the definition of
Weld gained access in almost every industry; name a few bridges, ships, railroad equipment, building structures, boilers, pressure vessels, pipelines, cars, aircraft, launchers, and nuclear power plants. Especially in India, welding needs constant updating, particularly in the area of industrial and power boilers, high-voltage equipment and power stations and nuclear air and space industry.
Computers have entered the field of welding and the present situation is that the engineer of a welder who has little or no computer skills soon will be hard-pressed to meet the challenges of our welding process times. To numerical solution must be implemented, educators cannot escape their share of responsibility.
Automation and Robotics are two closely related technologies. In the industrial context, we can define the automation technology, which involves the use of mechanical, electronic and computer systems in operation and production management. Examples of this technology include automatic, mechanized Assembly machines, contact management systems, machine tools with numerical control, and robots. Accordingly, Robotics is a form of industrial automation.
There are three main classes of industrial automation: Automation, programmable machine Fixed and flexible automation. Fixed automation is used when production volume is very high, and it is therefore advisable to develop a specialized equipment for the processing of product very efficiently and with high performance. a good example of fixed automation can be found in the automotive industry, where a high degree of integration of automatic lines, consisting of a few tens workstations are used to perform operations on the motor and transmission components. Economy fixed Automation such that the cost of special equipment can be divided into a large number of units and as a result of low unit cost compared to alternative methods of production. the risk faced by fixed automation is this: with the initial investment cost is high, if the production volume is lower than expected, the unit costs become more than expected. Another problem in a fixed automation is that the equipment is specifically designed to produce one product, and the product life cycle is completed, the equipment can become obsolete. For products with a short life-cycle, using fixed automation is a big gamble.
Programmable Automation is used when production volume is relatively low, and there are plenty of products that will be made. In this case, the production equipment is intended to be adapted to changes in the configuration of the product. This adaptability is achieved by working with equipment running "program" commands that have already been prepared specially for this product. Reader in production equipment, and the equipment performs a specific sequence of machining operations to make this product. In terms of the economy, the cost of firmware can be divided into a large number of products, while products are. Due to the programming features and, as a result, adaptive equipment, many different and unique products can be made economically in small batches.
