Switching from manual welding to a welding robot offers multiple advantages:
Welding Robots are Cheaper - Robots are a one-time purchase. After factoring in all the money spent on the equipment cost and the hourly rate of a manual welder companies typically find that robots are a cheaper alternative for welding needs. To figure out the amount of money you can save annually by using a robotic system use our ROI calculator.
Robots Offer Greater Accuracy - Robots, unlike humans, can be programmed to execute the same weld repeatedly without even slight alteration. They are capable of great precision. Robots are less likely to make mistakes. This in turn leads to a more reliable, high-quality product.
Welding Robots Up Production - Robots are able to work 24 hours a day 7 days a week with no breaks, which means an increase in production. With welding robots, cycle times are often much shorter, leading to more throughput.
Robots Conserve Resources - Robots won't waste your time or materials. Their programmed precision makes them less likely to waste products because of faulty welding. They work quickly without taking breaks, saving valuable hours and cost.
Welding Robots Create a Safer Workplace - Welding can be hazardous to one's health. Robots are oblivious and protected against welding dangers like smoke, fire, fumes - taking humans out of potential danger.
Robots Bring Flexibility - The large work envelopes of welding robots allow for better part accessibility.
Unless specified otherwise, it is the customer's responsibility to arrange and pay for a confined air-ride box truck with an entrance no less than 110" tall and a width that can accommodate a forklift for loading and unloading the robot.
Extra large systems that need flatbed trucking must be weatherproofed prior to shipping with a heavy-duty plastic tarp. Extra charges may apply with this option.

Welding robots have their own set of maintenance needs. Robotic welding systems have to keep everything regulated correctly - torch angle, wire feed, gas flow. As with most equipment, when it comes to welding robots, a little maintenance goes a long way.
RobotWorx recommends paying attention to these items for the best results:
Proper connection of welding leads: Positive from power source to wire feeder and negative from power source to work piece, table, and fixture.
Wire feeder: The wire drive roll needs to have the proper tension and the rollers must be the proper size.
Welding Gun: Check the condition of torch contact tips, nozzles, and make sure there is the right amount of gas flowing through the gun.
Robot Tool Center Point (TCP): Make sure you've programmed this point correctly. It controls the torch's position and makes it possible for the robot to perform the proper movements.
No, this should not be a problem. Rebuilt robots retain the same configuration and capabilities of the original robot and only have to comply with the standards in effect on the original manufacture date. If you actually 'remanufacture', i.e. upgrade the robot, then you will have to comply with the 1999 edition of the standard.
Robot welds are extremely accurate and consistent. This welding accuracy leads to better product quality and less wasted material while typically increasing throughput and cycle speed.
Robot welds are more accurate because...
They are Precise - Welding robots perform with exceptional precision of movement.
They Offer Top Repeatability - Welding robots are programmed to perform the same job repeatedly, without any alteration. This eliminates welding mistakes while increasing throughput.
Automation Equals Accuracy - Robotic welding is a programmed, regulated process. Unlike manual welding where the weld quality is determined by the worker's skill, robotic welding is always the same. With proper programming, robots will help you avoid waste and boost product consistency.
The Robotic Industries Association (RIA) standard is the ANSI/RIA R15.06-1999, Safety Requirements for Industrial Robots and Robot Systems.
The ANSI/RIA is not a law but a voluntary American National Standard. Adhering to it is not so much a legal issue as it is a compliance issue. As more and more users require compliance with the standard in their contract specifications, you may be obligated to comply with the standard. More contracts will be let this way, since the user is required to comply with OSHA directives that include voluntary standards by reference.
Welding robots are equipped with internal and external safety features. Light curtains, safety stops, walls, weight-sensitive mats, and shielding protect the robot and the robot operator. Other safety features are programmed into the robot. Vision peripherals can also work as safety devices.
Furthermore, welding robots provide a safe alternative to manual welding. Unlike their human counterparts, welding robots don't run the risk of electric shock, severe burns, eye damage, etc.
Instead, they remove workers from the danger zone to the safety of operator's positions. They are oblivious to the bright light, sparks, chemical fumes, and extreme heat caused by welding applications.
