Understanding Acceptable Welding Undercut and Its Acceptance Criteria Welding undercut is a groove melted into the base metal adjacent to the weld toe that isn’t filled with weld metal. While some degree of undercut may seem minor, excessive or poorly formed undercut can reduce fatigue life, create stress risers, and …

How to Prevent Welding Rod Sticking Definition and Explanation Welding rod sticking occurs when the electrode fuses slightly to the workpiece without establishing a stable arc. Instead of a clean ignition, the rod stops conducting properly and becomes part of the base metal until you yank it free. Arc Initiation …

How NOT to Stick Weld Mastering stick welding (Shielded Metal Arc Welding or SMAW) is as much about knowing how NOT to Stick Weld as it is about following the right steps. Many welders, especially beginners, unknowingly form bad habits that limit their weld quality, cause frustration, or even lead to …

Understanding Blowholes in Welding: Causes, Prevention, and Inspection In the world of welding, we encounter various challenges. Welding isn’t just about melting metal; it’s about creating strong, reliable joints that meet specific standards. However, imperfections known as welding defects can arise, which may compromise the integrity, strength, and appearance of …

How to Avoid Cast Iron Cracking Why Cast Iron Cracks During Welding Welding cast iron is notoriously difficult due to its brittle nature and high carbon content. One of the biggest challenges welders face is cast iron cracking, which can occur before, during, or after welding. The primary culprit behind …

What is Anti-Spatter Spray? Does it Actually Work? Welding is an essential process in various industries, from automotive to construction. However, one of the most frustrating aspects of welding is dealing with spatter—those tiny molten metal droplets that stick to surfaces, causing defects and requiring extra cleanup. To combat this …

How to Deal With Weld Spatter In Stick Welding Welding can be an incredibly rewarding skill, but let’s face it—stick welding (also known as Shielded Metal Arc Welding or SMAW) can be messy. Spatter, those annoying metal droplets flying everywhere, can make an otherwise enjoyable job frustrating. But hey, don’t …

How NOT TO Weld | MIG Welding Mistakes Introduction MIG welding, or Metal Inert Gas welding, is a preferred method for joining metals due to its speed, efficiency, and ease of learning. Despite its popularity, MIG welding is susceptible to numerous common errors. These mistakes can result in weak welds, …

Common TIG Welding Problems and Their Solutions TIG welding, or Tungsten Inert Gas welding, is renowned for producing clean, precise, and high-quality welds. However, like any technical skill, it’s not without its challenges. In this article, we’ll dive into some common problems faced by TIG welders and explore practical solutions …

How to Prevent Arc Blow in Stick Welding Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a versatile and widely used welding process. However, it comes with its own set of challenges, one of which is arc blow. If you’ve ever experienced an erratic arc, spatter, or uneven …
