Welded metallic structures are usually prone to different forms of degradation in the mechanical properties during their life span such as fatigue. Tungsten Inert Gas remelting is a post-weld treatment method which gained increasing interest last decades. However, more light should be thrown on behavior existing cracked retrofitted by TIG-remelting. Therefore, fatigue test results several welde...

This study investigates a parametric multi-objective optimization of the Tungsten Inert Gas-Metal Gas (TIG-MIG) hybrid welding AISI 1008 mild steel joints. A combined grey relational system theory and Taguchi method was used for process towards achieving set parameter that maximizes both ultimate tensile strength 0.2% yield structural applications. An L-9 orthogonal array based on adopted exper...

For decades now, Fronius has exerted a significant influence on the progress achieved in welding technology, and is regarded as a global technological leader. In robotic welding too, about 30% of the power sources used worldwide are supplied by Fronius. To continue to play this dominant role in the world market, the company opened a new Research and Development Center in Thalheim (Upper Austria...

Stainless steels and mild are widespread materials in several industries. The dissimilar welding of is a technique used to meet the needs various Mild steel 316L austenitic stainless have different chemical compositions thermal mechanical properties. Therefore, it would be interesting develop flux paste that ensure reliability sustainability welded structures made materials. In this work, pseud...

As organic porous soil, peat is prone to self-heating ignition, a type of spontaneous initiation fire that can take place at ambient temperatures without an external source. Despite the urgency tackle fires, understanding ignition insufficient. In this study, computational model integrates mechanisms heat transfer, mass transfer and chemistry incorporated with three-step reaction scheme include...
