Welding vs Brazing vs Soldering!
The most confusing term you are facing right now that makes you crazy?
You’ve heard the advice a million times; Brazing is similar to soldering and welding in that both are joining processes to join metals together.
But what’s the big difference between soldering versus welding?
It’s the question you secretly dread to ask a senior welder. Well, all of these use to join two separate metal or surfaces together. But the main difference is actually on the melting and the strength of the connection.
Want to know more about these terms?
Let me explain. Stay along.

Are Soldering and Welding the Same Thing?
There are several popular methods of joining metal. Such as:
Of course, there are some common applications and advantages, but they are not the same. Welding is most commonly used in manufacturing and construction, while soldering is often used in electrical work.
I’ll walk you through the whole process of comparison.

What is welding?
For welding, it is important for the two metals to be similar. To give an example, silver cannot be welded to copper.
Meanwhile, Welding uses high temperatures to melt as well as to join two metal parts. In most cases, A filler metal is used. After the process is done properly, the finishing will be as strong as the surrounding metal. There are various types of welding process.
So you want to know how welding works?
Welding is the process of melting the base metal to join to something else, usually the same metal. It may or may not require adding extra metal. However, brazing and soldering melt the filler metal.
So if you want the strongest bond for your metal, then welding is the way to go.
What about the types of welding?
Well, there are various types of welding. Some of these are:
- Glass welding.
- Flux-cored arc welding.
- Electric resistance welding.
- Electroslag welding.
- Gas metal arc welding.
- Gas tungsten arc welding.
- Oxy-fuel welding.
- Plastic welding.
- Submerged arc welding.
- Shielded metal arc welding.
Cost of welding
The safety and effectiveness of welding work does come at a cost. Depending on the type of material being welded, the tools and equipment required, and other factors such as previous experience, welders can expect to pay between $600 – $3,000 per day for their services.
This might not sound like a lot but if you do this for a living day in and day out it can make a big dent in your wallet before you know it.
What is soldering?
Soldering is mostly similar to brazing. So first, let me discuss brazing.
So what is brazing?
As the names state, brazing means to fix something. A brazed joint is made differently from a welding joint. The main difference is in temperature – in brazing, it’s not necessary to melt the base metals.
Now come to the soldering definition. Soldering is more likely brazing, where an alloy flux is heated to the melting point and applied to a particular component.
Now let’s see the difference between brazing and soldering.
There are some major differences. The main difference between soldering and brazing is, the flux becomes molten at a very low melting point than brazing.
How strong is soldering?
Brazing and soldering, both can be strong enough. If the shape of the base part is quite critical, then brazing can be superior for your purpose.
How does soldering work?
Soldering joins materials or metals, together usually by melting filler metal into the joint. Hence, nowadays soldiers apply lead-free alloys for various applications in the plumbing and electronics industries using metals including iron, gold, silver, brass, and copper. These are also known as soldering metals.
Types of soldering are the following:
- Soft soldering.
- Hard soldering.
Cost of soldering
The process of soldering can be performed on many different types of materials, depending on the type of metal and the part. Basic soldering iron with a heating time of 10-15 minutes will cost around $100-$150, depending on your location.
For small projects, you may only need to spend $20-$30 for solder wire and flux, but for larger projects it’s important to invest in quality material that will last longer.
How strong is soldering & welding?
Welding and soldering are two popular methods of joining metals together. They are both strong methods of joining, but which one is stronger?
Both welding and soldering are strong methods of joining, but welding is stronger. This is because welding creates a much stronger bond than soldering.
Learn the distinct contrasts
Of course, both work for jointing material. But there is some major difference. Let’s see some of these.
First and foremost, let’s talk about the joint. Welding joints are stronger, then soldered and lastly brazed joints.
Pretty interesting, isn’t it?
Now, look at the heating process. In welding, the metal base is eventually heated and melted. On the other hand, soldering doesn’t require any heating. Meanwhile, in welding, Mechanical properties may change because of heating. But soldering, it remains unchanged.
Wait, there is another factor.
Welding needs about 6,500 degrees F, while soldering requires only about 840 degrees F. another important issue is the Skill requirements. Well, for welding you need more professionalism and skill than soldering.
In conclusion, soldering and welding are two different methods of joining metal. Soldering relies on melting and dissolving metal, whereas welding is a process that fuses metal together by applying heat and pressure.
Welding is usually much faster than soldering and it produces a stronger bond than soldering. The choice between the two processes often comes down to what type of material needs to be joined, as well as personal preference.
