Chapter 1 The Problem and its Scope Introduction Welding is a fabrication or sculptural process that joins materials, usually metals or Thermoplastics, by using high heat to melt the parts together and allowing them to cool causing Fusion. Welding also can affect to our environment it involves the potential hazards for inhalation exposures that may lead to acute or chronic respiratory disease. Welding also can cause pollution, as an important operation in most industries. In all types of welding process, fume and gasses are formed as air pollutions. According to the grade 11 students in medina colleges Ipil Inc, say that, the reason why they took up (SMAW), it’s because welding is a career choice that does not a college degree and they also say that, they can get a welding certificate in as little as nine months to start earning a good living, and also, they said that they took SMAW because of the salary, which is a pretty typical middle class, and there are also many nations need for welders. According to previous research the growing demand for welders has caused many job seekers to consider a career in welding for a few reasons. The welding industry offers higher than average starting pay, good benefits and a bright future. Welding processes involve the potential hazards for inhalation exposures that may lead to acute or chronic respiratory diseases. Risk include asphyxiation due to dangerous inhalants, damage to skin and eye due to ultraviolet light, chemical or electrical fires and long – term negative effects from fumes.

Background of the Study Welding is the most important non-demountable assembly method. The industrial use of welding is very expensive due to the manual labour, which amounts to about 80 .... 90% of the production lost (Singh et al., 2011 and Ahuja, 2017). In industrialized countries, 0, 2...2% of the labour force works in the welding field. Most of the welders work on shipyards, they build transportation means, work in civil engineering, in the petrochemical industry, in the mining industry and metallurgy (Shah et al., 2011). These workers are exposed to smoke and toxic gas emitted following the welding processes, which may endanger their health. Furthermore, air pollution due to welding leads to certain consequents on human and environment (Rawat et al., 2014 and Akarsh et al., 2013).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
