All-State®
No. 616 Special
Low Alloy Steel Electrode AC
or DC Reverse Polarity (Electrode +) All Position General
Characteristics All-State®
No. 616 eliminates underbead cracking on high tensile and free machining steels
which are usually
high in sulphur. This electrode avoids the use of stainless steel electrodes in
many applications, thus doing
away with costly and time consuming operations. The specially formulated coating
helps to produce a quiet arc
with very little spatter loss. Specially designed for out-of-position welding.
Weld deposits are easily cut with an
oxygen/fuel torch. Typical
Applications Joining
high sulphur steels, low alloy steels, enamelling steels and cold rolled steels.
Recommended for maintenance
work where better physical properties than those yielded by mild steel electrodes
are required. Qualities
Tensile strength—up to 80,000
psi (56.26 kgs/mm2) Yield
strength—up to 70,000 psi (49.23 kgs/mm2)
Elongation in 2"—30 to 34%
Procedures Clean
weld area. Preheating is not required except on some highly hardenable steels
to prevent hard spots at the
fusion zone. Hold a short arc but do not whip as this may cause porosity. Stringer
beads are recommended. Weave
beads may be used but not more than two times the diameter of the electrode. When
using the larger sizes of
electrodes, a drag technique is suggested. Slag can be easily removed by chipping.
