Welding is an important factor in the industrial world because welding is used in all aspects such as joining, repairing or repairing materials. In various aspects of welding, failures often occur, either broken, or defects that cannot be seen by the naked eye. Therefore, testing in welding joints becomes necessary to see whether the welding can be said to be good or bad. Various welding tests that are familiar are microstructural testing and macrostructural testing. These two tests have different roles or functions, for microstructural testing it is useful to see the density of a weld, to determine the type of phase formed in a welding, to determine grain boundaries, and so on. Meanwhile, for macrographic testing, the function is to find out into a welding, find out the defects that occur in the welding and so on. For more clarity the author will discuss metallographic testing in a welding.

In recent years, the use of polymers has increased in various industries. Not only in the home industry, but polymers have also played a big role in the automotive industry. Examples of polymer applications in the automotive industry include the use of headers on mirrors and vehicle plates. There have been many studies that reveal the properties of polymers that can be equated with metal materials. In addition, the availability of polymers is considered easier to obtain than metal materials. It's just that there is still a need for more research in this regard. Plastics processing involves many of the same operations as metal production. Plastics can be molded, poured, and shaped as well as processed by machining and joining. Plastic raw materials are often found in the form of pellets or powder. Plastics are also available in the form of sheets, plates, bars and pipes. Plastic processing methods can be done by: extrusion, injection molding, casting, thermoforming, blow molding and others. Injection molding is one way that can be done in producing components from plastic materials.
