Welding electrodes Monolith 7016-1

AWS A5.1: E7016-1 H8
CSA W48:E4916
EN ISO 2560-A-E 42 5 B 2 2 H10
Terms of use

Welding should be carried out with direct current of reverse polarity (+) on the electrode, without preheating and subsequent heat treatment only on a short arc length along the cleaned edges.

Special properties
  • are characterized by high resistance of the seam metal to pores formation during arc extension, as well as by root seam welding with large gap of heavy wall pipes
  • short-arc welding with prior cleaning of edges is recommended
These electrodes are designed for welding of boiler heating surfaces elements, as well as root welding, joint welding of heavy wall pipelines made of carbon and low-alloy silicon-manganese steels with a tensile strength of at least 490 (70) MPa (ksi), operating at temperatures of up to 400°C (752°F).
