How to weld without a welder?

If you are in love with DIY projects, I am sure you have come across welding projects. How to weld without a welder may seem complicated, but the job will become comfortable at the end of this article. You will be able to join two pieces of metal right at home without a welder. Welding work requires some expertise and investment as well.

You are at home, and you don’t have welders. Don’t worry because here are some of the commonly used ways to effectively weld without a welder. Bonding metals without welding can save you from hassles. Let us have a look at some of these methods.

How to weld without a welder (methods)


This becomes the most common choice for amateurs. It is the cheapest and easiest solution that I can recommend to any beginner. It makes an excellent option for non-structural constituents. It also suitable when you need to work on something light. 

However, this method only works for some metals like refined aluminum. The technique can incredibly work on this metal. When using this method, it is advisable that you practically clean the metal surface. Remember, doing so will ease bonding; a clean surface is always the best to work with.

The most common mistake associated with this method is to use unclean and unprepared surfaces. Therefore, you can easily use a metal prep to get rid of adhesion. Under this step, make sure that you are using the right pieces of stuff. Over-all purpose materials might not work for you. 


Joining metal with the aid of Nanoscale sculpting or nanomaterial remains an effective method. This method involves coarsening the surface of the metal in a precise etching way. It would help if you did this through electro-chemicals and 3D printing. 

This will then produce a hook-like construction shaped on a small scale. The two surfaces will then be connected using glue. The bond will be sturdy. This method can also be useful when joining heavy and oversized constituents together. 

You can use this method for various applications, such as the construction of ships and cars. With this method, there is no need for high temperatures that may destroy surfaces. Remember, you can carry out nanoscale sculpting a room temperature with only a few safety measures. 

This method can be suitable for various applications.

Spot welding

This is another method that you can depend on. The strategy needs a broad knowledge to perform a project. Many mechanics find the technique useful and operative to join metals without a welder. Here, you will need to have a metallic material ranging from .020 to .12 in width. You should also have two copper electrodes.

Denser metals tend to cause some problems with spot welding. So, a large electric current should comfortably flow through the electrodes. This method is cost-effective.


Soldering becomes another way that you can use to weld without a welder. It connects the two pieces of metals using suitable filler material, maintaining a temperature of not more than 450 degrees Celsius. Soldering can comfortably join, unlike metals. 

The metallic filler used here is known as solder, a combination of lead and tin. You can obtain various solder by using different ratios of tin and lead in the mixture. The most exciting fact about solder is that it can melt at lower temperatures. It has low melting points. 

Furthermore, the soldering process does not require you to melt the work parts. Soldering is suitable for various applications, such as fabrication and locomotive businesses. It is also essential in electrical contacts in radio and TV to link delicate works thermally. Occasionally, the solder is useful in joining, unlike metals.


Just like soldering, brazing uses flux blends, heat, and filler metal for fusing metals. You will have to insert the flux resolution on the metals and the filler metal for heating before joining them together under this procedure. 

Unlike welding, brazing involves heating the filler material under a lower temperature than the materials you plan to fuse. Brazing is the most suitable procedure for tinny metallic materials such as aluminum. With this method, you can easily attach two aluminum metals without destroying the base metal. This is known as metal fusing without welding.

More so, you can still use this method to join together different metals like ferrous metals. However, various applications with the brazing procedure will require fluxing agents in controlling hygiene. 


Riveting is another efficient alternative way that you can use instead of welding. It is the method for joining two pieces of sheet metals. You can quickly achieve this method by riveting one end head of the metal parts. Twist the other end to prevent it from falling over and fasten the shards together. 

This technique is compact since there are diverse rivets involved. Two types of fasteners are commonly used, i.e., blind and Tinner’s rivets. Blind rivets are silent to use because you only need to use it from one side. On the other hand, Tinner’s buckles are the most suitable type for thinner shards. 

Fasteners/screw Joint

A screw joint is a short-term joint that exists due to fastens nuts, bolts, and standoff. These materials are useful in joining two or more extra metal parts. Sometimes you may use machine screws to handle numerous disassembles and assemblies.

 However, self-tapping the bolts are not the right solution since they are only appropriate for one-time assemblage.

Frequently asked questions
