Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the work pieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. Wentworth's welding program is designed primarily for those who wish to begin a new career or enhance skills in their current role. Topics covered include an overview of welding, gas metal arc welding, and advanced arc welding.
Certified Welder Program - Through the American Welding Society (AWS), students will be assisted to pursue this certification as well as maintaining certification every six months. Testing can be completed on site and certified by Wentworth instructors. For more information about the certification, please visit http://www.aws.org/certification/CW/
- Length: 15 weeks
- CEUs: 6

An additional $250 per test plate for certification is not included in the tuition.
TWEL0110 Welding 1: Principles and Practices provide a course of instruction in welding, other welding processes, and cutting that will enable student to begin with the most elementary work and progressively study and practice each process until they are skilled. Both principles and practices are presented so that the student can combine the “why” and the “how” for complete understanding. Students at this level will attempt to do an AWS 3G or 4G plates. If completed, the student will be responsible for payment of such which will enable him to enter into the next level of welding. Flux Core Arc Welding (FCAW) and Shielded Metal Arc Welding (SMAW), commonly referred to as “stick welding,” are covered in this level.
TWEL0120 Welding 2: Principles and Practices present the fundamental theory and practice of Gas Metal Arc Welding (GMAW), commonly referred to as “MIG welding.” They will work on stainless steel and pipe materials and also to complete their 3G or 4G, unlimited fillet groove welding plate which would make them an asset to the industry. There will be instruction of plasma cutting and oxygen and acetylene cutting and burning for structural steel. In order to get to the advance level, both 3G and 4G must be completed. Students that have both 3G and 4G can acquire 6G pipe certification at their expense. Students will be eligible to take the next level of welding. Prerequisite: TWEL0110 Welding 1
TWEL0130 Welding 3: This course will require all students to be certified welders that have successfully completed all AWS Certifications (3G and 4G). Students will be required to learn inner shield and flux core, wire fed machines at a level from 125-400 inches per minute. This will enable the students to be a high commodity for the building of the infrastructure of the United States. This will also give the students the ability to study for the AWS certified welding inspector exam. Students will be eligible to take the next level of welding. Prerequisites: TWEL0110 Welding 1; Prerequisite: TWEL0120 Welding 2
Electives in Advanced Topics:
TWEL0140 Welding 4: The main goal of this course is to prepare the individuals who completed Welding (TWEL 0110, 0120, and 0130) to go out into the workforce and perform any task that is handed to them by the industry. The students will be able to fabricate on their own per the direction of the instructor. They will fabricate plates, beams and other structural fabrication (design build fabrication). For the purpose of this training students will be responsible to know the various codes and standards that are referenced in the Structural Welding Code-Steel book (AWS D1.1/D1.1M) by the American National Standard. This course is only offered to those students who have achieved the ability to perform SMAW and GMAW. If time permits, those students who have their D1.1 3G and 4G certification may be able to take the D1.5 bridge code of the State of Massachusetts Welding test. Prerequisites: TWEL0110 Welding 1; Prerequisite: TWEL0120 Welding 2; TWEL0130 Welding 3
TWEL0150 Welding 5: This course consists of Metal Fabrication Arc Welding. The welding procedure specification is AWS code D1.6. The process will include Base Metal: Austenitic Stainless Steel A240 type 304/304L, with thickness limits of 1/8th through 1 and 1/2" using the welding process of SMAW. The filler metal specification is AWS A5.4-2014 with the filler metal classification being E308/308L-17. Students will learn how to clean and prepare material prior to welding; also they will learn base metal preparation as per dictated by the WPS/PQR. The students will also learn the proper procedure for Flux Core Arc Welding (FCAW) stainless steel plate 304/304L. Prerequisites: TWEL0110 Welding 1; Prerequisite: TWEL0120 Welding 2; TWEL0130 Welding 3; TWEL0140 Welding 4
TCON0170 OSHA Training (Elective): OSHA 30-Hour Construction Courses are designed for construction foremen, superintendents and engineers, safety professionals, construction managers, plant engineers, construction inspectors and any other personnel responsible for workplace safety. Other topics include: OSHA Standards, OSHA Act, OSHA Recordkeeping, Multi-Employer Worksite Issues, Lockout/Tagout, Confined Space Entry, Personal Protective Equipment, Fire Protection and Prevention, Material Handling, Storage, Use, Disposal, Hand and Power Tools, Welding & Cutting, Scaffolding, Fall Protection, Cranes/Derricks, and much more. There are no prerequisites required for this course and the cost is $300.
Program Notes: Courses are awarded Continuing Education Units (CEUs), not college credit. Courses are designed to be taken one at a time and in sequence.
