Welding of Welders All about Welding and Welders

Welding Stainless to Carbon Steel Welding stainless steels to carbon (mild) steels is one of the most practical — yet metallurgically tricky — tasks a welder faces. The join is common in piping, heat exchangers, exhaust systems, and many retrofit repairs where corrosion resistance is needed only on one side …

Porosity vs. Blowholes — A Complete Practical Guide for Welders and Inspectors Porosity and blowholes are two of the most common gas-related discontinuities you’ll encounter in welding and casting. On the surface they can look similar—small pits, cavities, or irregular hollows in the weld—but their origins, shapes, consequences, and fixes …

In that case, you already know “welder qualification ranges” are the heart of getting people legally and safely onto the job. This guide unpacks how thickness, positions, …

VORITO VR-B12HD Auto Darkening Welding Helmet Introduction Welding helmets have come a long way from the old passive shades that required welders to nod their heads before striking an arc. Today’s auto-darkening welding helmets (ADWHs) are smarter, safer, and much more comfortable to use. Among them, the VORITO VR-B12HD Auto …

MIG Settings by Thickness (MIG Settings Chart & Tuning Guide) Getting MIG (GMAW) settings right begins with metal thickness. Thickness determines the transfer mode you can use, the wire size you should load, the gas you should choose, and—ultimately—the voltage and wire feed speed (WFS) that give sound fusion without …

What Is Hot Cracking (Solidification Cracking)? Quick Definition and Why It Matters Hot cracking—also called solidification cracking—is a weld defect that forms while the weld metal is still hot and partly solid, when weak liquid films at grain boundaries cannot accommodate shrinkage and tensile strains, causing the solidifying weld to …

Carbon Steel Welding Electrodes – A Complete Guide When it comes to welding carbon steel, the choice of electrode can make the difference between a flawless weld and one riddled with defects. Carbon steel is the most widely used steel type in manufacturing, construction, and repair because of its strength, …

Welding Copper and Brass Welding copper and brass isn’t like welding your typical mild steel. These two non-ferrous metals bring unique benefits—and their own set of challenges—to the fabrication table. From decorative metalwork to complex industrial systems, copper and brass are utilized in areas where conductivity, corrosion resistance, and aesthetics …
