MECH ENG 4126 - Topics in Welded Structures
North Terrace Campus - Summer - 2022
General Course Information
Course Code MECH ENG 4126 Course Topics in Welded Structures Coordinating Unit School of Mechanical Engineering Term Summer Level Undergraduate Location/s North Terrace Campus Units 3 Contact Intensive - 10 days Available for Study Abroad and Exchange Y Assumed Knowledge MECH ENG 2020 Course Description This course presents the concepts behind welding and joining technology. These include welding and joining techniques, equipment and consumables, weldability of engineering materials, economics, standards, health and safety, testing and repair. The concepts are then applied to the design and fabrication of engineering components, process plant and structures. The importance of selecting the correct welding process and parameters for a particular application will be demonstrated by investigating several case studies. Since a weld/joint can have a profound effect on the performance of a component depending on the in-service conditions it experiences, the influence of service environment will be investigated. At the end of the course students should have the concepts to assist in the selection of processes and parameters to make appropriately designed, sound joints, fit for service in the operating environment.
Course Coordinator: Dr Reza Ghomashchi

Course Learning OutcomesOn successful completion of this course students will be able to:
1 Demonstrable knowledge of a range of welding processes, consumables and equipment and the capacity to select an appropriate welding process for a particular application ; 2 Analytical methods for understanding the variables for a range of welding process; 3 Recognise the importance of economic, environmental and occupational health and safety factors when considering the application of a welding process; 4 Explain the effects of welding on the properties of a range of materials including high strength steels; 5 Design welded structures for specific applications and environments 6 Explain the effects of welding on the residual stresses and distortion within the welded structure. 7 Outline the Australian and International Standards to which the design and manufacture of a particular structure must comply; 8 Identify the record keeping requirements for compliance to Australian and International Standards for welded joints, welded structures, welding processes, welding consumables, welding personnel and welding inspection; 9 Assess possible failure modes for the structure and their implications' 10 Apply and communicate the concepts provided to new situations and to read and understand professional articles on the subject;
The above course learning outcomes are aligned with the Engineers Australia Stage 1 Competency Standard for the Professional Engineer.
The course is designed to develop the following Elements of Competency:

Learning & Teaching Activities
Learning & Teaching Modes
Teaching will conducted through a series of lectures, practical session’s industry workshops.
Assignments and in-class quizzes are provided as part of the learning experience. Students are expected to enhance their knowledge, problem solving skills and understanding of the subject matter through completing the assignments and quizzes, so they are regarded as formative rather than summative. The assignments and quizzes are marked, with the mark contributing to the final grade for the subject to ensure that students actually do the assignments and quizzes and take them seriously. It also helps to assess whether the required graduate attributes are being developed.
The laboratory class is intended to provide students with some practical experience in using welding techniques. The examination is a summative assessment and is intended to assess the student’s knowledge and understanding of the course material and how it fits into the global engineering context.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
This intensive course will consist of 50 contact hours. Students are expected to match these hours with an equivalent of self-study hours.

The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
