Description?G
The C-76
is the most widely used low hydrogen type electrode for
all position welding of 50 kgf/mm2 class high tensile
steel.X-ray performance and mechanical properties of
weld metal are excellent. The us abilities such as arc
smoothness, slag removal and bead appearance are good
and easy to weld in all position.
Application?G
Welding of 50 kgf/mm2
class high tensile steel in ships, bridges, buildings
and pressure vessels.
