orbital welding ppt free download

Orbital welding first found use in the 1960 s when the aerospace industry recognized the need for a superior joining technique for aircraft hydrolic lines. The solution: a mechanism to rotate a welding arc from a tungsten electrode around a tube-weld joint. Regulating weld current with a control system automated the entire process. The result was a more precise, reliable method than manual welding.

Purpose

To provide leak proof joint between Tube to Tube sheet in Condenser in addition to Forced expansion. ....etc

Hyperbaric welding is the process of welding at elevated pressures, normally underwater. Hyperbaric welding can either take place wet in the water itself or dry inside a specially constructed positive pressure enclosure and hence a dry environment. It is predominantly referred to as hyperbaric welding when used in a dry environment, and underwater welding when in a wet environment. The applications of hyperbaric welding are diverse it is often used to repair ships, offshore oil platforms, and pipelines. Steel is the most common material we ....etc

Underwater Welding

Welding is an unavoidable process of modern engineering ? civil, electrical, mechanical, automobiles, marine aeronautical ? in all branches. It is used in fabrications and erections in infrastructures and installations. It joins metals or thermoplastics. Forming a pool of molten mass ? the weld puddle ? and allowing it to cool to become a strong joint is the basis of the process of welding. For repairing to be carried out underwater, there is a separate process. That is called un ....etc

Introduction
Agitated friction welding (FSW) is a solid state bonding process that uses a non-consumable tool to join two work pieces that face without melting the workpiece material. The heat is generated by friction between the rotating tool and the workpiece material, which leads to a smoothed region near the FSW tool. While the tool is traversed along the joining line, it mechanically intermixes the two pieces of metal, and forges the hot and smoothed metal by the mechanical pressure, which is applied by the tool, as well as joini ....etc
