  • The 3 Most Dangerous Mistakes Beginner Welders Make

    Dec 15, 2012 · This layer of mill scale occurs as the steel is heated and cooled at the steel mill and it’s a very important part of the welding procedure that you remove this mill scale. If you fail to clean the work piece before welding it will be more difficult to get good weld penetration because the rust, paint, dirt, etc. will take away heat from the actual surface of the metal and the weld.Read More

  • The invisible risks of welding The FABRICATOR

    Jul 10, 2007 · However, welding is loud enough to cause minor nerve cell damage, and minor damage on a daily basis adds up over the years. Even moderately loud noise, such as that produced by welding, leaves auditory nerve cells affected permanently. Damaged cells do not mend, and new ones don't grow. The long term result is loss of hearing.Read More

  • Understanding Weld Cracking, Its Causes,

    Welding at high voltages, especially with an electrode or welding wire that creates a particularly fluid weld pool can also cause the resulting weld bead to be more concave. This again reduces the throat thickness and weld strength, making it more prone to bead shape cracking.Read More
