what rod to use when tig welding auto bodywork

Whether you lot're a beginner or an established welder, you need to acquaint yourself with knowledge of welding rod sizes.

Welding rods help in joining metals together. They also determine the strength of the bond holding both metals together.

So, choosing the appropriate welding rod size is crucial. That's because choosing the wrong welding rod would produce a weaker weld. Consequently, all your efforts would be in vain.

You surely practice not want that. I, for one, wouldn't want that as well. Welding rod size is a broad topic, and the myriads of rod sizes out there make choosing the right one more than confusing.

This guide will discuss different welding rod sizes, types, uses, and many more. Then, don't go away. Continue reading.

Welding Rod Sizes And Classification

 It'due south not enough to take clues about welding rod sizes. One should also learn almost their uses, pros, and cons to make an informed decision.

There are 7 sizes of welding rods out at that place. They are 6010, 6011, 6012, 6013, while the rest is 7014, 7018, and 7024.

It would interest you to know that each of these rods has varied characteristics, such every bit tensile force, position, penetration, and others.

Before nosotros go deeper into welding rod sizes, including their uses, allow's discuss welding rod classification.

What does welding rod nomenclature  entail?

Before y'all buy a welding rod, bank check the rod properly. You'll find a gear up of numbers imprinted on information technology. The numbers mean something, which every welder is supposed to know.

Let'southward expect at a welding rod with the figures 6010. What does each number entail?

The first ii numbers, "60," stand for how much stress the weld beads can handle. Since it's "60", information technology, therefore, means that the rod tin can take 60,000 pounds per square inch.

If the effigy is higher, the rod will be stronger. That's something yous should know.

The tertiary number also means something. Since the electrode used every bit an case is the 6010, then the third number is "i".

The 3rd number talks almost the position you tin can use the rod. Since it's "1," and so you tin use the rod in all positions.

The quaternary and final number is also crucial. And so, don't neglect it. The number gives an idea of the coating that has been used on the electrode. It also influences the currents one can use.

Here's a table showing the various welding rod sizes, tensile force and other crucial information nearly welding rods.

Welding Rod Sizes And Their Uses

1 reason to learn about welding rod sizes is because of their uses. Each welding electrode is suited to a specific welding project.

If yous mistakenly apply the wrong welding rod, the weld won't be appealing or durable. It would be a waste of time and endeavour for yous.

So, here are the various welding rods, including projects they are platonic for.

Essential Things To Consider Before Picking Welding Rod Size

Whatever welding rod you cull should exist able to meet your unique needs. This means that y'all must pay attending to several factors before making your final selection. At present the question is, what are these factors? Why should you fifty-fifty bother to pay attending to them?

If you desire your welds to be durable and pleasing to gaze at, you should consider using the ideal welding rod.

Alright, permit'south look at factors to consider as you make moves to buy a welding rod.

Gene#1: Electric current available:

There are ii specific options when information technology comes to electric current. This includes Air-conditioning and DC. Some electrodes connect to either or both.

So when buying your electrode, choose i that would be useful, based on the available electric current in your workshop or project area.

Another affair you need to take in heed is that current influences penetration.

Cistron#ii: Tensile strength:

 Tensile strength is a big deal when buying electrodes. If your rod's tensile force doesn't lucifer the base metal, you're going to likely experience cracks, including other inconveniences that come with using rods with depression tensile strength.

So, cheque the tensile strength of the rod before splashing the cash. It would be best if you asked this question. Does my rod'south minimum tensile strength lucifer that of the base metallic? If yes, and so go ahead and splash the cash on it.

How can you decide a welding rod's tensile forcefulness? Information technology's elementary. We have also shared tips on this at the beginning of this mail. But allow'south become over it once again.

If the welding rod reads 7028, the showtime two numbers (70) indicate the rod's tensile strength. In this case, the rod's tensile force is seventy,000 pounds per foursquare inch.

Factor#3: Welding position:

Welding position is another disquisitional factor that shouldn't exist overlooked. But the good thing is that you tin determine your welding rod'south position from the number printed on information technology.

Look at the third number printed on your welding electrode. If the number is "i", and then the rod can weld in any position. That is horizontal, overhead, vertical, and apartment.

However, if the 3rd number is "2", so the welding position will be horizontal.

Factor#4: Base metal:

The base metal is also crucial. What's its shape, joint fit-up, and thickness? All these are what you should consider.

If the base of operations metallic is thick, your welding electrode should not but boast low hydrogen just exist highly ductile. Why? Some may ask this question. Well, the reason is to ensure that the electrode doesn't end up bully.

So, if your base metal is a thick one, please choose the appropriate welding electrode. How practise you determine which electrode is suitable for your thick base metal? Information technology'southward also simple.

