Characteristics and field of use

Joint welding of matching base materials, as Material-No. 2.4819 (NiMo16Cr15W) and

surfacing on low-alloyed steels. It is employed primarily for welding components in plants

for chemical processes with highly corrosive media, but also for surfacing press tools,

punches etc. which operate at high temperatures.

In addition to its exceptional resistance to contaminated mineral acids, chlorine-contaminated

media, and chloride containing media, it resists strong oxidisers such as ferric and

cupric chlorides and is one of the few materials which will resist wet chlorine gas.

The stick electrode can be welded in all positions except vertical-down. Stable arc, easy slag

removal.

Welding instruction

For avoidance of intermetallic precipitation the stick electrode should be welded with lowest

possible heat input and minimum interpass temperature. Beam width of the prepared seam

approx. 70&deg;, root gap approx. 2 mm. Weld stick electrode with slight tilt and with a short

arc. String beads are welded. The interpass temperature of 150 &deg;C and a max. weaving

width 2,5 x diameter of the stick electrode core wire should not be exceeded. Re-dry the

stick electrodes 2 – 3 hours at 250 – 300 &deg;C before use and weld them out of a warm stick

electrode carrier.
