Hi Guys,
I am laser welding thin (0.5mm) 430LNT (Ti, Nb stabilized for welding) using a 2kW Rofin 1070nm fiber laser using an automated production machine. We have been playing around with applying protective gases such as Nitrogen, Argon, and Helium via Ø4mm nozzle and found that the welds are...
Hi Guys,
I am currently doing a research and development project into fibre laser welding of thin ferritic stainless steel (430LNT). 430LNT is a weldable grade of stainless which has been stabilized with Titanium and Niobium. We have had the material tested and is within the 430LNT specs of...
Hi Guys,
I'm currently doing a research and development project in laser welding thin (0.5mm) stainless steel using a fibre welder (Rofin 2kW 1070nm CW) and have notice a phenomenon in which the weld becomes up to 20% more ductile as its aged over a couple of days verses tested straight away...
Hi There,
I'm looking at getting this part manufactured out of copper which has internal cooling chambers. It needs to be made from 1 piece and needs to be water tight. Does anyone know of a process that can produce this?
Approximate dimensions are 500mm x 60mm x 25mm
Ideally I would like to...
Hi There,
This is not a student question, it is a heat exchange that I have been designing in which I already know the physical size, material, etc of the heat exchanger but I would like to get an idea of what kind of temperature change I’m going to get by calculation rather than physical...
