Underwater welding refers to a number of distinct welding processes that are performed underwater.

The two main categories of underwater welding techniques are wet underwater welding and dry underwater welding, or hyperbaric welding.

In wet underwater welding, a variation of shielded metal arc welding is commonly used, employing a waterproof electrode. Other processes that are used include flux-cored arc welding and friction welding. In each of these cases, the welding power supply is connected to the welding equipment through cables and ....etc

Plastics are considered to be building blocks of technology related structures of modern era. The development of polyvinylchloride, made in Germany, triggered extensive research and development in plastic fabrication work. Critical storages of alloying elements of corrosion resistance steel as well as other technological applications stimulated the use of plastic structures during the Second World War. In plastic welding smaller components are welded together to form complex structures. These structures include installation of process lines ven ....etc

Definition

Welding technology has obtained access virtually to every branch of manufacturing; to name a few bridges, ships, rail road equipments, building constructions, boilers, pressure vessels, pipe lines, automobiles, aircrafts, launch vehicles, and nuclear power plants. Especially in India, welding technology needs constant upgrading, particularly in field of industrial and power generation boilers, high voltage generation equipment and transformers and in nuclear aero-space industry.

Computers have already entered the field of weld ....etc

Abstract:
Voltage sag are the major source of power quality related problems. Dynamic Voltage restorers (DVR) are used to protect sensitive loads from the effects of voltage sag on the distribution feeder. It injects voltage in series with the system voltage to compensate the sag. This paper presents a power system operation with PI controller approach. Total Harmonics Distortion (THD) is calculated for the system in absence of compensation scheme next THD is evaluated when DV ....etc

Orbital welding became practical for many industries in the early 1980s when combination power supply /control systems were developed that operated from 110 VAC and were physically small enough to be carried from place to place on a construction site for multiple in ?place welds. Modern day orbital welding systems offer computer control where welding parameters for a variety of applications can be stored in memory and called up when needed for a specific application. The skills of a certified welder are thus built into the welding system, prod ....etc
