Abstract: The automatic girth welding equipment is applied to welding engine tubes.The processing parameters which were suitable for the φ6 austenite stainless steel tube with thickness of 0.8 mm were determined.According to visual inspection and X-ray inspection,the girth welding tubes meet the welding requirements and percent of pass is more than 95%.As a result,in the case of aircraft engine tubes,the automatic welding can base on these experimental results.
Keywords: Austenite stainless steel; Tubes; Automatic girth welding
