Abstract:
Safety in welding is a very important aspect. Welding is one of the most widely used metal
fabrication methods in world wide. Welding is safe operation when carried out under normal and correct
workshop conditions, but it must be pointed out that equipment free from defects and well arranged, properly ventilated , tidy workplace are important factors for safe working. Even though, welding is
carried out widely across the world, when certain basic measures and precautions are not followed, it
results in injuries, discomfort, loss of eye sight after a longer period, or sometimes even leading to death
of the people work there. There are a large variety of welding and allied processes used in the modern industry. In general
welding processes can be divided into the two basic categories, as fusion welding and solid-state welding. These processes differ in the manner with which heat, pressure or both are applied and the equipments
used for the process. Shielded Metal Arc Welding (SMAW), Submerged Arc Welding (SAW), and Gas
Metal Arc Welding (GMAW) account for 60-70% of welding activities in most of the industries. Its’ ease
of operation, flexibility, and efficiency make welding a viable and attractive process in modern industries. Welding is one of the major processes in High Pressure Boiler Manufacturing Industries also. Here, modern welding machines are used to produce more productive and high quality Boiler components. Various processes of welding are adopted at High Pressure Boiler manufacture. In High Pressure Boiler
Production, Tubular Production is the very important process, since it involves welding of tubular
products where and iv steam at very high pressure and temperature of about 570 atmosphere and 600°C
shall be circulating inside. The existing welding process of the Tubular Production and the environment in
which the welders work in these machines are studied to bring out improvement in their working
conditions.
