Cobalt Alloy electrode in the process of welding, after the core is coated with the coating, if used for submerged arc automatic welding, electroslag welding, gas shielded welding, gas welding and other welding methods for filling metal, the melted coating A layer of slag is formed to compensate for the burning of the alloying elements, and the weld metal must be protected from the weld by the coating and slowly cooled to reduce the possibility of generating pores.
Cobalt Chrome Alloy electrode is a molten electrode for coating electrode arc welding, which is composed of a coating body and a welding core. The chamfer at the front end of the electrode has a chamfer of about 45°, which is for the purpose of arc ignition. There is a section of bare core at the end, which accounts for about 1/16 of the total length of the electrode, which facilitates the clamping of the welding tongs and facilitates electrical conduction.
The diameter of the cobalt alloy electrode is actually the diameter of the core. It is usually 2, 2. 5, 3. 2 or 3, 4, 5 or 6 mm, etc., commonly used is small 3. 2 small 4, small 5 three, the length "L" is generally between 250^-450 mm.
The mechanical properties of cobalt alloy electrodes catch up to even exceed the basic metals. Will reduce the interaction of molten metal and air. In the welding process, it has the following effects: improving the stability of arc combustion. Reducing agents (such as manganese, silicon, titanium, aluminum, etc.) need to be added to the electrode coating to directly affect the quality of the weld.
At the same time, this can improve the stability of the arc and protect the weld pool. Converting electrical energy into heat, the amount of dust generated during welding will also decrease. It plays the role of mechanical protection, metallurgical treatment and improvement of process performance. click cobaltalloy.net for further more information.
