Welding Program

The JATT Welding program is part of our 5-year work study program and continuing education for local Journeymen. The JATT teaches pipe welding and all its processes, with full time instructors available during the day and some evenings. Pipe welding is one of the highest skill sets in welding. Once apprentices have learned these processes your knowledge will be applicable to other areas of the welding industry. By the end of the JATT program apprentices will be a multi process skilled welder.

Welding processes taught by the JATT

  • SMAW - Shielded Metal Arc Welding
  • GTAW - Gas Tungsten Arc Welding
  • GMAW - Gas Metal Arc Welding
  • Mechanized Orbital Welding

Hours of Operation

While school is in session hours are 7AM to 8:30PM for all students and members of Local Union 72 Monday through Thursday.

During the summer months the welding school is open from 7AM to 5PM Monday through Thursday.


Approximately 75% of class time will be spent in the shop learning directly from our certified welding instructors.

  • 201: Intro to shielded metal arch welding, welding symbol interpretation, basic welding theory, and other foundations.
  • 402: Introduces pipe welding, earning UA certifications, and introduction to Gas Tungsten Arc Welding.
  • 503: Focuses on gaining certifications and introducing students to to GMAW and other specialized welding processes.

Applicants can show document prior training in welding from a trade school or technical school and work experience may be able to receive course credit for the 101 course. Applicants may also be required to demonstrate their skill ability at a weld test evaluation.

Advanced Weld Testing

The JATT holds bimonthly weld testing session to allow Local 72 members the opportunity to certify in 78 different welding processes. Obtaining additional and specific weld certifications increases the value and demand for these welders. Contractors do request welders with specific welding certifications.

Continuity Forms

Once a welding certification is achieved, the American Society of Mechanical Engineers rules requires welders to maintain continuity of their skills. Continuity forms allow welders to show that they have been utilizing their skills in the last six months. The required form lists the company the welder has been working for and the welding processes that has been performed within that time period

Failure to complete a continuity form for a specific certification within the six months requires welders to take a re-certification test at the apprenticeship school. The re-certification test is free for all members of Local Union 72.

UA Weld Re-Certification

Download the UA Weld Continuity form. The company foreman should complete the form and mail or fax it to JATT main campus office. The date on the continuity form should not exceed the expiration date on the welder’s UA Weld card. Continuity forms must be turned in every six months or less to prevent loss of your certifications.
