The welding technology of titanium pipes was introduced comprehensively in this paper, including the welding ability analysis of titanium material, welding method, welding equipment, welder qualification, welding specification, welding procedure, welding inspection, re - welding of welded joints and measures for prevention of accidents etc.

It was suggested that improved process design, strengthening of "one removal and three injections" and selection of duplex steels or titanium material could bring the corrosion under control.

The promising prospects of building Baosteel into an advanced production base of titanium products in our country are revealed in this article.

Titanium Material Application in Salt Evaporation in Dingyuan Salt Mine;

This paper briefly introduces the leakage situation of titanium ammoinia strippers in domestic SNAM-type urea plants in recent years.

Corrosion resistant and highly intensive titanium centrifuges are selected to well meet the requirements.

One of key problems is, however, a poor wear resistance of titanium materials, to which the users desiderate a solution.

The wide application and important role of metallic titanium, titanium products and titanium\|based alloys in the major industrial sectors of the national economy, especially in the new and high technical fields, are described.
