The WEL-D’STRESS® system introduces residual stresses of compression and prevents the appearance of fatigue stains when traffic is intense.
Using the WEL-D’STRESS® hammer results in a very significant increase in the length of time before an aluminothermic weld shows signs of fatigue.
Less maintenance is needed – the life expectancy of welds in high traffic areas is identical to that of the rail.
As a result, maintenance costs are reduced and the system offers optimised life cycle cost (LCC).
There is increased availability of the infrastructure.
The WEL-D’STRESS® hammer is easy to transport and use.
The equipment is efficient and effective for welding on all types of rail and very high traffic networks.
The WEL-D’STRESS® hammer is a pneumatic system.
WEL-D’STRESS® can be used with aluminothermic welds from ambient temperature up to 300°C maximum.
The equipment has been designed to be extremely easy and intuitive to use.
The kit is compact and easy to carry. It comes in a strong case, certified IP67.
The WEL-D’STRESS® hammer can be used on all types of rail and very high traffic networks. This includes heavy haul lines and intense urban traffic networks, such as RER and Metro.
