We’ve touched on some pretty heady stuff in the past couple of blogs, so maybe something more straightforward is in order. Here goes:
Why use laser welding?
Contaminants in your weld? Here's how to prevent them
| Sandwiches don't mix well with welding. |
I mentioned in blog 4 that contamination is a topic in itself. Well, why not follow that train of thought?
Anything and everything that is not the “stuff” being welded is a potential contaminant. Whether it be oil from machining, paper fibers, soapy water from a wash cycle, a sliver of plastic from your expensive non-marring table top, or even brown mustard from that London broil sandwich you had for lunch, these are going to put something unexpected into your end product.
Common weld defects and their causes: porosity
Alright, now that you’ve read the “Misconceptions About Welding” blogs, you want to know what else you might not know about welding, huh? So, let’s talk defects. In this blog we’ll discuss porosity.
I like to talk about porosity more than other weld defects because even though there are many contributing factors to it, at the end of the day it is always (did I use an absolute?) trapped gas in the solidifying weld.
Welding Myths Part 3: A weld is never as strong as the parent material
To go along with the last post on welding myths and non-weldable materials, I also often get grudging calls from a designer who has been “forced” to add a weld to a design.
Customer: “How much do I have to overdesign this part for this weld?”
Me: “Why do you want to overdesign?”
Customer: “Well, the weld is going to weaken the part! I need to beef it up to compensate.”
New leadership series helps women advance their STEM careers
If you’re a woman in STEM (science, technology, engineering, math), how do you navigate a career with few role models or mentors?
According to the U.S. Department of Commerce, women are 50 percent of the overall workforce but only 24 percent of the STEM workforce. Moreover, 50 percent of women in STEM careers drop out in the first 10 years.
Welding Myths Part 2: If it’s metal, I can weld it
This misconception about welding comes up far more often than I’d like. An engineer calls in a rush to get a prototype stainless steel part welded. To save time and cost, he had the parts made from free machining material. Frantic on the phone, the conversation generally goes something like this:
Welding Myths Part 1: Welding will distort my part
There are lots of misconceptions about welding that keep it off a designer’s list of preferred joining methods. Over a couple of blog posts, I’ll debunk a few of the most common myths and explain why they aren’t accurate.
I hear this one all the time: “Welding is going to distort my part so that it will be unusable!”
Joining Technologies named one of Murphy’s Monday Manufacturers
U.S. Sen. Christopher Murphy of Connecticut has named Joining Technologies in East Granby, CT as one of Murphy’s Monday Manufacturers.
Murphy’s Monday Manufacturers “recognize the best and brightest of manufacturing in our state,” the Senator said.
Go On. Give Us a Good Challenge!
Got a project with technically challenging requirements? That’s just the type of project Joining Technologies specializes in.
For example, JT won a contract from the U.S. Naval Air Systems Command to design, manufacture and deliver a series of on-board battery power systems.
These systems support the Naval Air Warfare Center Aircraft Division. Joining Technologies leveraged its expertise in metallurgy, laser welding, machining and supply chain management to deliver the first prototypes to the Navy in 2016.
