This video segment adapted from Pennsylvania College of Technology and WVIA examines welding, a profession that currently employs about 500,000 people in the United States. Due to an aging infrastructure that includes highway systems and bridges in need of maintenance and expansion, welders are expected to be in heavy demand over the next several years. The video demonstrates welding techniques, explains the consequences of bad welds and how to recognize when a bad weld has been made, and identifies different pathways to a welding career.
