Welding electrodes Monolith R
product.uv
- intended for welding butt and corner joints of metals up to 20 mm thick in all spatial positions except vertical from top to bottom for electrodes with a diameter of 5.0 mm
- insensitive to the quality of edge preparation, the presence of rust and other surface contamination of the welded material
- vertical joints are welded from top to bottom (2 - 4 mm in diameter) with a short arc or butt.
product.sv
- excellent welding and technological properties ensure easy ignition and re-ignition of the arc, as well as soft and stable arc burning, reduced metal loss due to spattering, uniform coating melting, excellent weld metal formation and easy separation of the slag crust
- excellent appearance and ease of use in all positions.
Specially designed for in-plant and cross-country pipe welding as well as welding in the sphere of shipbuilding construction, welding of general structures, bridges. Suitable for root run welding of pipelines of strength grades up to API 5LX80, as well as for filler and cover layers application for pipelines of strength grades up to API 5LX56
