8. Introduction to pipe welding
Pipe welding generally refers to a set of professional skills used for the joining of pieces of metal. Welding is one of the most cost-efficient means of joining multiple sections of pipe and involves heating pieces of metal and joining them so that the resulting product becomes a single piece of metal. This task generally requires welders to learn several methods of connecting pipes and to understand the factors that affect the quality of the connections that they intend to make. Many of the individuals who engage in pipe welding are professionals who specialize in this area of metal work, and they are usually certified.
Although many individuals may have the ability to weld pipes, the tasks are often reserved for those who are certified. This is because pipes are often used to transport hazardous materials, which can pose a risk to individuals and the surrounding environment if connections or repairs are not done properly. Errors, even when non-hazardous material is concerned, can also be very problematic. Certification generally involves passing a number of tests, which tends to require a person to master several welding techniques in advance.
