When a craftsman needs to form an integral connection of various workpieces made of steel, titanium, stainless steel or other material, he necessarily uses argon welding, which differs from all analogues in its specificity. The unit combines all the features of an electric arc and gas product. In order for the work to go quickly and efficiently, you need to prepare filler rods for argon arc welding in advance.

Working principle

Quality melting of the edges of various parts to be joined and filler material, with which a small weld is formed, is achieved due to high temperatures resulting from the burning of an electric arc. Argon provides protective functions. Careful welding of non-ferrous metals and alloys, as well as alloy steels, has its own characteristics. During interaction with oxygen and other elements contained in the environment, active oxidation of metals occurs. This isthe circumstance is negatively reflected on the final quality of the formed seam, which turns out to be loose. To avoid all the negative points, experts recommend using filler rods for TIG welding.

Characteristic

Welding rod is presented in the form of a conventional metal wire or an artificial polymer, which is used by professionals to fill and form a strong seam. The length of the standard product is one meter. For comfortable operation, the rods are wound into reels. Products are ideal for fixing all types of metals. Classic filler rods for argon arc welding should match the composition of the base material with which to work. But this consumable is not suitable for stainless steel.

Operating Rules

TIG welding rods cannot be used without a torch. A special tungsten electrode with a projection of 5 mm is inserted into the central part of this unit. In the inner compartment, the product is fixed with a holder. For the timely supply of protective gas, the burner is equipped with a reliable ceramic nozzle. The seam is formed with a wire. For the processing of stainless steel workpieces, the filler rod for argon arc welding is selected especially responsibly so that the result meets all operational requirements. During operation, an electric arc is ignited. The electrode must not touch the surfaces to be joined. This rule ismust be respected as the ionization potential of argon is extremely high.

Varieties

Today there is no single classification of welding rods, as there are quite a few of them. The final choice depends on the type of material being processed. Aluminum filler rods for TIG welding are characterized by high performance. The resulting seams never crack. Aluminum bars have high thermal conductivity, which is highly valued in large-scale industries. Copper products are in the greatest demand. Numerous positive characteristics allow high-quality soldering of copper, regardless of the size of the part.
