ARC Welding

Welding arc flash is an eye injury caused by intense ultraviolet radiation during welding. It can burn the outer layers of the eye, leading to discomfort and potential vision loss. The injury often happens when people look at the welding arc without protective eyewear. Always wear proper eye protection to prevent arc flash injuries. Welding … Read more

In electric arc welding, reverse polarity (electrode-positive) improves deep penetration but raises the heat. Straight polarity (electrode-negative) results in a faster melt-off rate and higher deposition rate. The overall welding performance can change depending on the type of electrode covering used. The key differences between straight and reverse polarity lie in heat distribution and arc … Read more

Stick welding may not start an arc for several reasons. First, check the amperage settings; they should match your rod size. Ensure the welding surface is clean. Use the scratch start or tap start techniques to begin the arc. Lastly, remove any excess flux from the rod tip. If problems continue, seek help from a … Read more

Stick Welding Electrodes are essential for Arc Welding. They conduct electrical current to fuse metals together. These consumable electrodes include common alloys like 6010, 7018, and 9018, as well as stainless steel types 308, 309, and 316. Steel Supply, L.P. supplies various options for different welding applications. E6010 is often used for pipe welding and … Read more

TIG welding creates a stable electric arc for clean and precise welds. It uses a non-consumable tungsten electrode. In contrast, arc welding, known as stick welding, utilizes a consumable electrode that melts to serve as filler metal. Each method offers different levels of controllability and is suited for specific applications. One advantage of Stig welding … Read more

In welding, positive polarity (DCEP) increases penetration by directing heat into the base metal. Negative polarity (DCEN) results in a flatter weld. Stick welding usually uses positive polarity for most tasks, but the polarity choice can change based on the type of electrode used. On the other hand, in Stinger Negative Arc Welding, the electrode … Read more

To start your arc in stick welding, quickly tap the welding rod’s tip against the workpiece. This removes excess flux. Use a sharp wrist motion for momentary contact, then pull the rod away slightly. This technique effectively initiates the welding arc and prepares the workpiece for a strong weld. Troubleshooting arc-starting issues is also crucial … Read more

आर्क वेल्डिंग म्हणजे धातूचे तुकडे एकत्र जोडण्यासाठी इलेक्ट्रिक आर्कचा वापर करणे. या प्रक्रियेत एक इलेक्ट्रोड आणि धातूचा तुकडा असतो. आर्क वेल्डिंग औद्योगिक क्षेत्रात अनेक उपयोग आहेत. यामध्ये सुरक्षितता उपायांचे पालन करणे आवश्यक आहे. The process includes several steps. First, the welder prepares the metal surfaces by cleaning them. Then, they generate an electric arc, which … Read more

Plasma arc welding is a precise welding process. It uses a plasma torch to join metals. This technique is similar to Gas Tungsten Arc Welding (GTAW), or TIG welding. An electric arc forms between an electrode and the workpiece. This creates a focused heat source for effective welding in industrial applications. The process begins with … Read more

Minus arc length in welding results from using lower voltage. This creates a shorter arc from the electrode tip to the workpiece. A shorter arc reduces heat input and affects penetration and weld bead appearance. Welders can adjust arc length to control power and amperage settings, improving overall welding quality. Adjusting arc length is essential … Read more
