What is robotic TIG welding?
Robotic TIG welding combines Tungsten Inert Gas (TIG) welding with the consistency, efficiency, and productivity of robotic automation — a TIG welding robot provides continuous operation capabilities, enabling complex welds with high accuracy levels.
Key components of a robotic TIG welding system
Setting up a robotic TIG welding system involves several elements working together.
Let’s break down the main components:
- Robot arm and controller: This duo handles the precise movements and positioning that are essential for high-quality welds.
- TIG torch and power source: The torch delivers the arc while the power source provides the juice, giving you control over heat input and weld characteristics.
- Tungsten electrode: Typically non-consumable, this is the core of the TIG torch, responsible for creating the arc that melts the metal.
- Shielding gas system: This system protects the weld pool from contamination, often using argon or a specialized gas mixture.
- Software for programming and integration: This software allows you to program weld paths, fine-tune parameters, and integrate your welding system with other production processes.
Also, automated TIG welding machine systems are available in various configurations, each suited to specific production needs.
Types of TIG welding systems
Let's explore the main types you'll encounter in modern manufacturing.
Standalone robotic cells
These self-contained units are perfect for dedicated TIG welding jobs. So long as you keep these maintained, set up, and programmed correctly, you’ll profit from their efficiency. It’s pretty much an always-there robot cell, ready to tackle jobs when you need it to.
Integrated multi-process systems
Flexibility is the name of the game here. These setups can switch between TIG and other welding methods, adapting to diverse production requirements without missing a beat.
Collaborative robotic (cobot) TIG welding
Here’s when a collaborative robot works side by side with human welders. Cobots bring automation benefits while maintaining human oversight, which is ideal for complex or variable welding projects.
Pros and Cons of Robotic TIG Welding: An outline
Before we get into the details, we’ve outlined the pros and cons of robotic TIG welding below.
Benefits of robot TIG welding
Robot TIG welding brings some serious perks to the table. Let’s take a look at the benefits of robotic welding:
Jaw-droppingly precise
Robot TIG welding makes things much more consistent. This kind of precision means fewer flaws and less rework. Moreover, this consistency is especially important with the intricate welds often required by TIG processes.
Cranking up the production volume
With a robotic system, you can keep the welding torch firing nearly non-stop. There will be no breaks, no shift changes — except for scheduled breaks, of course.
Your throughput can significantly increase, allowing for faster project completion, although remember, regular maintenance and occasional repairs are necessary.
Keeping your welders safe
Modern robotic TIG systems prioritize safety by taking on the physically demanding aspects of TIG welding. This means a safer work environment, less strain on your human welders, and reduced risk of injuries. Plus, it frees up your skilled staff to focus on more complex jobs and value-added tasks that robots can't handle while optimizing the implementation process overall.
Common challenges in TIG robotic welding operations
TIG robotic welding can be a game-changer for many operations, but it's not without its hurdles. Let’s take a look at some common challenges:
Weld quality mishaps
Even with robots, achieving consistent weld quality can be tricky. Factors like material variations and environmental conditions can ruin your efforts.
Talent crunch
The welding industry is facing a serious skills gap. Finding and retaining skilled operators who can program and maintain robotic TIG systems is becoming increasingly difficult.
Precision demands
TIG welding often requires extreme precision, especially in industries like aerospace or medical device manufacturing. Meeting these exacting standards with robotic systems can be a tall order.
Applications of robotic TIG welding
TIG welding is frequently used in the aerospace, automotive, medical, and manufacturing industries. These industries rely on TIG welding because it’s all about precision, clean welds, and handling tricky materials — and robots are making it easier than ever.
- Aerospace: When you’re welding aircraft components, there’s no room for error. Robots handle heat-sensitive metals like titanium without warping or major flaws.
- Automotive: From exhaust systems to chassis components, robotic TIG welding keeps car production fast, consistent, and high-quality.
- Medical device manufacturing: Surgical tools and implants need perfectly clean welds. Robots eliminate contamination risks and make sure you get long-term durability.
