PEEK is laser weldable. (Keeping up with Auxiliaries).Leister Technologies LLC in Schaumburg, Ill., has adapted its Novolas diode laser See laser diode.-welding equipment to weld PEEK PEEK - The command in most microcomputer BASICs for reading memory contents (a byte) at an absolute address. POKE is the corresponding command to write a value to an absolute address. This is often extended to mean the corresponding constructs in any High Level Language. Much hacking on small microcomputers without MMUs consists of "peek"ing around memory, more or less at random, to find the location where the system keeps interesting stuff. resins supplied by Victrex USA Inc. Previously, it was not feasible to laser weld PEEK due to the resin's semi-crystalline nature and high melting point melting point, temperature at which a substance changes its state from solid to liquid. Under standard atmospheric pressure different pure crystalline solids will each melt at a different specific temperature; thus melting point is a characteristic of a substance and can be used to identify it. When heat is applied continuously and in sufficient quantity to such solids, the temperature rises steadily until it reaches the point at which liquefaction occurs., both of which retard the ability of PEEK to absorb laser energy.
