The reactive nature of aluminum to the welding arc, which is much more pronounced than that of other base materials, presents many challenges, including excess heat input and burn-through, porosity, poor bead appearance, poor fusion, and cracking. Technology advancements have made tackling these challenges easier by providing a balance of high travel speeds with a narrow, focused arc

Massachusetts-based Woods Hole Oceanographic Institution (WHOI) is dedicated to researching the impact that oceans have on the Earth as a whole, and sometimes that means diving to treacherous depths to gather pertinent information. For an excursion at Challenger Deep, a portion of the South Pacific Ocean off the coast of the Marianas Islands, WHOI fabricated a hybrid remotely operated vehicle able to withstand the 15,751 PSI of pressure, allowing scientists to gather valuable data from more than 35,000 feet below sea level.
