Description of the Related Art Conventionally, a large gun for spot welding is mounted on a robot, or is suspended as a portable gun by a balancer or the like, and a human moves it to a welding position for use. For this reason, lightweight gun arms made of light metal such as aluminum and aluminum alloys have been adopted for robot guns due to restrictions on transportable weight and for portable guns due to their operability.

となっている。However, since arc welding is used in the main manufacturing process in this conventional manufacturing method, an aluminum alloy material that can be used from the viewpoints of weldability, weld strength, etc., is 5000 series (Al-Si). However, as a gun arm material, it is unsatisfactory in terms of fatigue strength. In addition, there are many pre-processes of welding in the manufacturing process, and more time is required for welding and strain relief, resulting in higher overall costs.
