Welding Beads & Types of Welding Beads – TIG/MIG/STICK

Just like an artist takes various colors to create a painting. Similarly, a welder can establish a sound weld by using different and unique bead patterns. How about opting for the right welding bead to get done with this task?

Such beads allow the insertion of the filler materials between the two surfaces. Hence, they assist in forming strong bonds, which is the prerequisite of the welding procedure.

The common processes of welding are (TIG, MIG, and Stick). These processes require different welding beads.

This article reveals all the information about what a welder needs to do in any welding task.

 A fine welding beads pattern certainly solves all the problems associated with welding.

Types of Welding Beads

There are various types of welding beads depending on how extensive the vibration is during welding.

By this process, the filler material is applied to the surface. However, when the welder uses fewer vibrations, a narrow bead is formed, known as a stringer bead.

Weld Bead Size

The weld bead size comprises the height and width of the weld. These two features represent the quality of the weld and help us to get minimum flaws.

Additionally, weld bead size can be altered by welding current and traveling arc speed.

The width and height of the bead increase together.

TIG Welding Beads

TIG welding beads bear a “stack of coins” type of look. Since TIG is an arc welding process, it was developed to weld aluminum and magnesium alloys.

The process requires several dabs for adding filler material. These dabs add to the circular appearance of these beads.

The bigger the amount of dabs, the better is the circular shape. This step highly influences the resultant weld.

As you know, TIG welding is not that simple; you should keep in mind a lot of things that can go wrong. Be prepared to control the electrode with one hand, the rod with the other, all while adjusting the amperage.

After the bead comes to an end, you have to make few adjustments to get it right. To get the most attractive appearance of a TIG weld is making little alterations just as you finish the bead.

TIG welding is the most decent process of a weld, and thus our welding process gets no spark. It is beneficial for you to increase the speed of filling to get much finer beads.

MIG Welding Beads

 MIG welding beads are universal as there are so many techniques for establishing a good weld. Some welders prefer to push the puddle, and some pull the puddle. Though, there isn’t any hard and fast rule to follow.

If you are a welder, then you don’t need to drag your puddle. However, It is recommended to analyze and ensure the presence of slag before dragging. If you push a stick rod MIG gun in maximum cases, the probability of slag trapping in the weld becomes higher. This consequence is enhanced porosity.

With flux-coated welding techniques, the dragging approach accelerates the slag to form and stiffen at the back of your puddle as you continue the welding process.

Most of the MIG welders don’t like to weave or use any welding beads pattern. They will completely create an upright bead with the aid of a stinger. Although this can produce a sound weld, using a weave as a welding beads pattern can benefit wider joints and straight welds. It scatters the filler metal out more, resulting in a fine bead.

MIG like TIG technique

A new trending thing in the welding process is the “MIG like TIG” technique. Now, you can get your  MIG weld bead to look like the TIG dimes. It involves specific strategies with a low wire speed. These beads aren’t as harsh because the intense heat penetrates the metal a lot less than normal.

Not to mention, they have turned out to be a standard in the off-roading culture because of the clean and fine-looking welds (especially on car and vehicle parts). This technique can be fun too.

Flux Cored Beads

Flux core MIG can deposit a bunch of filler in a short period. Most of the flux-cored beads are run by simple electrode holders(stringers). Vertical Flux-cored welds will usually need a weave to regulate the puddle.

Weaving a flux-cored bead will save you from getting a “drip.” Eventually, when the weld gets too hot, and the molten metal drips off your piece of material onto the floor.

Stick Welding Beads

There are numerous bead characteristics in stick welding. The low hydrogen family of rods is quite versatile. We can use a common hydrogen type of rods which includes a low hydrogen rod. Use these beads effortlessly to draw a straight bead.

 Moreover, these beads are much narrower than others. Weave type pattern is preferred in vertical welding. Thus, the welder can use many different patterns to spread the filler material on the alloy surfaces.

In stick welding beads, we can also go for some cellulose stick rods. 6010s and 7010s. These must be used with proper technique. It appears like a penny. The ending result leads you to a much similar appearance as that of a TIG weld. Although, these welds are not as impressive as TIG welds.

Moreover, with this technique, the welder is proficient in striking an arc while holding the rod in position to make a coin-like shape.
