces of metal; and the super glue helps hold everything in place when it’s time to solder. Depending on your application, you may also need other tools, such as pliers and wire cutters.

Welding Process Overview

The actual welding process itself is relatively straightforward. First, clean both pieces of aluminum with rubbing alcohol so that they are free from dirt or grease; this step is essential for successful cold welding. Then mix equal parts baking soda and super glue until it forms a paste-like consistency; this paste should be spread onto one side of each piece of metal before they are put together. Lastly, use pliers or wire cutters to firmly press the two pieces together until they form one seamless metal. This method works best when plenty of pressure is applied to both sides of the metal—the more pressure applied, the stronger the bond will be once it has cooled down completely!


Cold welding aluminum without a welder requires some know-how. Still, it can be done with common home materials like aluminium foil, rubbing alcohol, baking soda & super glue. The process involves cleaning both pieces of aluminium with rubbing alcohol & then applying a paste made from equal parts baking soda & super gluing onto one side of each metal piece before putting them together & pressing firmly until they form one seamless piece of metal. Cold welding aluminum is an inexpensive and often faster way to weld metals than traditional methods – so if you’re looking for an easy way to weld aluminium quickly & cost-effectively at home – this method could be perfect for your next project!
