ARC Welding

Begin your journey in Shielded Metal Arc Welding (SMAW), or stick welding. This guide covers essential techniques, safety tips, and instructions. Learn to strike an electric arc, manage arc length, and select the correct electrode diameter. Use consumable electrodes and practice on scrap metal to gain confidence. Always wear a welding mask for safety. Start … Read more

Arc welding is a fusion process that joins metals by applying intense heat. This heat melts the metal at the joint, allowing the parts to intermix. A molten filler metal is often added to improve strength. This method is popular in construction and fabrication because of its versatility and effectiveness. In SMAW, a consumable electrode … Read more

Arc welding is a process that uses an electric arc between an electrode and a workpiece as a heat source. Shielded Metal Arc Welding (SMAW), also known as stick welding, employs a flux-coated electrode. Key steps involve striking the arc, moving the electrode to create a bead, and shaping the weld to ensure strong joints. … Read more

Basic arc welding techniques include Shielded Metal Arc Welding (SMAW), known as stick welding. This method uses an electric arc to melt metal between an electrode and the workpiece. Key techniques involve using the correct electrode angle and movement. Variations like MIG and TIG welding are available for different joint configurations. Begin with proper setup. … Read more

Arc Force, also known as “Dig” or “Arc Control,” improves welding performance. It activates during the welding process to enhance arc stability. When the welding machine detects a short circuit, it delivers a peak current to maintain the arc. This feature works continuously, unlike Hot Start, which activates only at ignition. Functions of Arc Force … Read more

Regularly inspect key components. Check cables and hoses for wear. Assess risks continuously. Perform preventive maintenance every three months. Verify coolant levels. Review the Owner’s Manual for instructions. Replace worn consumables. Ensure compliance with OSHA standards for safety. Use ground clamps as needed during operation. Verify the grounding connections as well. A proper ground connection … Read more

Arc eye, or welder’s flash, is a painful injury to the cornea from ultraviolet (UV) rays during welding. Symptoms include pain, burning, redness, and light sensitivity. Treatment focuses on rest and pain relief. The inflammation typically resolves within a few days, leading to full recovery without lasting effects. The primary cause of arc eyes is … Read more

Arc efficiency in welding refers to how well the process uses heat. It is the percentage of generated heat that is utilized, typically ranging from 20% to 85%. Common arc-welding processes are Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW), and Submerged Arc Welding (SAW), listed from lowest to highest efficiency. Thermal efficiency … Read more

Arc burn, also called ‘welder’s flash’ or ‘arc eye’, is an eye injury caused by UV light during welding. Symptoms look like sunburn in the eyes. The cornea can heal in two days, but untreated burns may cause infection. To prevent this, wearing protective eyewear is crucial. The primary causes of arc burn include inadequate … Read more

Arc blow in DC arc welding is the deflection of the arc stream away from the direct path between the electrode and the workpiece. This deflection can happen in various directions, leading to inconsistent heat and welding issues. Recognizing arc blow helps to enhance welding techniques and ensure better results. The effects of arc blow … Read more
