Welders, who may also be referred to as soldering and brazing workers, use heat to fuse and mold metal together. This is a process that permanently joins metal. The art of welding is commonly used in shipbuilding, automobile manufacturing and repair, aerospace applications and other manufacturing activities because of its power and strength. Many welders may also use their technique on construction buildings and bridges.
There are many types of welding equipment. They range depending on the welder’s needs and preferences. There are flat, vertical, horizontal and overhead. There are two types of welding that are primarily used; manual and semiautomatic. In manual welding the work is done entirely by the welder. Semiautomatic welding is done using machinery like a wire feeder to perform the specific task.
Welding may seem to be pretty simple but in truth it is fairly complex. There are about one hundred styles and types of welding but Arc welding is the most popular. Arc welding involves the use of two large “alligator” clips that work together in the efforts to create a strong electrical current. One clip is placed on the piece of work and the other is connected to the welding rod. Once the welding rod connects to the work piece the electrical circuit works to create a conversion using heat. In order to ensure the high quality of the weld, it is important to work with speed and precision. The cooling process is what actually forms the bond while an inert gas is released to protect the piece from different elements.
There are primarily two types of Arc welding forms used. They are Tungsten Inert Gas (TIG) and Metal Inert Gas (MIG). TIG welding is commonly used to work on stainless steel and aluminum and is used with welding rods. MIG welding allows the welder to weld continuously with out replacing the metal rod. It utilizes a pool of continuously fed wire that makes it possible to join longer pieces of metal. TIG welding is the form that is more commonly known. The welder holders the rod in one hand and the torch in the other and uses a mask to shield the eyes due to the closeness of the work. In MIG welding the welder will simply hold the wire feeder.
It is becoming more common practice to incorporate the use of automated welders. In this case a welding machine operate would supervise the machinery in order to monitor the work and progress. It is important, in this business to be consistent and precise when following specific layouts. Operators must be competent enough to load parts correctly while monitoring all aspects of the job.
