Professional Fabrication Sheet Metal Welding Part

Metal working is defined as the process through which a specific metal based material undergoes physical or a chemical change, with the intention of producing a new material with specific shape, size or even desirable properties. It includes the following major types of processes:It includes the following major types of processes:
1. Casting: An activity that involves pouring of molten metal into a mold that is already cast and then cooling the metal to harden into the intended shape.
2. Forging: A technique by which use is made of forces from outside (e.g. hammering pressure) to shape the metallic component in the solid state with the desired characteristics.
3. Machining: The process, where through techniques such as cutting, grinding, drilling among other operations, the metal material is reduced in order to gain the correct size and the ideal surface coarseness.
4. Welding: The practice of utilizing heat to fuse metals in order to develop joints that are strong.
5. Heat treatment: Changing the micro structure of metals through service heat treatment processes that include heating and cooling to increase metals’ performance.
6. Surface treatment: Containing sandblasting or sand-blasting, electroplating, painting, and so on, to enhance the anti-corrosive property, wear-resistant property, or appearance of metal surface.
7. Forming processing: The shaping of metals by means of a mold and pressure exerted in forming the metal materials into desired shapes and sizes etc., which include, stamping, stretching.
8. Special processing: Such as laser cutting, ultrasonic treatment, electron beam treatment and other for special material or special needs.
These processes can be employed singly or in harmony depending on the production requirements and type of products to be produced.
