The influence of welding parameters on weld characteristics in electric arc stud welding [PDF]

open access: yesMetalurgija, 2008
In this paper the influence of welding parameters on weld geometry during stud welding (Drawn Arc Welding process with ceramic ferule) on steel plate and pipe is analyzed as a variation of weld penetration. Also, the changes of weld characteristics are certified trough measurements of HV0, 2 across the weld joint, and analysis of hardened zone.

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

open access: yesAdvanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Braze Welding TIG of Titanium and Aluminium Alloy Type Al – Mg

open access: yesArchives of Metallurgy and Materials, 2016
The article presents the course and the results of technological tests related to TIG-based arc braze welding of titanium and AW-5754 (AlMg3) aluminium alloy. The tests involved the use of an aluminium filler metal (Al99.5) and two filler metals based on

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

σ-phase precipitation in weld metal of austenitic stainless steels and its effect on properties

open access: yesHanjie xuebao
Low-temperature conditions necessitate high toughness in the welded joints of austenitic stainless steel structures. However, the impact toughness of the weld metal decreases significantly when using electrodes developed for SMAW under such conditions ...

The influence of the weld toe grinding and wig remelting weld toe rehabilitation techniques, on variable stresses, in case of cross fillet welds, reinforced with additional welding rows

open access: yesMATEC Web of Conferences, 2017
Variable stresses where the load value varies between a maximum and a minimum value, or varies the position in time, cause after accumulating a large number of load cycles in those structures, the emergence of drug fatigue.

Mitigation of welding distortion and residual stresses via cryogenic CO2 cooling - a numerical investigation [PDF]

open access: yes, 2008
Fusion welding remains the most common and convenient fabrication method for large, thinplate welded structures. However, the resulting tendency to out-of-plane distortion exacts severe design and fabrication penalties in terms of poorer buckling ...

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

open access: yesAdvanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.
