Welding is a sculptural process for joining metals or thermoplastics. It is a two stage process involving melting and cooling. The operation uses coalescence. Heat is the main character in the process. The scope and applications of welding are large. It is used for industrial purposes, for construction, aerospace, tubing, instrumentation, etc.
- TIG (Tungsten Inert Gas) Welding: this is also known as Gas tungsten arc welding (GTAW). It is a type of arc welding process. The main application of TIG is in aerospace, construction (piping), tool and die. The process uses a non-consumable tungsten electrode to create the weld. The operations are carried out with in an inert shielding to protect from atmospheric containment. Such operations definitely require assistance from automation service providers.
- MIG (Metal Inert Gas) Welding: MIG is also known by GMAW-Gas Metal Arc Welding or MAG- Metal Active Gas. It is another welding technique used by industries. It is usually preferred for industrial use due to its potential and complexity. MIG uses a consumable wire electrode. Automating the operations creates a less-complex and much efficient system.
- Spot Welding: resistance spot welding is a technique more effective for the automobile and aerospace industry. Its method uses two pointed electrodes and the pressure principle to build weld.
- Ultrasonic Welding: USW uses high frequency vibrator energy to built weld. When this energy is passed through foils, plastic, or thin metal sheets weld is created. This method is more used by the electronics and solar industry and for building the rear lights of cars.
