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

High Hardness Alloy Steels

High Hardness Alloy Steels, include a large number and variety of high strength, high hardness, corrosion-resistant alloy steels, which have been developed with other special properties. Most of these steels depend on a special heat treatment process in order to develop the desired characteristic in the finished state. Alloy steels have greater strength and durability than other … Read more

Non-Consumable Electrodes and Other Filler Metals

Non-consumable electrodes are the ones that don’t get consumed during the welding process. An examples of such electrodes is the tungsten electrode used in the gas tungsten arc welding process. Another example is the carbon electrode used in the carbon arc welding process. In this article, we shall discuss in brief about these two non-consumable … Read more
