Diploma in MIG/TIG/Oxy-Fuel Structural Welding — studying from Malta
Malta's rich heritage, including historic buildings, vintage vehicles and maritime craft, creates a niche for restoration and conservation work. Owners of classic cars, motorcycles and boats seek specialist workshops with knowledge of period engineering and materials. Restoration of historic architecture also requires engineers and technicians familiar with traditional construction methods and conservation rules. Opportunities tend to be found with specialist workshops, heritage organisations and private restorers.
Fees for Malta: €1,790 (Euro), with instalments and employer sponsorship available.

Questions from Malta
Is there a recognised professional body in Malta for restoration and classic vehicle engineering?
Malta does not have a single state-regulated profession for classic vehicle restoration. Vehicle registration and roadworthiness are handled by Transport Malta. SEIUM Institute's qualifications are private, not official state degrees, and are not accredited by any national body. Recognition is determined by employers, clients or the relevant body, so check these before enrolling.
What work could restoration engineers find in Malta?
Malta has a niche market for classic vehicle restoration, mainly through independent workshops, specialist garages and private collectors. Work is often built on reputation and practical craftsmanship. Whether a private online qualification adds value is for individual clients and employers to judge, so it is best to consider it alongside your hands-on experience.
Can I study this part-time with a workshop job, and is funding possible?
Yes. The programmes are fully online, taught in English and suitable for study from home, without needing a student visa. Hours range from 300 to 1,900 depending on the programme. Fees are payable in instalments, employer sponsorship is possible, and each student has an assigned technical tutor.
