What Is Welding Bead And What Are Their Types? Comprehensive guide 2022

What Is a Welding Bead?

A welding bead is a deposit of stuffing metal from a single welding pass. In other words, a welder makes the first pass and then lifts the electrode out of the weld pool leaving behind only excess metal to be used for some projects or discarded entirely.

Welding can create an aesthetically pleasing finished look that also improves the integrity of the joint. The filler metal is pressed up against the joint and melted to form a cohesive bond.

This application of heat allows us to weld together materials that are normally impossible due to their difference in chemical makeup, property, or texture. 

Our welding beads come in a variety of sizes (you can check out our different options here) and colors, allowing you to personalize your project by choosing whichever one suits you best.

Why Use Different Torch Movements?

While the process of stitching a seam in cloth seems simple enough to those who have never tried doing it, it’s actually quite complicated when viewed under a microscope because you have to take into account the amount of force being used to push the needle through both layers of fabric at once as well as its size. 

In contrast, metal welders frequently perform in an embarrassing situation while not sporting safety glasses and sometimes actually gloves as part of their work since they have to wear heavy equipment for protection during this task.

The amount of gravity that plays into your final design is directly related to how you’re positioned relative to your four-foot welding table or equipment.

For example, imagine trying to operate that TIG torch from inside a coal mine – gravity alone is going to cause molten material dripping onto your head if you move too slowly.

Types Of Welding Beads & Torch Movements

When it comes to being a working welder, torch manipulation is pretty much the same when it comes to sticking welding with a separate filler rod and gas metal arc welding with a mechanically provided wire or rod electrode.

While there are some strategies and tips you can use especially on certain projects that require special attention to detail.

There are two main types of welding bead:

  • Stringer beads
  • Weave beads

Stringer Beads

A string bead is a straightforward method of welding where the welder moves back and forth with patterns that form an even line. Pulling and dragging are both methods of pushing, where the torch is aimed down at an angle so that the head stays behind the melting puddle, causing penetration.

Pushing and leaning away from the weld (which it must be done when working vertically) are both examples of this motion. As opposed to these methods, pushing involves moving backward or forwards while following the puddle; this leaves a string of added metal adjacent to the weld for added protection for areas susceptible to rusting or scratching.

Dragging the base metal into place is an excellent method for welding and a great way to do things, but in certain circumstances such as large welds or high production environments, pushing the metal into place tends to be more effective. 

This is accomplished by using a stringer welding bead, which while being very wide can almost be used anywhere you see fit. You’re still moving in one direction (a straight line) the only difference is that you have a longer piece of metal to work with that allows connections at both ends of the weld once it becomes one piece.

Sometimes, carrying the torch slowly sufficiently lets the weld puddle involve and protect both edges of the combined. This strategy may be all it brings to perform a suitable seal.

Further times, a little side-to-side motion is essential- as displayed in this picture on the left. Preserve any side-to-side activity minimal for acquiring a good seal or you’ll end up with something resembling a weaved bracelet which is called a “stringer bead” (illustrated in the image on the right.)

Welding Bead

Weave Beads

Different things work for different people. In the case of welding, some welders prefer to weave from side to side in order to create a wider weld, and others who tend to be more heavy-handed like to do a lot of weaving so they can build up the weld beads quickly. 

That’s why it’s important that you feel comfortable with your process and find one that is right for you specifically in which way best suits your expertise, but practice makes perfect when it comes down to weaves.

Another way that you can use weaving is to change things up for even heating; this, in turn, will prevent burning onto the metal. Additionally, you can halt briefly when moving from one side of a weld joint to the other so that you can tie everything together properly and prevent the metal from being undercut. 

Overall though, weaving is mainly used to help you get around joints more efficiently, as opposed to stick welding which tends to cover larger surfaces evenly but takes longer than welding in an S-pattern because of how much flux is necessary to get a nice looking bead.

A triangle weave is useful for filling in the hollows of a vertical weld when making strong materials such as steel. In vertical welding, this technique cements shelves behind the molten metal so that it won’t slide downwards.

 If you want to keep the tilting of your sheaf from getting too great, try a half-circle weave with your torch strokes on either side of the puddle. The more deeply into the puddle you enter with your blazing tool, the hotter it will be for greater solidity and stability.

Welding Beads

Types Of Welding Bead

1. TIG Welding Beads

The welding beads that are associated with TIG welding generally have a stacked-up effect because the welder is adding more filler metal and depositing it in even segments.

