Unlocking the Power of OSHA for Welding Safety
Just as a gamer needs the right skills to level up, a welder needs to understand OSHA guidelines for their safety and success.
Welding is a process that joins metals by applying heat and pressure. The earliest known examples of welding come from the Bronze Age during the Middle Ages. For thousands of years, welders have transformed base materials into new items or have used their craft to repair old or broken items. Individuals in the welding trade improve their skills with hands-on learning and dedication to the process of welding.
There are four main types of welding and a variety of uses. With attention to detail and passion for the trade, students can gain the skills and knowledge to enter this exciting industry. How much do you know about the different welding processes? Keep reading to learn how weld operators perform four types of welding.
MIG welding is a type of arc welding that uses a continuous wire called an electrode. The electrode passes through the welding gun, enters the weld pool and joins two objects together. The welding operator also uses shielding gas that travels through the welding gun and protects against contamination.
MIG welding is one of the most common type of welding. It can be used in the automotive industry for repairing vehicle exhausts, as well as in the construction industry to create homes and buildings. Some advantages of MIG welding include:
Like MIG welding, TIG welding also uses an electric arc. Welders use an electrode made of tungsten, one of the toughest metal materials found in nature. Tungsten does not dissolve or burn off. Welding can be done with the use of a filler metal or without a filler metal (this process is called fusion).
TIG welding also requires an external gas supply, such as argon or helium. Some advantages of TIG welding include:
Weld operators use shielded metal arc welding, also called stick welding, for repairs and production. The type of welding uses a consumable and protected electrode, or stick. The stick softens and combines metals by heating them with an arc between a covered metal electrode and the base metal work piece. As the stick melts, its protective cover also melts and shields the weld area from oxygen and other gases that may be in the air.
Stick welding is portable and can be used in many different kinds of environments. Shielded metal arc welding is used in:
Flux-cored arc welding is similar to MIG welding because both use equipment, continuous wire and power supplies. Like MIG welding, this type of arc welding can use a shielding gas. However, some weld operators choose not to use a shielding gas with flux-cored welding.
Weld operators unite a continuous electrode with a base metal. The electrode is a hollow tube filled with flux that is fed through the weld gun and into the weld pool. A flux shield offers protection against the wind when operators are welding outdoors. Some benefits can include:
