Classifications unalloyed
EN ISO 636-A: AWS A5.18:
W 42 5 W3Si1 ER70S-6
Characteristics and field of use
Universally applicable copper coated welding rod with a largely spatter-free material transfer.
The welding rod is suitable for joint welding in the construction of boilers， containers and building
structures.
B?HLER EMK 6 is also suitable for use in acid gas (HIC test according to NACE TM-02-84).
Values for the SSC test are also available.
