Welding is a manufacturing process which joins two materials, typically metals or thermoset thermoplastics, in order to fuse them together by subjecting the surfaces to high heat and then letting them cool, leading to fusion. Welding is different from other heat-fusion methods like brazing and welding, which don’t melt the base material at all. There are many different kinds of welds, each having its own advantages and disadvantages. Generally, however, welding is used for joining two pieces of similar size and weight that are fastened securely to one another. The welding industry has developed a wide variety of different types of welding equipment and products, but all welders require similar basic tools.
Many kinds of welding equipment and machines are available, with some being better than others. One of the most popular and successful types of welding is friction stir welding, or MIG (Metal Inert Gas). The reason for this is the ease of use – the welder simply holds the metal part in place with pressure, applies the heat, then holds it still for the welding process. Many welders hold one hand in the center of the arc and use the other to steady the ark. The welder is not wearing any protective gear, so the chances for flying sparks are almost non-existent, as long as you follow the manufacturers’ safety precautions.
Many welders begin their careers with general electrical welding programs. These programs offer hands-on training in both the theory and practice of welding, and many trainees choose to continue their education with on-the-job classes. Hands-on practice allows students to become more familiar with the operations of the welder, while practicing methods they have already learned in class. After gaining experience and gaining hands-on practice, most welder students decide to take more advanced welding courses and programs. These classes often include classes on shielding, gas tungsten arc welding (GTCW), flux cored welding, and plasma cutting.
A high school graduate who wishes to become a welder can begin by taking general welding classes at his or her local community college. If these classes are satisfied, a vocational/trade school will offer specialized classes that lead to a certificate. Once qualified, a student can look for an experienced job on an as-needed basis at a shop or factory that uses welders on a regular basis. Some welders work as contractors directly after graduating from high school or as apprentices under another welder. While a career path in welding might seem closed to some people, it actually opens doors that may not otherwise be there.
High school graduates that want to take advantage of the welding industry can either go straight to a welding school or enroll in a vocational course that will lead to a certificate. Many welders also complete their apprenticeship in order to gain the hands-on experience that they need to help them succeed on their own as welders. However, because this career path is hands-on, it is usually required that new welders take a few months to several years of apprenticeship before they are allowed to start working with their own and their employer’s welding machines.
To be an effective welder, it is necessary for a welder to understand and learn about welding processes. The types of welding processes available depend on the type of metal being used and the type of welding being performed. There are also other factors involved in the choice of welding processes for various types of metals and different welding positions. A person who wants to be a welder must have a desire to learn about all of these factors. If you are interested in becoming one, there are many ways to get started.
