Gluing wood with friction Friction welding is the process of welding two objects by using the heat produced through mechanical friction. Has a number of industrial uses for welding metals and plastics, but now thanks to a process called linear friction, can be applied to wood.
Friction welding Metal welding method with friction. Here are stacked one wheel for crawler excavator.
Tungsten arc welding This is a TIG welding (ή GTAW), using a tungsten electrode and argon gas. The electrode together with the weld metal form an electrical circuit, and an electric arc is created at the point of welding. In this welding method the arc melts the welded metal, and not the electrode. Argon gas comes out of the welding gun, and is used to protect molten metal from oxidation.
Laser welding of metals The process of welding two metals with a laser. Laser welding is categorized as thermal conductivity welding or deep welding. In thermal conductivity welding, the laser beam melts the surface of the metal. The molten metals flow together and the solidified melt permanently binds the material. In terms of quality, speed and economy, Laser welding systems are superior to conventional processes for industrial use.
Explosions for mining A collection of videos with explosions during mining operations.
Using a friction drill Friction drills used to build powerful connections, as it does not remove metal from the hole, but the melt and create a strong wall around the hole. So, a screw can be caught with more bends in the metal and the link to become much stronger. The friction drill bits manufactured from tungsten carbide, a material 3 times stronger than steel. Here our Piet Hein shows how friction works a drill.
Friction drilling Friction drills used to build powerful connections, as it does not remove metal from the hole, but the fuse in order to create a strong wall around the hole. This way of connection joints are reinforced and made more durable.
