An extra low hydrogen low heat input electrode depositing a low steel weld metal. Extra high strength facilitates welding of critical jobs.
LoTherme-355 is an extra low hydrogen low heat input electrode depositing a low alloy steel, high strength weld metal ideal for maintenance and repair welding of Cr- Ni -Mo high strength low alloy steels, case hardened steels, heat-treated steels, etc. The extra low hydrogen helps in preventing cold cracks.
Ideal for maintenance and repair welding of high strength steels, case hardened steels, heat-treated steels, etc. Typical applications include welding of rolls, shafts, gear wheels, etc.
ULTIMATE TENSILE STRENGTH : 78 kgf/mm2
ELONGATION (L=4d) : 20 %
Redry the electrodes at 350°C for 2 hours. Clean the weld area free of all contaminants. In case of the case hardened materials, the case depth should be removed before welding. Depending on the base material, a suitable procedure should be evolved for reclamation.
