How is electron beam welding applied to wide plate welding?


Frequently Asked Questions

Huge time savings have been achieved on one of TWI's more unusual welding jobs: joining a stainless steel wide plate test specimen to carbon manganese steel crossheads.

One assembled specimen, destined for testing by the United Kingdom Atomic Energy Authority, stretched some 5m end to end, weighed 10t and called for use of TWI's 75kW electron beam welding machine and 150m3 vacuum chamber.

The aim of the wide plate test is to investigate the tearing behaviour under small scale yielding of a sample of simulated weld metal inserted into the test plate, again using electron beam welding.

Welding the plate to the crossheads was carried out in the vertical-up position and both seams were completed in less than 40 minutes.
