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.

Tendency of the flux-wall guided transfer is the main symbol to judge usability-stability of the stainless steel covered electrode.

Usability-stability is all a pivotal problem of development of stainless steel covered electrode.

As the key vulnerable component of the sieve bend,elaborated the stainless steel welded curve screen plate principle of work,structure characteristic and practical application.
