Welders

Welders, also called welding machines, are essential welding equipment designed to combine two or more pieces of metal together. Welding creates a robust and permanent bond between metal parts, making it a crucial process in construction, manufacturing, automotive repair, and many other fields. A welder uses pressure, high-power electric current, or both to create a strong bond between metals or other thermoplastic materials. These machines provide the necessary electrical or heat energy required to complete the weld with higher efficiency than soldering or blazing techniques. Welders vary in size and complexity–from small portable welders to heavy-duty industrial welders for industrial tasks. In addition, welding machines are often supplied with welding kit with various components for effective and efficient operations with robust safety. 

Popular Types of Welders

Several types of welding processes and corresponding welding equipment are suited for different materials and applications. Some of the most common welder types include:

• Arc Welders – Also called stick welders, these welding machines are widely used for their versatility on various metals, including steel, stainless steel, and cast iron. Arc welding is one of the most typical welding processes that involve creating an electric arc between a consumable electrode (usually a coated metal rod) and the workpiece. 
• MIG (Metal Inert Gas) Welders – MIG welding uses a wire electrode continuously fed through a welding gun. A shielding gas, typically a mixture of argon and carbon dioxide, protects the wire from contamination. MIG welders are known for their speed and ease of use, especially suited for automotive and fabrication industries.
• TIG (Tungsten Inert Gas) Welders – TIG welding is a precise and clean process employing the non-consumable tungsten electrode to create an arc. A separate filler metal is added manually as needed. TIG welders are suitable for thin materials and produce high-quality welds. These machines are often used in industries such as aerospace and precision welding.
• Spot Welders – Spot welding is a resistance welding process for joining thin metal sheets. These welders are commonly used in the automotive industry for assembling sheet metal components. A spot welder applies localised heat and pressure to create a weld at specific points.
• Plasma Arc Welders – Plasma arc welding utilises a high-velocity jet of ionised gas (plasma) to melt the workpiece and a tungsten electrode to transfer the arc. It is used for welding materials that require precision and control, such as stainless steel and aluminium.
• Flux-Cored Arc Welders – Similar to MIG welding, flux-cored arc welding uses a continuous wire electrode, but it has a flux core providing its own shielding. This process is often used for welding in outdoor or windy conditions.
• Resistance Welders – Resistance welding includes various techniques like spot welding, seam welding, and projection welding. These methods use electrical resistance to create heat and join metals together. They are commonly used in manufacturing, automotive, and assembly lines.
