Arc Welding Fundamentals
One of the most typical and popular types of welding in usage today is arc welding. If done properly, welding makes the bonding of 2 pieces of metal with the very same strength as a single solid piece. A welding joint is superior to gluing since through the welding process, the metals are in fact melted together rather than using the bonding characteristics of glue to hold them together. In commercial applications, pwht is also essential to prevent weld failure later on. This business provides on site services:
The essential concept in welding is a heat source is needed in order to fuse the metal together. There are a number of methods of welding and arc welding is among the most popular. The term arc welding originates from the truth 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. The electrode rod is moved along the joint and is melted by the electrical arc. The rod has 2 purposes. One is to help produce the arc and the other is it makes a filler product as it is melted.
At its heart, arc welding is about producing an electrical circuit. An arc welder requires an electrical power source that produces either alternating current or direct current. The metal piece you are attempting to weld becomes part of the electrical circuit by connecting a wire from the arc welder to metal. The other hot wire is connected to an electrode that the welder is holding. An electrical arc is created in between the metal work piece and the electrode when the electrode is held close to the metal. Now there is a total electrical circuit between the arc welder and the metal. This process creates some pretty amazing temperature levels. The tip of the arc can reach temperature levels in excess of 6500º F. Now there is enough heat to fuse the metal pieces together and produce a strong bond. To ignite the arc, the electrode should be pushed against the metal and after that retreated.
Developing heat, the arc produces a very bright 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 shield the welders eyes from the intense noticeable light and the lens filter is created to keep out infrared and ultraviolet waves at all times whether the lens is darkened or not.
In spite of these dangers arc welding is a reliable and safe method for merging metal together and with some practice anyone can end up being skilled enough for standard welding.
