Question

“Joining process has been evolving based on need”. Analyze

Answer 1

Joining includes welding, brazing, soldering, adhesive bonding of materials. • They produce permanent joint between the parts to be assembled. • They cannot be separated easily by application of forces.

Joining is an important process in a number of industries, such as aerospace, automotive, oil, and gas. Many products cannot be fabricated as a single piece, so components are fabricated first and assembled later. ... Metal joining is a process that uses heat to melt or heat metal just below the melting temperature

The joining of materials is an important technology in many manufacturing industries. Most products, machines or structures are assembled and fastened from parts, and the joining of these parts may be achieved through rivets, seaming, clamping, soldering, brazing, welding and the use of adhesives.
