Automation Alternatives recently introduced a fiber laser welding system called RubyLaser that is perfect for joining dissimilar materials. Its spot size is as small as 0.001 to 0.002 in. and fast weld speeds allow the system to deliver high power density. These characteristics make it perfect for welding together materials that are not identical.
Typical materials include stainless steel, titanium, aluminum, nitinol and more.
One of the flame cutting services we offer at Sullivan Precision Plate is High Definition Plasma. Over the next few weeks, we’re going to dive into the complex process of plasma cutting (with the help of our friends from How Stuff Works).
This week, we’re going to take a quick chemistry lesson. Most of us know the three states of matter: solid, liquid and gas. Many of us forget, however, the fourth state of matter: plasma. Plasma is what happens when you heat a gas to an extremely high temperature.
The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus surrounded by a cloud of electrons. In plasma, the electrons separate from the nucleus and begin to move around quickly, leaving behind their positively charged nuclei. These positively charged nuclei are known as ions. When the fast-moving electrons collide with other electrons and ions, they release vast amounts of energy. This energy is what gives plasma its unique status and unbelievable cutting power.
