When the master needs to form an integral connection of various workpieces made of steel, titanium, stainless steel or other material, he always uses argon welding, which differs from all analogues in its specificity. The unit combines all the features of an electric arc and gas product. For the work to go quickly and efficiently, it is necessary to prepare filler rods for argon arc welding in advance.
Principle of operation
High-quality melting of the edges of various parts to be joined and filler material, with the help of which a small weld is formed, is achieved due to the 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 that are contained in the environment, the active oxidation of metals occurs. This circumstance is negatively displayed on the final quality of the formed seam, which is loose. To avoid all the negative aspects, experts recommend using filler rods for argon-arc welding.
Characteristic
The welding rod is presented in the form of a conventional metal wire or an artificial polymer, which is used by professionals to add and form a durable seam. The standard product is one meter long. For comfortable operation, the rods are wound into reels. Products are ideal for fixing all types of metals. The classic filler rods for argon-arc welding must match in composition with the basic material with which to work. But such a consumable is not designed for stainless steel.
Terms of Use
Filler rods for argon arc welding 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 by the holder. For timely supply of protective gas, the burner is equipped with a reliable ceramic nozzle. The seam is formed using wire. For machining stainless steel blanks, the filler rod for argon-arc welding is selected especially responsibly so that the result meets all operational requirements. During operation, the electric arc ignites. The electrode must not touch the mating surfaces. This rule must be observed, since the ionization potential of argon is extremely high.
Varieties
Today there is no single classification of welding rods, since there are quite a lot of them. The final choice depends on the type of material being processed. Welding rods for argon arc welding of aluminum are distinguished by high performance characteristics. Received seams never crack. Aluminum rods have high thermal conductivity, which is highly appreciated in large industries. Copper products are in greatest demand. Numerous positive characteristics allow high-quality soldering of copper, regardless of the size of the part.
