AWS : E 7016
BIS : EB 5426 H?3X
-
Characteristics :
A medium heavy coated, Basic type, Hydrogen controlled all Position electrode delivering a strong penetrating arc, Easily detachable slag. The weld resist cracking under severe restraint conditions and also suitable for welding in sub zero temperature condition Recommended for welding of MS, Low alloy and medium alloy -high tensil steel for depositingbuffer layer forhardfacting appliations, For joining MS to cast steels. Delivers very
good all-weld mechanical properties.
-
Applictions :
Welding rails to MS girders, Butt welding fo rail ends, For over-head cranes. For joining MS to cast Iron, MS plates having thickness more than 20 mm as a buffer layer prior to hard surfacing, Boilers repairs of ci Parts (with repuisite per - Heating for larger components)shipping vessels, Oil tanks, For Railways ClassIII steels etc.
