Among the most popular and common kinds of welding being used today is arc welding. Yet the average layman strolling the street has little understanding of this welding process other than observing the blinding light flashing from a building job site they might be strolling past at rush hour. Welding is essentially simply a combination process for bonding metals. The metals are simply melted together by intense heat and fused as one piece. Welding makes the bonding of 2 pieces of metal with the very same strength as a single continuous piece if done correctly. A welding joint is preferd to gluing since through the welding procedure, the metals are in fact melted together instead, utilizing the bonding characteristics of glue to hold them together. In commercial applications, heat treatment is also required to avoid weld failure later on. This company offers on-site services:

There are a number of techniques of welding and arc welding is one of the most popular. The term arc welding comes from the fact that an electrical arc is produced to produce intense heat. This arc is formed in between the metal being worked on and an electrode connected to the arc welder.
At its heart, arc welding is about producing an electrical circuit. The metal piece you are attempting to bond ends up being part of the electrical circuit by connecting a cable from the arc welder to metal. An electrical arc is created in between the metal work piece and the electrode when the electrode is held close to the metal.
Besides creating heat, the arc produces a very bright light. This light is harmful to the welder and those around the welding task location. You must not look directly into the arc without appropriate eye safety equipment. The visible light is not the only threat. The arc offers of infrared and ultraviolet light that is invisible to the naked eye. This is why welders use vehicle darkening welding helmets. These helmets will immediately darken when the arc is struck to shield the welders eyes from the bright visible and the lens filter is created to keep out infrared and ultraviolet light at all times whether the lens is darkened or not. Welders also put up welding blankets or guards to safeguard other individuals in the work area that might not have correct eye protection.
Despite these dangers arc welding is a dependable and safe technique for fusing metal together and with some practice anyone can become qualified enough for standard welding.
In Summary
One of the most common and popular types of welding in use today is arc welding. There are a number of methods of welding and arc welding is one of the most popular. The term arc welding comes from the truth that an electrical arc is developed to produce extreme heat. At its heart, arc welding is about producing an electrical circuit. An electrical arc is developed in between the metal work piece and the electrode when the electrode is held close to the metal.
