2. Hot plate welding - Wikipedia

   en.wikipedia.org/wiki/Hot_plate_welding

   A heated tool is placed against or near the two surfaces to be joined in order to melt them. Then, the heat source is removed, and the surfaces are brought together under pressure. Hot plate welding has relatively long cycle times, ranging from 10 seconds to minutes, compared to vibration or ultrasonic welding. However, its simplicity and ...

3. 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 ...

4. List of welding processes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_processes

   This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

5. Pillow-plate heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Pillow-plate_heat_exchanger

   Pillow-plate heat exchangers are a class of fully welded heat exchanger design, which exhibit a wavy, “pillow-shaped” surface formed by an inflation process. Compared to more conventional equipment, such as shell and tube and plate and frame heat exchangers, pillow plates are a quite young technology. Due to their geometric flexibility ...

6. Friction stir welding - Wikipedia

   en.wikipedia.org/wiki/Friction_stir_welding

   Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.

7. Blacksmith - Wikipedia

   en.wikipedia.org/wiki/Blacksmith

   A modern blacksmith has a range of options and tools to accomplish this. The basic types of welding commonly employed in a modern workshop include traditional forge welding as well as modern methods, including oxyacetylene and arc welding. In forge welding, the pieces to join are heated to what is generally referred to as welding heat. For mild ...
