How the Welding Wire Affects the Quality of a Weld

welder is working in the construction siteGas metal arc welding (GMAW), also called Metal Inert Gas (MIG) welding, is a popular welding process that melts and joins metals by forming an electric arc between consumable wire electrodes. The welding gun used for welding produces a protective gas that shields the entire process from contaminants in the air, ensuring a tight and smooth finish.

Understanding Welding

Developed in the 1940s, MIG welding was commonly used for welding aluminium and other non-ferrous materials. Soon, experts used it on steels because of the quick welding time compared to more traditional welding processes. The process was improved during the 1950s to the 1960s, giving MIG welding more versatility. Today, it is one of the most common industrial welding processes, revered for its speed and ease of usage for robotic automation.

In welding, it can take just one wrong move to put the quality of the outcome in jeopardy. Many factors can affect the weld, such as lack of fusion, cracking, improper penetration, porosity and undercuts. But, one often overlooked aspect of welding could be your key to success: your welding wires.

Better Wires for a Streamlined Process

High-quality MIG welding wires are essential elements in GMAW. They are responsible for forming the electric arc that melts your metal. When you choose the right wire, you reduce the need for pre-welding operations and cut the entire welding process short. The accuracy and consistency of the wire placement also minimises (or eliminates) the need for rework.

When choosing your welding wires, go for ones that boast top-notch toughness, superior feedability and cold-cracking resistance. Wires made from alloy, stainless steel, aluminium and silicone bronze are the common options when opting for high-quality wires. They make the welding process faster and provide excellent results.
