Welding Electrodes & Filler Metals

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

Shielded Metal Arc Welding Electrode Classification System

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

Tungsten Electrodes

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
