Welding & Fabricating S355J2+N Coil
S355J2+N welds by all common arc processes. A few points our buyers ask about:
| Matching filler | E7018 / ER70S-6 |
|---|---|
| Over-alloyed filler | Preheat thick sections |
| Preheat | As required by the WPS and code for the thickness |
| Cutting | Thermal or abrasive cutting; grind off heat-tinted edges before welding |
Follow your approved WPS; this is general guidance.
