3. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   For the play, see Welded (play). Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt ...

   Example of Rotary friction welding weldability table. [31] This is the basic table because the currently known list of materials is much larger and the name alloy systems are classified by a number system or by names indicating their main alloying constituents (DIN and ISO). Sometimes an interlayer is used to connect non-compatible materials.

6. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   Gas tungsten arc welding. Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert ...

7. Submerged arc welding - Wikipedia

   en.wikipedia.org/wiki/Submerged_arc_welding

   Submerged arc welding. The welding head moves from right to left. The flux powder is supplied by the hopper on the left hand side, then follow three filler wire guns and finally a vacuum cleaner. Pieces of slag from submerged arc welding exhibiting glassy surface due to silica (SiO 2). Submerged arc welding (SAW) is a common arc welding process.
