The hardest part of the welding process isn’t the welding itself. It’s trying to weld while crammed into a vehicle’s engine compartment, an aircraft’s wing structure, or while dangling from rafters two stories above the shop floor. Awkward, uncomfortable, or inaccessible positions are a common part of welding. One of…
Gas tungsten arc welding (GTAW), also called tungsten inert gas (TIG), arc welding is one of the most precise and controllable types of welding there is. Of the common types of arc welding used on construction sites or in manufacturing plants, GTAW offers the cleanest welds by far. A great…
It isn’t uncommon for the wire in a wire feed arc welding machine to snag, melt back into the tip, and bring welding to a halt. The welder must then disassemble the machine to correct the problem. The culprit is usually the liner that guides the wire, which welders often…
Tungsten has the highest melting point of all metals at 3422° C (6192° F), has three times the density of steel, and is the favorite metal of those who want to punch large holes in objects. However, tungsten can also create as well as destroy, and these properties make it…
It often takes very little time for new welders to experience the detrimental health effects of welding. Flash-burned eyes are a familiar sensation to many welders in spite of precautions, and most welders know what it is like to work through metal fume fever to complete a shift. Although efforts…
An arc welding monitoring system is an essential tool in any shop that has a significant volume of orbital welding projects. Just as the mechanization of orbital welding procedures has enabled welders to boost productivity, weld vision systems make it possible for welders to improve the quality, efficiency, and safety…
If you’re wondering how to record a weld puddle, you’re not alone. Nearly every welder at some point in their career has had a compelling reason to record or review a recording of a welding procedure. Though nothing replaces hands-on experience, an apprentice welder can use a recording to observe…
