For Stick Welding, recommended amperages depend on electrode diameter. For 1/8” electrodes, use 75-125 A. For 5/32”, use 110-170 A. For 3/16”, use 140-215 A. For 7/32”, use 170-250 A. Adjust the settings according to the specific needs of your weld to achieve the best results. Select the appropriate electrode based on the material and … Read more

The 3G welding position, or vertical position, involves welding a workpiece upright. The weld joint runs vertically. For example, you might use the 3G position when joining pipes in a vertical plane. This technique is important for creating strong welds and ensures high-quality results. Proper technique is essential. To achieve welding success, the welder should … Read more

Arc welding eye pain, called flash burn or welder’s flash, is like a sunburn to the eye. It affects both eyes and causes symptoms like redness and discomfort. The cornea usually heals in one to two days. If untreated, it can cause infection. Always wear protective eyewear to prevent this painful condition. Treatment for arc … Read more

To weld cast iron to steel, use flux-cored wire with an 80/20 argon-carbon dioxide shielding gas. Preheat the cast iron to 500-1200°F, depending on the material thickness, to reduce cracking. This technique secures a strong joint while limiting damage to both metals. Preheating the cast iron is an essential step. A temperature range of 400°F … Read more

Arc welding electrodes, like E7018, follow specific standards. The “E” denotes an electrode. The first two numbers indicate the minimum tensile strength in thousands of psi, meaning E7018 has a strength of 70,000 psi. AWS standards outline key specifications. Common stick rod diameters are 1/16”, 3/32”, 1/8”, and 5/32”. Arc welding electrodes are classified based … Read more

An arc welding equipment diagram shows the parts of a shielded metal arc welding machine. Key components include the power source, wire feeder, and electrode. This welding technique uses an electrically charged rod to create an arc and join two metal pieces. Always wear safety gear and have a fire extinguisher nearby. In addition to … Read more

Arc welding electrode numbers start with the letter “E.” In a 4-digit number, the first two digits show the minimum tensile strength in thousands of psi. In a 5-digit number, the first three digits represent the same. For example, E6010 means a tensile strength of 60,000 psi, while E10018 indicates 100,000 psi. Electrode sizes vary … Read more

To select an arc welding electrode, consider the base metal composition and strength. Match the electrode, such as E6010 or E7018, to the metal type and welding position. Evaluate electrode size, welding current, and surface cleanliness. Use ER308 or ER316 for stainless steel, and ER4043 or ER5356 for aluminum. The primary factors to consider when … Read more

Arc welding electrode coating material includes mineral silicates, oxides, fluorides, carbonates, hydrocarbons, and powdered metal alloys mixed with a liquid binder. This mixture is extruded onto a core wire. After extrusion, the electrodes undergo a drying process in ovens to complete their production. Selecting the right electrode coating material is vital for optimal performance. Factors … Read more
