2. Gas metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_metal_arc_welding

   Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).

3. List of scale model sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_scale_model_sizes

   This is a scale used for some aircraft carrier models. This scale is also used for some pre-finished die cast airliner models. 1:720: 0.423 mm: Ship models: This was a standard size for ship models produced by Revell and Italeri but they have moved from it. 1:700: 0.435 mm: Ship models: This is the scale that most manufacturer chose to produce ...

5. Moving heat source model for thin plates - Wikipedia

   en.wikipedia.org/wiki/Moving_heat_source_model...

   In the 1930s metallurgists Albert Portevin and D. Seferian attempted to experimentally determine heat transfer characteristics in welding. [1] They correlated the effects of several factors—material properties, welding process, and part dimensions—on temperature distribution, by performing oxyacetylene (gas) and covered electrode (arc) welds on plates and bars of various profiles, and ...

7. Heat-affected zone - Wikipedia

   en.wikipedia.org/wiki/Heat-affected_zone

   In fusion welding, the heat-affected zone (HAZ) is the area of base material, either a metal or a thermoplastic, which is not melted but has had its microstructure and properties altered by welding or heat intensive cutting operations. The heat from the welding process and subsequent re-cooling causes this change from the weld interface to the ...

8. Shielding gas - Wikipedia

   en.wikipedia.org/wiki/Shielding_gas

   C-25 (75% argon/25% CO 2) is commonly used by hobbyists and in small-scale production. Limited to short circuit and globular transfer welding. Common for short-circuit gas metal arc welding of low carbon steel. C-20 (80% argon/20% CO 2) is used for short-circuiting and spray transfer of carbon steel.

9. Symbols and conventions used in welding documentation

   The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
