LB-52U (E7016) is an unsurpassed covered electrode
for melt-through root-pass welding, or onesided
root pass welding with penetration beads.
With LB-52U your welding will be easier and
faster, and you will have confidence in the quality
of your welds in any kind of pipe welding of mild
steel and 490MPa high tensile strength steel.
Described here are the characteristics that have
made LB-52U the best for one-sided pipe welding.

(1) EXCELLENT USABILITY IN ALL-POSITION
WELDING
LB-52U features a very stable arc and low spatter
over a wide range of welding currents. In particular,
it really shines in the melt-through root-pass
welding of horizontally fixed pipes due to the
smooth, glossy penetration beads that protrude on
the reverse side of the groove (Figure 1) and the
wider tolerance of the root opening — an advantage
in site welding.

(2) SUPERIOR CRACK RESISTANCE AND
MECHANICAL PROPERTIES
LB-52U offers superior crack resistibility due to a
lower amount of diffusible hydrogen in the weld
metal. In addition, it excels in mechanical properties,
particularly in impact strength at low temperatures
(Table 1). Therefore, it can be used for lowtemperature
applications as well as moderate hightemperature
applications.

(3) FIELD-PROVEN ELECTRODE IN WORLDWIDE
MARKETS
The outstanding usability of LB-52U in the meltthrough
root-pass welding of pipe joints has satisfied
users around the world. LB-52U has been popular
for a variety of piping jobs across Russia, Asia
and the pacific region. Particularly in Russia, LB-
52U, with its extraordinary reliability, has made a
great contribution to the construction of long, oil
and gas pipelines in freezing weather. Since 1982,
more than 33,000 metric tons of LB-52U have
been consumed in the construction of the Russian
pipelines (Figure 2).
