AILU Free Webinar: Melt pool simulations for welding process optimization
Free online webinar
Thursday 19th September 2024
15:00 – 16:00 BST
Overview
The solutions to common welding defects such as porosity, cracking, and lack of fusion can be difficult to pinpoint when relying solely on experimentation, which provides limited details about process dynamics. CFD can drive experimental analysis through simulations of melting and solidification that address challenges in controlling heat input and keyhole stability, fusing dissimilar metals, and producing desired surface roughness. In this technical webinar we review case studies including laser welding battery casings, busbars, and hairpins, and discuss how FLOW-3D WELD simulations are effectively used to:
- Tune and optimize process parameters in laser welding
- Identify and understand defect formation
- Guide process and material decisions
Who should attend?
- Welding process engineers
- Welding research scientists
- Machine operators
- Metallurgists
- Materials scientists / engineers
- Laser application engineers
Topics to be covered
- Melt pool simulation of laser welding
- Controlling keyhole stability and porosity
- Fusing dissimilar metals
- Laser welding case study: battery casings
- Laser welding case study: busbars
- Laser welding case study: hairpins
What you will learn
- What parameters affect quality when laser welding sensitive components and dissimilar materials
- How melt pool modeling is used to tailor processes for optimal outcomes
- How simulations can compliment experimental work to achieve better welds
As well as a presentation, there will be the opportunity to have questions answered in a Q&A session at the end of the webinar.
The webinar will be recorded and accessible for free via YouTube and Vimeo.

AILU Workshop – High Power and Hybrid Laser Welding
Introduction
Chair: Wojciech Suder (Cranfield University)
High power laser welding together with beam shaping has transformed the quality, speed and gap tolerance of joining thick materials. In addition, sometimes the hybrid laser-arc welding process (HLAW) is used to make single pass welds
with simultaneous laser beam welding and a MIG welding arc (GMAW) to achieve a combination of deep penetration, low heat input and perfect side wall fusion. This can allow alloy welding wires to be used, and deliver much higher throughput than multi-pass multi-layer arc welding. It also minimises distortion.
In parallel with hybrid arc welding, beam shaping is being used to improve the quality of welding, especially in reflective materials like aluminium and copper which are often used in e-mobility applications, for reasons of their high conductivity.
Other research into hybrid ultrasonic and laser welding is showing some benefits in the minimisation of inter-metallics and improvements in weld speed.
With greater laser power, comes the need for greater laser safety considerations. The challenge to build in laser safety when the raw laser beam is above 10 kW is something that the industry is only now starting to get to grips with.
This workshop is aimed at sharing the latest results from researchers and manufacturers in the field of laser welding in the multi-kW regime. As price per watt continues to fall and wall-plug efficiency improves, the inherent viability of laser welding and the ease with which it can be automated makes it more and more the process of choice.
A range of speakers will present and exhibitors offering products to this market will be on hand to share information about their capabilities. Cranfield University is situated conveniently close to the M1 and on the outskirts of Milton Keynes.

Sponsor: SS Laser Solutions
TOPICS FOR THE WEBINAR:
– What is laser welding?
– Differences of laser welding compared to TIG/MIG welding
– Details of handheld laser welding
– Components of handheld laser welding system?
– How to choose the right components for your system?
– Cooling techniques of handheld laser welding machines

WHO SHOULD ATTEND ?:
This webinar is aimed at the sheet metal fabrication industry. If you are currently TIG or MIG welding sheet metal and you are looking to improve the speed and quality of your in-house fabrication, this webinar is for you. Experienced welders are hard to come by, but with Handheld laser welding you can quickly learn to achieve excellent results with a short learning cycle. So, even if you don’t have an experienced welder in-house, this webinar is for you.
SS Laser Solutions are experts in the skill and suppliers of the equipment. Use this webinar to explore whether laser welding is right for your business and to find out about the differences compared to conventional welding. Not all systems are the same and not all suppliers can offer the training, service and hand-holding needed to implement this process in your facility.
Register FREE using the link on this page and the meeting will run on ZOOM on 14 March at 11.00 AM GMT.
If you can’t attend the event live, it is also being recorded and will be available to watch online (YouTube/Vimeo) after the event.
