For the ultra - low - carbon austenitic stainless steel, using the process of strip electrode electroslag surfacing and the standardized heat treatment process of 600 MW nuclear vessels (615℃×29 h) , the mechanism of grain boundary phase eduction in weld metal is analysed deeply.

In this article, the principle of strip electrode electroslag surfacing is introduced.

This paper mainly expatiates the experimental analysis about the influence of the power characteristics,welding specification parameters,magnetic control technology and flux on the quality of the stainless steel strip electro-slag cladding.

Magnetic control of welder strip electro-slag surfacing;

Through a great deal of experiments the steady electroslag surfacing process with seamless cored strip is realized.

Magnetism conduct principle of trip surfacing was researched by simulating band electrode weld penetration state, analyzing the response of band electrode electric current to control magnetic field existence, the intensity, and the location conversion, and applying electronic techniques theory to analyze strip surfacing penetration control technique.

In order to improve the productivity, strip surfacing with higher welding currents and wider strips are adopted, which leaded to poor bead characteristics usually.
