To address the problem of low welding precision caused by the poor real-time tracking performance of common welding robots, a novel seam tracking system with excellent real-time tracking performance and high accuracy is designed based on the morphological image processing method and continuous convolution operator tracker (CCOT) object tracking algorithm.
"Weld decay" which is intergranular corrosion in the heat-affected zone is a conventional and momentous problem during welding of austenitic stainless steels.
Sensitization as a serious and momentous problem during welding of stainless steel has not been completely prevented by conventional techniques such as reduction of carbon content (below 0.03 wt.%), addition of strong carbide formers (such as titanium, niobium or zirconium), and solution heat treatment.
The approach proposed in the present paper offers, for the first time, a complete solution to the problem of designing tubular FS welded joints against multiaxial fatigue loading.
The main problem of these alloys in fusion welding is the evaporation of the zinc during the welding process.
Increasing the strength, reliability and durability of welded structures is an important problem in welding engineering.
While Mr. Litan said it would be relatively easy to draw up a settlement that "fences Microsoft in from future violations," some state prosecutors have expressed concerns that Windows XP, which is to be marketed formally in October, creates a new set of legal problems by welding a variety of new applications, like video and audio player programs, into the operating system.
Selection of welding process is an unstructured decision problem involving multiple attributes (factors).
The need for a turntable to turn the locomotive around was therefore eliminated, although the initial designs were rejected by the operating department because of problems with welding technique.
The authors propose a technical solution to the problem of relieving residual stresses generated during welding NPP circulation pipes using an ultrasonic device.
