Petteri Yenstrom — New technology Kemppi "Reduced Gap"

Reducing the angle of groove can significantly increase the efficiency and productivity of heavy metalware welding. Traditional narrow-groove welding can be applied to most welding processes, but has the disadvantage — is practically impossible without specially designed equipment. To overcome this limitation, Kemppi has developed a new solution Reduced Gap Technology (RGT). This technology allows efficient and stable welding in narrow-groove without the need for special equipment or accessories for material up to 30 mm thick. RGT combines arc intelligent control of the high-tech power sources Kemppi; the wire feed mechanism and means of mechanization.
Key words: angle beveling, departure of the welding electrode throat, wire feed mechanism, productivity

Ryabchikov M. Yu., Ryabchikova E. S. — Strip heating control mode on the unit for continuous hot zincing through the use of neural network models

In the article the temperature modes control problems for heating and equalizing compartment of the continuous hot zincing unit. An approach based on the choice of rational modes through the use of the neural network models of heating strips and workspace is proposed. The complexity of creating such models associated with the variability of combined distribution density of the technological process original experimental data and also to the lack of technological information about real static temperature in the heating compartment is considered. The calculation possibility of such regimes based on approximations and extrapolations transient processes in accordance with working space temperatures in the areas of heating compartment is shown. The calculation results of the rational regime in heating compartment with uniform loading of the burner in the working zones are adduced. To implement the uniform loading of burners the schemes search algorithm based on a comparison of the plurality of generated randomly schemes and oriented to increase service life of radiant tubes is proposed.

The possibilities to solve the problem of metal discontinuity flaw type and size assessment with the use of an ultrasonic flaw detector with digital focusing of antenna array is shown. Owing to different digital image reconstruction algorithms the type of quite big discontinuities can be defined from a shape of their screen image; a real discontinuity size — from a screen image size. For discontinuity size comparable with a wave length, the two-dimensional Amplitude-Distance-Size-diagram is developed; the diagram enables discontinuity estimation to be done from the equivalent sizes of disk reflectors.
