Electrodes come in 2 differing kinds. They are either consumable or non-consumable depending on if the electrode is really used up in the welding process or is able to be reused. These are just a few facts about arc welding.
The welding area is typically guarded by some form of inert gas. This is known as shielding. In the early days of arc welding, the shielding gases were oxygen and nitrogen. They tended to be crisp and porous and tended to fail. In the middle of the last century, research proved that hydrogen worked far better.
The welding industry is extraordinarily fond of the employment of initials in describing the various welding processes. MIG and TIG welding is a fine example. MIG welding means metal inactive gas welding and TIG welding is tungsten inert gas welding. Other common expressions are SAW for submerged arc welding and FCAW for flux-cored arc welding. The truth is that welding, although a particularly highly skilled craft, isn"t that hard to master. This is an important fact about arc welding because there is a dreadful deficit of qualified welders and the demand is growing every day. It was recently reported that the average age of the pro welder was a particularly high 54 years. It is easy to see that this rather old work force will be reaching retirement age in high numbers over the following a decade. This has led straight to the arc welding field being called one of the finest kept systems in the future work picture.
Due to the use of high voltage electric currents and unusually high temperatures, arc welding has traditionally been viewed as rather dangerous occupation. The risk from burns and electric shock was high in the past and the reputation was rather deserved. In fact, welding is now thought to be no more dangerous than crafts such as carpentry and plumbing.
