Wet welding open days score 10 out of 10
While the sun was busy warming up the UK, staff at TWI North were busy hosting free
wet welding days for those who wanted to 'test the water' and try their hands at
the specialised skill.
Divers benefited by undergoing instruction and practising basic skills and techniques
in TWI's purpose-built wet welding facility - a 3m tank with a specialised extraction
hood. The tank is heated to approximately 23 degrees Celsius and maintains an excellent
level of visibility. Video, light and communications mean that the instructor can
constantly monitor divers' welding progress.
Open day training included 'bead on plate' for novice welders - focusing on the
importance of travel speed. For the more experienced wet welders, TWI instructors
concentrated on weld quality, and after welding examined the fillet welds and carried
out break tests to check for acceptable penetration. Wet welding theory covered:
- Set up
- Specific defects e.g. hydrogen cracking
- Problems associated with wet welding.
Visitors agreed that the wet welding open day delivered technical skill and information
in an enjoyable format - demonstrating a cost-effective way to begin training, and
showing how welders can take best advantage of facilities, materials and tutorial
resources. Here's what they thought:
"10/10 - will advise anybody to attend this facility," Neil Cockerham.
"All aspects of the day were fantastic and the lecturer was really helpful
in his instruction," John Fletcher.
"The course tutor was very helpful and had a lot of good advice,"
"Enthusiastic instructor who gauged answers to questions very well on both
basic and technical levels. A very enjoyable and informative session well worthy
of recommendation," Steve Fila.
The wet welding open days introduce a 10-day practical and theoretical wet welding
course at TWI where candidates can practise under the supervision of a coded wet
welding instructor with the opportunity to be coded on the final to D3.6M - an internationally
recognised welder performance qualification (WPQ). Theoretical instruction in this
course includes weld terminology, weld design, weld defects and applications; dry
practical exercises including bead-on-plate and fillet welds; comprehensive tuition
on underwater wet welding techniques and practical exercises; welding test to AWS
D3.6 Class B coding witnessed by Lloyd's Register of Shipping.
