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
Agamassan Agamassan Agamassan is a porous substrate used to safely absorb acetylene and thus allow the transport, storage and commercial exploitation of the otherwise unstable gas. It was developed and patented by the Swedish Nobel Laureate and industrialist Gustaf Dalén. Dalén was prominent in developing applications for acetylene. Acetylene can readily explode when in liquid or solid form or while being pressurized, if it is pure. Dalén himself was blinded in an acetylene explosion. In 1896, French chemists Georges Claude and Albert Hess discovered that large quantities of acetylene could be dissolved in acetone and rendered nonexplosive. As the liquid was
