Laser welding technology for skin-stringer joints is widely used in aircraft manufacturing. Double-sided laser beam welding of skin-stringer joints is an approved method for producing defect-free ...

After the completion of pipeline girth welding joint, the joint may be strengthened or softened and have high residual stress. Most of weld indies are acceptable, but when pipeline work under inner ...

The welding current intensity was I s 210A, the arc welding voltage U a =25V, the welding speed V e =2.54x10 -3 m/s. and therefore the heat input Ei=207x10 4 J/m. The welding joint was made by a MMAW ...

2.2. Welding process Inconel 718 and AISI 316L plates were welded in the butt joint position without bevel by an autogenous GTAW process with a welding speed of 4.5 mm s -1 using a multi-pass ...

This paper focuses on the analytical procedure for determining novel exact expressions for internal forces and displacements of hemi-ellipsoidal shells formed as an axisymmetric shell of revolution ...
