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.

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.

Welding is often one of the most misunderstood manufacturing disciplines. Technology is amazing, and one need not look far to see the value that the ever-changing face of technology adds to the daily existence. Post-weld verification tools are used to collect not only information about welded assemblies, but also information about the welding operation in general. In today's media-saturated environment, mistakes can become global knowledge in a matter of minutes. These mistakes can also have a significant financial impact on the company. With the increasing presence of social media and the growing ability to hold a company publicly accountable for actions that may be perceived as negligent, it is becoming more crucial that companies take the proper steps to move with changing times to prevent errors in the manufacturing environment. The world has changed over the past couple of decades, and technology is certainly changing from year to year.

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.

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.

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.

Industry needs to transform how it educates its workforce in order to meet long-term goals and to maintain a competitive edge. Employers are demanding a different education level and set of skills for welding jobs that require programming, operation, and troubleshooting of robotic welding cells and other automated systems. Numerous states have enacted workforce programs and initiatives aimed to bolster the number of skilled workers in each state, sometimes with the help of the federal government, other times with help of other funding sources. The Trade Adjustment Assistance Community College (TAACCT) Grant Program received $2 billion of funding over four years. Mississippi also has 15 community and junior colleges that administers its Workforce Enhancement Training Fund, which allows these schools to partner with companies in the state to develop a loyal and productive workforce by creating custom job training programs carried out through the participating colleges. Welding theory and metallurgy, along with geometry and other topics, can prepare the welder of the future for advancements in welding process, equipment, and technology.

Guidelines on how to select the proper filler metals for some common types of steel are presented. Versatile steel can be alloyed and treated to produce various types of steels, which can be joined by numerous steel-based filler metals during the welding process. All steels can be rated on their weldability, which refers to how easy or difficult it is to produce a good-quality,crack-free weld on that particular type of steel. Low-carbon steels, with few additional alloying elements, have good weldability. Welds in steels with good weldability are less sensitive to cracking. Lower-strength filler metals usually offer easier weldability and typically cost low

Lisa Byall states that the low-hydrogen covered electrode is a better choice for working with weld deposit, due to its versatility, ease of use, and capability to reduce harmful hydrogen diffusion in the given deposit. She states that shielded metal arc welding (SMAW) in combination with low-hydrogen covered electrodes can prove to be the best choice when removing weld deposit. Low-hydrogen covered electrodes are the best choice for a variety of welding applications. Lisa Byall also informs that certain low-hydrogen covered electrodes are manufactured with special moisture-resistant coatings for better performance.

The ASME Section IX welding and brazing standard is widely used by public agencies and private companies concerned about the safety and integrity of welds. Just as specifications change when new materials are developed, ASME Section IX has changed to recognize modern welding waveforms. The changes involve the measurement of energy or power made at very rapid intervals, and the use of these to calculate heat input. These code changes establish the relationship between heat input across a range of power sources and welding waveforms. Welders, inspectors, and engineers should be aware of the new ways to calculate heat input. While no code can guarantee good workmanship, these changes make it easier for welders to use waveforms that help improve their welds. The new method will allow flexibility in the way one compares the heat input used in procedure qualification and in production welding.
