When stress distributions are examined, it is observed that the highest normal stresses occurred in the curved
lap joint with a radius of curvature of r=100 mm.
For the single
lap joints production, a 2 components structural epoxy adhesive (Axson ADEKIT A140 and H9940), under form of paste, was adopted.
The main conclusion is the fact that atmospheric corrosion has no critical influence on the
lap joint of galvanized sheet metals regardless of the plate topology and the brazing method.
Furthermore, all field joints were specified to be welded, utilizing bell and spigot
lap joints. Because elbows would require realigning the existing pipe to accommodate construction of the stations, it was decided that the design and pipe installation would be much simpler and cleaner with welded restrained joints.
Determine the impact of sequencing welding skill laboratory practicums for GMAW and SMAW mastery of AWS standards for AWS 1F (flat-position fillet
lap joint) welds.

A senior Boeing engineer said this month that the company normally did not expect that airlines would need to inspect the
lap joints for metal fatigue until an aircraft had completed about 60,000 flights.
"Boeing has asked operators of certain 737-300, -400 and -500 airplanes at or above 30,000 flight cycles to inspect certain
lap joints every 500 cycles or less," she said.
For the geometry of the elements, usually the
lap joint is used, and only seldom the add-on material.
