TWI now runs regular friction stir welding (FSW) courses in the UK. Demand for skills
in this innovative technology continues to increase as it finds more and more applications
in industry. The versatility of FSW technology makes it well suited to a wide variety
of industry sectors, including aerospace, automotive, marine, and computer hardware.
Friction stir welding is a solid-state joining process that creates high-quality,
high-strength joints with low distortion and is capable of fabricating either butt
or lap joints in a wide range of material thicknesses and lengths.
A rotating FSW tool is plunged between two clamped plates and the resulting frictional
heat causes a plasticised zone to form around the tool. The rotating tool moves
along the joint line, forming a consolidated solid-phase joint as it goes. Because
it’s a solid-state process, FSW eliminates many of the defects associated with fusion
welding techniques such as shrinkage, solidification cracking and porosity.
Fabricators are under increasing pressure to produce stronger and lighter products
whilst using less energy and less environmentally harmful materials, at lower cost
and more quickly than ever before. As a solid-state, low-energy-input, repeatable
mechanical process capable of producing very high-strength welds in a wide range
of materials, FSW offers a potentially lower-cost, environmentally benign solution
to these challenges.
Comments from the latest course:
'The course was well received with the strong emphasis on practical training coming
in for particular praise. Attendees enjoyed being able to use TWI’s state-of-the-art
equipment to make friction stir welds, and being given the chance to carry out inspections
to demonstrate the absence of defects.' Stephen Cater, course tutor.
‘It was a very interesting and detailed topic. Stephen has a vast knowledge of the
area and was willing to share everything.’ Candidate from the automotive
‘It was a very interesting course. I really enjoyed it.’ Candidate from
the automotive industry.
The course lasted three days: one to gain Foundation, followed by two more leading
to the Intermediate Award. At the end of the course, attendees were given the opportunity
to take an exam demonstrating that they had a level of knowledge of FSW in line
with the recommendations of ISO 25239.
The next FSW training courses are scheduled for February 2016 in the UK. Places
are limited so early booking is recommended.
