ARC Welding

For arc welding exceeding 400 amperes, use a shade lens number between 13 and 14. This range effectively protects the welder’s eyes from intense light and harmful radiation. Choosing the correct shade lens is essential to prevent eye damage and comply with safety standards for safe working conditions. Using a lens that is too light … Read more

An arc welding rod chart shows different welding rods for mild steel. It includes rod types, such as E6010 and E7018, their required amperage, and their applications. This chart helps users select the right rod by considering metal thickness and penetration levels, ensuring strong welds and proper techniques for successful welding projects. Common types include … Read more

The arc length in welding is the distance from the end of the stick electrode to the molten weld puddle. Proper arc length is crucial for effective welding. As the electrode wears down, monitor its distance from the weld puddle. Adjust the electrode position regularly to maintain optimal arc length for a high-quality weld. Weld … Read more

Arc welding is a metal joining technique. It uses an electric arc from an AC or DC power supply to generate intense heat, melting metal at up to 6,500°F. This process fuses the edges of two work pieces, forming a strong bond. Arc welding is common in construction and manufacturing projects. The benefit of arc … Read more

AC welding offers less penetration depth, making it suitable for thin materials and reducing heat. In contrast, DC welding provides deeper penetration, ideal for thicker materials needing strong welds. Select AC for lightweight applications and DC when higher weld strength and material thickness are necessary. Pros of AC welding include versatility and the ability to … Read more

Arc blow is a problem in DC arc welding. It happens when the arc stream moves away from the straight line between the electrode and the workpiece. This deviation can occur in any direction—forward, backward, or sideways. Recognizing arc blow is key to enhancing welding quality and preventing defects. To prevent arc blow, welders should … Read more

Arc welding is a method that joins materials using heat from an electric arc. For beginners, Shielded Metal Arc Welding (SMAW) is a great choice because it needs less equipment. Important tips include practicing welding safety, handling electrodes properly, and learning techniques for strong, effective welds. Moreover, safety is paramount in arc welding. Proper protective … Read more

Electric arc welding joins metals using an electric arc to generate intense heat. The arc forms at the electrode tip when current passes through a gap to the grounded metal. This process causes localized fusion of the parent and filler materials. Refer to the diagram for a clear view of the electric arc welding components. … Read more

Drawn arc stud welding is a process that uses a weld gun to place a stud on base metal. An electric solenoid raises the stud to a set height, creating a drawn arc. This arc melts the stud and base metal, forming a molten pool. The result is a precise and secure attachment, ideal for … Read more

The minimum protective shade for arc welding depends on the arc current. For Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW): use shade 7 for less than 60 amps, shade 10 for 60-160 amps, and shade 11 for 160-500 amps. Follow these guidelines to ensure safety and meet OSHA standards. For instance, … Read more