- Industrial fabrication: For stainless steel piping, pressure vessels, and other heavy-duty builds, robotic TIG welding delivers strong, corrosion-resistant welds that hold up under pressure.
Installing a TIG welding robot in your fabrication shop
We’ve summarized the TIG welding installation process below.
Choosing and installing a robot is the most important part of any TIG welding automation endeavor. To get set up, here are the steps in detail:
Step 1
First, choose a robot model that can handle the materials, welding positions, and production volumes you need. Many manufacturers offer 6-axis robots specifically designed for welding, with the durability to withstand high heat for extended periods and the precision to produce clean welds. Look for one with a reach of at least 1 meter so it has an ample range of motion.
Step 2
Your robotic arm will need to be equipped with an “end effector.” This is the “hand” or tool of the robot arm — so make sure you choose a robotic arm with a high enough payload to lift the end effector. This is particularly important with welding since your robot must also handle heavy cables. We recommend at least 10 to 15 kg in payload capacity for a TIG welding robot.
Step 3
Next, select a welding tool end effector for your robot. In most cases, your robot arm’s manufacturer can recommend the best match. Remember, you’ll still need a separate welding power source and wire feeder to match your end effector — the robot arm will be powered separately.
Step 4
Then install the robot, power source, and wire feeder on a sturdy platform or frame near your welding stations.
Step 5
With all the gear in place, you'll need to program the robot's control software with the specific welding parameters for your parts. This includes details like weld sequence, travel speed, amperage, and gas flow.
Training your human welders to work alongside TIG welding robots
Now, you’ll need to ensure your experienced human welders are best prepared to work safely and efficiently with their new automated colleagues.
Let’s take a look:
- Hold information sessions to educate welders about the robots: This will entail addressing any concerns about job security or safety. While most industry professionals are well aware of the labor shortages pressuring fab shops, clear details on what robots will and will not be used for can help put your welder’s minds at ease.
Always emphasize and explain how the robots will handle repetitive jobs, freeing up humans for more complex, precision welding.
- Provide hands-on training for operating and programming the robots: Even though the robots will do most of the welding autonomously, welders should understand how to start, stop, and adjust the robots if needed. Allow plenty of time for welders to get comfortable working around the active robots.
- Establish clear procedures for human-robot collaboration: For example, determine how welders will load and unload parts from the robot work area, how to properly hand off an in-progress weld to a robot, how welders and robots will share a welding cell, etc. Practice and revise these procedures to ensure maximum efficiency and safety.
- Start with a pilot program using a limited number of robots and your most experienced or adaptable welders: As they become proficient in working together, you can scale up to more robots and welders. Continually solicit feedback to improve the program.
- Provide ongoing support and additional training as needed: Welding technology and robot capabilities are constantly evolving, so make continued education a priority for your welding staff. With the right training and experience, your human welders and TIG welding robots can work together as an automated, productive team. Some integrators like THG automation can help here.
Robotic TIG welding: Cost-benefit analysis
While TIG welding robots offer outstanding benefits, they do represent a pretty sizable investment. You must carefully weigh upfront and ongoing expenses to make an informed decision.
Here's what to keep in mind:
- The initial investment: The robotic arm itself is a major cost factor. Expect prices for a suitable six-axis arm to typically range from around $30,000 to $100,000 or more. This depends on capabilities like payload and reach.
Additional essential components include the specialized TIG power source, torch, shielding gas supply, and any required enclosures. Combined, a basic TIG robotic welding cell can cost between $75,000 and $200,000+.
- Don't overlook the ongoing expenses: Your TIG robot will consume tungsten electrodes, shielding gas, and electricity. Also, factor in routine maintenance, replacement parts, and potential software updates for optimal performance. It's wise to budget approximately 10 to 15% of the purchase price annually for these operational costs.
- Training! Your team will need training to safely and effectively program, operate, and maintain the new robotic TIG system. Include these training costs in your overall budgetary calculations.
Bottom line: Robotic TIG welding offers a powerful way to elevate your fab shop's quality, productivity, and overall efficiency.
