ARC Welding

The arc in arc welding is an electrical current that generates high heat. This heat melts the base material and the electrode, joining two pieces of metal. The arc forms between the electrode and the base material, creating a strong weld. Knowing how the arc works is vital for successful welding. The process begins by … Read more

DC arc welding provides a stable arc with consistent current flow. It produces less spatter, leading to cleaner welds and easier cleanup. It also simplifies starting the arc and offers precise control. In comparison, AC arc welding is ideal for thicker materials but may have more spatter and lesser control. The pros of DC Arc … Read more

Arc welding is powered by electrical energy from two main types of power sources: constant current and constant voltage power supplies. Constant current supplies keep a steady current for the welding arc. Constant voltage supplies adjust the voltage based on the welding conditions. Both sources are crucial for reliable and efficient welding applications. Key characteristics … Read more

A flash burn, also called welder’s flash or arc eye, happens from intense ultraviolet (UV) light exposure from welding torches. This can damage the eyes, similar to sunburn. Symptoms include pain, redness, and light sensitivity. Using proper eye protection is essential to prevent this damage. Proper protective gear is essential to prevent these injuries. Welders … Read more

Arc welding is a process that joins metals using an electric arc between an electrode and the metal. The electricity generates heat that melts the metal. As it cools, the materials fuse together. This welding technique is widely used in industrial applications, such as construction and manufacturing, because it offers precision and strong bonds. Various … Read more

Shielded metal arc welding (SMAW), also known as manual metal arc welding, uses a consumable electrode. As the electrode melts, it creates a protective cover. This cover shields the weld area from oxygen and atmospheric gases. SMAW is popular due to its simplicity and versatility across different applications. To begin with SMAW, it’s essential to … Read more
