Gas welding
Gas welding – interactive engineering module focused on gas welding. Learning format: Simulator · Interactive visualisation. Explains the principle, technical relationships and practical use.
Topic overview
The flame melts the component edges and filler rod. The heat source is less concentrated than an electric arc, producing a wider HAZ and greater distortion risk.
Variable oxygen/fuel-gas ratio. The diagram shows the inner cone, reducing zone, oxidising outer envelope, approximate maximum temperature and risks to the weld.
For repairs, erection, smaller thicknesses, local heating, simple piping and where equipment mobility matters.
A flame has a lower energy concentration than an arc. Incorrect manipulation readily increases HAZ width, distortion and surface oxidation.
