Weld | Rectangular Hollow Section tests

Done over 17 days, these 3 projects form a progression.

Each of the 3 projects aims to test welds - with interest in its relation to the "substrate" section, the RHS (Rectangular Hollow Section), under load.

Various objectives were served. The propulsion of the test series through its 3 projects was the objective of testing the test welds:

• "U-RHS" - tested the Section more than the butt weld
• centre-weld test beam - achieved test of the butt weld
• fillet weld test beam - provided a test for fillet welds

The three projects:

• U-weldment in R.H.S. - fabricate, analyse, test
• Weld test - weld at centre of simply-supported beam
• Fillet welds tensile tested in beam test

Proposal to research welded high-strength steel cyclic-loaded structures

In January 2021, I present
Proposal : research path to high-strength steel fatigue-resistant welded structures
which seeks a host for this investigative programme aiming to make use of the observation that fillet welds can show fatigue resistances approaching those of the steels they are joining.
