The electrodes used for flux cored welding are almost visually the same as a MIG welding electrode. The difference is that flux cored electrodes are tubular, or a hollow tube with flux in the center. MIG welding electrodes are solid metal.
Flux cored electrodes come in standard sizes. Some are the same size as most MIG welding electrodes but others are comparable to the thickness of a stick welding electrode. Here are some of the more popular sizes for standard industrial applications:.035 .045 .052 1/16
As with most electrodes there is a standard classification code or designation code, on the spool they come on. To understand the classifications better it is important to know some basics about where the classification codes are different.
A somewhat common flux cored welding electrode is the “E71T – 1”. As with all electrodes the numbers and letters all mean something. There identifications are as follows.
E – Stands for electrode.
7 – Stands for the minimum amount of tensile strength. In this case it is 70,000 lbs of tensile strength per square inch of weld. The way this number is figured is by adding four zeros to the number.
1– Stands for the position that this electrode can be welded in. There are only two designations and they are “0” for flat and horizontal welding, then there is “1” for all position welding.
T – Stands for a tubular electrode. When “T” is used it is always assumed it is a flux cored electrode.
1 – The last is the shielding flux type designations.
As a note with all flux cored electrodes they need to be stored in a dry place. Otherwise the may pick up moisture and this will cause major weld defects.
