Description
Cellulose electrode for vertical-down welding of large diameter pipelines; suitable for root runs,
hot passes, filler and cover layers. Especially recommended for root run welding. Highly economical
compared with vertical-up welding. Apart from its excellent welding and gap bridging
characteristics FOX CEL offers a weld deposit with outstanding impact strength values and thus
offers the benefit of still more safety in field welding of pipelines. It can be used in sour gas
applications (HIC-Test acc. NACE TM-02-84). Test values for SSC-test are available too.
