What type of structure is aluminum? The first thing that comes to mind is the boat. Growing demand for aluminum hull commercial and military aviation.
Why? Aluminum is lighter and save fuel and increase speed.
AWS D1.2 structural code for welding aluminum. This is not only the design of welded joints and constraints, but also how to weld aluminum welder must be certified.
The most important process used in the structure of aluminum gas tungsten arc (TIG), Gas Metal Arc (GMAW) and the variable polarity plasma arc (VPPAW) welding. Arc welding process, the major shipbuilding industry, but is seen as a friction stir in the examination of future possibilities.
Along with the need for certification of welders, it is important to develop procedures to meet the requirements for aluminum structures. Aluminum can waste a lot of power when the army and welding procedures are used to great effect in the results. Typically, the battle for adequate heat input to be used in order to limit the porosity, while at the same time using the low heat input is not sufficient to affect the strength and other physical properties of the alloy.
Carbon steel to harden when exposed to temperatures high enough and then quickly cooled. This is how we make the knives and the like.
But aluminum is the opposite. At high temperatures, such as during heat welding, which soon began to lose strength, good thermal alloy can be treated as 6061 T6, H14 or 3003 In each case, the loss of toughness and strength when heated enough. Rapid cooling after heating to ensure tenderness only.
AWS D1.2 met requires the use of qualified welding procedures to ensure the minimum tensile properties in the weld metal and heat affected zone.
