ARC Welding

An arc strike in welding is a defect formed by an electric arc that melts the base metal. It creates discontinuities, such as localized remelted metal and changes in the surface profile. This process involves intense heating followed by rapid cooling, which can negatively impact weld quality. To repair an arc strike, the welder should … Read more

Arc stud welding provides strong, high-speed welds with ferrous and some non-ferrous metals. However, it has downsides. It encounters challenges with aluminum and brass due to their thermal properties and reactivity. These metals often require specialized electrodes or gas mixtures for effective welding. However, arc stud welding has its disadvantages. It requires skilled operatives to … Read more

To improve your stick welding skills, keep a steady arc length of about 3mm. Use the right amperage for your electrode to avoid sticking. Make sure your work clamp is secure and grounded. Practice different joint types and positions like flat, vertical, and overhead to master welding techniques. These tips will help beginners succeed in … Read more

Arc force in welding refers to the increased amperage at lower voltage. This feature boosts welding performance by enhancing penetration. You can adjust arc force to achieve a smooth weld puddle or improve digging power on challenging materials, such as during the root pass. It helps maintain stability throughout the welding process. When adjusting rod … Read more

Arc formation in welding happens when an electric arc forms between an electrode and the workpieces. This process uses electrical current to generate heat. The heat melts the metals, creating a strong connection known as a weld joint. Properly controlling the arc is crucial for effective and safe welding. In addition, the arc’s properties impact … Read more

Arc generation in welding happens when voltage rises between two electrodes. This voltage breaks down air insulation and lets current flow. The bright light and high heat produce an electric arc. This arc acts as the heat source for melting materials, making it essential to the welding process. The benefits of effective arc generation include … Read more

The term ‘arc’ in welding is not an acronym. It refers to arc welding, a process that joins metal parts using an electric arc. This arc is formed by an electrode, which creates electricity. The arc connects two metallic surfaces, melting them and causing them to fuse together. The processes involved in Electric Arc Welding … Read more

Arc blow occurs in DC arc welding. It happens when the arc stream does not follow the shortest path between the electrode and the workpiece. This deflection can move in various directions—forward, backward, or sideways. Knowing how arc blow affects the welding process is essential for ensuring good bead quality and overall results. Preventing arc … Read more

Arc blow in stud welding is the unwanted deflection of the welding arc. It mainly occurs in two forms: magnetic arc blow and thermal arc blow. This phenomenon causes the arc to deviate from the stud’s axis. Such deviation can lead to welding defects and reduce the quality of the weld. Preventing arc blow involves … Read more

An arc column in welding is the pathway of electric current between two electrodes in ionized gas. The negatively charged cathode and positively charged anode create intense heat. This heat speeds up the movement of negative ions and positive ions within the plasma column, making the welding process effective. Physics governs the arc column, as … Read more
