Article Synopsis
- Extrusion welding of AlMgSi(Cu) alloys using porthole dies creates hollow shapes with seam welds, but improper alloy composition or conditions can weaken the weld's strength compared to the base material.
- Predictive modeling of welding conditions based on alloy composition, temperature, and pressures streamlines porthole die design, reducing necessary testing and production costs.
- Laboratory tests on two AlMgSi(Cu) alloy compositions showed that optimal welding at 550°C and 350 MPa resulted in significant weld strength, with the highest relative weld strength recorded at 87% for one alloy.
Article Synopsis
- * Detecting diatoms in the rib marrow of corpses can help determine drowning as the cause of death, provided their presence isn’t due to external contamination.
- * Research indicates that diatoms found in rib marrow accurately indicate drowning, while addressing concerns about their potential passive penetration into bone from external sources.
Before artificial ageing, extruded aluminium profiles are subjected to stretching with a small cold deformation in the range of 0.5-2%. This deformation improves the geometrical stability of the extruded product and causes changes in the microstructure of the profile, which leads to the strain hardening of the material after artificial ageing.

Addressing this need, this paper presents a study on the innovative use of aluminum extrudates in construction. Focusing on the AA6005 alloy, which is known for its excellent balance of strength, corrosion resistance, and weldability, this research delves into the development of an extrusion process that yields thin-walled, lightweight, yet high-strength structural components.

- * The research focused on three variations of 7021 aluminum alloy and evaluated weldability at temperatures of 400, 450, and 500 °C under a pressure of 300 MPa.
- * Results showed that high-strength welds (96-101% of non-welded material strength) can be achieved by optimizing alloy composition, die construction, and deformation conditions during industrial extrusion trials.
