Even With Volkswagen AG: Ophir’s BeamWatch System Optimizes Laser Process Development

The laser seam welding of sheets of zinc-coated steel – a combination of metals with disparate melting and evaporation properties – used to be a major challenge for the automotive industry. But Volkswagen AG is pursuing a promising approach with multi-focal laser welding: A newly developed process enables significantly higher welding speeds than is otherwise…

Why and How to Profile Challenging Laser Applications

We introduce three techniques for monitoring the critical characteristics of the beam as the laser is used in three very different applications: (a) VSCEL / Laser Diode Mode and beam divergence, (b) Additive Manufacturing lasers used is 3D SLM / SLS, and (c) Fiber welding / heat treating / cleaning lasers. We will discuss three…

Maintain Proper Laser Beam Parameters for Additive Manufacturing

Additive manufacturing (AM), including selective laser melting (SLM) and 3D printing, relies on its laser source to properly manufacture 3D-printed parts. The laser is at once the most essential element of the system, and the most vulnerable to degradation. Here are some of the malfunctions that can occur with an unmonitored laser system: Optical pass…

Ensure Quality Laser Welds for High Pressure Vessels

High pressure vessels (over 100 PSI) have high quality standards for their structural integrity, for obvious reasons. Weld points can often pose a critical failure, so these especially must be tested to withstand the high pressure of gas that the container will be used for. Remote laser welding stations typically use multimode, multi-kilowatt fiber lasers…

Overcoming the Challenges of Measuring High Power NIR Lasers

High power laser applications High power laser application has significantly increased in recent years due to new production techniques that enable cheaper manufacturing and operating costs.  Applications of high-power lasers that seemed exotic a few years ago are now considered routine in material processing and micromachining. Such material processing applications as welding, cutting, additive manufacturing,…

Watch: BeamWatch AM Additive Manufacturing

Lightweight, complex mechanical parts can now be “built to order” quickly and automatically, thanks to Additive Manufacturing (AM) technologies. AM involves building up a structure by adding material to it layer by layer, with each layer being a precise cross section of the structure. Originally used for rapid prototyping, AM – now based on various…

Troubleshooting in SLM (Selective Laser Melting) systems with BeamWatch & BeamWatch AM

When asking the SLM manufacturers and users about what they need to know about the laser beam, the first answer we mostly get is, the cross section of the beam profile. But sometimes, this is not the key to solving most problems. The following blog post offers examples of additive manufacturing systems troubleshooting using Ophir’s…
