The History of Metalworking
It has been pointed out that without fire, there would be no metalworking (nor metallurgy). It takes fire to heat metal so that it is malleable. It takes fire to heat ore so that metal can be extracted. Without fire, gold jewelry might be mankind’s only experience...
Metallurgy and Modern Metalworking
Metal may not make the world go ‘round, but it does make the world modern, in the most basic sense. Metal started out as esoteric substances hidden away in rocks. Once the properties of metals became known, those rocks became ore. The rest, as they say, is history....
The Importance of Shielding Gases
It’s all about integrity – not the welder’s, the weld’s. If you want a weld that is structurally sound – both now and in the long run – you want to implement a welding process that is gas-shielded. The weld pool or puddle is, during its creation, a very malleable and...
Argon-CO2 Welding
Argon and Carbon Dioxide are a match made in welding heaven. Argon is non-flammable and makes the ideal shielding gas for shielded arc welding. For aluminum, it is ideal all by itself, but for steel, carbon dioxide comes to its aid. The gas blend is shared at various...
