Yes, voltage changes with varying arc length during welding. In a constant current (CC) setup, the welding current stays the same, but the voltage adjusts. A longer arc usually increases the voltage, while a shorter arc decreases it. Understanding this relationship is essential for achieving high-quality welds. The change in voltage impacts the current flowing … Read more

Carbon arc welding (CAW) uses a nonconsumable carbon electrode to form an electric arc. This arc produces high temperatures that melt base metals, enabling their coalescence. CAW is effective for welding copper and its alloys. It is also useful in air carbon arc gouging, which is a technique for cutting metals. The technique operates primarily … Read more

The working principle of an AC arc welding transformer is based on electromagnetic induction. When current flows through the primary coil, it creates a magnetic field. This magnetic field induces current in the secondary coil. The induced current generates heat, which is essential for the welding process. The working principle involves electromagnetic induction. An alternating … Read more

A weld pool in arc welding is the molten metal formed during the process. It occurs when the base metal reaches its melting point. The weld pool allows the addition of filler material. This area is vital for creating a strong bond between the metals. The quality of the weld depends on the success of … Read more

Submerged arc welding is an industrial process created in 1935 by the E. O. Paton Electric Welding Institute in Kyiv, Ukraine. This technique uses an electrical arc to join a workpiece and an electrode. It is important for many welding applications due to its efficiency and effectiveness. SAW’s historical significance lies in its advantages. It … Read more

Arc welding is a process that joins metal pieces using electric arcs to produce heat. This heat melts the metal, allowing it to fuse as it cools. Common techniques include stick, MIG, and TIG welding. Its applications are vast, ranging from construction to automotive manufacturing, highlighting its flexibility across industries. There are several types of … Read more

Exposure to welding arc rays can lead to serious injuries like photokeratitis, also known as “Welder’s eye.” Other risks include keratoconjunctivitis, cataracts, and retinal injuries. To avoid these effects, it is crucial to use protective measures, such as safety goggles or face shields, while working with welding equipment. To ensure safety while welding, specific safety … Read more
