One of the most popular and typical types of welding in use today is arc welding. If done properly, welding makes the joining of two pieces of metal with the same strength as a single continuous piece. A welding joint is preferred to gluing because through the welding procedure, the metals are really melted together instead of utilizing the bonding properties of glue to hold them together. In commercial applications, pwht is also essential to avoid weld failure later on. This business offers on site services:

The key concept in welding is a heat source is needed in order to fuse the metal together. There are several approaches of welding and arc welding is among the most popular. The term arc welding originates from the fact that an electrical arc is produced to produce extreme heat. This arc is formed in between the metal being dealt with and an electrode linked to the arc welder. The electrode rod is moved along the joint and is melted by the electrical arc. The rod has two functions. One is to assist produce the arc and the other is it makes a filler material as it is melted.
At its heart, arc welding has to do with producing an electrical circuit. An arc welder requires an electrical power source that produces either alternating current or DC. The metal piece you are trying to bond is a part of the electrical circuit by connecting a cable from the arc welder to metal. The other hot cable is attached to an electrode that the welder is holding. When the electrode is held close to the metal, an electrical arc is produced in between the metal work piece and the electrode. Now there is a complete electrical circuit in between the arc welder and the metal. This process creates some pretty fantastic temperatures. The point of the arc can reach temperatures in excess of 6500º F. Now there is sufficient heat to fuse the metal pieces together and develop a strong bond. To spark the arc, the electrode should be pushed up to the metal and then pulled away.
Creating heat, the arc produces a really intense light. The arc generates infrared and ultraviolet light that is invisible to the naked eye. Welding helmets will immediately darken when the arc is struck to protect the welders eyes from the bright visible light and the lens filter is designed to keep out ultraviolet and infrared waves at all times whether the lens is darkened or not.
In spite of these dangers arc welding is a reliable and safe technique for fusing metal together and with some practice anybody can become proficient enough for basic welding.

One of the most typical and popular types of welding in use today is arc welding. There are numerous approaches of welding and arc welding is one of the most popular. The term arc welding comes from the reality that an electrical arc is developed to produce intense heat. At its heart, arc welding is about developing an electrical circuit. An electrical arc is produced in between the metal work piece and the electrode when the electrode is held close to the metal.
