As welding professionals, we strive for strong, sound welded connections that stand the test of time. However, the reality is that welds, like any manufactured component, can be susceptible to imperfections. These imperfections, often referred to as defects, can happen during the welding process itself or manifest later during the service life of the welded […]
There are four types of loading experienced by welds and welded structures. These types of loading are a function of the strain rate (the rate at which deformation occurs in a material due to an applied load) and the number of loading cycles experienced by the welded member. The 4 types of loading are: Static […]
Designing for fatigue is very different than designing for static loads. One of the biggest challenges is being able to estimate the loads, timing of the loads and duration of the loads. If you look at a bridge you have to estimate the number of vehicles going on the bridge every day, the weight of […]
The majority of industrial equipment and welded structural components are subjected to repeated fluctuating loads. These loads are typically of magnitudes that are within the elastic region of the material and well below its yield strength. This means that any deformation of the structure caused by the applied stress will then return to its normal […]
