| Summary: | 碩士 === 國立屏東科技大學 === 材料工程研究所 === 105 === This research is aim to discuss the influence of adding A-RSW in soldering process to the feature of soldering stainless steel. Steel materials are applied with 2 mm of 304 stainless steels; planting materials are M6 and M8 of 304 stainless steels, activated powder is SiO2. The research reveals stainless steel stud sequentially displays incomplete melt in completely melted and fused melt fracture when improving the welding current or welding time, in the condition where the length of protruding planting nail and arc length are the same. Because the active Stud arc welding processes can increase the contact resistance, the use of a lower welding current or welding time can be shorter Stud Welding. Compared with traditonal arc welding stud, active arc welding stud can effectively improve stainless steels and the channel penetration. The study has found that the soldering process of active arc stud can enhence stainless steel weld residual ferrite content: furthermore, being able to aquire the stainless steel soldering channel hardness rate of more traditional arc welding process.
