But you can also view these appendages negatively. Although western people are distrustful of the E, it is however very popular among Europeans and Asians, especially, for purposes of doing a root pass welds. Moreover, Asians and Europeans seem to make the E their choice when it comes to root pass. The E appears to have its merit for it leaves behind a smooth inside root. After a bit of trial and error, you would surely discover that the E can be easily kept from overly reinforcing the root.

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.
