Description
GTAW rod for high integrity welds. The low Si-content renders this filler metal particularly also
for joint welds that are subjected to enamelling or galvanising.
Especially suited for root pass welding (approved at -50 °C)
BÖHLER EML 5 can be used in sour gas applications (HIC-Test acc. NACE TM-02-84) as well.
