ARC Welding

Arc eye, also known as photokeratitis, is a corneal injury like sunburn. It happens from unprotected exposure to ultraviolet (UV) rays from welding torches or similar sources. Symptoms include redness and eye pain. Wearing proper eye protection, such as goggles, is crucial to prevent this injury. Treatment often involves resting the eyes and using lubricating … Read more

Variable Polarity Plasma Arc Welding (VPPAW) is an AC welding method. It is designed for effective welding of lightweight alloys. VPPAW offers high efficiency and a low defect rate compared to traditional techniques. This process utilizes principles from Variable Polarity Tungsten Inert Gas (VP-TIG) welding. In advanced manufacturing, the ability to customize welding parameters is … Read more

Electric arc welding started in the late 19th century. Sir Humphry Davy produced the first electrical arc in 1800. In 1881, Nikolai Benardos and Stanisław Olszewski developed carbon arc welding. This technique became crucial for shipbuilding during World War II, highlighting major advancements in welding technology. By the 1900s, the introduction of coated electrodes improved … Read more

Welding arc flash protection is vital for preventing eye burns and skin injuries. Use welding helmets for UV protection and shield from debris.

Arc voltage in welding refers to the voltage across the welding arc. It is mostly determined by the arc length, which is the distance from the molten weld pool to the filler wire. In Gas Metal Arc Welding (GMAW), arc voltage is affected by current, arc length, shielding gas, and electrode extension. These factors influence … Read more

Welding parameters for arc welding include current, arc length, angle, manipulation speed, and amperage. Current affects the size and penetration of the weld. Arc length measures the gap between the electrode and workpieces. Adjusting these parameters helps improve the quality and efficiency of the weld. The second important parameter is the arc length. An optimal … Read more

Arc time in welding is the time the welding arc is active during a weld. This duration directly impacts production efficiency. It measures only welding time, not including part fit-up, material preparation, or post-weld processes. Understanding arc time allows you to optimize processes and enhance overall output. Effective management of arc time leads to increased … Read more

Air carbon arc gouging is a metal removal process. It uses heat from a carbon arc and compressed air to melt and remove metal from a workpiece. This efficient method needs a carbon/graphite electrode and operates at a minimum of 80 PSI. It is portable and effective for various applications. Applications of Air Arc Welding … Read more

Welding arc flash is an eye injury caused by intense ultraviolet radiation emitted during welding. It burns the outer layers of the eyeball. This often happens when people look directly at the welding arc without wearing protective eye gear. Symptoms include pain, light sensitivity, and changes in vision. Prevention is essential in industrial settings. Safety … Read more
