ARC Welding

Welding fumes are harmful particles made of metals, metallic oxides, silicates, and fluorides. They form during metal arc welding when heated metal vaporizes and then condenses. Exposure to these fumes may cause health risks. Therefore, proper ventilation and safety precautions are crucial in workplaces that involve welding activities. To control exposure, it is essential to … Read more

Pulsed arc welding is a non-contact welding method. It uses arcs between a tungsten electrode and the workpiece for joint creation. This technique produces high-quality welds and creates a minimal heat affected zone. It does not require applied force for alignment, ensuring precise formation of joints. The benefits of pulsed arc welding include improved weld … Read more

There are several types of arc welding machines. They include stick welding, also known as Shielded Metal Arc Welding (SMAW), MIG welding (Gas Metal Arc Welding, GMAW), TIG welding (Gas Tungsten Arc Welding, GTAW), Flux-Cored Arc Welding (FCAW), Submerged Arc Welding (SAW), and Plasma Arc Welding (PAW). Each type has unique uses in various industries. … Read more

Manual metal arc welding (MMA), or stick welding, uses an electric arc between a coated metal rod (electrode) and the work piece. The flux coating on the electrode generates heat. This heat melts the electrode and the work piece, creating a strong weld when cooled. MMA is versatile and commonly used for metal joining. MMA … Read more

There are five main electric arc welding processes: Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), Flux-Cored Arc Welding (FCAW), and Submerged Arc Welding (SAW). Each process has unique characteristics and various applications in industries, providing flexible welding solutions. SMAW, also known as stick welding, utilizes a consumable … Read more

Common defects in arc welding include cracks, slag inclusions, porosity, and undercut. These defects can reduce the strength of the weld. To repair them, you can grind or chip away the damaged area and reweld using proper techniques. Understanding these issues is essential for achieving strong and reliable welds. Porosity: Air bubbles become trapped within … Read more
