Normally, the entire weld is not ground out, rather only enough to expose “wagon tracks”. These are lines of slag that are on either side of the built up convex region.See all results for this questionsp.info How does oxyacetylene welding get its name?WELDING REPORT GAS WELDING DEFINITION Oxyacetylene welding or gas welding gets its name from the two gases oxygen and acetylene that are used to produces a flame.

In addition, it has prime importance to welding since the earliest use of welding was for repair work. The most famous incident happened at the outbreak of World War I when German ships were interned in New York harbor. Their crews, hoping to make the ships inoperable, sabotaged the engines and machinery. However, by means of welding, repairs were quickly made and the ships were placed in transatlantic service to deliver material from the U.S. to Europe.
