How to clean the titanium welding wire

Prior to welding of titanium metal, it is essential that the metal's welding joints and weld wire should be free from the dust, grease, humidity and other severe pollutants. The presence of such unwanted materials tends to decrease the quality of titanium welding wire as well as its rust resistance nature. The welding wire is highly clean while packaging. However if the wire is containing any dirt it must be wiped using non chlorinated material before start using it.

In most cases, the cleaning by using acid may be recommended. The entire joint layers and base of plate at a distance of minimum one inch backside from the connection point must be cleaned. The basic pickled mill surfaces need just washed with traditional cleansers or detergent then rinsing with warm water and finally air dried. The wiping of welding connections and consecutive regions using non - chlorinatedsolvent like toluene, acetone or methyl ethyl ketone or others that are used o remove dirt from the cellulose sponges that do not allow any dirt to remain on the surface. The solvents usually influence in eradicating the grease oil. The solvent cleaning can be performed by using wire brushing however the steel brushes must not be used in the cleansing of titanium welding wire because it causes the possibilities of rust resistance degradation that is imposed on iron particles.

The light oxide layers as a result of heating in the temperature range from 600° to 800°F or 316° C to 427 °C for manufacturing purpose that can be eradicated by using brush made of stainless steel wire. The slight crushing, acid pickling are beneficial cleaning methods. The appropriate pickle shower for titanium welding wire in 35 volume% nitric and 5 volume% hydrofluoric acid are also recommended at the room temperature. The dipping of welding joints for one to fifteen minutes time is adequate.

To eliminate the acid, wire is washed with the cold water then hot water washing to provide drying and complete the sterilization of metal. The large scale and oxygen containing layers may be available resulted by the treatment under the large temperatures that can be eliminated by mechanical processes. The grinding or grit explosions are widely used. The liquefied caustic washes are significant though they need to be cautious for reducing the chances to combine with the hydrogen.

After the sterilization of titanium welding wire, the connection points should be secured cautiously. The dealing should be lower and welding should be industrialized after the cleaning. When the wire is not in use, its joints should be enclosed by paper or plastic material to prevent the deposition of dirt particles on the metal wire.

The titanium welding wire is covered under the AWS standards and chosen for the filler metal corresponding the features and constituents of titanium. Although the industrial pure levels and titanium alloys, the selection of welding wire material below of unit strength level is performed. The certain conditions may need for various metal levels to provide the required joint characteristics of welding wire.
