This category contains information about various kinds of electrodes, wires, fluxes, inserts used for welding in the industry.
The electrodes used in flux-cored arc welding are made up of a flux core, surrounded by a metal sheath. The primary function of flux at the core of the wire is to provide shielding to the arc from the oxidizing gases in the atmosphere such as oxygen and nitrogen. The metal sheath accounts for 75 … Read more
Welding consumables are an important part of welding. Having a quality electrode in hand is vital to the quality of joint to be made. In this article, we shall see some aspects of electrodes and filler rods used for welding. The most authoritative classification of welding consumables has been done by American Welding Society (AWS). … Read more
The classification system for SMAW electrodes is identical between AWS (American Welding Society) and ASME BPVC. In this article, we shall take reference from ASME BPVC Section II Part C for studying various electrode classification. The SMAW electrodes are classified under the following specifications in ASME Section II Part C. SFA 5.1: specification for carbon … Read more
The welding consumables in the welding process come in a variety of forms. For shielded metal arc welding, the filler comes in the form of a flux covered stick electrode. For flux-cored arc welding, it comes in the form of spooled wires that have flux at the core, and a metal sheath around it. In … Read more
When molten metal is exposed to air, it reacts with oxygen and nitrogen present in the air. As a result, metal oxides form which are detrimental to the integrity and strength of the weld. Hence, it is required to protect the molten metal from this oxidation. In covered electrodes, this protection is provided by the … Read more
Non-consumable tungsten electrodes for GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) welding, generally are of several types. Types Of Tungsten Electrodes Tungsten electrodes types and their typical application can be identified by color-coded end marks as follows. Pure Tungsten Electrodes Pure tungsten electrodes are generally used on less critical welding operations than the tungsten electrodes … Read more
