Choosing the right robotic weld cell for your operation
If a company does much hand welding, it may have loose tolerances on the prints. However, a robot cannot work with these kinds of tolerances. A robot can maintain a good weld only if the parts are held to a tolerance of ± half the weld wire diameter. If this is not determined at... Read more...

Selecting equipment for a robotic welding workcell
Keep the end result—the product that the robotic workcell is turning out —as your primary focus when you select automation equipment. The entire workcell, no one part of it, is crucial for successful integration and an expedient return on investment. A robot is repeatable and makes... Read more...

Laser-integrated robotics for assembly
Recently a cell phone manufacturer set out to be the first to develop an all-aluminum flip-type package for its ultracompact cell phone. Conceptually, the manufacturing seemed feasible, except for the joining of the materials.
Overlooking the Obvious
In the early phase of... Read more...

Al GMAW: CC or CV?
I've read that constant-current (CC) power supplies are preferred for gas metal arc welding (GMAW) aluminum, but when I visit companies that sell welding equipment, they tell me I want a constant-voltage (CV) power supply. What's the real story? Can I use the more common CV power supplies or... Read more...

Loading up on quality, productivity, safety
Like the products it manufactures, CNH Global N.V. has to stay on the move—technologically. The company's Wichita, Kan., facility uses robotic welding to help produce Case- and New Holland-brand skid steer loaders. Powerful yet quick, skid steers can spin on a dime and move heavy... Read more...

Truckin' along through a stamping plant
The earlier cab models were built in a facility that was converted in 1921 to produce the model S truck line, a truck with a 1.5-ton load capacity and a top speed of 30 MPH. The company determined that it could not competitively launch a new line of vehicles without building a new... Read more...

Will a robotic laser system cut it?
Robotic Laser Cutting Systems A typical robotic laser cutting system consists of a servo-controlled, multiaxis mechanical arm that has a laser cutting head mounted to the robot's faceplate. The cutting head has focusing optics for the laser light and often an integral height control... Read more...

Now's the time to AUTOMATE
Object If you looked at metal fabricators' and manufacturers' wish lists, you might see a lot of similarities among them, but you'd also see something the manufacturing industry has in common with all other industries: the need to do more with less. Here's what fabricators are saying: They... Read more...

Is robotic welding right for you?
Recent shortages of trained labor, combined with advances in technology, present a convincing argument to introduce robotic welding to many factory and job shop operations. When a fabricating company already operating at its highest production capacity gets a bigger contract, it is... Read more...

Setting realistic goals for robotic welding projects
Companies interested in purchasing robotic welding equipment often expect robots to solve all their productivity and quality problems. After installation, the actual results often do not meet the end user's high expectations. The natural conclusion is that the robot company dropped the ball;... Read more...

Welding exhaust system components
In the field of automobile exhaust systems, such components as manifolds, pipes, catalytic converters, and mufflers are joined either by the car manufacturer or by a subcontractor to form a subassembly ready for attachment. Today, large numbers of these components are welded with a laser.... Read more...

Robotic arc welding gets smart in real time
Though robots probably are best-known for their ability to accomplish repetitive manufacturing tasks, it's no secret that, by themselves, they are unintelligent and must be told what to do. They are silent, unable to talk over problems with their controller, power sources, the robot in... Read more...

How to Kill a Robotic Project in Five Easy Steps
The same few roadblocks always seem to conspire to either cause a robot project to fail or at least greatly limit its success. Too many manufacturers do things that virtually guarantee that their robots will have serious problems performing as expected. Many of these hindrances have... Read more...

Automated welding for job shops
A robotic welding system represents a significant capital investment for a job shop. The number and diversity of typical products that job shops produce may discourage any interest in automation, primarily because the company cannot figure out how to justify the system purchase and operation....

Designing for successful robotic arc welding automation
This dual robot system uses a large "Ferris Wheel" positioner to give the robots access to the underside of the parts to be welded. Automated robotic arc welding systems are used in all types of manufacturing. They can provide several benefits in certain welding applications. The... Read more...
