When welding Corten the precautions are similar to mild steel except that you may need
a special filler material to produce the weathering steel weld. (6013s are not acceptable.)
- If the plate is 10mm thick or less, and the weld is a single pass (eg a fillet weld),
you can use an E7018 or SG2 MIG wire. This is because you will get enough dilution
from the plate to render the weld weathering. - If it's greater than 10mm thick or a multi-pass weld you need to use a filler containing
approximately 1% Nickel and 0.5% Copper (otherwise mild steel), or one containing
2.5% Nickel (otherwise mild steel).
This will result in a weld which will "weather" like the plate.
E 8018-C1, E 8018NiCuCr are also recommended for welding Corten steels.
Hence it is easy to make WPS

Subject: [MW:22930] SUITABLE ELECTRODE FOR S355 J2W CORTEN STEEL
Dear Experts,
-- We need to qualify a PQR for S355 J2W Corten Steel Plates and I request you to suggest a suitable electrode and provide me a PWPS for S355 J2W.
Thanks in advance.
Sincerely,
Vijay
