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).

Before You Automate That Welding Operation

No shop can benefit from welding automation if the operation simply consists of moving a bottleneck from one department into another. To avoid missing out on the overall productivity and efficiency a robotic weld cell can deliver, these four challenges must be addressed before automating the welding operation.

Top Ten Things to Consider with Through-Arm Robotic MIG Guns

Through-arm robotic MIG guns don’t require a mounting arm like conventional robotic MIG guns do. They provide a smaller work envelope that is ideal for working in tight spaces. Here are the top factors in selecting, installing and maintaining a through-arm robotic MIG gun. 
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

Increasing Aluminum Weld Strength and Quality

Aluminum is popular in many fabrication applications, but welding the material presents challenges of cracking, porosity and burn-through on thinner sections. Here are some critical insights on how to combat these potential problems. 
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. 
Inverter Welders

Field of Dreams

Take a look at how this Wisconsin fabricator uses the portable all-in-one Multimatic 200 multiprocess power source from Miller Electric to gain versatility and increase their welding productivity by 25 to 30 percent on field repair and fabrication jobs.
Laser Welders

Three Common Questions Concerning Laser Welding in Sheet Metal Fabrication

Many sheet metal fabrication shops still hesitate to invest in laser welding. They are missing out on the numerous competitive advantages and opportunities that it offers over conventional welding processes. Here are some insights that they need to know.
Electron Beam Welders

Electron Beam Welding vs. Laser Welding

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

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.
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.
Power Sources

Power Management Technology Eliminates Problems Caused by Dirty Power

Dirty power can impact weld quality in many ways. Here is one way to help avoid the problems caused by dirty power and improve productivity, efficiency and weld quality.
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.

Heat Resistant Covers Protect Weld Purging System in Hot Temperatures

Argweld Heat Resistant Covers from HFT are fixed onto the Tube and Pipe Weld Purging System with ties, and holes are provided for the PurgElite and PurgExtra fittings, such as inlet, exhaust and crimped end.
Tube and Pipe Weld Purging Systems from HFT pay for themselves in the first weld, saving vast amounts of purging time and inert gas costs.

Free Filler Metal App for Android Devices

To determine filler metal volume, users simply select the type of weld joint, enter its dimensions, and provide total weld length, material and transfer modes. The app recommends the type and amount of filler metal needed. It also calculates the heat input for a given application based on voltage, amperage and travel speed variables.
The Hobart Filler Metal Selector and Calculator determines the filler metal volume required and more for specific weld joints.

Welder/Generator for Critical Repair and Maintenance Applications

The 600 amp Big Blue 600 Air Pak features a powerful EPA Tier 4 Final–compliant Deutz engine rated at 65.7 hp and an Ingersoll Rand screw-type air compressor that is ideal for gouging. It can operate a full range of pneumatic tools, supplying up to 60 cfm of air at 100 psi with a 100 percent duty cycle. It also features improved arc characteristics, digital weld meters and display, and three-phase power available anytime — even while welding.
The 4 in electronic engine display allows users to precisely monitor fuel level, engine hours, coolant temperature, oil pressure, battery voltage, air pressure, and engine rpm — all in one convenient location. The display also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
The single-operator Big Blue 600 Air Pak from Miller Electric is ideal for welding, carbon arc gouging, auxiliary power, or running an air compressor in rail, mining, construction and fabrication work.
