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.

Industry Standards Are Evolving Faster Than Ever

Fuel economy mandates are dictating significant design changes to new vehicles and trailers. To comply with these changes, shops must learn new techniques while training technicians to weld aluminum in addition to steel. To reduce the already expensive overhead costs auto body and repair facilities endure, it is critical that the welding machine provides versatility and timesaving features.
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.

Ways to Get the Most Out of Your MIG Gun Consumables

Nozzles should be cleaned at least every other welding cycle in a robotic welding operation to prevent spatter buildup that can lead to poor gas shielding or cause short-circuiting between the contact tip and nozzle. Heavy-duty consumables are recommended for high-temperature robotic welding applications. If the robotic welding operation calls for a heavy-duty retaining head, pair it with heavy-duty contact tips. Always check the torques of the body tube and end fittings regularly to prevent loose fitting cables that can cause overheating and lead the robotic MIG gun to prematurely fail.
Here are a few of the best practices that every welding operator should know when it comes to choosing and maintaining nozzles, contact tips, retaining heads and gas diffusers, and cable.

New Arc Process for More Efficient Welding

A new algorithm uses the high processing power, large memory, extremely fast system bus and highly dynamic wire feed speed of the latest MIG/MAG power source platform to ensure an extremely stable arc with minimal spatter.

Field of Dreams

High Tech Welding has gained 25 to 30 percent in productivity in its field repairs since it began using the Multimatic 200 a year ago. The portability and multiprocess capabilities of the unit are at the heart of those benefits.
Take a look at how Wisconsin fabricator High Tech Welding uses a portable all-in-one multiprocess power source to gain versatility and increase their welding productivity by 25 to 30 percent on field repair and fabrication jobs.

What You Must Know About Robotic Welding

Lloyd Steed of Tregaskiss identifies the key factors that must be understood to manage a profitable and productive robotic welding operation that really gains a competitive edge and makes the most out of its investment.

Take Welding to the Next Level

The Continuum 350 features two new welding processes. Versa-Pulse is a fast, low-heat and low-spatter process that delivers faster travel speeds for semi-automatic and automated welding applications, also resulting in increased productivity. This process is ideal for welding on thin materials (up to 1/4 in), such as sheet metal and tube applications, and offers a greater wire feed speed range than short circuit or Regulated Metal Deposition processes. A High-Deposition MIG process offers higher deposition rates and lower heat input than standard spray transfer, resulting in faster welding, increased productivity and better quality. The process works well for welding thicker materials and on larger welds (6 mm to 8 mm).
The Continuum 350 from Miller Electric provides a competitive edge through exceptional arc performance, unique processes and programs, and standard weld data gathering.

More Practical and Energy-Efficient Stick Welding

The TransPocket 150 and 180 systems from Fronius use hand-held welding torches that can utilize electrodes with diameters up to 5/32 in and power sources that are also suitable for TIG welding up to 220 A.

Ergonomic Wand, Carbon Fiber Brushes for MIG and TIG Weld Cleaning

The Surfox Wand is articulated to allow a greater range of motion. 
It is compatible with the company’s carbon fiber brushes with segmented sleeves that are used for cleaning MIG welds. The segmented sleeves can be trimmed away with a pair of long nose pliers, up to three times,to get more life out of each brush. The triangular brush is used for cleaning larger surface areas, whereas the cylindrical sleeve brush is used for tight corners and spot welds. The new wand also remains compatible with tungsten inserts and high conductivity cleaning pads.
The Surfox Wand from Walter Surface Technologies features a quick-change system for accessories to clean larger and hard-to-reach areas at an optimal rate.