You can determine which electrode is platonic for the base metallic you're using via the end digits on the electrode. For better agreement, utilise rods that end with 15, 16, or eighteen.

Please keep in listen that the electrode used for thicker base metals is unlike from thinner metal. For thinner metal, you demand electrodes whose penetration is shallow, and the arc is soft. Using a welding rod with deeper penetration will but get the material burnt.

So, if you're using a thinner base metal, the 6013 electrode is a much better choice for you.

Pro Tips: The 6012 welding rod is ideal for wider openings. It's excellent at making groove welds and bridging such wider gaps. However, if a joint's fit-up or design isn't beveled, using the 6010 and 6011 electrodes. These offer deeper penetration and should be able to become the task washed satisfactorily.

Welding Rod Types

There is a demand for welders, beginners, and professionals to obtain more cognition on welding rod types. In as much as electrode size matters, types affair too.

The 2 types of electrodes in existence are consumable and not-consumable electrodes. Nosotros'll be sharing more information on both.

If you prefer TIG welding, the consumable rod is what you should exist gunning for. The exception is when using an arc welder together with a carbon electrode.

The carbon rod is non-consumable and comes made of carbon graphite.

Alright, allow's hash out what the two types of electrodes we mentioned entail.

Consumable welding rod:

Consumable electrodes are electrodes that experience significant changes to their construction when used. What this means is that they cook during the welding process. And after melting, the consumable electrode mixes with the weld, making the bond belongings both metals in place stronger.

However, consumable electrodes happen to be the most common type of rod out in that location. SMAW (Shielded Metal ARC Welders) and MIG (Metal Inert Gas) welders utilize them.

Pro Tip: Stick welder is another proper noun for Shielded Metal ARC Welders.

Your choice on whether to cull a consumable electrode or not depends on the metal yous're welding. Consumable rods are improve when used in impurities elimination.

The Non-consumable welding rod:

The non-consumables are different from consumable electrodes in that they don't cook during the welding procedure. Examples include carbon and tungsten electrodes.

But the tungsten electrodes, which are used for TIG welding, happens to be more popular than carbon electrodes in residential and industrial applications.

Alright, let's discuss both electrodes, talking nearly tungsten and carbon rods.

Tungsten welding rod:

These electrodes, equally nosotros said before, are popular than carbon electrodes. They are too used with the TIG welder.

Some other unique thing nigh tungsten rods is how they are made. They are made with either pure tungsten or tungsten and a combination of thorium or zirconium.

Pro Tip: Pure tungsten rods are more suitable for smaller projects where the metals are tiny. These types of projects don't usually demand high amperage.

What'south unique about tungsten and zirconium electrodes?  Dissimilar pure tungsten, you can use tungsten fabricated with zirconium for welding heavier metals. The simply matter you lot have to be wary about is the weld. The bail won't be as durable as tungsten plus thorium weld.

What's unique near the tungsten and thorium electrodes? This electrode is the virtually pop amongst all three tungsten rods. It uses high amperage and tends to generate a stronger bond.

Hither is a tabular array showing the various types of tungsten rods, including identifying them by their colors.

	Tungsten Welding Rod	Color Classification
1.	Pure Tungsten	Green
ii.	i% Thorium	Yellowish
3.	2% Thorium	Blood-red
iv.	iii to 5% Zirconium	Brown

Carbon welding rod:

The CAW, or carbon arc welding, has been effectually for donkey years. Information technology's also less mutual in welding shops and home workshops. Information technology boasts an arc welder setup that'due south quite different from the standard one in use.

Pro Tip: AWS (America Welding Order) has seized to provide specifications for carbon arc welding.

Nevertheless, this doesn't mean that CAW (Carbon arc welding) is no longer in use. Information technology'southward just not in faddy anymore.

Carbon arc welding is withal beingness used in the Usa military to heat and cut metallic to size.

The welder setup will announced weird if you lot oasis't used this type of welder before. Information technology's different from the typical welder setup for arc welding.

Carbon arc welding utilizes ii non-consumable carbon rods. The rod produces a big arc, making it more challenging to control than other arc welding processes.

But so, this gigantic arc produced gives carbon arc welding a vast advantage. It makes information technology more platonic for heating metals and cutting channels or holes into metals.

Pro Tip:  Carbon arc welding is fantabulous for welding more than extensive metals. But you tin't say the same thing for thin metals. It'southward not designed to behave out detailed welds on such metals.

Conclusion

So, these are the welding rod sizes on the market. We besides provided details of their classifications, specifications, uses, and factors you need to consider before choosing a welding rod.

Welding rod makes welding possible. Without information technology, information technology would be impossible to join metals together. And don't forget that choosing the right welding rod matters a groovy deal. It would make up one's mind whether your welds would last long or non.
