Precision At The Arc

Engineering Precision at the Arc with a GMAW Setup

In the world of metal fabrication, precision at the arc directly affects weld quality and structural integrity. Achieving it requires more than just skill. It demands a deep understanding of the gas metal arc welding (GMAW) gun and the adjacent componentry that can directly affect aspects of the weld, such as the weld pool size, joint penetration depth, and overall weld appearance. Maintaining arc control and consistency is a necessity, and the quality of a weld hinges on the seamless interaction of the gun setup, a welder’s experience, and thoughtful engineering.
