Abstract: Welding distortion of 6005A aluminium alloy was straightened by flame heating. Effects of temperature on tensile strength, hardness and microstructure of 6005A aluminium alloy welding joint by flame heating were studied. Experimental results showed that tensile strength, hardness and microstructure in soften zone were unchangeable clearly under 200°C , whereas tensile strength and hardness decreased apparently when the heating temperature was above 200°C . The decrease of properties in soften zone is due to the overheat, which leads to crystal coarsening during the influence of the straightening heat.
