Welding is a process of joining two pieces of metal together by heating them until they melt and then fusing them together. It’s a common misconception that you can weld with a soldering iron. While both welding and soldering involve melting metal, the two processes are quite different and a soldering iron cannot be used for welding.
Types of Welding
There are many types of welding, but the three most common are Stick, MIG, and TIG.
Stick welding is the most basic form of welding. A electrode is attached to a holder and connected to a power source. The electrode is then placed on the metal to be welded and melted. The molten metal cools and fuses the two pieces of metal together.
MIG welding is similar to stick welding, but instead of using an electrode, a wire is used. The wire is fed through a hose from a spool and into the welder. This type of welding is great for large projects or projects that require long continuous welds.
TIG welding uses an arc between a non-consumable tungsten electrode and the metal being welded. A shield gas is used to protect the electrode from oxidation.
There are many more different welding types, but these are the most common in construction.
Difference Between Welding and Soldering
Welding and soldering are two processes that are used to join metals together. Both processes involve heating the metals to be joined, but there are some key differences between the two.
Welding is a more permanent way to join metals together. The heat from welding melts the metals, which creates a strong joint between them. Welding can be used on thicker pieces of metal than soldering.
Soldering is a less permanent way to join metals together. The heat from soldering melts a small amount of metal, which creates a weak joint between the two pieces of metal. Soldering can only be used on thin pieces of metal.
Welding is typically used for larger projects, where more strength is required. The heat from welding melts not only the base metal, but also the filler metal. This creates a stronger bond than soldering.
Soldering is typically used for smaller projects, or for projects where a less visible joint is required. The heat from soldering only melts the filler metal, not the base metal. This creates a weaker bond than welding, but is sufficient for many applications.
So, when choosing a method of joining metals, it is important to consider the size and strength requirements of the project.
Why Can’t You Weld With a Soldering Iron?
Welding is a process of joining two pieces of metal together by heating them until they melt and then fusing them together. It’s a very strong way to join metal, but it’s not something that can be done with a soldering iron.
A soldering iron is simply not hot enough to weld two pieces of metal together. The temperatures required for welding are much higher than what a soldering iron can produce. Additionally, the tip of a soldering iron is too small to create a proper welding bead.
So, while you may be able to use a soldering iron for some light metal work, it’s not going to be able to weld two pieces of metal together. If you’re looking to do any serious welding, you’re going to need to invest in a welder.
Useful Welding Tips
If you’re planning on doing any welding, whether as a hobby or professionally, there are some things you should know. Here are some useful welding tips:
- Always use the correct safety equipment. This includes a welding helmet, gloves, and protective clothing.
- Make sure your work area is well-ventilated. Welding produces harmful fumes that can be dangerous to breathe in.
- Be aware of your surroundings. Keep flammable materials away from your work area, and make sure there is no one else nearby who could be injured by sparks or heat.
- Know your equipment. Read the owner’s manual for your welding machine and familiarize yourself with its controls before using it.
- Choose the right electrode. The type of electrode you use will depend on the material you are welding and the type of weld you want to make.
Useful Soldering Tips
If you’ve ever worked with electronics, you know that soldering is an essential skill. Here are some useful soldering tips to help you get the best results:
- Use the right type of solder. There are two main types of solder: lead-based and lead-free. Lead-based solder is easier to work with and produces a stronger joint, but it’s not as environmentally friendly. Lead-free solder is more difficult to work with, but it’s better for the environment.
- Use the right type of flux. Flux helps to clean the metals being joined and prevents oxidation. Rosin flux is the most common type of flux, but there are other types as well. Choose the right flux for your application.
- Clean the metals being joined. Solder will not adhere properly to dirty or oxidized metal surfaces. Clean both work pieces with a wire brush, and wipe them down with a solvent such as acetone.
- Don’t overheat the solder. Solder flows more easily when it’s melted, but if you melt it too much, it can become brittle and crack under stress.
- Keep your solder tip clean and shiny. You want to see a bright reflection when it’s tipped up to the light. If you don’t, give it a good scrub with a sponge or brush.
Can you join metal with a soldering iron?
Yes, you can join metal with a soldering iron. The process is called soldering, and it involves heating the metal to a high temperature and then applying a solder to the joint.
Can you use solder to weld steel?
No, you cannot use solder to weld steel.
Is solder as strong as weld?
Solder is not as strong as weld, but it can be used to join two pieces of metal together.
Is silver soldering as strong as welding?
Welding and silver soldering are both strong joining methods, but welding is typically stronger. This is because welding involves melting the metal and fusing it together, while silver soldering relies on a lower temperature to create a bond between the metals.
What can you use instead of welding?
There are a few alternatives to welding, depending on what you need to do. For joining two pieces of metal together, you could try soldering or brazing. If you need to cut through metal, you could use a plasma cutter or an oxy-acetylene torch.
What metals cannot be soldered?
There are a few metals that can’t be soldered, including aluminum and stainless steel. These metals have a higher melting point than the solder, so they can’t be joined together using this method.
How do you join two pieces of metal without welding?
There are a few ways to join two pieces of metal without welding, including using screws, nails, or rivets. You can also use adhesives or tape to hold the pieces together.
Is electronics glue as strong as welding?
No, electronics glue is not as strong as welding. Welding is a stronger joining method because it uses heat to melt the metals together, creating a very strong bond.
Which is stronger brazing or welding?
Welding is stronger than brazing. Brazing is a process where two pieces of metal are joined together by melting and flowing a filler metal into the joint, while welding is a process of joining two pieces of metal together by using heat and pressure to create a strong bond.
Is soldering a strong bond?
Yes, soldering is a strong bond. When done correctly, it can create a joint that is just as strong, if not stronger, than the surrounding materials.

You can weld with a soldering iron but it is not recommended. The heat from the iron is not enough to weld most metals and will not create a strong joint. If you are looking to weld, invest in a welder that is specifically designed for the job. Thanks for reading!
