Welding Porosity  Porosity in welding is the presence of cavities in the weld metal caused by the solidification or “locking in” of gas pockets caused by impurities or contaminants in the molten weld pool.  This welding defect can lead to detrimental effects. In structural welded connections, porosity can reduce the load-bearing capacity of the weld joint. In pipe and vessel welds, porosity can lead to reduced strength, diminished pressure capacity, and even loss of containment.  The best way to eliminate this potentially catastrophic welding defect is to understand the causes o ..read more

Embarking on a welding project? Like any craftsman, a welder is only as good as their tools. And when it comes to choosing the right welding method, knowledge is your most powerful asset. Let’s delve into the fascinating world of MIG and TIG welding. We’ll explore their nuances, strengths, and weaknesses to help you make an informed decision. The World of MIG Welding What is MIG Welding? Metal Inert Gas welding (MIG) operates by feeding a continuous spool of welding wire that melts, fuses, and burns the base and parent materials. This method is incredibly versatile — perfectly handling variou ..read more

Stainless steel is a type of metal that is somewhat paradoxical in nature. It is exceptionally corrosion and abrasion-resistant, making it ideal for high-temperature applications. However, it also has a significantly slimmer margin of error and is less forgiving of mistakes made in welding operations. Because of this duality, it’s important to learn about the distinctive characteristics of stainless steel and the techniques required to achieve high-quality welds with this unique material.  Jump to a section: What is Stainless Steel | Welding Applications | Stainless Steel G ..read more

Welding is crucial in the construction industry, serving as a critical fabrication process in creating robust and secure structures. This process involves the fusion of materials, typically metals or thermoplastics, by utilizing high heat to melt the parts together. In the sphere of construction, welding finds its application in various tasks - from joining steel frames that form the skeleton of buildings to producing machinery and equipment essential for construction tasks. Materials, cost, efficiency, and safety are determining factors when choosing a welding method in the construction secto ..read more

The integrity of weld joints is vital in every application and industry. One common problem welders encounter that can compromise a weld’s quality is welding undercut. This defect, characterized by a groove or depression along the weld's edge, can weaken connections and promote corrosion. In this article, we delve into the essential techniques and strategies to prevent undercut in welding for seasoned welding professionals and beginners alike.  Jump to a section: Causes of Undercutting | Type of Undercut | How to Prevent Undercutting | Electrode & Shielding | Prevention Checks f ..read more
