This study aims to solve the problem of weld quality inspection, for the aluminum alloy profile welding structure of high-speed train body has complex internal shape and thin plate thickness (2–4 mm), the conventional nondestructive testing method of weld quality is difficult to implement.

In order to solve this problem, the ultrasonic creeping wave detection technology was proposed. The impact of the profile structure on the creeping wave detection was studied by designing profile structural test blocks and artificial simulation defect test blocks. The detection technology was used to test the actual welded test blocks, and compared with the results of X-ray test and destructive test (tensile test) to verify the accuracy of the ultrasonic creeping wave test results.

It is indicated that that X-ray has better effect on the inspection of porosities and incomplete penetration defects. However, due to special detection method and protection, the detection speed is slow, which cannot meet the requirements of field inspection of the welding structure of aluminum alloy thin-walled profile for high-speed train body. It can be used as an auxiliary detection method for a small number of sampling inspection. The ultrasonic creeping wave can be used to detect the incomplete penetration welds with the equivalent of 0.25 mm or more, the results of creeping wave detection correspond well with the actual incomplete penetration defects.

The results show that creeping wave detection results correspond well with the actual non-penetration defects and can be used for welding quality inspection of aluminum alloy thin-wall profile composite welding joints. It is recommended to use the echo amplitude of the 10 mm × 0.2 mm × 0.5 mm notch as the criterion for weld qualification.

This article analyzes the concepts of experience economy and promotion of authenticity at The Venetian Hotel and Casino in Las Vegas by exploring the resort's tangible and intangible heritage use in design and marketing strategies.

This qualitative study conducts a content analysis of marketing material, historical documents, and site observations.

Visitors' active involvement, combined with The Venetian's use of tangible and intangible heritage, is used in creating an authentic themed experience. In addition, our study suggests that authenticity constitutes a key concept for today's hospitality industry.

This study centers on a single case study, and requires adjustments in order to be replicated. However, The Venetian represents one of the most prominent models followed by the hospitality industry worldwide.

This analysis provides a baseline for comparison among resorts that have theming but do not integrate it in the same way, or in general, to other professionals and academics considering themed experiences.

The manuscript centers on several aspects that are being debated in numerous fields, from business to sociology, such as customers' desire for authentic experiences through the creation of themed attractions.

This research fills a gap in hospitality marketing research into authenticity and themed experience by investigating how The Venetian Hotel and Casino uses the heritage of another, tourism-focused city (Venice) to promote itself. The investigation uncovers how themed attractions in hospitality create an experience-based involvement that centers on the authenticity of the theme (in our case cultural heritage) they replicate.
