Abstract

Tungsten inert gas (TIG) welding had been applied to produce four double-V butt welded joints performed on thick plates made from 6082-T6 aluminum alloy. The thicknesses of the plates are 18, 45, 60, and 80 mm. This type of aluminum alloy is very sensitive to heat due to its high conductivity and high thermal expansion coefficient. Heat from TIG welding reduces the strength of the cited welded plates in the welding zone and in the heat affected zone (HAZ) and favorites the formation of porosities and solidification cracks in the welded joints. Porosities and solidification cracks are the most frequent imperfection that appear in this type of welded joints and they are often the reason which prevent them to comply with the requirements of the BS EN ISO 10675-2: 2017 Non destructive testing of welds: Acceptance levels for radiography testing—Aluminium and its alloys, and of the BS EN ISO 23277: 2015 penetrant testing of welds—Acceptance levels. This article represents the type of the filler metal that used and the welding parameters that applied to perform TIG welding of the cited thick plates in order to get welded joints that are free from porosities and solidification cracks as confirmed by X-ray radiography and by red dye penetrant testing of these welded joints.