Robot welding systems are considered refurbished once they have passed through RobotWorx' comprehensive 168-point reconditioning process.
Each used robot welding system is thoroughly cleaned, reworked, tested, and given a fresh coat of paint. Our robot service department pays close attention to every aspect of robot welding systems by performing the following:
* Harmonic drive and belt assembly inspection/cleaning/lubrication and replacement as needed.
* Battery replacement
* Wire harness inspection
* Bearing check and lubrication
* Repeatability and performance testing
While Metal Inert Gas (MIG) and Tungsten Inert Gas (TIG) are both shielded arc welding applications, they are very different from one another. MIG welds are created with a consumable electrode, while TIG welds are created with a non-consumable electrode. TIG welding typically includes filler metal as well.
TIG and MIG arc welding can both be automated. However, TIG is a more complicated process so the equipment is more expensive and difficult to set-up. Find out more about the pros and cons of MIG vs. TIG.
Turnkey integration gets its name from being all-inclusive and production-ready.
Robot workcells are turnkey integration systems because they require little installation and have every necessary element: robot, safety, tooling, etc. Turn a key or flip a switch, and presto - you're automated!
Interested in a robotic turnkey integration system for your facility? RobotWorx is a turnkey integration expert. We build custom turnkey workcells to answer specific application needs. Avoid delays and costly mistakes when you buy a turnkey integration system.
Unless welding is performed with a very low current, a concave dip, called a crater occurs at the end of a weldment.
This crater results from the force of the arc and the contraction of melted metal when it cools and solidifies. The size of each crater relates directly to the welding current. Craters are not desirable because they cause a welding defect due to slag wrapping.
Crater welding is one method used to fill craters. It requires regular welding current. There are control sequences that allow you to switch to a crater filler current.
A robot can only work in the area in which it can move. This area is called the work envelope. The work envelope is determined by how far the robot's arm can reach and how flexible the robot is. The more reach and flexibility a robot has, the larger the work envelope will be.
Axes - The number of axes a robot has define its flexibility level. The typical industrial robot has six axes of movement.
Length of arm segments - The robot's axes link arm segments which each vary in length. The length of the arms combined with the capabilities of each axis determine a robot's reach.
Placement - Robots have different mounting options. Their work envelopes vary in scope depending on whether they are shelf, ceiling, wall, or floor mounted. Some robots can be mounted to tracks or gantry systems, which further expands their work envelopes.
Construction - A robot's strength effects its work space. Robots have different payload capacities which in turn determine the type of EOAT that can be attached.
Gas Metal Arc Welding is a welding method more commonly referred to as GMAW or MIG welding.
Typically used in the automotive and sheet metal industries, GMAW can be an automatic or semi-automatic process. GMAW provides high quality welds at a low cost to the manufacturer.
This arc welding application feeds a GMAW metal consumable electrode and shielding gas through the welding gun. An electrical current travels down the electrode and strikes the arc between the metal being welded and the wire electrode.
The advantages of GMAW include:
Speed - GMAW is a fast welding application
User-friendly - This welding approach is easy to set up and implement.
Cheap - GMAW equipment tends to be more affordable and more available than other welding equipment.
GMAW is used on these materials:
Steel, Aluminum, Copper, Nickel, Magnesium and other non-ferrous materials.
ROI stands for "Return on Investment". This is the amount your company will save by incorporating robots. A robotic system typically produces the same output as 4 welders.
The annual savings (ROI) can be calculated as follows:
ROI = [(x + y) * 4 - z] * t
x = Hourly Rate of Welder
y = Equipment Cost Per Hour
z = Robotic System Cost Per Hour
t = 2080 Hours Per Year
Prototype tooling as basic part fixturing, as well as the use of manual clamping and rigid steel framing that is fabricated from a customer's parts.
Prototype tooling provides a concept of what the production tooling is meant to be. It is not meant for production tooling. When the prototype tooling is tried out, final tooling could be quoted to you and provided.
Prototype tooling does not include: part presence sensors, tooling design drawings or pneumatic clamping and isn't subjected to a customer's specifications or original design. Prototype tooling demonstrates the correct way to weld the part and also shows how tooling can be instituted at low cost to the customer.
