Even though __ is slower and requires a higher skill level as compared to other manual welding processes, it is still in demand because it can be used to make extremely high-quality welds in applications where weld integrity is critical. a. OAW b. SMAW c. GTAW d. GMAW

The correct answer is c. GTAW (Gas Tungsten Arc Welding).<br /><br />Gas Tungsten Arc Welding (GTAW), also known as TIG (Tungsten Inert Gas) welding, is a welding process that uses a tungsten electrode to produce the weld. It is slower and requires a higher skill level compared to other manual welding processes, but it is still in demand because it can be used to make extremely high-quality welds in applications where weld integrity is critical.<br /><br />GTAW is particularly useful for welding materials that are difficult to weld using other methods, such as stainless steel, aluminum, and magnesium. It is also commonly used in aerospace, defense, and medical industries, where the quality of the weld is of utmost importance.<br /><br />The other options, OAW (Oxygen Arc Welding), SMAW (Shielded Metal Arc Welding), and GMAW (Gas Metal Arc Welding), are also welding processes, but they do not have the same level of precision and quality as GTAW.
