Constant current submerged arc welding (SAW) is an automated welding process. It uses a continuously fed electrode and provides stable arc performance. SAW achieves high penetration and operates within a current range of 50 to 2000 amperes. This efficiency makes it suitable for applications like tanks and pressure vessels while ensuring high weld quality. CCSAW … Read more

Arc welding, specifically MIG (Metal Inert Gas) welding, uses a consumable electrode to weld metals through an electric arc. MIG welding offers high efficiency and is ideal for thinner metals. Its portability and simplicity make it a popular choice for many applications. Gas shielding enhances the quality of the weld, distinguishing it from other techniques. … Read more

Electric arc welding includes key components: electrodes that carry electricity, a power supply for energy, and base metals that are joined. It also involves heat generation for melting metals and optional filler materials to strengthen the weld. Safety equipment is essential to protect the welder during the process. There are various electric arc welding processes, … Read more

Plasma Arc Welding (PAW) is a progressive method compared to TIG welding. It increases production speed and improves weld penetration. PAW efficiently welds medium thickness materials in a single pass without grooving. These advantages make PAW a cost-effective solution in modern manufacturing industries. However, plasma arc welding has limitations. The equipment can be expensive, making … Read more

Submerged Arc Welding (SAW) is a welding process known for its high efficiency. It excels in heavy-duty applications by creating high-quality, deep-penetration welds quickly. Industries favor SAW because it produces robust joints, making it ideal for projects that require strength and durability. The primary pros of Submerged Arc Welding include its ability to handle thick … Read more

Conjunctivitis UV welding arc, known as Arc Eye or Snow Blindness, happens due to too much ultraviolet (UV) light exposure. Symptoms show 6 to 12 hours after exposure and include red eyes, painful eyes, watery eyes, and light sensitivity. Common sources of UV light are welding and sun lamps. Immediate treatment typically involves flushing the … Read more

Shielded Metal Arc Welding (SMAW) requires key components: an arc welding power source, electrode lead cable, electrode holder, leads, cables, cable connectors, ground clamp, and chipping hammer. Each part contributes to safe and effective welding. Always prioritize the use of safety equipment during operations. Beginners should focus on understanding the various types of electrodes and … Read more

A suitable power supply for plasma arc welding is a direct-current (DC) source with a drooping characteristic. It should have an open circuit voltage of at least 70 volts. Rectifiers are preferred over DC generators. When using helium as an inert gas, the voltage requirement stays above 70 volts. The voltage also influences heat input, … Read more

DC carbon arc welding (CAW) uses one or two electrodes to create heat through an electric arc. It is similar to gas-tungsten arc welding (GTAW). The setup often operates on direct current (dc) with electrode negative. This process is popular for welding applications that need high precision and control. The primary technique in DC Carbon … Read more

Arc welding uses electric arcs and a power supply for welding. DC welding has benefits over AC welding, such as a stable arc, easier starts, and less spatter. This results in better weld quality. DC welding is ideal for difficult positions, like overhead, ensuring reliable and high-quality metal joining. Choosing between DC Welding and Arc … Read more
