Titanium alloys go all the way up to grade 38, and their characteristics and applications vary based on the alloy metals. When determining what grade of titanium or titanium alloy that would be right for your project, consider the environment it will be in, what the part will do, and the size of the desired part.

Common Metal Pipe Welding Techniques

Inert Gas Shielded Welding (TIG Welding)

This is one of the most regularly utilized titanium pipe welding methods. TIG welding uses inert gases (such as argon) to protect the welding area from oxygen and nitrogen contamination of the titanium metal. It can provide high quality welds, but at a slower speed.

Cladding Welding

In cladding welding, titanium metal powder is sprayed onto the surface of the titanium pipe, melting it, and fusing it with the substrate using a heat source. This technique works well for strengthening or mending particular sections of titanium tubes.

Electron Beam Welding

It is the employment of high-speed electron beam to locally heat and melt the titanium pipes to make a weld. It allows for high energy density welding with fast welding speeds and a small heat affected region.

Laser Welding

It uses high energy laser beams to melt and weld titanium pipes and tubes. It enables precisely controlled welding processes with the benefits of high speed and high quality.

Mechanical Joining for Metal Pipe

Riveting
Riveting is the joining of two metals by means of metal fasteners which mechanically lock them selves in position. This method of joining is especially applicable to the joining of highly stressed parts, the forming of a discontinuous joint, and in cases where the work is accessible from only one side. Titanium is being riveted with stainless steel, Monel, high strength aluminum, and titanium rivets by conventional techniques. With titanium rivets the driving time is increased 65% over that employed for high strength aluminum rivets. Rivets are cold-driven, and rivet holes require the maintenance of close tolerance to insure good gripping. When it is necessary to have flush-head rivets, dimpling is carried out at temperatures of 500 to 600°F (260 to 315°C). When riveting titanium to dissimilar metals or when riveting titanium with aluminum rivets, precautions must be taken to suppress galvanic corrosion.

Bolting
In this method of joining, the mechanical bond can be readily removed without destruction of the part. Titanium can be joined to itself or dissimilar metals with titanium bolts or with cadmium-plated steel bolts. With titanium bolts, the locknuts are plated with rhodium or silver to prevent galling and seizing of the nut to the bolt. Some increase in galvanic corrosion has been noted with the application of the cadmium-plated fasteners. Teflon coatings on the threaded parts have been reported to reduce greatly seizing and galling of titanium. Galvanic corrosion is also minimized by the corrosion resistance of the teflon.

Fabrication and Installation of Metal Pipe

Quality Inspection
After the arrival of the titanium pipe should be organized owner, construction manager, construction workers, quality inspectors, welding technicians, the pipe and valve parts material, specifications, quantity, quality and quality certification documents for inspection. The pipe must have the manufacturer’s factory certificate of conformity and quality certification. And should be measured one by one outside diameter, wall thickness, its outside diameter, wall thickness, ellipticity must meet the specification requirements. The inner and outer surfaces should be smooth, clean, and free of defects such as pinholes, cracks, folding, over corrosion.

Transportation
Titanium tubes should be placed according to the same requirements during transportation. In the lifting process, it is advisable to use nylon or synthetic fiber sling. If steel wire rope and unloading buckle are used, they should not be in direct contact with the pipe, and rubber or asbestos products should be used to isolate them.

Fabrication
The titanium pipe with good material, the smaller caliber, it is better to turn the bevel on the lathe, the lathe speed should be slower, and pay attention to cooling. Larger diameter (DN100 or more), it is appropriate to use the grinding machine to polish the bevel. The speed of operation should be slower, finished in several times, and pay attention to cooling. When close to the requirement, remove the pollution layer with a fine tooth file until the beveling requirement is reached. The bevel surface should be flat, no cracks, heavy skin phenomenon, and thoroughly remove burrs, melt ballast and oxides. The bevel angle should meet the welding process requirements, when the bevel processing is finished, pickling and cleaning within 50mm on both sides of the bevel. Then seal it with plastic cloth and mark it well. When grinding and cutting is used, the operation should be carried out in other places that meet the requirements. After the bevel processing meets the requirements, then move to the prefabricated special place.

Installation
Titanium pipe construction often encounters some small holes such as condensation discharge, emission, instrumentation taking source parts, which are difficult to open with conventional methods. Before the titanium tube welding, the size of the hole and the detailed and accurate location of the hole are drawn on the corresponding titanium tube. Use a lathe to drill many small holes along the centerline of the edge of the hole, the denser the better. After all the holes are drilled, use a copper hammer to lightly hit the center of the hole arc plate to detach it, and then use a special tool such as a fine tooth round file to process the holes to meet the requirements.
