WELD
OVERLAY |
| Our weld overlay service is used
by customers in a number of industry sectors where service conditions
require corrosion resisting properties. Weld overlay often provides
cost and schedule advantages over solid corrosion resisting
alloys. |
|
| This means that we overlay a
diverse range of components in terms of geometries, base materials
and weld overlay grades, which are either 'free issued' by customers
or purchased by Arc Energy as semi-finished products. |
|
| Arc Energy also
offer a machining service for customers requiring proof or finished
machined items. |
