ABSTRACT
From this it can be seen that the process is very flexible, and this is one of its main attractions. However, it has to be remembered that the rate of joint production and the quality of the finished joint are directly under the control of the operator. It is an inevitable feature of this process that the rate of production and the appearance of the finished joints will be constantly varying and in direct proportion to the skill and experience of the operator concerned. Figure 5.1 shows the use of oxygen-propane flame heating during the repair of an electrolysis electrode. Note the presence of the filler material at the upper left.
