What is the History of the Welding Process? What are Welding Methods? What are the Types of Welding and Advantage of Welding? What Is Welding By heating two or more surfaces to a melting point, welding joins two or more pieces of metal or thermoplastic. Typically, this process involves applying heat and pressure to the surfaces being joined, causing the materials to melt and fuse. History of the Welding History of Welding Method/Process · Earliest stage of welding is known as forge welding · 16th century - Soldering process used for brazing silver and copper · 18th century - Gas welding and Arc welding · 19th century - Fusion welding, Metal electrode welding and Carbon arc welding. · 20th century - Electric arc welding Several new...
What is Hydroforming ? Hydroforming is a metal fabricating and forming process which allows the shaping of metals such as steel, stainless steel, copper, aluminum, and brass. This process is a cost-effective and specialized type of die molding that utilizes highly pressurized fluid to form metal. Generally there are two classifications used to describe hydroforming, Sheet hydroforming Tube hydroforming Sheet Hydroforming Sheet hydroforming uses one die and a sheet of metal; The blank sheet is driven into the die by high pressure water on one side of the sheet forming the desired shape. Tube Hydroforming If the shape contains bends that deviate from a straight line, the raw tube is loaded into the tube bender. This bends the tube giving it the necessary curvature in order to fit into the dies. The bent Tube is then typically placed in either our 200 or 500 ton pre-form press. These presses will initiate the forming and shape change of the ...
