In many cases welding involves temperatures that are incredibly high.

Steel, for example, melts at around 2,800 degrees Fahrenheit. Welding is a very essential part of just about every modern industry. In the year 2000, a total of over 34.1 billion dollars was spent on welding related costs in American industry alone. If you break this down, it amounts to around $325 per American household.
In 2004, 429,000 professional welders were engaged in welding related work in the United States. They were engaged in a wide variety of different work, but a large percentage of them were working in fields that were extremely vital to the economy and security of the country.
