ER 347 is made of heat-resistant high-alloy steel, resistant to corrosion and other. Aggressive factors of the environment, it has high strength. Doping of Mo, Si fine-grained eliminates corrosion and enables a high quality weld.
Surfacing difficult to weld steels — an integral part of any steel production, by means of which combine a variety of steel structures. This wire is used for semi-automatic and TIG welding austenitic-manganese corrosion-resistant grades with high tensile strength, high carbon and dissimilar steels, working at t ° to 300 ° C. Used for welding semi-automatic monoblock with a separate mechanism, the feed wire and 2 block. It is used for welding containers, piping in chemical and oil industry, food industry, mechanical engineering, is possible when using a carbon electrode metal, which leads to a significant decrease in weld quality.
There are 3 types of welding wire. 1) Activated wire (metal in its structure and 5% of powdered additives); 2) Solid wire — welding and semi-automatic rifles, 3) cored wire — s refractory metals for non-consumable electrode. Welding materials are divided according to the method of isolation, a number of modifications, and others. Qualities such as physical characteristics. By plasticity wire is divided into the 1st and 2nd class. Depending on the method of treatment — on the bright and oxidized. Last — is less common. If the damage of the wire is not recommended its use — it can it reduces the quality of the weld.
