Final answer:
Weld fittings designed for pipe trades often come with beveled edges, which allow for a secure and smooth weld. The beveled edge creates a suitable angle for welding, facilitating penetration and fusion of the welded joint. Option C is correct.
Step-by-step explanation:
Ready to use weld fittings with beveled edges are available for use in the pipe trades. When pipe fittings are beveled, they have an angled edge that is typically prepared at a 37.5 degree angle to allow for better penetration and fusion of the weld. This angle facilitates the joining process and ensures a stronger weld.
To elaborate, the bevel on the edge of the pipe fitting allows the welder to create a 'V' or 'U' shaped joint between the two pieces of metal, which can then be filled with welding material. The beveled edge provides a guide for the welder to create a smooth and secure connection that can hold up under pressure and is less likely to leak.
