Description:
Cromarod Duplex LP is a fully positional rutile flux coated electrode designed specially for
pipe-welding. It has a thin coating and fast-frezing slag, making it ideal for root runs. The electrode is
intended for welding similar composition duplex stainless steels, e.g. 1.4462, UNS 31803. With
thicker walled pipe it can be advantageous to use Cromarod Duplex LP for the root plus first passes
and then continue with ordinary Cromarod Duplex.
