Whether you’re a seasoned welder or your curiosity has been piqued, it’s important to understand the different types of welding that are available to you. Each technique is exclusive, find out which one is right for you and your next project!
What’s the difference between TIG, MIG, and Arc Welding? The difference between these three welding techniques is arc usage. TIG stands for tungsten inert gas and MIG stands for metal inert gas, while arc describes the distinct process that welders use to join metals together.
Currently, there are over 30 different kinds of welding methods, and some are a lot easier than others. Certain processes are more beginner-friendly, particularly the ones mentioned below. Are you unsure where to begin? You’ve chosen the right article.
What’s the Difference Between TIG and MIG welding?
The difference between TIG and MIG welding is the arc. TIG welding incorporates a long rod which fuses metals together while MIG welding uses a feed wire that creates lots of sparks, which then melt to create a welded finish.
MIG welding is more popular than TIG welding because of its diverse capabilities and ease. With MIG, you can expect to weld with a range of different types of metals, including steel and aluminum. MIG is useful for heavy-duty jobs and thicker metals.
TIG welding can be used to fuse together a plethora of different metals, but this technique is limited in its effectiveness as it cannot be completely relied upon to get the job done on thicker metals.
The biggest advantage MIG has its wire feed. Not only does the wire feed act as a filler, but it also contributes as an electrode. This allows thicker metals to be melted together without having to be heated through to its cores. Since MIG welding uses filler, you won’t have to change the wire as often.
What Is Arc Welding?
Arc welding is a technique that uses an electric arc to melt and fuse metals together. This process uses intense heat and can be done either mechanically or manually. It is also a technique that is not beginner-friendly.
Arc welding has its advantages because it offers high efficiency as well as speed. You can always expect a near-perfect quality pass with the arc weld. While welding creates a strong bond between metals, the arc is by far one of the strongest.
Arc is absolutely one of the fastest methods, but it is a rather complex skill to master. Operators must have high levels of knowledge and be able to work at an advanced, professional level.
Like most perfect things, arc welding will take practice as well as genuine effort and patience. To keep it simple, here are four steps to understand the basics of arc welding:
- Create an electric arc, also known as striking the arc, between the piece of metal you are working on and the electrode.
- Create a bead. In order to create a bead, move the arc. The bead comes from the metal that is being melted. The electrode bonds and flows with the metal, which is being melted from the extreme temperatures.
- Give your weld bead some texture and shape. To do this, move your arc in either a figure 8 fashion or get creative with a zig-zag pattern! The motions you create with your arc will help spread the metal to your desired width.
- Clean up those edges! You don’t want any leftover “slag,” otherwise regarded as melted metal. Every time you complete a pass, be sure to brush the weld. Chip away at any jagged edges in order to come away with excess melted material. Observe each pass, so only clean metal is left.
While the process of arc welding may read simply, the arc is a field that requires mastery. Don’t worry; there are other techniques that will better suit both beginners and novice welders! If you’re serious about welding, it’s best, to begin with methods that will assist you in working your way up to a mastered level. For example, TIG and MIG welding.
Which Welding Technique Is Faster: TIG or MIG?
MIG welding is faster than TIG welding. While it is still important to take your time when using welding tools, you can expect to finish your project in less time with MIG. MIG welding guns can operate continuously for extended amounts of time, which allows for higher percentages of efficiency.
If you are working on a large, industrial-sized project, MIG will make this process much smoother. Its counterpart, TIG, can still aid you greatly, but this will really slow things down as TIG is generally more focused on the finer details versus speed.
What’s The Basic Step-By-Step “At-Home” MIG Welding Process Like?
Using a simple and mechanized technique, it goes a bit like this:
- Begin by placing a fume extractor above the area you will be welding in. If you have one of these, it’s imperative to keep it near your workspace. It will run automatically if fumes are being exuded. Otherwise, make sure your space is open and breathable.
- Prepare your workspace and materials. Ensure your metals are clamped together so they won’t shift, observe your welding settings, prepare your welder by turning it on, and adjusting it accordingly.
- Set your welder’s wire feed to your desired speed. This entirely depends on the type of metal you are working with. If your wire setting is too low, you won’t be able to penetrate the metal as cleanly as you may like.
- You’re ready to weld. Touch the welding wire to your desired sheets of metals and begin fusing them together with a slow, steady hand. If your welding hand is moving too fast, you risk the chance of missing fusion sections, which could leave your project lacking in stability and smoothness.
- Observe your job. When you’re ready to take a look at your work, be sure to turn off your welding machine first to avoid any injuries or accidents.
- Clean up your workspace. Unclamp your metals from your welding table and neatly pack your MIG welder wires away. Well done, you’ve welded something!
- Practice for at least 30 minutes a day. While practicing for hours on end is usually written on curriculums and requirements alike, practicing consistently, even for shorter amounts of time, will be extremely beneficial to you and your technique.
Since MIG welding is the most basic technique that you can use, it’s easy to begin this process by simply preparing your materials and turning your MIG welding machine on. This won’t be complex or confusing because you’ll just have to follow very simple steps that don’t require much thought or mastery.
Don’t be dismayed if your project doesn’t turn out pristine the first time around. MIG welding is just the beginning of your welding career, and practice makes perfect! If you’re constantly experimenting with different temperatures and wire feeds with your MIG welder, you’ll be more aware of the potential mistakes and mishaps that could occur.
If your welds are fusing during your first pass, having that experience will only act as a learned lesson. Perhaps your speed setting was the issue, or the voltage was not quite right! With consistent practice, understanding how to adjust these things so that they properly come together will aid you in improving your overall skills.
Always remember to practice welding safety. Anyone who wishes to become a professional and advance into TIG and eventually Arc welding will never forget to be a safe welder!
Between TIG and MIG, Which Will Offer Better Quality?
TIG welding offers better quality. With TIG welding, you can expect a fine, clean-cut finish. TIG welding is on the artistic side, as it allows for craftsmanship and detail.
TIG is more commonly used for intricate projects such as ornament pieces, small repairs, and toolboxes. TIG welding is still very common and popular in large industrial workplaces. It is used to correct precise details and for specific equipment pieces in aircraft, general transportation, and, in some instances, military-grade materials.
Due to its precision capabilities, this is the method of choice for advanced welders. TIG is more stringent because of its quality control. The tungsten electrode is non-consumable; this is how the arc is formed. Experience is necessary for TIG welding because filler metal is fed in separately and gradually. This makes for more customized operation. The welder can control both depth and speed.
Which Welding Technique Is Easier To Work With?
MIG welding is easier to handle for beginners. With just a few short weeks of extensive welding training, any beginner will be able to get the hang of MIG welding. Many experienced welders will refer to MIG welding as a “hot glue gun” technique. This makes the concept easier to understand.
When starting out with MIG welding, adopting it as the “hot glue gun” technique gives the process a visual idea. Essentially, you just squeeze the trigger to begin and release it to stop. You can operate the MIG tool with just one hand, which is why it’s the top choice for beginners.
TIG welding is slightly more complex in its operation. While beginners can still learn how to operate their welding tools with this technique, it requires specialized gestures that include both of your hands, and even your foot! You’ll have to have excellent coordination to operate TIG welding because each hand and your foot will each be doing separate things.
