Introduction 
If you face any cracking in metal objects and want to fix it without calling a welder, what will you do? We should acknowledge about few basic and easy techniques of joining metal without welding.
Welding is an expensive process of joining metal, and it also needs more technical knowledge to perform.
To start welding, you must have sufficient work experience to fulfil your need.
“How to bond metal without welding” briefs that welding may be hazardous in some cases. So, without understanding, it is dangerous.
Besides this, if you want to repair your household metal objects in case of cracking, you can use non-welding techniques. These non-welding techniques are easy to adopt and have less expensive as compared to welding.

Techniques
The adoption of non-welding practices differs according to the nature of metal and conditions. Here we discussed the few most common strategies;
-
Epoxy
Epoxy or glue is one of the most common non-welding technique. The epoxy gel is adhesive. The joining points are cleaning well to join the metal and then apply the gel over the surface. Attach both parts in the desired position and allow them to dry. This adhesive forms a firm joint after drying. But few recommendations are followed to attain desired results. Be careful in selecting epoxy, use specific gel according to the nature of the metal element as silica gel is considered best for the joining of aluminium objects. Let the parts dry entirely for a firm grip. These epoxy joined metal are not able to lift or bear heavyweight items.

Soldering
Soldering is the most ancient technique ever used for joining. It is the technique used to enter the metal objects without welding. It's different from welding. To know more learn soldering vs welding.
In the soldering process, both parts are heated and joined together, which is a fusion process. The broken pieces of metal and created by arc joined together in the desired position and allowed to cool down.
This process applies to the same metal elements as the joining of iron to iron can be done by soldering.
Two different aspects cannot be joins together using this technique due to the difference in the melting point. Strong joints make by using this process.

Nuts and bolts
Nuts and bolts are also using to fix metal objects. In this process, both metals are places in the desired position, and the whole form by using a drill machine. Bolts pass through the whole, and nuts tights up at another end of the bolt. In that way, stable joints make. The main advantage of the nuts and bolts application is that they can open easily while shifting or changing. Many billboards and other infrastructural objects are making by using this technique.
Conclusion
Does this article meet the curiosity of how to Bond metal without welding? These techniques help to reduce the use of the welding process due to their comfort level, and these are easy to adopt. Some people consider soldering is a welding process. But there is an enormous difference in soldering and welding. In the welding process, the electrode consumes to join the metal. This electrode act as a welding agent. Arc is applied to heat the metal objects and electrode. When this electrode melts, it fills the cracking point. But there is no use of electrode in the soldering process.
