WELDING RODS, WELDING ELECTRODES BASIC INFO AND TUTORIALS

INFORMATION ABOUT WELDING RODS AND WELDING ELECTRODES
Welding Rods/ Electrodes Tutorials


A BASIC GUIDE OF ARC WELDING ELECTRODES
There are many different types of electrodes used in the shielded metal arc welding, (SMAW) process. The intent of this guide is to help with the identification and selection of these electrodes.
ELECTRODE IDENTIFICATION

Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16 to 5/16 . An example would be a welding rod identified as an 1/8" E6011 electrode.
The electrode is 1/8" in diameter

The "E" stands for arc welding electrode.

Next will be either a 4 or 5 digit number stamped on the electrode. The first two numbers of a 4 digit number and the first 3 digits of a 5 digit number indicate the minimum tensile strength (in thousands of pounds per square inch) of the weld that the rod will produce, stress relieved. Examples would be as follows:

E60xx would have a tensile strength of 60,000 psi E110XX would be 110,000 psi

The next to last digit indicates the position the electrode can be use in. READ MORE...

A QUICK REFERENCE FOR WELDING

All positions
Deep penetration
DC reverse polarity
Rod is mild steel
Application – use medium arc, whipping or weaving on vertical and overhead to control bead sag.

GAS WELDING RODS

Gas Welding Rods come in different forms such as, Aluminum, Bronze Alloy, Carbon Steel, Copper Alloy, Hard Facing and Maintenance Alloy. Manufacturers include ESAB, Harris Welco and Radnor. You'll find all of your gas welding rod needs with Airgas.Aluminum gas welding rod comes in two varieties, bare and flux-cored. Bare is recommended for brazing thin sheets, extruded shapes and especially corner joints. Flux-cored has non-corrosive, non-hygroscopic flux inside a tubular rod; no separate flux required.

Silicon Bronze is a copper based filler metal primarily used for TIG and oxyacetylene welding of copper, copper-silicon and copper-zinc base metals to themselves and to steel. Silicon bronze can be used for on plain or galvanized steel sheet metal. It can also be used for surfacing areas subjected to corrosion. READ MORE...

WHAT ARE WELDING RODS?

There are a lot of different welding electrodes and wires out there. In the field, welding electrodes are usually referred to as "welding rods" so I will use that term here.

"Stick Welding" is also the term of choice in the field for SMAW, the acronym for Shielded Metal Arc Welding.

Stick welding used to be done with a bare welding rod. It was very difficult, and could only be used in the flat position. If you've ever stuck a rod with flux on it, you can only imagine how many times they stuck bare rods! If the rod gets too close to the base metal it will decrease the voltage causing the arc to go out. READ MORE...
