TIG welding (TIG welding) is a kind of welding method with pure Ar as shielding gas and tungsten as the electrode. MIG welding, i.e. GMAW, is a welding method of GMAW with AR and other inert gases as the main shielding gas, including pure AR or AR gas mixed with a small amount of active gas (such as O2 below 2% or CO2 below 5%). MIG welding wire is wound in layers or discs.

Molding methods for plastic and metal parts

If a part can be made from a piece of metal sheet by cutting and bending, then sheet metal processing can be applied. Most common methods are: first laser cut the sheet and then bend or punch it.

CNC machining is a digital manufacturing process where a block of solid raw material is cut into a certain shape or structure through the cutting tools of a computerized machine. The computer program will make the servo motors to move in different directions and locate the cutting tools at the accurate position.

Literally, rapid prototyping means do a prototype quickly. In practice, it gets a bit more complicated than its literal meaning.
