Designed for welding in all spatial positions, low hydrogen basic electrode, particularly suitable for critical applications, responsible structures and pipelines made of carbon and low-alloy steels with a strength limit from 550 (80) - 610 (88) MPa (ksi) requiring exceptional impacts at low temperatures, especially if it is necessary to ensure high resistance of welded joints against cold cracks. This electrode provides a smooth, stable arc with very low spatter. A special graphite tip on the electrode enhances excellent arc starting. The complete slag coverage provides easy removal and minimal post weld cleanup. It complies with the 4 mL/100 g requirement for diffusible hydrogen content in deposited weld metal. Additionally, it is vacuum-packaged to maintain extremely low moisture levels, eliminating the need for expensive re-baking processes.
Special properties
special coating prevents moisture absorption, reduces the likelihood of pores and guarantees a low hydrogen content in the joint
due to the uniform composition of the electrode coating at work a stable arc is achieved
excellent weldability, easy separation of the slag crust, low loss of metal from spattering
electrodes do not absorb the moisture from the environment for 10-12 hours after opening the package, thanks to this, they do not require rebaking before use
distinguished by the high strength of the metal joint with a special metalurgical purity and low content of hydrogen in the deposited metal
Monolith 7018-1 H4R is designed to be suitable for a broad range of carbon, low alloy, and hardenable steels. It is used for welding of responsible metal structures, boilers and tanks that work under high pressure, as well as in the construction of pipelines, low temperature structural work, in shipbuilding, petrochemical, pressure vessels, power generation. Electrodes are resistant to moisture absorption
Electrodes MONOLITH RC are differed from similar products of other manufacturers by a value and intensity of welding aerosol evolution and manganese formation during the welding process. This was achieved by selecting the high-quality raw materials and high-level control of technological processes in electrodes manufacture. The E.O. Paton Electric Welding Institute of the NAS Ukraine and Institution of Medicine Labour of the AMS Ukraine confirmed that manganese precipitation was reduced for more than 30%, the evolution of harmful elements in welding aerosol was reduced for more than 28%.
Electrodes MONOLITH RC are characterized by an easy primary and secondary arc exciting, soft and stable arc burning, provide low spatter loss, uniform melting of the coating, excellent weld metal formation, easy slag crust removal.
Electrodes allow welding at the lowest currents. For the small-diameter electrodes, the welding can be performed from power sources, connected to conventional mains.
Easy use of electrodes gives an opportunity to perform welding by a beginning welder.
Welding in hard-to-reach places. Feasibility of electrode bending without the coating damage.
It is possible to perform welding on oxidized, greased and painted surfaces.
