1885 saw the advent of resistance welding, and in 1893, oxyfuel welding and thermite welding established themselves. In 1881, two inventors working together, Stanislaw Olszewski and Nikolai Benardos created the first electrical arc weld using carbon electrodes.ĭuring the last decades of the 19th century and the first decades of the 20th century, a number of new welding methods were developed. The short-pulse electrical arc soon led to the continuous electrical arc, which is the basis for arc welding. The discovery of the short-pulse electrical arc in 1800 by Sir Humphry Davy, was the first step. It wasn't until the 19th century that welding began to modernize into the forms that are often employed today. In 1540, De la Pirotechnia, an in-depth book on metallurgy was published and it included a detailed section of the process of forging and forge welding. Throughout the Middle ages, people became incredibly skilled in forge welding and produced a number of impressive metal works. While it is not known exactly when welding made its first debut in human history, all accounts show that it is truly an ancient craft. It is also known that welding was used during construction of the Iron Pillar of Delhi, which took place in 310 CE. There is a written account from the 5th century BCE by Herodotus, an ancient Greek historian, that states Glaucus of Chios invented welding. Evidence of forge welding has been found dating all the way back to the bronze age. It is a process by which blacksmiths continuously pound red hot metal until it binds together. The earliest form of welding is known as forge welding. Welding should only be performed by trained welders to prevent personal injury or death. Welding involves using high voltages to melt metal which creates a risk of shock and burns. Thanks to auto-darkening helmets like the Lincoln Electric Twisted Metal, the 3M SpeedGlas 9100, and the Miller Electric 251292, this can be avoided. Then in the middle of the night, you wake up and feel like someone rubbed sand in your eyes. This exposed retinas to UV rays that would add up over the course of a work-day. Often, instead of following safety protocol, you would start the welding process and then flip your helmet down. The problem was that you had to place your welding hand(s) right at the workpiece, then manually flip your helmet down, then your welding hand would inevitably move and you would be forced to flip your helmet back up to reposition because you can't see anything through a standard welding lens until there is an arc. Before their advent, welders would typically go through a training period characterized by excruciating eye pain(many still do). It also features three auto-darkening view filters with six sensors, and a 3,000-hour battery life, making it an ideal choice for professionals.Īuto-darkening welding helmets have become absolutely essential for welding. Also included is the Yesweldes Panoramic, which boasts a 180-degree field of view thanks to its twin side windows, giving a total of three LCD Screens that can work both independently and synchronously. It features an auto-darkening, true color lens with a 3.64 by 1.67-inch viewing area, and when lifted a large clear screen allows other tasks to be completed while still providing necessary eye and skin protection. We included the Tooliom Clamshell in the list due to its unique, flip-up visor, which allows simple transition from welding tasks. Most of the helmets here feature auto-darkening screens, with the exception of the Honeywell Piperliner, which is a no-frills option that is notable for its compact size. In this update, we added several new helmets to the ranking with modern features and improved safety. They are suitable for a range of welding styles, most commonly MIG, TIG, and MMA, and in some cases plasma too. As the most essential item of personal protection a welder can have, a high-quality welding helmet, often referred to as a 'hood', not only protects the skin from sparks and burns, but it also protects the eyes from vision damaging ultraviolet and infrared rays that are emitted by the arc.
