Welding Facts

  • In many situations, welding involves temperatures that are incredibly high. Steel melts around 2800 degrees Fahrenheit.
  • Welding and/or fabrication is a very essential part of almost every modern industry.
  • In 2000, over 34.1 billion dollars were spent on welding related costs in American industry alone. After breaking this down, it amounts to $325 dollars per American household.
  • In 2004, over 429,000 professional welders were engaged in welding related work in the US. They were involved in various welding projects, but a large percent were working in fields that were extremely vital to the economy and security of the country. The average age of these welders was 54 years old, many of these welders will be reaching retirement age in the next ten years that the US Department of Labor estimates a shortage of 250,000 welders by the year 2010.
  • There are various forms of welding used today. The most common types use an "arc" to heat the metals to fuse them are Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), and Shielded Metal Arc Welding (SMAW). Other types do not require an arc, but rather electrical resistance and pressure which is called Resistance Welding

Mig Welding Facts:

  • Uses a consumable wire electrode during the welding process that is fed from various spool sizes.
  • Provides a clean and uniform weld bead,
  • Provides a slag - free weld bead,
  • Maintained by shielding gas, usually - argon-argon - 1 to 5% Oxygen, argon - 3 to 25% co2 and argon/helium gas.
  • Considered to be a semi - automatic welding process,
  • Allows easy welding in all positions,
  • Can generate long welds without frequent starts or stops,
  • Needs less cleanup

Aluminum Facts:

  • A metallic element with symbol Al, aluminum is the 3rd most plentiful element in the Earth's crust, behind that of oxygen and silicon. The metal has strong affinity towards oxygen and hence is not found in the elemental form but in combined states, such as silicates or oxides.
  • Bauxite is the main mineral ore of aluminum, which is abundantly available in tropical areas, such as - Africa, the West Indies, South America and Australia. Bauxite contains all types of impurities - mostly metals, such as iron - but comprises of 45 % to 60 % aluminum oxide, or alumina.
  • In its metallic form, aluminum metal does not occur naturally. It occurs only in combination with other minerals in the form of oxide or silicate compounds that constitute about 8% of earth's crust.
  • According to professional estimates, about 29 million tons of aluminum is required to meet the global ongoing demand every year. Of this total 29 million tons of total aluminum, around 22 million tons is new aluminum and 7 million tons is obtained by recycling the aluminum scrap. About 25% of aluminum used across the world is recycled material.
  • Fact - 50% of the aluminum cans used today in the US is recycled aluminum.
  • According to estimates since 1972 around 16 million tons of aluminum cans have been recycled. These 785.6 billion aluminum cans if placed end-to-end could stretch to the moon more than 249 times, which is astounding!
