Welding

Material joining by the use of power sources, gases, nozzles, tips, wire, filler metals, manual and automated processes, robots, jigs, turntables, consumables and other equipment assisted by Computer Aided Design (CAD), Computer Aided Manufacturing (CAM) and Computer Numerical Control (CNC).

Using Metal-Cored Wire with Pulsed MIG to Weld Galvanized Steel

High strength galvanized steel is an excellent material to help automotive manufacturers build lighter-weight vehicles, but it can present some challenges that make it difficult to weld.

Using Welding Intelligence Designed for Pipe Fabrication

Pipe shops now use electronic dashboards to replace pieces of paper that once traveled with spool joints across the floor and through the weld testing process.
Engine Driven Welders

Next Generation Speed Governing Technology

Numerous benefits can be gained from improved fuel efficiency and reduced noise when using new welder/generators with speed-regulating technology.
Filler Metals/Electrodes

Considerations When Selecting a Filler Metal (Part Two)

Although the effect of various elements in filler metals can be rather complex, a review of their general properties can also help welding operators determine which filler metal is ideal for the job. It is important to consider the properties needed in a completed weld when making the filler metal selection.
Fume Extraction Systems

The Right Filter Makes a Difference in Weld Fume Management

Removing the fumes from the area is only the beginning of the process. How you filter the fume is just as critical to achieve successful results.
Gases

Clearing the Air in Gas Delivery

MIG and TIG welding, plasma cutting, laser cutting or welding all require compressed gases. How these gases are stored, handled and used will determine the extent that the overall cost of these gas products impacts your bottom line. The correct gas delivery system will provide the most economical and efficient results to complement any of these applications – and the normal starting point for all of them is a cylinder of gas and a regulator.

Electron Beam Welding vs. Laser Welding

A comparison of the two processes by application and cost.
MIG Welders

Industry Standards Are Evolving Faster Than Ever

For auto body shops or tractor repair facilities to effectively keep up with the new demands being driven by fuel economy mandates and remain profitable, they must invest in easy to use equipment that is capable of welding both steel and aluminum.
Plasma Cutters

Beware of Bad Bargains

Watch out for artificially low prices on aftermarket plasma torch consumable parts. Before you buy, it is important to be aware of a few of the poor performance issues and risk of torch damage that your shop will experience if you purchase imitation consumables.

Blueprint for the Future

Fabricators must continually explore new technologies that will grow along with their operations to help them stay competitive, profitable, productive, and ahead of the curve so they are prepared for the demands of the future. 
Resistance Welders

Seamlessly Joined? Comparing Cast and Soldered Electrodes for Spot Welding

Cavities in the solder between the electrode and the shaft have a negative impact on the quality of the resistance weld. Plansee explains why anyone wishing to avoid cavities should use cast electrodes rather than soldered electrodes.
TIG Welders

The Passion Inside Out Back

A father-son boat repair and fabrication shop finds power, flexibility and quality with a TIG welder that can deal with the unique challenges of their business.

From Selection to Storage: The Basics of Common Aluminum Filler Metals

In order to gain the best results when welding aluminum, Tim Hensley of Hobart Brothershere are the reasons why and how it is critical to select the correct filler metal and carefully follow the proper storage and handling procedures for these products.
Welding Guns/Torches

Waste Not, Want Not

Planned downtime for preventive maintenance in the welding operation is not time wasted. Here are some crucial maintenance tips that help optimize MIG gun performance, keep production flowing smoothly and avoid unplanned downtime. 
Welding Helmets

Sight for Sore Eyes

Clearly, the right auto-darkening helmet boosts productivity and quality. Here's how optical clarity defines helmet performance by providing users with vital eye protection and the ability to fully see the work . . . and that’s when work is done best.

Gas-Shielded Flux-Cored Wires Lower Manganese Emissions Even More

FabCO Element 71C and FabCO Element 71M wires help address increasingly stringent environmental regulations and recommendations. In addition to low manganese levels, both the Element 71C and Element 71M wires offer enhanced out-of-position capabilities, making it easier for welding operators to create quality welds regardless of joint placement. The wires produce low spatter levels to minimize post-weld cleaning, and have a fast-freezing, easy-to-remove slag to reduce the risk of slag inclusions.
FabCO Element 71C and 71M wires from Hobart are ideal for welding in shipbuilding, structural steel, heavy equipment manufacturing and general fabrication. 

Remote Control Technology Simplifies Ease of Use for Welders

Miller has expanded its ArcReach remote control technology to three additional machines: the XMT 350 CC/CV, XMT 450 CC/CV and Dimension 650 multiprocess welding power sources.  ArcReach allows welding operators to adjust and set voltage at the point of use — the weld joint — without the use of control cords, reducing downtime and improving safety by reducing exposure to tripping hazards and lessening operator fatigue associated with walking to and from the power source. The technology also eliminates the need to settle for less-than-optimal welding parameters, which helps improve weld quality, and it increases productivity by providing for more time to weld.
By providing complete control of voltage at the weld joint – without the use of control cords — ArcReach technology from Miller Electric helps welders improve their productivity, quality and safety.  

Compact Laser Cells for Welding Small Round Parts

Available with CO2 or solid-state lasers, this cell from Arnold is suitable for mass production or smaller batches, owing to the onboard loading and powerful CNC programming capabilities of the machine.
