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).

How To Weld 3D Printed Parts

The 3D metal printing process is prone to capture microscopic inclusions and voids in the material. When these parts are welded, these micro voids coagulate into large bubbles of porosity that weaken the weld due to stress concentration in the area of the porosity. John DeLalio of EB Industries explains how electron beam welding can be used to address this issue.

Considerations for Consumables in Robotic Welding Applications

Did you realize a contact tip often serves as a barometer of the overall effectiveness of the welding process by indicating how optimized it is – or isn’t? To prevent time consuming and costly issues with joint access, here are some important reasons why consumables must be part of the planning process when working with an integrator to design a robotic welding system.

Welding Abrasion-Resistant Plate: Three Common Challenges and Their Solutions

Here are some tips that make it easier to avoid cracks and prevent lost time and money when welding these incredibly hard plates.
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

Using Shielding Gas Efficiently

Gas handling equipment is one area shops sometimes overlook to keep costs down to stay competitive. Proper gas-saver flowmeter regulators can ensure saving on the amount of shielding gas that is used with each pull of the trigger of the welding gun.

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. 
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.

Tube & Pipe Fabrication: Welding

With the new Tube and Pipe Weld Monitoring System from Xiris, tube and pipe fabricators can remotely view their live TIG, plasma or laser welding processes to clearly see if defects such as dross or porosity develop as the weld pool solidifies and monitor the condition of the weld tip, shielding gas and material fit up.
Here are some of the advances in tube and pipe welding equipment and accessories that are now available to help shops make money while meeting demands for more complex geometries, tougher materials, faster speed and higher quality.

Low Hydrogen Weld Deposit, Minimal Cracking Risks When Welding Pipe

Ideal for welding API 5L Grade X100 pipe or as an overmatch on API 5L Grade X80 pipe, FabCO 750M gas-shielded flux-cored wire from Hobart provides low diffusible hydrogen weld deposits (3.5 ml per 100 g of weldment) on high-strength applications and minimizes the risk of underbead cracking.
FabCO 750M gas-shielded flux-cored wire from Hobart provides low diffusible hydrogen weld deposits on high-strength applications and minimizes the risk of underbead cracking.

Submerged Arc Welding for Pipe Fabrication

In many shops, the submerged arc welding application involves restricted space or confined parameters that make equipment flexibility a necessity. With built-in fork pockets and caster wheels, the SubArc Portable Welding System can move the entire system to the workpiece. Easy positioning of the weld head to the point of the weld on the workpiece is possible through use of an integrated motorized column, manual telescoping boom, cross slides and 360 deg column rotation that contributes to the system’s ability to reach where the weld is needed.
The self-contained SubArc Portable Welding System from Miller Electric is a ready-to-weld system that contains the power source, column and boom on a mobile platform.
