示した図面とともに、詳細に説明する。Another method is to apply aluminum plating to the steel base material and then weld it, but this method causes weld cracks. Taking the above points into consideration, the present invention involves forming a thermal spray coating by depositing aluminum or an aluminum alloy on the steel base material by thermal spraying when joining the two base materials, which cannot be joined by direct welding. (The joint is then formed by arc welding.) Next, the present invention will be described in detail with reference to drawings showing embodiments thereof.
