Professional tool reviews for professionals
It may take a while to become proficient in the art and science of welding. First, the welder must develop technical skills for the process itself. Next, he or she must also understand the limitations of material type, size, location, power supply, budget, etc. Finally, making metal is practical, satisfactory, and (possibly) profitable. At the beginning, the first question we hear is usually: When comparing MIG, TIG or rod welding-which is the best?
The short answer is-it depends. We will guide you through the key aspects of MIG, TIG, and bar welding to help you understand the various conditions under which each process can be selected. We also discussed the advantages and disadvantages of each.
All welding processes use electrodes, filler rods and shielding gas to create a temporary atmosphere conducive to strong welding. But the welding process is different in terms of electrode consumption, filler material and source, and gas (and its delivery) in the welding area. In short-there are many ways to arc a metal with a high current to soften it and refill it.
Rod welding is a basic process. It is also relatively cheap and easy to master. This process constitutes the starting point for many novice or amateur welders to learn the welding process.
We call bar welding "primary" because the welder only needs to select the appropriate electrode and current intensity. Every welding process requires shielding gas. In the case of rod welding or SMAW processes, consumable electrode rods provide this. The rod is coated with flux, and when it is ignited by an electric arc, a shielding gas is generated. Then the electrode becomes molten metal and hardens into beads.
You can do many things with rod welding-especially with some practice. Rod welding is also suitable for contaminated or dirty materials (use the correct electrode selection). You can also use this process on AC and DC power supplies. However, it is messy. Rod welding will produce fumes, splashes and slag, which requires some time and effort to clean up.
We also found that bar welding is not the best choice for very thin or very thick materials or any type of aluminum. The best illustrations we found came from the IOC website:
MIG is a bit complicated because the welder has to choose not only the electrode and amperage, but also the voltage, wire speed, and shielding gas. The MIG welding process also becomes more expensive than rod welding because you provide shielding gas from the tank. These usually use a 75/25 argon/carbon dioxide mixture. The consumable electrode is also fed from a spool located in most welding machines.
There seems to be a lot to manage welding wire, wire feed speed, gas, amperage and voltage. Finally, practice and experience can help you quickly use the MIG welding process to make some professional-looking welds.
Those who are new to welding can actually master DC-powered MIG welding in a relatively short time. This process will not produce smoke, slag and spatter close to the rod welding. This means less cleanup work. When comparing MIG, TIG and rod welding, cleanup is definitely an equation.
Welders can also use the fast travel speed of the MIG welding torch to work quickly. MIG is also suitable for thinner materials. However, with MIG welding, your material must be cleaner than using rod welding. Of course, we always recommend using clean materials-don't be lazy!
MIG may be difficult to use outdoors because the wind will blow away the shielding gas and cause damage to the weld. For this reason, sometimes it is appropriate to use flux-cored wire electrodes on MIG spools. This is similar to the flux electrode in bar welding. In this way, welders can abandon gas tanks and rely on flux to protect the welding process.
TIG welding has the most variables, requires the most skills, and is by far the most expensive of all welding processes. We also found that it is the most versatile welding process because it can weld the most metal thicknesses and types. This includes aluminum, making it suitable for many automotive jobs. It is also used in art and any welding, and the result will be very obvious after completion. This is related to the cleanest and most beautiful weld produced by TIG welding.
TIG welding uses AC or DC power supply and does not consume its electrodes. It provides the welder with maximum control, because one hand holds the electrode, the other hand holds the filler rod, and the foot pedal adjusts the amperage. Of course, this requires more coordination than any other welding process.
If you drive a stick, you should be doing well!
With TIG welding, you can also reduce the current to a very low level to prevent porosity in the material. However, this is a slower process and the material must be very clean. TIG is also particularly effective for aluminum-this is impossible, or at least much more difficult in other welding processes.
We can summarize most of the basic details and characteristics of MIG, TIG or rod welding in this useful chart:
Our goal in comparing MIG, TIG and rod welding is not to guide you in a specific direction at will. Instead, we want to help you understand the differences in cost, materials, and required skill levels. It also helps to understand the concept of shielding gases—especially about how they fail in outdoor wind.
Our "favorite" welds are often TIG welds. For those who are really good at this process, it seems to be a real art form. Nevertheless, MIG welding has become very approachable-even for hobbyists who wish to start.
For those interested in becoming a welder through trade, you want to learn all three core processes. You also want to be very proficient in every aspect. When the job requires it, the best welders move from one process to another. Whether you use MIG, TIG or rod welding, your welds will be cleaned up, and all your welds will look clean.
Now, it's time to start working. Happy welding!

Not long ago, we wrote an article on how to install a Simpson Craftsman door on a cottage house in the 1920s. This is an incredible update that really shows the charm of the wrap-around porch. Recently, we had the opportunity to follow up and review one of the Simpson barn doors of Pro Tool Reviews. [...]
