FABTECH is definitely one of our favorite shows. People are really excited about seeing the latest and greatest metal forming, fabricating, welding, and finishing solutions – and we like being part of the atmosphere. This year we have several people giving presentations and we’d really like to encourage you to drop in one one (or all) of them!
Mark Rodighiero and I will both be presenting at the AWF100-New- Laser Welding for Today’s Fabricator Workshop (I), which takes place on Thursday, November 17, 2016 in room N219-220 from 8:00 AM to 12:30 PM.
Mark’s System Overview for Laser Welding is a great starting point to learn about the key elements to a laser welding system and how they work together. Mark is going to give a really helpful and informative overview of the laser itself, how the laser is delivered to the workstation, the laser focusing optics, and how weld motion is executed. He’ll also cover control software, vision, tooling, and process monitoring. He’s going to offer valuable insight into systems and system requirements typically used in a number of industries, including automotive, medical and battery manufacturing.
I am going to present Material Selection for Laser Welding. As with any welding application, laser welding applications start with the material selection – selecting a material or material combination that provides optimized part functionality while at the same time being easy to weld and providing a reliable manufacturing process. I’m going to cover several material types, including carbon steel, stainless steel, nickel alloys, aluminum alloys, copper alloys, titanium, and dissimilar metal welding. I plan to provide some guidelines for each material type, along with welding examples, showing both good welds and weld defects. The talk will also cover the effect of platings on weld quality. Be sure to check out the unique prospects for dissimilar materials welding, particularly for thin gage materials. I plan on giving showing plenty of examples for copper/steel, aluminum/steel and some others.
Last, but definitely not least, Mark Boyle is going to present Laser Welding Dissimilar Materials for Tab to Terminal Joining in Session 10: Dissimilar Joining Applications which will take place on Friday, November 18, 2016 in room N238-N242 at 9:20 AM.
Mark has a lot to say about the issues involved with welding dissimilar materials, which has been a key challenge for battery pack manufacturers looking to weld various combinations of copper, aluminum and steel to optimize pack manufacture. The concern with these and other material combinations is the formation of brittle intermetallics. Time on part is a key factor in the growth of intermetallics, so Mark has been investigating welding using a single mode laser to maximize weld speed or minimize pulse energy. He found that the single mode fiber laser’s results and dissimilar material welding capability has gone well beyond expectations. It’s a big factor in improving the viability of a number of interesting material combinations. Be sure to attend the presentation to see Mark highlight the welding mechanism of both high speed and low energy, and show various weldable material combinations, with a specific focus on aluminum to steel.
