Welding is the most common process used to join two pieces of metal together permanently. The process uses a strong electric current generated between the metal and the welding rod to create very high temperatures allowing the center of the rod and the metal to fuse together, cooling quickly to form a solid bond. It is possible to use different kinds of material in the welding rod to form bonds with different metals, or to form different kinds of welds for specialist processes.
Welding can be a very skilled job, some applications needing highly skilled people to use metal to form all different kinds of shapes for different applications. Welding is used in shipbuilding, aerospace applications, automobile manufacturing and bodywork repair, and engineering construction applications.
Welding schools offer many different kinds of courses. Some courses are just for a few weeks, to add to the skills of workers for whom welding is another skill to add to their array of skills, to several years of combined classroom instruction and on-the-job training, with certification to give verification to the levels of expertise. Some courses involve come knowledge of computing, as computer controlled machines and robots are often programmed by skilled and experienced welders.
Earnings are around $13.13 per hour, with skilled and experienced welders earning as much as $20.74.
