Welding electrodes IND Basic

AWS A5.1: E7018 H8

EN ISO 2560-A-E 42 4 B 4 2 H10

designed for welding in all spatial positions, except from vertical up, of critical structures and pipelines made of carbon and low-alloy steels with a tensile strength of 500 MPA to 640 MPA, especially if it is necessary to ensure high resistance of welded joints to hot cracks.

Special properties

the special coating prevents moisture absorption, reduces the possibility of pore formation and guarantees a low hydrogen content in the seam
smooth current-voltage characteristic provides a stable arc during the operation
excellent weldability, easy separation of slag crust, low metal loss from spattering
the electrodes do not absorb moisture from the environment for 10...12 hours after opening the package
due to this, they do not need to be re-dried before use, and are also characterized by high strength of the weld metal, with special metallurgical purity and low hydrogen content in the deposited metal
deposition rate factor: 0,16 – 0,18 g/А·min
electrodes consumption per 1 kg of deposited metal: 1,3 – 1,4 kg

IND Basic electrodes are designed for welding critical metal structures, boilers and tanks operating under high pressure. They are also used in pipeline construction, shipbuilding, etc. The electrodes are resistant to moisture absorption.
