Welding of Welders All about Welding and Welders

What is Metallization: Process, Methods and Applications Metallization is the process of coating or bonding a thin layer of metal onto the surface of a non-metallic or metallic substrate. The primary purpose is to enhance physical properties such as electrical conductivity, corrosion resistance, wear resistance, and aesthetics. Whether it’s for …

How Much Porosity Is Acceptable in a Weld? Porosity is like the tiny potholes of the welding world — small, hidden, and sometimes harmless, but in the wrong spot or quantity, they can cause catastrophic failure. So, how much porosity is too much? The answer isn’t a one-size-fits-all — it …

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. …

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, …

Welding Electrodes Comparison: E6010 vs E6011 vs E6013 Importance of Choosing the Right Electrode In the world of Shielded Metal Arc Welding (SMAW), commonly known as stick welding, the choice of electrode can make or break the job—literally. Each electrode type is engineered for specific characteristics: deep or shallow penetration, …

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 …
