What are the benefits of automation with robots?

Robots are the answer to the declining availability of skilled welders and an increase in production demand. One robot can be programmed to hold up to 10,000 programs in its memory, making switchover between parts simple.

Automation also leads to improved quality, consistency, and efficiency. You’ll see every part coming out just like the last, enabling you to keep up with demand and reduce or eliminate rework.

Today’s robots are safe, easy to use, and a valuable part of your production unit.

I’m interested in automation but don’t know what I need. Can you help me?

We’re happy to evaluate if automation is right for your production line and help find the best solution. We’ll visit your plant and conduct an analysis to see how automation could benefit your specific production unit. Contact us to learn more.

Can each robot only produce one part?

Robots can be programmed to hold up to 10,000 programs. Switchover is simple. And contrary to popular belief, you don’t need an immensely high volume of parts to justify automation. The quality and consistency produced over runs of even a few hundred parts can justify the robot’s expense.

I don’t know anything about robotic programming. Is it difficult?

Robotic programming has become more user-friendly than ever. A robot is just a piece of machinery without a skilled programmer behind it. Your welders are the programmers of tomorrow. Our training center provides the skills and hands-on experience to guide welders toward implementing automation at your facility.

OTC DAIHEN talks a lot about reducing spatter. Why?

Spatter is the Hans Gruber of the welding world. Simply put, it’s beads of metal that form around a weld and signal poor weld quality. OTC DAIHEN products are known for reducing or eliminating spatter for a weld that looks good and performs even better.

How much will a robot solution cost?

Many people are surprised when they realize that an automation solution is likely more affordable than they think. It all depends on how many robots you need, the setup, if you require customization, and any number of other variables.
