The method of metal processing (connection, cut) using manual electric arc welding involves the use of electrodes. Their great variety and difference in the principle of use still cause difficulties in choosing even for experienced specialists. A professionally developed online catalog of electrodes on the official website of their supplier to the domestic market can greatly facilitate this task. And we will tell you about the method of their classification in more detail.
Main views
Manufacturers of electrodes for manual electric arc welding take into account various options for their use and, in order to increase the competitiveness of their own products, modify them for work with certain types of alloys or non-ferrous metals, with a certain quality of the joint or increased cut accuracy. But, first of all, the buyer should take into account the fact that all produced electrodes can be divided into 2 main types:
- Consumable bar - made from raw cast iron, unalloyed steel or copper, depending on the material of use. They act as a cathode, anode or filler material, and can have a special coating. It is also manufactured taking into account the material to be welded. It contributes to stable retention of the arc, performs the functions of deoxidation and alloying of the metal being processed.
- With a non-consumable rod - refractory materials (tungsten, graphite) are used for manufacturing. When using them, filling the joints is carried out by manual filing of the filler material.
You can study the specific technical characteristics and capabilities of a particular model of electrodes using a detailed description in the catalog of the store selling them, in which they are sold at manufacturer's selling prices.
