Development of linear welding technique for low-weldability materials

Effect of Welding Parameters on the Weldability of Material

In this study, the effect of various welding parameters on the weldability of Mild Steel specimens having dimensions 50mm× 40mm× 6 mm welded by metal arc welding were investigated. The welding current, arc voltage, welding speed, heat input rate are chosen as welding parameters. The depth of penetrations were measured for each specimen after the welding operation on closed butt joint and the ef...

A New Technique for Quality Assessment of Railway Ballast Materials

The influence of main quality tests on the overall quality of railway ballast materials is assessed in this study. The need to integrate all acceptance tests in a unified manner for precise evaluation of ballast quality is identified, and a technique of performing this is proposed. Using this approach, a new ballast quality index (BQI) is defined in which, the main acceptance tests including ab...

DFM – Weldability analysis and system development

Language Learning Materials Development for Teachers’ Professional Development

Coursebooks are normally written to contain information, instruction, exposure, and activities that learn- ers at a particular level need to enhance their communicative competence in the target language. Howev- er, many global course books make attempts to include content, topics, and texts that do not disadvantage any learner around the world. That is why global course books normally do ...

Weldability and Monitoring of Resistance Spot Welding of Q&P and TRIP Steels

This work aims at investigating the spot weldability of a new advanced Quenching and Partitioning (Q&P) steel and a Transformation Induced Plasticity (TRIP) steel for automotive applications by evaluating the effects of the main welding parameters on the mechanical performance of their dissimilar spot welds. The welding current, the electrode tip voltage and the electrical resistance of sheet s...
