Camera based closed-loop control of laser micro-welding processes by observation of the full penetration hole

In macro welding-processes, monitoring and closed-loop control by using the so-called “full penetration hole” is well known. This paper reports first results for the transfer of this technology to laser micro-welding processes for lap joints as they are used for housings or fuel cells. The laser source was a 400 W cw fiber laser with a Gaussian beam profile and a spot size of 28 μm. A cellular ...

Ovality and Bow Defect of Pre-punched Sheets in Roll Forming of Trapezoidal Sections

Roll forming process is used for manufacturing sheet metal parts by successive bending and creating the final shape with gradual deformation. In this article, deformation of a pre-punched sheet due to the roll forming process was studied. Two main defects in the roll forming process are ovality of holes and bow defect. The ovality of the hole is influenced by the process parameters including sh...

Optimization of the parameters of low-carbon steel (EN10130) welding using friction stir welding method

  Friction-stir welding process is a novel method of solid state welding, which produces heat due to friction between the pin, the shoulder and the workpiece. This heat causes a paste area. Shoulder pressure and pin spin cause edges integration and lead to welding. In this study, firstly, the feasibility of welding of steel sheet (EN10130) with a thickness of 1.5mm has been tested by 58 experim...

Microstructural Evolution of Roll Bonded Al-Clad Stainless Steel Sheets at Elevated Temperatures

The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...
