EnDOtec DO*02 Flux-cored wire electrode

EnDOtec DO*02

The fully austenitic weld metal of the slag-free flux-cored wire electrode is rust-resistant, work-hardening and has a high elongation. Scale-resistant up to 850 °C. The lowest permissible operating temperature is –80 °C. Highest permissible operating temperature: 300 °C.

Applications
For dissimilar jointing of stainless austenitic steels, e.g.:
1.4301 - X 5 CrNi 18-10 (X 5 CrNi 18-9),
1.4308 - GX 6 CrNi 18-9,
1.4401 - X 5 CrNiMo 17-12-2 (X 5 CrNiMo 18-10),
1.4408 - GX 6 CrNiMo 18-10,
1.4435 - X 2 CrNiMo 18-14-3 (X 2 CrNiMo 18-12),
1.4436 - X 5 CrNiMo 17-13-3 (X 5 CrNiMo 18-12),
1.4541 - X 6 CrNiTi 18-10,
1.4550 - X 6 CrNiNb 18-10 (X 10 CrNiNb 18-9),
1.4571 - X 6 CrNiMoTi 17-12-2,
1.4573 - X 10 CrNiMoTi 18-12,
1.4580 - GX 10 CrNiMoNb 18-10,
1.4581 - GX 5 CrNiMoNb 18-10,
1.4583 - X 10 CrNiMoNb 18-12
with unalloyed and low-alloy steels such as:
P 265 GH, S 255 N to P 460 NL 2
and corresponding cast steel. Also for welding hardfacing and buffer layers on hardenable steels.

Processing instructions
Remove cracked and otherwise defective material. Clean the welding area. Weld using the short-circuit, spray or pulsed arc process, with preference given to the pulsed arc technique. Limit the interpass temperature to 150 °C. Use wire brushes made of austenitic CrNi steels. A plastic liner and contact tip, as for welding aluminium, are recommended.
