2. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/wiki/Welding_Procedure...

   The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...

3. List of welding codes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_codes

   Covered electrodes for manual metal arc welding of non-alloy and fine grain steels. Classification ISO 3580: Covered electrodes for manual arc welding of creep-resisting steels - Code of symbols for identification ISO 3581: Covered electrodes for manual arc welding of stainless and other similar high alloy steels - Code of symbols for ...

4. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The cost of materials includes the cost of the base and filler material, and the cost of shielding gases. Finally, energy cost depends on arc time and welding power demand. [72] For manual welding methods, labor costs generally make up the vast majority of the total cost. As a result, many cost-saving measures are focused on minimizing ...

5. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   The oxy-acetylene (and other oxy-fuel gas mixtures) welding torch remains a mainstay heat source for manual brazing, as well as metal forming, preparation, and localized heat treating. In addition, oxy-fuel cutting is still widely used, both in heavy industry and light industrial and repair operations.

6. Lead burning - Wikipedia

   en.wikipedia.org/wiki/Lead_burning

   Oxy-hydrogen is considered to be the best, but is not easily portable. Oxy-natural gas is cheapest and is often used on fixed workbenches. As it is less hot, it cannot be used for some awkward positional (overhead) welding. Oxy-acetylene is the most common, as much leadwork is carried out on site and this is easily portable. A neutral flame is ...

7. Orbital welding - Wikipedia

   en.wikipedia.org/wiki/Orbital_welding

   It is very difficult to achieve the highest standards of quality and safety using manual welding. [4] This is due to certain welding positions, overhead and down-hand welds for example, often leading to faulty welds due to restricted access the user has in these welding positions.

8. 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).

9. Electroslag welding - Wikipedia

   en.wikipedia.org/wiki/Electroslag_welding

   Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in a different location. An electric arc is initially struck by wire that is fed ...
