As the versatility of Rykalin series mathematical models, carbon steel, stainless steel, titanium and other different metal materials' welding heat cycle curve can adopt these methods, the methods have great practicality
As for thin-sheet material, we could choose Hannerz, Rykalin2-D, Rosenthal mathematical model.
While the thick-sheet material, we should choose Rykalin3-D mathematical model.

Traditional river side-slope protection technologies are tend to emphasize the river flood control, water diversion, drainage, water storage, shipping, etc., so the side-slope protecting works are usually constructed by use of rigid hard materials such as slurry masonry or concrete.
Therefore, neither of the methods (that is, to use rigid material or decrease slope coefficient) is ideal.
Therefore, the eco-engineering measures which take plant as main engineering material have a good application prospect.

Introduction Laser direct metal deposition (DMD) is more and more envisaged for rapid freeform fabrication of fully dense or controlled porosity metallic materials, directly starting from computer-aided design drawings.
Additional investigations on 316L stainless steel have also been carried out to identify the material contribution.
A helicoïdal powder nozzle was used, where the powder material (45 µm -75 µm average grain size) is delivered coaxially with the laser beam, resulting in a dp ≈ 2 mm powder focus diameter, and with average mass feed rates Dm in the 1 g/min to 3 g/min regime.
Future investigations will consider systematically the correspondence between melt-pool volumes and aspect ratios, and resulting surface topographies, on Ti6Al4V and 316L steel, in order to (1) propose a material-dependent phenomenological model, and, in a second step (2) to be able to predict analytically surface finish.

Study and application on cutting technology of underground drifting blasting Xiantang Zhanga, Peng Zoub, Hongmin Zhouc, Hongli Wangd Shandong Provincial Key Laboratory of Civil Engineering Disaster Prevention and Mitigation, Shandong University of Science and Technology, Qingdao, Shandong 266590, China azzxhtm@163.com, bkdzoup@163.com, chongminzhou@163.com, dskdwhl@163.com Key Words: Drifting, Blasting parameter, Cutting； Abstract: Because of the weak borehole sealing and inadequate use of the initial free face, the higher investment and unsatisfactory blasting effect still exist in the mine tunnel excavation blasting.
Due to the influence of rock roadway section, the depth of wedge cutting has been extremely limited, while increasing the number of shooting and auxiliary time like the time of hide the gun, not only lowing the efficiency, but also increasing the consumption of human and material resources, so increasing the cost of rock drivage.Coupled with the blast hole jams rickety and the initial free surface is underutilized, tunneling excavation blasting efficiency of underground drift is 65% to 68%.
