Spending an entire day at the welding table is stressful. The UV radiation and the welding fumes are just some of the factors that can be dangerous if you do not have the right protection. The correct welding equipment makes the crucial difference in this area. ...
Mixturesdo not have fixed precise melting and boiling points (whichelementsandcompoundsdo have), but instead mixtures melt / freeze and boil / condense over a range of temperatures according to the physical properties of the different constituents of the mixture. ...
7b) Selective Laser Melting (SLM):Unlike SLS, this technique isdesignedto completely melt and fuse metallic powders together. It can create fully dense materials (layer by layer) that have mechanical characteristics similar to those of traditional manufactured metals. This is one of the fast-develo...
