Application of Powder Plasma Method to Braze Finish Portion

摘要

Car manufacturing needs to be operated with maximum efficiency at optimum capacity of manufacturing facilities. For this purpose, a smaller sized press method applied for divided panels was adopted for pressing outer side panel of Legacy. For medium-scale production, relatively small machines can be used instead of super sized press machine by using divided pieces from a single piece panel. However, the issues of this method are how to reduce the cost for the divided panel welding and how to secure the quality of completed panels. To deal with these issues, powder plasma welding was developed and applied to SUBARU B9 TRIBECA, in addition to the conventional MIG welding. Powder plasma welding reduces thermal (heat) deformation and simplifies the finishing work by the operator. This paper introduces the outline and extended subsequent application of the powder plasma welding technology.
