It all starts with a vision of customer expectations. The weld design must comply with the code.
We enjoy the benefits of safe equipment, buildings, bridges and infrastructure. Engineers are trained to incorporate fail-safe designs to avoid structural failures or personal injuries. The root of welding code development is located in the history of welded items. Though today’s projects are “special” and the contract may specify “design-build” techniques, most welds are a common variety and repeated for decades. Design for code compliance is never discretionary.
The engineer who has the responsibility for design of a machine part or structural member as a weldment frequently operates under a severe handicap. Although the engineer has a mechanical background and academic training in materials and components, it is unlikely that adequate information was presented about the specific factors that enter into designs for welding. The designer needs to know how to use base materials efficiently, design for torsional resistance, design for stiffness and select the best suited weld joint for the purpose. The engineer also needs many other bits of practical information of which few are taught in schools or found in handbooks. Read more ... |
