How Electric Welding Works?

Electric Welding Works

Electric welding, or arc welding, is commonly used in construction sites, manufacturing plants, repairs or maintenance workshops, and even in our homes. However, the operation is a mystery for those new to the welding world. That’s why we will delve into the workings of electric welding in this blog. By the end of it, you’ll know how it works, what tools you need to get started, and how to perform some basic electric welding.

Understanding Electric Welding

Electric welding is a fusion welding process that generates heat from an electric arc between the workpiece and the welding electrode. As the arc melts, the electrode and the workpiece fuse and create a solid joint upon cooling. This process often uses alternating (AC) or direct (DC) power sources.

Essential Equipment Needed for Electric Welding

The essential tools required for electric welding include a welding machine, electrode holder, welding electrodes, ground clamp, and safety gear such as gloves, helmets, and fire-resistant clothing. The welding machine is the power source and generates the electric current that creates the arc. The electrode holder holds the welding electrode and is connected to the welding machine using a cable. The welding electrodes are the filler material used to bond the two workpieces together, and the ground clamp is used to connect the workpiece to the welding machine.

Different Types of Electric Welding

There are several types of electric welding techniques, including shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). SMAW, or stick welding, is the most common welding type and ideal for thick metal. GMAW, also known as MIG welding, is preferred for thin metals and is faster than SMAW. FCAW, on the other hand, uses a continuous wire electrode with a flux in the centre, making it ideal for outdoor use.

Tips for Safe Electric Welding

Electric welding requires the utmost safety and precaution. For starters, working in a well-ventilated area is advisable to avoid fumes from the welding process. Also, wear safety gear such as welding gloves, helmets, and protective clothing. Also, ensure that all electrical connections are secure before welding. In an emergency while welding, switch off the welding machine immediately and use a fire extinguisher to extinguish any fires.


Electric welding can seem complex for beginners, but you can start your electric welding journey with the right equipment, safety gear, and guidance. Always work in a safe environment, follow safety protocols, and practice your welding skills to perfect your technique. Whether joining metal pieces or creating metal crafts, electric welding is an excellent technique to master.