Given the popularity of TIG welding, there is some flexibility to experiment with the way in which fillers are added during a weld as long as it still provides an effective bead overall. 

The frequency and amount at which these steps are performed may need to change slightly depending on the size of the application or how thick of material will be used because thinner materials generally need more filler to achieve a durable finish.

TIG welds can be done with a very smooth flow, creating the “stack of dimes” effect. This is where the filler rod flows through the TIG gun and out into a nice smooth line.

But sometimes welding isn’t so easy and one must spend more time learning how to achieve this desired result, or maybe they’re not as skilled at it yet. So there’s another option – TIG Welders prefer doing what’s called “Walking The Cup”. 

This type of TIG welding beads technique is when the welder moves back and forth while simultaneously holding the electrode inside the cup, which allows them to spread filler metal along a wider axis – like spreading cream cheese across a bagel before it’s been toasted.

2. Stick Welding Beads

Stick welding beads come in different shapes and sizes. The low-hydrogen family is quite versatile as a 7018 stick with low hydrogen content can be drag and stringer welding beads, which are very common in flat and horizontal positions as well as overhead welding. When it comes to vertical welding it’s wiser to work with a weaved pattern. 

Working uphill on vertical joints, one can use their creativity and try out multiple weaves or patterns like the long 4×1 or the simple 2×2 twill using almost any kind of stick electrode you have at hand! 

This makes it a lot easier on hydrogen-free welding tests, but it takes some time to get used to this way of fabricating an even wall type or columnar welding bead at times when CWI gives us just enough time for one or two passes only – providing you don’t want to polish your entire joint after getting a Puddle Start Tack.

Welding steel with a stick rod is almost like sculpting – especially when one is familiar with the Miami freeze technique. As its name suggests, this welding style was born in Miami and for quite some time, it was viewed as a top-secret formula that welders would never reveal to anyone.

Using 7010 rods to make this kind of weld creates an open root, but the rod will still require some post-weld heat treatment just like it would if it was used on different metals.

This process involves putting INLAY coal in an arc furnace and heating the steel pipe or plate for about six hours at about 2500 degrees Fahrenheit (about 1150 celsius). 

The stick will nonetheless be ready for use after the said process has been completed as well as another post-weld heat treatment procedure which ranks at 1000 F (which is close enough to spray paint temperature… therefore it usually doesn’t harm the underlying coating).

3. Mig Welding Beads

Hardwire MIG is very versatile as there are a variety of techniques that can be used to create the best welds.

While pushing or pulling the puddle is not going to determine whether your weld is more likely to crack, those who do either one may prefer using a shield on the workpiece in order to help prevent oxidation and protect them from other hazards associated with it such as spatter or splashback. 

There have been instances where people choose to place an object beneath their workpiece so that it creates a seal between the work and the ground, however, if it’s situated too close in proximity to your project, you could end up radiating heat from your torch onto whatever material it has been placed beneath.

As stated previously regarding drag or pushing with stick or flux core MIG welding beads for this particular discursive frame, dragging does have its advantages when trying to precisely control localized penetration along edges of intricate designs where you want that unbroken look.

There are many techniques for weaving and the newer techniques found in the MIG like the TIG craze. It is important to know that even if you don’t need your weld for strength, it is worth making a flat, low-profile welding bead to ensure your end-user will be satisfied.

Another instance would be when welding beads with thicker metals, this technique allows you to have significantly better panel control.

The welding beads have become less formidable in nature because the low heat that is being used to fuse them goes through the sheet much less than a conventional torch.

However, their lighter appearance sparks a move towards their popularity in the off-road culture at large because they are so visually appealing on most parts of vehicles that are repaired in this fashion (especially when compared to other welds). 

4. Flux Cored MIG Welding Beads

Flux-cored welding wire is capable of depositing a large amount of filler metal in a given time. The vast majority of flux-cored wires are manufactured by simple stringers (these fillers make it possible for the flux-cored wire to offer stable shielding and high deposition rates).

We can use this property as an added advantage when it comes down to doing messy vertical-upward welding work; in such cases, we need to create a winding layer by doing so which will help us keep the molten puddle from spreading out too far and dripping off prematurely from the side of our workpiece.

Conclusion

There are different types of processes and potential welding applications for one, but what you need to remember is that it’s best to become proficient in three of them. MIG, TIG and Stick welding. Since people sometimes have different opinions about which one is the right process to go with, it is best practice to be able to do all three techniques. As you are really likely to need both worlds: a durable project and impressively fine perfections.
