Non-traditional methods such as CNC robotic spot welding deliver high accuracy, repeatability, and speed, making them suitable for ________ production.

What are the two main types of techniques used to join materials according to the passage?

Permanent techniques include welding, soldering, and brazing.

Where is spot welding extensively used?

MIG welding uses a continuously fed consumable wire electrode and an inert or active shielding gas (e.g. argon, CO₂) to create an arc with the workpiece.

What is one disadvantage of the MIG welding process mentioned in the passage?

Unlike welding, the base material in brazing does not melt.

The joint created by brazing is generally _______ than a welded joint and less suitable for high-load structural applications.

Which item is used to hold two or more objects together mechanically?

Nuts and bolts create a clamped joint by passing a threaded fastener through a hole in the sheet and tightening with a nut. The joint is ________-based and can be disassembled.

Pop rivets are used where access is only possible from one side, such as in aircraft panels, automotive trims, and consumer products.
