What is checksum and how to calculate and use checksum values to verify data and file integrity Checksum is a calculated value that is used to determine the integrity of data. Checksum serves as a unique identifier for the data (a file, a text string, or a hexadecimal string). If the data changes then so does the checksum value.
First off, let's define the TIG welding process and provide some history. TIG stands for Tungsten Inert Gas and is technically called Gas Tungsten Arc Welding or GTAW. The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. The tungsten and weld puddle are protected and cooled with an inert gas, typically argon. TIG welding is similar to oxy-acetylene welding in that you use a filler material for build-up or reinforcement.
