Flux-Cored Arc Welding: Self-Shielded vs Gas-Shielded Welding is at the core of modern metal fabrication, making it possible to construct bridges, ships, skyscrapers, and pipelines. Among the numerous welding methods available today, Flux-Cored Arc Welding (FCAW) has carved a niche for itself, especially in heavy industrial sectors. This semi-automatic or …

Designing Welded Joints: Types, Symbols, and Best Practices Welding is the backbone of modern metal fabrication, enabling the creation of strong, permanent joints in everything from pipelines to skyscrapers. However, the strength and integrity of a welded assembly aren’t just determined by the welder’s skill—it begins with smart joint design. …

ASME Section IX Quiz Welcome to our ASME Section IX sample quiz — your go-to resource for brushing up on welding and brazing qualification standards. Whether you’re an industry professional aiming to deepen your expertise, a student gearing up for certification exams, or simply curious about your welding knowledge, these …

Does Electrode Choice Matter? 6010 vs 7018 When performing Shielded Metal Arc Welding (SMAW) — more commonly known as stick welding — selecting the right electrode isn’t just a matter of preference; it’s a critical factor that can make or break your weld. Among the vast variety of electrodes available, …

Weld Bead Size and Deposition Rate Welding might look like sparks and smoke to the untrained eye, but behind every strong weld lies a balance of science, skill, and control. Two key factors—weld bead size and deposition rate—play an outsized role in determining not only the appearance of a weld …

Overhead Position Welding: Techniques, Challenges, and Best Practices What Is Overhead Position Welding? Overhead position welding is a challenging welding technique where the workpiece is located above the welder, and the weld is performed from the underside of the joint. Unlike flat or horizontal welding, the molten metal must be …

What Is a Seal Weld? What Is a Seal Weld? A seal weld is a type of weld applied primarily to prevent the passage of fluids, gases, or contaminants—not to provide structural strength. Unlike load-bearing welds, its role is sealing gaps or joints to prevent leaks, improve corrosion resistance, and …

What Is Duty Cycle in Welding? In welding operations, one technical specification that plays a crucial role in equipment performance is the duty cycle. Despite its importance, this parameter is often misunderstood or overlooked, leading to improper equipment use and reduced productivity. Why Duty Cycle Matters in Welding The duty …

How to Set MIG Welding Amperage and Wire Feed Speed Metal Inert Gas (MIG) welding is a cornerstone in fabrication, manufacturing, and repair industries. Its efficiency and relative ease of learning make it popular, but achieving consistently high-quality welds hinges on understanding and controlling its core parameters. Among the most …

What is 6GR Welding Position? Welding positions are classifications that describe the angle and orientation of the welded parts during the weld.The 6GR welding position is one of the most advanced and difficult positions out there. It’s used to simulate real-life situations where space is tight, movement is limited, and …
