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.
For mig welding mild steel, use e70s6 wire and 75/25 argon/c02, if you need to weld outside get some Hobart Fabshield 21b. Tig Welding Steel Tig welding is used extensively for pipe welding, aerospace, aviation, biomedical implants, fabrication of race cars, choppers, etc.
