PLAN No. 1142. SHIPBUILDING
Extensive use is made of the process in cutting all kinds and shapes of steel plate. Hydrogen is very generally used, instead of acetylene, and welding machines have been introduced. Welding proper is more generally applied in reclamation work, damaged or broken parts of the ship and of its machinery and propellers being often welded by this process.
Electric arc welding is fast coming to the front in this field, except for cutting where the gas process can not be replaced.
