<b>{{Localize|Note}}: <section begin=reqNote /><noinclude></noinclude>An instructor is a must. Welding is a very critical and serious skill to learn and is not a home-type course. Welding essentially takes the place of bolts and rivets, and if not properly done, is most dangerous. Example: A trailer hitch not properly bond­ed, or machinery exposed to the strain of pull or weight, is an invitation to disaster.
