Welding Mild Steel Hazards. Acute effects are eye nose and throat irritation and shortness of breath. Also they should avoid.
Welding arcs and sparks can ignite combustible and flammable materials. One of the main reasons MIG is a popular choice for welding mild steel is that the technique is quite simple allowing the user to focus on the materials they are welding. As a result of The International Agency for Research on Cancer IARC releasing scientific evidence that exposure to mild steel welding fume can cause lung cancer and possibly kidney cancer in humans mild steel welding fume was reclassified as a human carcinogen by the Workplace Health Expert Committee in 2019.
What about mild steel.
Mild steel contains traces of manganese welding rods and wire also contain small quantities of magnesium. Steel alloys iron stainless steel nickel alloys. Working with stainless steel may produce welding fumes containing nickel and chromium. MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool joining the two base materials together.
