| Description
and Applications |
| Pipestar
60 is all position, including vertical down, cellulosic electrode
for |
| high strength
pipe steels. It is recommended for vertical down welding of |
| large diameter
pipes API grades X46, X52, X56, and for root pass of |
| higher
grade pipes. |
| Distinguished
by its outstanding welding characteristics such as excellent |
| out of position
weldability, good striking and re striking properties, deep |
| penetration,
stabile arc, easy slag removal and X-ray quality joints and low |
| susceptibility
to wagon tracks, pinholes. |
