About Course

Metal casting and welding is a section of manufacturing process to attain the desire shape and size of the product/components from the raw material.Various methods of casting and welding process that are to be adopted in the manufacturing of the product/components depends on many parameters such as material, product/component specified properties, surface finish etc. Hence knowledge pertaining to these parameters that affects the quality of the product/component has to be acquired for the selection of particular process has been covered in the course content which is an important task of an engineer. Thus, engineers involved in these manufacturing sectors must acquire the basic knowledge of Metal casting and welding process by studying this course.

What Will You Learn?
