How the project unfolded
1. The dilemma
The technical director is weighing up traditional welding against modern pressing. The time pressure is intense.
2. The test
A parallel test starts on several tanks. One team welds, the other presses with the TAVINOX system.
3. The result
After 10 days the pressing team is 3 tanks ahead. The client immediately switches the rest of the project to pressing.
