The ANSI recommends shade numbers for arc welding based on the arc current. For Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW), use shade 11 for 60-160 amps, shade 12 for 160-250 amps, and shade 14 for 250-500 amps. For Gas Tungsten Arc Welding (GTAW), use shade 10 for under 50 amps. … Read more

The temperature of arc welding ranges from 5,000°C to 20,000°C. This high heat melts the base material and the electrode, allowing them to fuse. Iron melts at around 1,500°C. Maintaining the right temperature is crucial for ensuring strong welds and high welding quality. Moreover, external conditions like ambient temperature and ventilation impact the arc welding … Read more

The temperature of an electric welding arc can reach about 10,000 degrees Fahrenheit. This high heat makes arc welding effective for joining different metals. Although temperatures can vary based on the material, this intense heat promotes strong welds and improves the overall welding process. This high temperature allows metals to achieve a molten state. As … Read more

Arc welding is a fusion process that joins metals using intense heat. This heat melts the metal at the joint, allowing it to mix. A molten filler metal is often added. As it cools and solidifies, it creates a strong metallurgical bond. Cutting uses a similar heat method for processing metal. The processes of arc … Read more

A welding chart provides the recommended amperages for electrodes in stick welding. The amperage values depend on the electrode diameter: 1/8” (75-125A), 5/32” (110-190A), 3/16” (140-250A), and 7/32” (170-310A). Follow these guidelines to achieve optimal results when selecting electrode sizes. When working with thicker materials, higher amperage is necessary. Conversely, thinner metals require lower amperage … Read more

The arc length in welding, known as arc gap, measures the distance from the electrode tip to the workpiece. You can calculate it using the formula Arc Length = (θ/360°)(2πR). Aim for an arc length close to the electrode wire’s diameter for best results in GMAW or MIG welding. Maintain this distance for optimal heat … Read more

Arc flash burns, also known as corneal flash burns, usually heal with proper care. For treatment, rest your eyes, use lubricating and antibiotic eye drops, and apply cool packs. Avoid rubbing your eyes. Prevent burns by wearing protective eyewear like safety glasses or a welding helmet. Seek medical help if symptoms worsen. Home remedies can … Read more

Symptoms of welding arc flash include severe pain, bloodshot eyes, light sensitivity, excessive tearing, and blurry vision. People may also feel a gritty sensation in their eyes. These symptoms can develop hours after exposure. With proper eye rest and treatment, relief usually occurs within a few days. The primary cause of these symptoms is the … Read more

Always wear an auto-darkening welding helmet to protect against arc flash. Set up safe work zones with welding curtains. Use UV-filtering safety glasses for eye protection. Wear protective clothing, including a flameproof jacket and apron. Long-term UV exposure can lead to skin damage and increase the risk of skin cancer. To ensure welding arc flash … Read more

Welding arc flash intensity drops as you move away from the source. To lower injury risk, stay at least 10 meters away from the arc. Even short exposure close to the arc can cause harm. Always wear adequate protection when working nearby, and remember that maintaining distance is key to preventing injuries. Experts recommend keeping … Read more
