What kind of materials can be welded using GMAW?

GMAW, or Gas Metal Arc Welding, is a versatile welding process capable of joining a wide variety of metals. The correct response highlights that GMAW can effectively weld various materials, including both carbon steel and stainless steel. This is due to its adaptability in handling different metal compositions and thicknesses, making it ideal for many industrial applications.

Carbon steel is commonly used in structural applications due to its strength and durability, while stainless steel is favored in environments requiring corrosion resistance. GMAW's ability to maintain a stable arc and control heat input allows for precise welding, which is crucial when working with these materials. Additionally, GMAW can also be used with other metals beyond carbon and stainless steel, such as aluminum and copper, further emphasizing its versatility in material compatibility.

The other options focus on limitations that do not accurately reflect the broad capabilities of the GMAW process. GMAW is not restricted to specific materials like only aluminum and brass, nor is it limited solely to carbon steel. It is capable of welding a range of thicknesses, so the claim regarding only thick metals is also misleading. Therefore, the ability of GMAW to weld various materials, including carbon and stainless steel, highlights its utility in diverse fabrication and repair
