Pulsed MIG Technology: The Latest Trend in MIG Welding

Definition

The New Pulsed MIG is a state-of-the-art form of welding. It’s a non-contact transfer technique between the electrode and the weld puddle.

What’s in its name?

The process works by shaping a droplet of molten metal at the end of the electrode for every pulse. The appropriate amount of current is mixed to push that droplet across the arc and into the weld puddle. The transfer of droplets happens through the arc, a droplet per “pulse.” Hence, the name.

Advantages of Pulsed MIG

  • It doesn’t produce spatter unlike short circuit.
  • It doesn’t limit welding positions.
  • Its wire use is more efficient than standard ones.
  • You can say goodbye to burn-through thanks to its lower heat input.
  • It’s one of the best welding processes for various applications and metal types.

Modern Pulsed MIG technology and Thin Aluminum

Here are the reasons why pulsed MIG is ideal for welding thin aluminum.

  • You can control heat input. The pulse of top current supplies the good fusion with spray transfer, while the low background current cools off the weld puddle and allows it to slightly freeze.
  • You can control bead profile. You can do this by using “arc control” which adjusts the width of the arc cone, allowing you to customize the bead profile. A narrow bead can help provide good fusion at a joint’s root, while a wider one can help tie in the joint’s sides. If your bead has the right size, there’s no need for over-welding and post-weld grinding.
  • It offers fine travel speeds. Shifting from AC TIG to pulsed MIG can increase travel speeds by around 30% and cut heating input by over 55%.
  • It starts well. Pulsed MIG technology now supplies more energy at the beginning of the weld compared to the standard MIG. This helps establish good fusion and then lowers energy to the normal limit for maximum welding features.
  • It ends well. New pulsed MIG tech also does a good job ending the weld by ramping down to a cooler welding variable to fill in the crater. It also has the ability to modify the amount of ramping to make up for the different heat dissipation characteristics of carbon steel, stainless steel, and of course, aluminum.

All this information makes it worthy to check out this new technology. However, if you need to weld thicker aluminum or you’d rather wait for this modern technology to fully develop, you can check my favorite MIG welders for personal use instead.

The Downsides of Too Much Internet

The internet is a great thing and has proven itself to be one of the modern world’s most influential innovations. And as the technology continues to develop and become more accessible, a growing number of people are living their lives online. Whether as a tool for work or personal entertainment and communication, online platforms like social media sites have become an important part of many people’s daily life.

But greater connectivity comes with its share of disadvantages. Uncontrolled use leads to more time spent online which often leaves little time for real life connections. Concerns about social networking ruining relationships have been increasing of late. And the many images that show people focused on their mobile phone screens even in the company of others seem to suggest that phone and internet addiction may be real.

Spending more time online or losing track of time when using the internet is a common problem. It may be unplanned like clicking a notification about an incoming email, which could lead to checking other emails or social media accounts to see the latest news or information.

All the extra time spent on non-essential things online could also lead to loss of productivity. The internet becomes a distraction that leads to neglect of more important things to do. And the inability to self-regulate online use or the unwillingness to unplug more can get in the way of other more crucial tasks. The internet may be a good thing filled with amazing possibilities. But only when users stay in control and use it in moderation.

Things Robots Can Do to Improve Daily Life

The future is here judging by the number of robots you see the robotics field is working on. Many robots including some prototypes have been unrolled. This may have sent ripples to STEM people, but it has hardly been an everyday topic of discussion for the rest of us. But it is interesting to note how robots are becoming more well-designed, intelligent, and efficient. These are among the many other characteristics that leave many of us laymen in awe.

Robots have been depicted in books and films in many different ways. They can be quite disturbing and scary as some of these stories suggest. For this reason, some people are wary of the idea while others are fairly ambivalent given the lack of knowledge and information. But imagine if you wake up one day with robots suddenly becoming a daily part of your life. How do you think that would make you feel? If robots turn out as well as many of their creators are envisioning them to be right now, they can play a big role in improving people’s daily life.

Robots providing entertainment

The robots that have been entertaining people who read books or watch films about them. But they have leapt out of the pages and the big screens into real life. In the past years, there have been entertainment robots that delighted people in different parts of the world. There was even a buzz about robot dogs. The Sony robot dog Aibo was designed as a robotic pet and has became popular among many for their entertainment value. This entertainment robot is just one of the many that have been rolled out to the public albeit with not much fanfare as other popular crazes we have seen in recent years.

Robots doing dangerous work

Curiosity, the famous NASA rover, has been in Mars for almost four years now. It successfully landed on the planet in August 2012. It has since done a lot of work that provide insights scientists and engineers need for their research. Curiosity is just an example of robot that can do dangerous and what for now may be impossible work for humans to do. Imagine what other extremely risky jobs robots can do that could keep people away from harm.

Robots as nannies or caregivers

Japan has been deep into research and innovation involving robot caregivers. One company started rolling out robot nannies in 2015 and others have built various prototypes several years ago. There have been features and stories showing robot caregivers doing their work with the elderly and children in certain parts of Japan.
