Welding welding was invented in 1893, and around that time another process, oxyfuel welding, became well established. Acetylene was discovered in 1836 by Edmund Davy, but its use was not practical in welding until about 1900, when a suitable torch was developed. At first, oxyfuel welding was one of the more popular welding methods due to its portability and relatively low cost. As the 20th century progressed, however, it fell out of favor for industrial applications. It was largely replaced with arc welding, as advances in metal coverings (known as flux) were made. Flux covering the electrode primarily shields the base
USS Wave (1836) USS Wave (1836) USS "Wave" was a schooner in commission in the United States Navy from 1836 until probably 1846. "Wave" was a schooner-rigged yacht designed along pilot boat lines by John C. Stevens and built for him in 1832 at New York City by Brown and Bell. The U.S. Navy purchased her in 1836 for use in the Second Seminole War. In that campaign, she cruised the Florida coast in support of United States Army operations until 1840. After 1840, "Wave" served as a surveying vessel along the United States East Coast under the command of Lieutenant John R.
