U.S. manufacturing needs to embrace automation, including welding robotics, for the right applications. Robots, welding or otherwise, will not take over manufacturing jobs, but instead will enhance future employment opportunities. The robotics industry actually strengthens the U.S. economy, and industrial robots will help U.S. companies compete in the wider, global marketplace. It's a myth that the robotics are generally costly and all the manufacturers are not able to bear the cost. But, the actual cost of robotic systems, which have become preengineered welding work cells, has decreased over the years. With common components and consistent manufacturing, the costs for robotic welding systems continue to decrease. With options for offline programming, human machine interfaces (HMIs), and intelligent robotic welding solutions, such as vision and laser tracking, a robotic system can be implemented without a rocket scientist on staff.

Chief Warrant Officer Stacey-Ann McNish-Rodriguez explains why she chose to become a welder in the U.S. Army. She was fascinated with the welding process because she loved to create things. In February 1994, she enlisted in the U.S. Army as an Allied Trades Specialist. Now, 20 years later, Chief Warrant Officer 3 McNish-Rodriguez directs the setup, operation, and maintenance of machine tools and welding equipment used to fabricate or repair parts, mechanisms, tools, and machinery. To keep up with the latest welding technology and procedures, McNish Rodriguez recently underwent 12 months of training at The Lincoln Electric Co. in Cleveland. During her time in Cleveland, McNish-Rodriguez participated in welding-design and welding-productivity seminars, training in advanced robotics and Six Sigma operational analysis. Source

Experts suggest that selecting the right welding gun results in reduced operating costs, higher-quality welds, and enhanced welder satisfaction. They suggest that selecting the proper gun for the welding application is critical to the fabricating process whether the job involves shipbuilding, construction, or heavy fabrication. Welders need to consider their personal preferences along with the gun's total cost of ownership, including replacement parts, and expected service lifespan. Selecting the right gun can also save the user significant time and money in the long run. A welder can determine the gun's necessary duty cycle, such as how long it can run continuously in a 10-mm cycle. The welder can determine the gun's necessary duty cycle after the proper amperage is determined. Experts also state that a 60% duty cycle is most commonly used and is sufficient when the gun is used in semiautomatic applications. Source

The process of combining lasers with gas metal arc welding (GMAW) in a single weld pool, known as hybrid laser arc welding (HLAW), has been in existence for almost 30 years. When examining whether HLAW will be of benefit, many engineers look at their present weld joints and simply substitute a 'laser weld' for the existing process. While the higher welding speed was a benefit compared with submerged arc welding (SAW), another advantage was the lower distortion compared to arc welding. In addition, postwelding processes such as leveling and dealing with general distortion could be reduced or eliminated. There are limited industry specifications that address HLAW In the case of the Meyer Werft application, the shipyard worked closely with Det Norske Veritas (DNV) to develop specifications for HLAW as it applied to ships. ASME has developed a specification for hybrid welding, and the American Welding Society is in the process of forming Subcommittee C7D to develop specifications for H LAW. Source

The right combination of consumable chemistry, process, and equipment produces high-quality, 53-ft long welds at Great Dane Trailers, a refrigerated-trailer manufacturing plant. Great Dane's fabrication crew uses Power Wave® welding machines from Lincoln Electric with pulse waveform technology for automated welding on the refrigerated trailers' aluminum floors, a complex process that involves a continuous, 53-ft-long weld of 12-in, boards across the entire trailer floor. The system features ten boom-mounted wire feeders and fixed welding guns on an automated setup with a mechanical gantry that rides up and down the floor on rails. Welders at Great Dane selected a consumable specifically designed for the trailer manufacturing industry, SuperGlaze® 5356™ GMA welding wire by Indalco Alloys. This aluminum alloy GMAW wire was designed to provide weld pool clarity and arc action, as well as wetting for both semiautomatic and high-productivity automatic applications. Source
