Corten Steel Welding Rods 3.2mm - E6818-W2 4kg Pack
If you want to read what the manufacturer says then read below but if you want the overview then this bit is for you. A E8018-W2 rod is a low hydrogen MMA rod that is designed specifically for weathering steels such as Corten.
Because of the above if you get these rods damp and require to rebake them then it does require a higher heat for a slightly longer than normal time. 300 to 350 degrees C for 2 hours.
This low alloyed high strength electrode is suitable for welding structural steels exposed to weathering conditions, especially COR-TEN. High mechanical properties with excellent crack resistance.
Features and Applications
- Content of Ni-Cu-Cr alloy
- Suitable for use in welding structural steels exposed to weathering, especially for COR-TEN B type steels.
- High mechanical properties with excellent crack resistance
- Convenience of welding at all positions except for vertical down position
- Weld deposits with very low contents of hydrogen
- Requirement of re-drying for minimum 2 hours at the temperatures between of 300°C and 350°C
