What is the Filler Wire?

Filler Wire offers forty grades of welding wire across three different material types since selecting the right filler metal for your project is just as critical as effectively executing the weld itself. This wide range of materials allows you to select the best material for your application and metal composition for solid connections. Take a time to read the following article before going to our welding wire products page if you’re just starting a project and aren’t sure which welding consumable to use, or if you’ve ever wondered what filler metal is.

Filler Wire, commonly known as welding wire, is a length of wire used to secure metal seams during the welding process. Filler metal comes in a range of shapes and sizes, including rods and reels, to fulfill the specific requirements of MIG, TIG, and SAW welding methods. A wire from reels is often used in MIG welding, whereas wire from rods is typically used in TIG welding. You must first determine which type of welding your application necessitates before selecting a specific material.

Uses of Filler Wire

Tungsten Electrodes

The tungsten electrodes used in welding are not intended to be utilized as filler rods in the technical sense. Tungsten is a hard metal with a high melting point (3,410°C/6,170°F), making it extremely heat resistant. These tungsten electrodes are available in a variety of sizes, but most are sold in 10-packs. They come in a variety of diameters and lengths, with the one you require depending on the standard tip that comes with your TIG torch. Electrodes made of pure tungsten or a hybrid of tungsten and other rare elements, oxides, and alloys are available, and the electrodes’ tips are color-coded for easy identification. Your electrode selection is also influenced by the material you’re working with, its thickness, and whether you’re using a wet or dry electrode.

Pure Tungsten Electrodes

This is a cost-effective choice made of 99.50 percent tungsten, but it has the highest consumption rate. When heated, pure tungsten forms a clean, balled tip and is commonly used for AC welding of Aluminium and magnesium at low currents. These electrodes are good for AC welding arc stability. It is not commonly used for DC welding because it lacks the powerful arc initiation that other hybrid electrodes, such as throated or created electrodes, give.
