What is Welding?

  • Welding joins two pieces of metal by the use of heat, pressure, or both
  • Brazing or soldering involves a filler metal which has a lower melting point than the metal pieces to be joined
  • Metal cutting is done by heating the metal with a flame and directing a stream of pure oxygen along the line to be cut

Type of Welding

  • Arc Welding
  • Shielded Metal Arc Welding (SMAW)
  • Metal Inert Gas (MIG)
  • Tungsten Inert Gas (TIG)
  • Plaza Arc Welding (PAW)
  • Submerged Arc Welding (SAW)
  • And Many More…..more than 80 in all

Health Hazards

  • Gases and Fumes…
  • Welding “Smoke” is a mixture of very fine particles called fumes and gases
  • Welding “Smoke” contains fumes and gases including…
  • Chromium, nickel, arsenic, asbestos, manganese, silica, beryllium, cadmium, nitrogen oxides, phosgene, acrolein, flourine compounds, carbon monoxide, cobalt, copper, lead, ozone, selenium, and zinc

Short-term exposures

  • Ultraviolet rays given off by welding can react with hydrocarbon solvents such as…
  • Trichloroethylene; 1,1,1-trichloroethane; methylene chloride; & perchloroethylene to form phosgene gas
  • Even a very small amount of phosgene gas may be deadly
  • Arc welding should never be performed within 200 feet of degreasing equipment or solvents

Long-term exposures

  • Studies of welders, flame cutters, and burners have shown that welders have an increased risk of lung cancer…
  • and…possibly cancer of the larnyx and urinary tract
  • Remember… welding “smoke” can include cancer causing agents such as…cadmium, nickel, beryllium, chromium, and arsenic
  • Welders may experience a variety of chronic respiratory problems, including…
  • Bronchitis, asthma, pneumonia, emphysema, pneumoconiosis, decreased lung capacity, silicosis, and siderosis
