The requirement for better quality of products and higher efficiency of production processes results in high-technological welding action. Inadmissible defects may extensively appear in the root of weld during manual welding with coated electrodes and semi-automatic with gas shielding, such as: slag inclusions, gas blowhole, lack of weld penetration. In automatic welding process with the use of flux, when observation of welding process is infinitesimal and current regulation of parameters is complicated, burn-through of contacts may appear. Therefore welders with the best qualifications are needed to make root of weld or affter cutting of root it is necessary to gouge.. Cutting of root and gouging overhead position is carried out in very difficult or after turning the construction which requires some other activities (e.g. stiffening the construction).

The problems can be eliminated by the use of ceramic backings protecting melted metal from the side of the root. Backings are mounted in welded construction by means of non-complicated systems, which is not a very labour-consuming process.

The advantages of using ceramic backings are as follows:

• reduced labor consumption thanks to elimination of whole variety of labour-consuming actions (cutting of root, the gouging, construction turning),
• welding actions can be run on one-side in technically convenient positions,
• possibility of employment of low qualified welders,
• elimination of weld defects in the root of weld and necessity of removing them,

It should be emphasized, that labour consumption constitutes 70-75% of typical welding construction costs and any reduction of it gives significant savings which considerably surpass the cost of purchasing ceramic backings.
