Welding training programs cost $5,000-$15,000 at community colleges or technical schools. Programs may last two years and typically culminate in a certificate of completion. For example, Modern Welding School in Schenectady, N.Y., offers a three-month welding program for $6,000, which includes tuition, fees and materials.
Many trade and vocational schools offer welding courses as well, covering both traditional methods and newer technologies. AWS certification doesn't favor either approach. Welding certification is a pure meritocracy: Show up at the test site, prove you can do the job to appropriate standards, and you'll receive certification. The certification is good for one year but will be automatically renewed as long as you work in the same type of welding and submit documentary proof at six-month intervals.
