All of the above.

The process of joining sheet metals by upsetting the end of a headed cylindrical fastener thru hammering or squeezing.

Riveting

The process of joining metals by application of a high- temperature flame or electric arc in combination with a filler rod which is usually of the same composition as the base metal.

How is laminated tubing made?

By rolling impregnated reinforcing material on a mandrel

What is the main difference between high-pressure laminating and low pressure laminating?
