Drive EV Battery Efficiency with Laser Welding

Posted by Mark Boyle on Fri, Dec 20, 2019 @ 02:17 PM

Enhanced performance of EV batteries is a major factor in the steady increase in electric vehicle sales. And better performance stems, in part, from recent developments in laser welding of dissimilar metals which increases efficiency by increasing energy storage, reducing size, and preserving reliability. It’s a fact that welding a less resistive metal to the standard stainless-steel terminal of a lithium ion battery can reduce resistance and improve battery efficiency. Traditional resistance spot welding, however, can’t effectively join highly-conductive dissimilar metals like copper and aluminum because the resultant intermetallic mix is brittle. But lasers CAN do the job with surprising results!

Tips for generating clear and effective motion programs using Delta motion software

Posted by Brayden DeVito on Thu, Jun 13, 2019 @ 01:08 PM

Delta motion control software is used to program motion on Amada Miyachi laser welding systems. Many of the terms are standard G&M codes, which can be applied to other CNC style motion programming. Here are a few tips for using the software to program nearly every type of weld joint configuration. In this post, we are just hitting the highlights to get you started on the right “path.” Full instructions on essentials for each configuration type can be found in Quick Start Guide to Programming in Delta Motion.

Ultra-Short Pulse Lasers Are Great Tools for Processing Plastics for Medical Devices

Posted by Geoff Shannon on Tue, Feb 27, 2018 @ 12:35 PM

In the past few years, we have found that ultra-short pulse (USP) lasers are being used more and more for medical device manufacturing – from stents and catheters, to wire stripping and balloon texturing. The level of quality and dimensional accuracy needed fits well with the USP lasers, which do a great job of drilling, cutting, skiving, texturing and machining both plastic and metal-plastic combinations.

Looking for ways to improve your assembly process? - Try 6S

Posted by Michael Vest on Tue, Feb 20, 2018 @ 12:35 PM

I would say that most, if not all, manufacturers are continuously looking for ways to reduce waste and improve efficiency. If that describes you, I have a suggestion – adopt the 6S workplace organization method.

Laser System Teach Mode: Compensating for Part Variation

Posted by Mark Boyle on Fri, Nov 17, 2017 @ 12:37 AM

Today’s post is about using “teach mode,” a fairly standard software function that enables a laser operator to customize tool paths without having to write complex code. This feature aids the operator when there is significant part to part tolerance issues. Here’s an example of how teach mode works for a complex tool path:

Projection Welding of Fasteners to Hot Boron Stamped Components

Posted by Bob Kollins on Fri, Sep 22, 2017 @ 09:00 AM

Projection welding of fasteners to hot boron stamped components

Automotive component assemblies often incorporate projection welding of fasteners. And more and more manufacturers are using hot stamped boron steel, like Usibor®, resulting in lighter weight components with increased tensile strength (up to 1500 megapascals (MPa). This helps them meet regulatory requirements while maintaining 5-star safety ratings.

Exposing high school students to engineering career paths

Posted by Mark Boyle on Thu, Aug 03, 2017 @ 08:46 AM

AMADA MIYACHI AMERICA strongly believes in serving the community and especially looks for ways to engage with students to encourage and develop the next generation of engineers. We have an active, thriving partnership with our local colleges and universities and provide technical internships to students in the engineering disciplines.

One fun event we recently hosted was a tour of the Monrovia, California facility by high school students from the San Gabriel Valley Economic Partnership. The partnership includes an education and workforce development initiative focused on a regional consortium of the Duarte, Azusa, Charter Oaks, and Monrovia school districts.

Spot welding: improve quality and reduce cost with inverters

Posted by Mark Boyle on Thu, Jun 29, 2017 @ 12:45 PM

Successful manufacturers constantly look for ways to improve quality while reducing costs. That’s why many are looking beyond conventional spot welding technology for something to help them achieve their cost reduction goals. Resistance welding traditionally utilizes alternating current (AC); however, this technology has limitations in the control of the output energy. Resistance welding with direct current (DC) using inverter technology, however, dramatically improves weld process control through closed loop feedback. This provides a consistent output, in turn lowering scrap and increasing production yield.

Ultrafast laser systems offer great promise as a manufacturing tool

Posted by Geoff Shannon on Tue, Jun 27, 2017 @ 12:30 PM

Owing to their very short pulse durations - sometimes less than the target material's conduction time - and very high peak powers, ultrafast (femtosecond and picosecond) laser systems offer unique material processing possibilities such as “cold machining” of parts with no/negligible heat affected zone. In fact, this short pulse width/high peak power, combination enables processing capability of almost any material, including metal, plastics, ceramics or glass.

Nanosecond laser micro welding: the possibilities!

Posted by Geoff Shannon on Tue, May 23, 2017 @ 12:30 PM

The nanosecond fiber laser is the most recent addition to AMADA MIYACHI's broad portfolio of micro welding solutions. Its output parameters are a bit different than other laser welding sources like pulsed Nd:YAG ,quasi-continuous-wave (QCW) fiber and the CW fiber laser. As the name suggests, the nanosecond fiber laser’s pulse widths are in the nanosecond range - under 250 nanoseconds (ns) - with pulse energies around 1 millijoule (mJ).
