- Bonding (mechanical) : A variety of methods, including the use of fasteners, adhesives, fillers such as soldering, and actual merging as in welding, for joining objects; bonding may be adequate if mechanically solid, or may require additional care to be electrically conductive or liquid-tight
- Arc welding : Add brief definition or description
- Flux-cored arc welding : Semi-automatic or automatic arc welding process, requiring a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply.
- Oxyacetylene welding : Add brief definition or description
- Oxyhydrogen welding : Add brief definition or description
- Spot welding : Add brief definition or description
- Thermite : A class of mixtures of a powdered metal and a powdered metal oxide, which, when ignited, generates extreme heat for military and civilian applications
- Acetylene : Add brief definition or description
- Argon : A chemical element with atomic number 18. It is an inert gas in group 18 of the modern periodic table.
- Hydrogen : The most abundant and lightest chemical element which has atomic number Z = 1 and chemical symbol H.
- Gas compressor : A machine that increases the pressure of a gas by reducing its volume.
- Induction heating : A process by which materials that are susceptible to electrical fields are heated by an alternating or varying magnetic field from the use of alternating current (AC).
- Magnesium : The metallic element that has atomic number 12 and belongs to alkaline earth metal group.
- Materials science : A multi-disciplinary field involving the properties of matter and its applications to various areas of science and engineering.
- Soldering : A bonding or fastening technique for joining pieces of metal with a filler metal, which has a lower melting point, below 800 degrees Fahrenheit or 427 degrees Celsius, than the pieces to be joined and is melted by heat conducted through the work
