Abstract
This paper investigated the effects of process parameters such as burn off distance, oscillating frequency, and forging pressure on linear friction welding of commercially pure aluminum. Friction welding (FW) techniques are a group of techniques that are based on frictional heat between components that occurs during movement while under pressure. Linear Friction welding is a solid-state process in which one part moves in a linear fashion at high speed and presses against another part that is held stationary. Linear friction welding (LFW) is a very well specialized technology used by global gas turbine engine manufacturers to create bladed disc assemblies. The sample bar with a cross section of 25mmx25mmx140mm was used for the experimental testing. The results were obtained by maintaining amplitude and frequency at 1.5mm and 40Hz, respectively, and forging pressure at 10MPa, 15MPa, and 20MPa. It is observed that, Lower HAZ. Burn-off distance grew as forging pressure increases with time.
