Moreover, the carbon equivalent of the medium carbon steel 42CrMo is about 0.834%, which means it possesses strong quenching harden tendency during welding, their welding process belongs to the typically dissimilar materials welding and is usually considered to be a great challenge [3-4].
Data available with regard to segregation aspects of K418 pertains mostly to cast material.
Experiments of laser welding of the above two materials were conducted on a 3 kW CW Nd: YAG laser materials processing systems with numerical control carrying out the spacial displacement of the assembly without any filler metal.

Introduction Theoretically, all materials are heterogeneous at a sufficiently fine scale.
In a classical local continuum approach many materials can be treated as homogeneous continua through separation of the scale of the problem under consideration and the lower scales of heterogeneities affecting physical processes.
The research has been carried out within the projects “Multiscale Numerical Modeling of Material Deformation Responses from Macro- to Nanolevel” (Croatian Science Foundation, 2516); “Multiscale Modeling of Heterogeneous Structures” (Alexander von Humboldt Foundation, Germany) and “Centre of Excellence for Structural Health” (EU IPA2007/HR/16IPO/001-040513).

Our problem studied is frequently encountered in the real-world warehouse of iron and steel enterprise which stores finished coils and semi-manufactured coils, such as hot-rolling back warehouse, hot-galvanize material warehouse, acid pickling material warehouse and acid-rolling back warehouse.
Similar problems also exist in other warehouses, such as stack yard in container terminal and material warehouse in dockyard.

In practical applications, the electronic label which stores the pig only individual identity, through to the electronic tag reads realizes information from slaughtered pig breeding to inheritance, traceability of pork processing raw materials in the process of information management, guarantee the processing chain of finished product can live one to one correspondence with farming, the slaughtering processing link with the upstream raw material production, and the downstream distribution, combining for pork products from farming to sales traceability of the whole security information System Function Food tracking and traceability of each link, not only will this part of the information, also gathered in front of the existing information, and all of the information will be marking on product labels, arrange another a link to use.
Pork products quality safety traceability of iot system set up, the whole process of data collection should include the whole production chain of pork products, according to the pork product traceability label on food packaging, through the website, cell phone barcode scanning terminals, bar code scanning guns, terminal can query to the origin of pork products raw materials, processing, logistics, transportation, sales, the corresponding source of information on pork products.
