Cored wires are used in numerous welding processes with or without external gas or flux shielding. Submerged arc welding (SAW) with cored wires, seamed or seamless, for joining mild and low alloyed steel grades is a technique that has demonstrated clear advantages during the three last decades. Ever since its invention, the SAW process has evolved with one main goal: to combine quality with productivity. With low alloy wires, the benefits have already been clearly demonstrated and widely exploited. However, little has been written on SAW and cladding with cored wires for corrosion or heat resisting applications. Its extension to high alloy compositions brings corresponding benefits and adds some specific and unique features. This paper focuses on consumable specificities and on the quality and productivity features of SAW with CRA (corrosion resistant alloy) cored wires. It describes the potential as well as the limitations of this technique. Cored wires are now used for submerged arc welding of almost all stainless steels ranging from soft martensitic to super-duplex, and for a series of nickel base compositions as well as for cladding cobalt base alloys. Examples of industrial applications with austenitic, duplex, martensitic and heat resisting stainless steels are given to illustrate the potential of the cored wire solution. 13 Ref., 4 Tables , 25 Figures.

Выполнены эксперименты в стационарном и подвижном токоподводящем кристаллизаторе по изучению влияния глубины шлаковой ванны и ввода в нее разовых порций рабочего флюса на изменение тока наплавки. Установлено, что увеличение объема шлаковой ванны в стационарном токоподводящем кристаллизаторе не является технологическим приемом повышения ее температуры при неизменной величине напряжения источника питания. Разовая подача рабочего флюса при наплавке в подвижном токоподводящем кристаллизаторе может лишь кратковременно влиять на величину рабочего тока с последующим ее снижением до первоначального значения. Библиогр. 5, табл. 1, ил. 4. К л ю ч е в ы е с л о в а : стационарный и подвижной токоподводящий кристаллизатор; глубина шлаковой ванны; разовая подача флюса; ток наплавки

The technology of recycling the grinding wastes of metal cutting tool was developed using electroslag remelting, allowing producing a master alloy of the certain chemical composition. The structure and wear resistance of metal of the similar chemical composition deposited using two pilot flux-cored wires was investigated. A charge of one of the wires was prepared of the master alloy produced after wastes recycling, a charge of the second one was prepared of the appropriate ferroalloys. The investigations showed that the metal deposited using both flux-cored wires had similar structures and approximately the same wear resistance. It was established that the master alloy produced by utilization of grinding wastes production can be successfully used as a charge in surfacing flux-cored wires. 4 Ref. , 3 Tables, 3 Figures.
