This is a tack-welded stainless steel tee (three-way pipe fitting). Wall thickness: 1.65 mm. Diameter: 50.8 mm. It requires manual TIG welding with full penetration using a single-sided welding, both-side forming technique. The weld produces both an internal bead and an external bead. After welding, cutting shall be performed based on the actual dimensions Outside […]
This document outlines the autogenous TIG welding workflow and process parameters for 316L stainless-steel 90° elbow fittings (25.4 mm × 1.68 mm) typically used in semiconductor vacuum systems. The procedure is based on the Panasonic YC-400TX4 TIG welding machine and is specifically optimized for elbows that consist of an outer sharp corner and an inner
一、 Project Background This project involved tack welding a 316L stainless steel high-purity tube to a flange. The tube thickness was 1.6mm, welded by TIG at 39A using 0.8mm filler wire. High-purity argon was used for back purging to keep the weld interior clean and oxidation-free. 二、Welding Parameters Item Specification Process TIG (GTAW) Material 316L
