ARC Welding

The main types of electric welding arcs are: Gas Metal Arc Welding (GMAW), which uses a continuous wire feed; Gas Tungsten Arc Welding (GTAW), known for precision; Shielded Metal Arc Welding (SMAW), which employs consumable electrodes; and Flux-Cored Arc Welding (FCAW), which utilizes a tubular wire filled with flux. The most common type is the … Read more

Arc welding emits three types of light: visible light, ultraviolet light (UV), and infrared light (IR). These lights can harm the eyes and skin. UV light can cause serious eye damage, while infrared light can burn the skin. To protect yourself, always wear appropriate protective gear while welding. The benefits of light arc welding include … Read more

There are four types of flux used in submerged arc welding: fused fluxes, bonded fluxes, agglomerated fluxes, and mechanically mixed fluxes. Fused fluxes are made by melting materials in a high-temperature electric furnace, then cooling and grinding them to the right particle size for effective welding. Granular flux consists of a mixture of various materials, … Read more

In DC arc welding, there are three main types of polarity: Direct Current Straight Polarity, where electrons flow from the electrode to the workpiece; Direct Current Reverse Polarity, where the flow is reversed; and Alternating Current Polarity, which alternates the current direction. Each type affects welding penetration and heat. The choice of polarity affects the … Read more

The typical open-circuit voltage for electric arc welding machines depends on the current type. For DC welding, the range is 30 to 35 volts. For AC welding, it is usually between 50 and 90 volts. These voltages are essential for maintaining a stable and controlled arc during the welding process. Several key factors influence the … Read more

Each type has unique applications and benefits. SMAW uses a consumable electrode, which generates an … Read more

Ultrasonic vibration-assisted plasma arc welding boosts keyholing capability. The tungsten electrode sends ultrasonic vibration to the plasma arc. This interaction improves heat pressure and raises current density. Studies show enhanced molten metal flow and better welding efficiency, highlighting the advantages of ultrasonic support in welding processes. Ultrasonic vibrations can reduce porosity and improve penetration depth. … Read more

The American Welding Society (AWS) lists five main types of arc welding joints. These include: Butt joint, where two pieces meet end to end; Lap joint, which overlaps two pieces; Edge joint, connecting two edges; Tee joint, where one piece is perpendicular to another; and Corner joint, which connects two pieces at a right angle. … Read more

Arc welding includes five basic joint types defined by the American Welding Society (AWS). These are: Butt joint, for connecting two pieces end-to-end; Tee joint, where two pieces meet at a right angle; Corner joint, fitting together at a corner; Lap joint, with overlapping pieces; and Edge joint, aligning two edges. A butt joint connects … Read more
