Since weld distortion is a very costly problem for U.S. shipyards, the National Shipbuidling Research Program (NSRP) has embarked on a project to reduce weld distortion through innovative Induction ...

A.Well, the short story is that welding nearly always causes distortion (warping). When you make a weld, you are fusing red-hot metal to the base metal, and there is a zone of metal next to the weld ...

“Overview of Weld Defects” provides a comprehensive introduction to the most common varieties of weld discontinuities and distortion. It illustrates the causes of each of the twenty different weld ...

This paper focuses on an arc-welding robot scheduling problem, which is the problem of determining the sequence of welding operations while avoiding heat-caused distortion for the objective of ...

Welding thin sheet metal can be challenging because you need to obtain adequate fusion while preventing distortion and burnthrough. The key skill is to control the heat across the sheet metal to ...

Engineers must not only consider design and material requirements, but also should take the actual welding process into account. Part positioning and welding procedures affect weld quality. Designers ...

Overwelding is one of the most widespread problems in shipbuilding, causing significant distortion and associated rework costs in lightweight structural applications. In order to combat this problem, ...

Today the AweSim program at the Ohio Supercomputer Center announced it has been selected to develop one of 10 national industry projects under the DOE High Performance Computing for Manufacturing ...
