Acoustics and signal processing for welding process monitoring with acoustic sensing
The following PhD project is available for both domestic and international students starting in early 2019 to work with Prof Xiaojun Qiu at the University of Technology Sydney.
Value: $27,082 pa (tax-exempt) – a fee waiver may also be considered for an international applicant
Duration: 3 years, commencing by March 2019 in F/T PhD
Topic: Acoustics and signal processing for welding process monitoring with acoustic sensing
Enquiries: Prof Xiaojun Qiu
School/Centre: School of Mechanical and Mechatronic Engineering
Closing date for next intake
Australian Domestic students: 30th April
International Candidates: 15th January (contact me if looking for an earlier start date)
Gas Metal Arc Welding (GMAW) is an arc welding process widely used in industry and well suited to automatic welding. The proposed monitoring method is an urgent need identified by industry for improving process control and quality. Auditory cues have been found to be critical for expert welders to adjust the weld process and to maintain quality, but the mechanisms underpinning the process are not well understood. This project investigates the physical mechanisms of the GMAW sound generation, establishes an acoustic model that correlates the acoustic signal with other welding parameters, explores key acoustic features and identification algorithms for process monitoring, and develops a prototype GMAW process monitoring system.
The PhD scholarship is valued at $27,082 per annum for three years and funded through an ARC Linkage Project (LP160100616). An additional top-up scholarship of $5,000 per year may also potentially be available for outstanding candidates. The tuition fee waiver may also be available to exceptional international applicants.
The successful applicant will work on acoustics aspects and/or the signal processing aspects of the project, which include a study of the mechanism of welding sound, development of the acoustic model for the welding process, and conducting psychoacoustic ‘listening’ experiments to the welding sound, acoustic feature extraction and identification, multimodal analysis of weld phenomena, and data fusion based on the multimodal database for using multimodal features to improve the accuracy of welding process stability assessment. The successful applicant will gain industry experience on manufacturing processes and applications of acoustics and signal processing technologies.
The scholarship is available to local and international PhD students commencing with Faculty of Engineering and Information Technology of University of Technology Sydney (UTS) in 2019. To be eligible for this scholarship you must:
- be enrolled on a full-time basis in a PhD at the Faculty of Engineering and Information Technology
- be able to commence full-time study in Semester 1, 2019 (by March 31, 2019)
- satisfy entry requirements for a PhD program within UTS Faculty of Engineering and Information Technology
- have an undergraduate or master degree in the area of acoustics or signal processing or a related discipline
- demonstrate excellent academic results and research capability.
How to apply
Applicants should submit the following, by email, to Prof Xiaojun Qiu:
- cover letter (maximum 1 page) detailing any relevant experience
- curriculum vitae (maximum 4 pages) detailing educational background (with scores/GPAs), research experience, citizenship details, and any relevant prizes, awards, scholarships and publications
- copy of transcripts from relevant educational degrees.
