Various safety measures in Welding Process
Various safety measures in GMAW
1. The types and amount of fumes and gas present during welding depend on electrode being used, the alloy being welded, and the presence of any coatings on the base metal. To guard against potential hazards, a welders should keep his head out of the fume plume and avoid breathing the fumes and gases caused by arc. Ventilation is always required

2.Electrode shock can result from exposure to the high open-cuircuit voltages associated with welding power supplies. All electrical equipment and the workpiece must be connected to an approved electrical ground. Cables should be off sufficient size to carry the maximum current required

3.Insulation should be protected from cuts and abrasion, and the cable should not come into contact with oils, paints, or other fluids which may cause deterioration. Workareas, equipment and clothing must be kept dry at all times. The welders should be well insulated, wearing dry gloves, rubber soled shoes, and standing on a dry board or platform while welding
4. Radiant energy , especially in the utraviolet range, is intense during GMAW. To protect the eyes from injury, the proper filler shade for the welding current level selected should be used. These greater intensities of utraviolet radiation can cause rapid disintegration of cotton clothing

5.Leather,wool, and aluminum-coated cloth will be better withstand exposure to arc radiation and better protect exposed skin surfaces

6. When noise has been determined to be excessive in the work area,ear protection should be used. This can also be used to prevent spatter from entering the ear
