When was the current world record set for deepest dry weld performed underwater?

In 1990, the deepest dry weld was performed at a depth of 1,075 feet below sea level. It may seem incomprehensible to believe that a normal dry weld can be performed underwater. Any welding method can be employed underwater in sealed chambers to stay dry while the weld is being performed.
