[vc_row full_width=””][vc_column width=”1\/1″][vc_column_text]Welding joins materials by causing\u00a0coalescence.\u00a0Many different\u00a0energy sources\u00a0can be used for welding, including a gas\u00a0flame, an\u00a0electric arc, a\u00a0laser, an\u00a0electron beam,\u00a0friction, and\u00a0ultrasound.<\/p>\n
A cutting torch head is similar to a welding torch but can be identified by the oxygen blow out lever or trigger. Once the metal is heated to a bright red,\u00a0oxygen is supplied to the heated parts by pressing the trigger. This forms an oxide with a\u00a0melting point that is around half that of the metal. Plasma cutting is an additional method.<\/p>\n
