In order to precisely and reliably predict the welding deformation during assembly process, all these factors must be taken into account in addition to the local shrinkage 4. Contributing factors to gap and misalignment are initial geometrical error, welding sequence, positioning, restraint and tack weld. The second is root gap and misalignment produced in the joint before or during welding. They are strongly influenced by heat input, shape of penetration, plate thickness and joint type. These three kinds of local deformations can be taken as inherent deformations 3. Basically, local shrinkage can be divided into three categories: longitudinal shrinkage, transverse shrinkage and angular distortion. The first is local shrinkage due to rapid heating and cooling in the weld zone. Generally, there are two major causes of geometrical error in the welded structure 2. Or for aluminum structures is possible change welding to brazing or bonding. Therefore, it is very important if it is possible reduce welding. Welding induced distortion not only degrades the performance but also increases the cost of a fabricated structure. Typically, these blocks are all-welded, thin-plate structures for example train door frame system.
For instance, the assembly process in train building essentially involves the joining of large blocks. Welding technology is one of the main joining methods and widely used in industries to assemble various products such as ships, vehicles, trains. Rolling stock manufacturers, systems suppliers and train operators are facing the technical challenge to meet the continuously rising requirements for safety, passenger comfort and barrier-free use for persons with reduced mobility 1. Increasing passenger volumes and a progressing use of public transport require highly reliable entrance systems. The input materials include metallurgical intermediary products that must meet requirements of the design (strength, toughness), technology (formability, weld ability), as well as economy. Due to its excessive segmentation and specific customer needs, it is impossible or causing complex problems and increased costs to produce aluminium frame doors without welding. Practical insight and inspiration from leading filmmakers like PES (Western Spaghetti Creator, Time Magazine’s #2 Viral Video of 2008), Dave Borthwick, of the Bolex Brothers and more! The accompanying website will include further content driven examples, indexes of stop motion software, a recommended film list and tools and resources for the beginner and intermediate stop motion artist, animators and filmmakers.During manufacturing of door systems for trains or vehicles is suitable selecting proper and suitable primer construction.
With tips, tricks and hands-on exercises, Frame by Frame will help both experienced and novice filmmakers get the most effective results from this underutilized branch of animation.

With over 25 years professional experience, industry veteran, Tom Gasek presents a comprehensive guide to stop motion animation without the focus on puppetry or model animation. In a world that is dominated by computer images, alternative stop motion techniques like pixilation, time-lapse photography and down-shooting techniques combined with new technologies offer a new, tangible and exciting approach to animation.
