Taking the Hong Kong-Zhuhai-Macao Bridge as the engineering background, this paper relies on the simplified formula and shell model analysis to investigate how welding residual stress influences the natural frequencies o...

A galvanized steel box installed near marine air might seem intact after five years... until a wrench blow makes a rusty hole. That''s why anti-corrosion strategies aren''t optional - they''re lifelines
The weld build up of wasted areas of the shell area in an ASME Section VIII Division I pressure vessel constructed of P-I Group 1 or 2 materials. Weld build up shall not exceed the lesser of one-half the
When trying to install the attachment, avoid welding to the base metal; because once welded, a post-weld heat treatment may be required.
This document provides design calculations for a distribution box.
The welding procedure should be supported by a welding procedure qualification record. The specification is to include the welding process, types of electrodes, weld shape, edge preparation,
In most cases, the residual stress distribution is very complicated. To solve these issues, this paper simulates the welding process of U-rib stiffened plates with changing welding parameters.
A ring-stiffened circular cylindrical shell is more economic than an unstiffened one in the case of external pressure, since these shells are very sensitive against buckling for this load.

The anti-corrosive method comprises the following steps of: step I, adding an anti-corrosive filler, a binder and a solder into an organic solvent, and mixing the substances uniformly and fully,...
UHT-82 contains the specific requirements regarding the performance of welding and qualification of welding procedures for these materials. Repair organizations are cautioned to review these
Here various components such as doors, hinges, locks and mounting brackets are assembled into the distribution box shell. In the end, the distribution boxes quality is inspected. Finally the completed
