Slag[ edit ] Why is it necessary to remove the slag? Multi-passing multiple electrodes to build up a single homogeneous weld bead needs the slag removed after each pass, otherwise the slag left would form a weak non-metallic layer in the weld. NDT examination of high-quality welds afterwards is often about looking for such pieces of included slag. Its cousin E is similar except that it is used with alternating current. Examples of a fill-freeze electrodes are the E, E, and E, all of which provide a compromise between fast welding speeds and all-position welding.

E is primarily used for making the root pass when welding pipe. E is a low-hydrogen electrode used for high quality X-ray welds. It can be used in all positions with either AC or DC current. E is also used when weld bead apeparance is a priority.

All the added statements need to be confirmed in published works before being included here as per WP:V. Pipe welds are typically done with a root pass and cap.
