Which process will create a stronger joint when working with metals?

Brazing a material creates a stronger joint because it involves the use of a filler metal that has a lower melting point than that of the workpieces. During brazing, the filler metal is heated to its melting point and flows into the joint by capillary action. The strength of the joint comes from the metallurgical bond formed between the filler metal and the base metals, which can often be equal to or greater than the strength of the base metals themselves.

Welding typically produces strong joints as well, as it involves melting the base metals together, but the effectiveness can depend on the technique and the base materials being joined. Soldering, on the other hand, is generally used for joining electrical components and does not provide the same strength as brazing or welding because it uses a filler metal with a much lower melting point. Crumpling is not a process that creates a joint but rather a form of deformation that does not serve any purpose in joining materials. Thus, brazing is recognized for producing reliable and durable joints in metalworking applications.
