How to correctly grind Tungsten Electrode for TIG Welding

Grinding and preparing tungsten electrodes prior to welding is the key to a quality weld, stable arc, and uniform weld bead appearance. A wrong tungsten preparation for a welder can lead to shabby welds, wandering arc, and in-sufficient weld penetration.

This post guide the welders on how to prepare the tungsten for best welding outcomes. Before, let us see basic about Tungsten Electrode used in Welding.

TIG welding electrodes are made from Tungsten (either pure or by doping with other elements). The reason for using Tungsten is- it’s a high melting temperature of 3422°C (6192°F), thus is the best material for TIG electrodes that can give longer life.

The above melting temperature can be further increased by alloying the tungsten with other metals oxides (e.g. thorium oxide). This is called doping. Doping of tungsten electrodes increase its melting temperature, its electrical conductivity reduced electric resistance, and improves arc ignition properties compared to pure tungsten electrode.

Why it’s important to Grind/ Sharpen Tungsten Electrodes in TIG Welding?

The correct distribution of energy in the direction of the parts to be welded and the magnitude of the arc pressure depend on the shape of the tip, which, in turn, will determine the shape of the weld.

Therefore, sharpening must be approached seriously and competently. Sharpening can be carried out on an electric emery manually, but the best results are achieved using special devices, such as automatic tungsten grinders.

  • Pure Tungsten electrode must end with a ball;
  • Thoriated tungsten electrodes. the end of the electrode should have a slight bulge;
  • Other types are sharpened with a cone (like a pencil).

An interesting feature is observed when welding aluminum parts – a sphere is formed at the end of the electrode, and there is no need for sharpening. The length of the section to be sharpened is determined by the diameter of the bar multiplied by 2.5. This ratio is constant.

Details about various types of Tungsten electrodes used for TIG welding are given in AWS A5.12- SPECIFICATION FOR TUNGSTEN AND OXIDE DISPERSED TUNGSTEN ELECTRODES FOR ARC WELDING AND CUTTING.

The commonly used metal oxides for alloying of tungsten electrodes in TIG welding are: Thorium oxide (ThO2) Zirconium oxide (ZrO2) Lanthanum oxide (LaO2) Cerium oxide (CeO2)

Tungsten Electrodes dimensions sizes

Tungsten electrodes are available in different diameters from 0.010 inches to 0.250 (1⁄4) inches (0.5 to 8 mm) for TIG welding. The most frequently used dimensions for TIG welding electrodes are 3⁄32 inches (2.4 mm) and 1⁄8 inches (3.2 mm). The selection of electrode diameter is based on the welding current, material to be welded, and type of current (AC or DC).

Grind correctly Tungsten for TIG Welding

The most important condition for getting a good quality result of TIG welding is that the tungsten electrode point must be ground correctly to the shape. The angle of tungsten defines the shape of the weld pool- a small pointed rod angle will give a narrow weld pool while a rod with a bigger pointed angle will result in a wide weld pool.

For DCEN welding polarity, the tungsten electrode should have a conical shape as shown in the below figure. This shape gives a concentrated/ focused welding arc which in turn gives a narrow and deeper welding penetration. As a thumb rule, the length of the ground conical shape shall be twice the diameter of the tungsten electrode. Refer the below picture on the right-hand side for more details.

Miller Tungsten Grinder review

A Miller tungsten grinder is a tool used for grinding tungsten electrodes, which are used in the welding process.

The best way to grind Tungsten

Tungsten electrodes are made of tungsten, a hard and dense metal that is resistant to heat and wear. Miller tungsten grinders are specifically designed to grind tungsten electrodes to the precise shape and angle required for the welding process.

This ensures that the welding arc is stable and produces high-quality welds.

Miller is a brand of welding and cutting equipment, and their tungsten grinders are known for their durability and performance.

Best Miller Tungsten Grinder

If you are looking for a professional grade hand-held grinder in a compact size, then the Miller Tungsten Grinder is for you. It has all the features of other professional grade grinders in the market but it is not as bulky. The Miller Tungsten Grinder features a slim design, which makes it easier to operate by hand, compared to other grinders with similar features. Accessories are available for larger electrodes.

Miller grinder parts

The head of the grinder shows you all the options available. It has multiple ports for different thickness of electrodes. It can also grind in four pre-set angles, 15, 18, 22.5 and 30 degrees. Lastly, it has the option for creating a flat tip.

While most benchtop grinders require presetting preparations to work, the miller Weldcraft grinder is simple to use. It is as easy as turning it on and inserting the electrode into the right port. You will be able to see the node size and the grinding angle on the side of the head. Because the diamond wheel is used solely for tungsten grinding, your electrode will not be contaminated in the grinding process.

The Miller Tungsten Grinder, also known as Weldcraft Triad tungsten grinder, comes with many accessories to add more features. The first one is the cutting attachment, which allows the user to make accurate cuts in pre-set lengths. This is important if your applications need extremely short tungsten electrodes.

The Miller Tungsten Grinder can also be equipped with the double-decker grinding kit. This add-on to the head allows the user to do more grinding angles while adding only 0.4 lbs. This add-on is important if you are doing orbital TIG applications. It comes with its second wheel that expands your pre-set angle options. This negates the need for additional grinders when working away from your shop.

When working in your shop, you can also get the mounting accessory for the grinder. You can screw this mount to a table away from your welding area. Once screwed in place, you can insert the grinder into the hole of the mount so that it remains in place while grinding.

With the mount, you no longer need to hold the grinder while operating it. The vibrations of the tool will be passed on to the mount and into the table. If you need to use it away from your shop, you can just remove it from the mount.

Ease of use

The Miller Weldcraft grinder is easy to use and handle. With simple instructions, you can teach your staff around the shop how to use the Miller Tungsten Grinder. Even beginners can give you an accurate grind with this tool. You can trust them with this important task without worrying that they might grind the electrode sideways or waste too much of the electrode.

A tough lightweight tool

The primary reason for buying the Miller Tungsten Grinder is for its toughness. As a professional grade grinder, it will be able to handle tough working environments. Its toughness should be the norm in the hand-held tungsten grinder market. Even in the outdoors, the Miller Tungsten Grinder will give you accurately ground electrodes.

To protect it during transport, it comes with a steel case where you can place all the accessories that you need to bring with you. It will keep your grinder secure when you are done using it. It also ensures that the Miller Tungsten Grinder will last long even if you use it in different weather conditions.

Overall, the Miller grinder is one of the best in the business for long-term outdoor use. It is lightweight, so you can use it even in awkward positions. It gives you multiple preparation options while still giving you a clean and well-shaped tungsten electrode tip.
