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.

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.

Application labs - invest time up front to ensure success

Posted by Mark Boyle on Tue, May 02, 2017 @ 12:30 PM

Application engineers are a funny breed. They get their kicks from solving real-life manufacturing challenges – and the thornier the better! They like to get up close and personal with an application and help those having trouble to find the right way to weld, mark, cut, bond or machine a part. They also get a great deal of satisfaction from fixing a process that is taking too much time and affecting output (and the bottom line), one that results in unnecessary scrap or one that is out of limits. If the solution doesn’t work out the first time, they stick with it until they develop a one that works.

Material processing solutions for manufacturing – one size does not fit all

Posted by Barbara Kuntz on Tue, Jul 12, 2016 @ 12:30 PM

You heard it here first: there is no single materials processing technology that fits all applications. Manufacturers looking for a robust, production-ready solution must follow a rigorous process to determine the best choice of equipment. There are no short cuts or magic wands – you have to carefully review process feasibility and part design to maximize production reliability. The evaluation must also consider overall system needs.

Why weld monitoring? 3 Reasons: Analysis – Stability - Yield

Posted by Loren McLellan on Tue, Jun 17, 2014 @ 02:06 PM

Resistance spot welding monitors and checkers measure the electrical and mechanical aspects of the welding process; they analyze weld quality enabling the user to make adjustments and improvements resulting in process stability, and, ultimately, improved yields.  Here’s a quick look at the three most important reasons to consider adding a weld monitor or weld checker to your resistance welding line:

Battery pack welding: which technology for your job?

Posted by Geoff Shannon on Thu, Feb 06, 2014 @ 10:46 AM

"Ugh - my battery just died!" "Can I use your charger?" "Mind if I recharge my phone?"  Batteries are everywhere, and we've become increasingly dependent on them in many aspects of our daily lives: portable electronic devices, cordless power tools, energy storage, and hybrid and EV cars. Thus, the demand to manufacture batteries that meet or exceed quality and production requirements for these products, is great.

Resistance spot welding, micro TIG welding, and laser welding processes all enable high quality volume production.  The selection of one technology over another is usually made based on the application's specific requirements and the alignment of the technology to these needs.

Resistance welding trouble shooting: 7 simple steps

Posted by Marty Mewborne on Thu, May 30, 2013 @ 08:18 PM

You've been successfully running the same resistance spot welding program for days - months - years when all of a sudden it stopped working.  What do you do?  Where should you start?  When troubleshooting a problem with your resistance welding process, we've learned that it's best to start with the materials and move back toward the power supply.  Troubleshoot using 7 simple steps, in this order:

Battery Pack Welding: Better Performance and Higher Currents

Posted by Marty Mewborne on Thu, Mar 28, 2013 @ 08:00 AM

Battery tabs seem to have been getting thicker and more conductive over the last several years, as customers seek better performance and higher currents from their battery packs. These thicker battery tabs are usually made of nickel, but nickel-plated copper tabs are gaining in popularity due to their higher conductivity.  We’ve had success welding the thicker nickel tabs, but have found the nickel-plated copper to be very difficult to weld.  How to overcome that?  Add slots and projections to the tab design to focus the current and minimize current shunting.  Welding success also depends, in part, on the battery itself; those with thick caps can easily handle the high force and current needed to weld the thicker tabs.  If the battery caps are too thin, however, they may get deformed or blown through.

Innovations on Parade – New Fiber Laser Welder at MD&M West

Posted by Barbara Kuntz on Tue, Feb 12, 2013 @ 03:08 PM

The Medical Design & Manufacturing (MD&M) West exposition and conference is the place to be this week if you want to see the latest innovations in equipment and systems for medical device manufacturing. Despite all the doom and gloom you hear about the manufacturing sector, the medical device industry has been on fire for the last decade, and shows no signs of let up.  Innovations in technology are on the rise as everyone is looking to do things smaller, faster, and more reliably. I like to stroll the aisles looking for what’s 'just out.' If you do too, drop by Miyachi Unitek’s booth - #3051.

AC, DC, CD or HF: Which Spot Welding Power Supply Should I Use?

Posted by Marty Mewborne on Tue, Nov 20, 2012 @ 08:00 AM

I recently posted a blog about closed loop welders and how you can get the most out of using them, and it occurred to me that some of you may not be familiar with the different resistance spot welding power supply technologies, how they work, and what they can be used for. So here is a short description of the four different types, including both closed loop and open loop designs.
