Cobalt Chrome Alloy electrode classification.
According to different situations, there are three classification methods for cobalt alloy electrodes: classification according to the use of welding rods, classification according to the main chemical components of the coatings, and classification according to the characteristics of the slag after melting of the coatings.
According to the use of welding rods, cobalt alloy welding rods can be divided into: structural steel welding rods, heat-resistant steel welding rods, stainless steel welding rods, surfacing welding rods, low-temperature steel welding rods, cast iron welding rods, nickel and nickel alloy welding rods, copper and copper alloy welding rods, aluminum and Aluminum alloy electrode and special purpose electrode.
If classified according to the main chemical composition of the electrode coating, the Cobalt Alloy electrode can be divided into: titanium oxide electrode, titanium oxide calcium electrode, ilmenite electrode, iron oxide electrode, cellulose electrode, low hydrogen type. Welding rods, graphite electrodes and salt-based electrodes.
If the characteristics of the slag are classified according to the characteristics of the slag after melting, the Cobalt Alloy Plate electrode can be divided into an acid electrode and a basic electrode. The main component of the acid electrode coating is an acidic oxide such as silica, titania, or ferric oxide. The main component of the alkaline electrode coating is an alkaline oxide such as marble or fluorite.
- The electrode type is divided according to the mechanical properties of the deposited metal, the type of coating, the welding position and the type of welding current.
- The electrode type is compiled as follows: the letter “E” indicates the electrode; the first two digits indicate the minimum tensile strength of the deposited metal; the third digit indicates the welding position of the electrode. “0” and “1” indicate that the welding is applicable to all Position welding (flat, vertical, vertical, horizontal), “2” means that the welding rod is suitable for flat welding and flat welding, “4” means that the welding rod is suitable for downward vertical welding; when the third and fourth digits are combined, it means welding Current type and type of coating. After the fourth digit, “R” is attached to indicate that the moisture-absorbing electrode is attached; “M” is added to indicate that the electrode is resistant to moisture absorption and mechanical properties; and “-1” is added to indicate that the impact performance has special specifications.
