Application and Classification of Titanium and Titanium Alloy Welding Materials

Titanium andtitanium-alloy.html> titanium alloy materials, as the best among metal materials, have a series of incomparable excellent properties of other metal materials, so they have developed rapidly in recent years and have been rapidly and widely used in high-tech fields such as aerospace and military industry. The United States, Russia, Japan, China and other countries all over the world attach great importance to the research and development of titanium alloys, continuously develop new titanium alloy materials, and expand the application of titanium and titanium alloys. Due to the continuous deepening of research and the increase of product series, many titanium products, such as titanium wire, have increasingly entered the field of various civilian consumer products.

1. Classification

Titanium can be divided into pure titanium and titanium alloy according to whether it contains alloy elements, and titanium alloy can be divided into α titanium alloy and near α type alloy, (α+β) type alloy, and near β type according to its composition and room temperature structure. Alloys and β-type alloys. According to different properties, titanium and titanium alloys can be used to prepare wires with different requirements. The finished products of titanium and titanium alloy wire are generally hard (Y) and annealed (M).

2. Application

Titanium and titanium alloys have good corrosion resistance, high specific strength, non-magnetic properties, high biocompatibility, low impedance to ultrasonic waves, high sound transmission coefficient, hydrogen storage and good shape memory functions, etc. The excellent characteristics of important use value have produced important uses in many fields such as aerospace, petrochemical, medical and health, automobiles, construction, and sports and leisure products.

Titanium and titanium alloy wire, as an important variety of titanium material series, have made great progress in terms of output, specifications and applications. Generally speaking, titanium and titanium alloy wire refers to titanium products supplied in the form of discs, and some are supplied in the form of straight wires. In terms of diameter, the division of rods and wires is not strict, and it is also different from country to country. And in recent years, due to its continuous development, its variety has become more and more diverse, which provides more choices for its application in high-performance industrial products and consumer products.

Application and Classification of Titanium and Titanium Alloy Welding Materials

Titanium alloy has the characteristics of high hardness, light weight, corrosion resistance and high melting point, and is widely used in aviation, medical treatment, precision instruments, high-end machinery manufacturing and other fields.

The following is a brief introduction to the materials and types of titanium alloys used in welding:

According to the characteristics of titanium alloy, titanium alloy welding wire is mainly used in welding at present.

1. ERTi-1 titanium welding wire (pure titanium welding wire)

ERTi-1 is the purest unalloyed (or commercially pure-CP) grade. It is used where ductility is the first priority, such as explosive compounding, active bushings, expanded metals, and deep drilling. It is also Used in electrolysis, such as the production of sodium chlorate or the cladding layer of the anode bottom layer in chlorine gas. 

2. ERTi-2 titanium welding wire

ERTi-2 titanium welding wire is usually used to weld industrial pure titanium. Due to its good strength and welding properties, it is widely used in industry. Typical applications are welding of industrial pure titanium heat exchangers in chemical engineering, seawater heat exchangers, pressure vessels and piping systems, etc.

3. ERTi-3 pure titanium welding wire
Instructions for use: ERTi-3 pure titanium welding wire is relatively stable at room temperature. During the welding process, the liquid melting point and molten pool metal have a strong effect of absorbing hydrogen, oxygen and nitrogen. In the solid state, these gases has already worked with it. With the gradual increase of temperature, the absorption capacity of pure titanium welding wire also increases. It starts to absorb hydrogen at about 250°C and nitrogen at 400C. When these gases are absorbed, they will directly affect the embrittlement of welded joints. It is also an important factor affecting welding DC.

ERTi-3 pure titanium welding wire application: mainly used in aerospace, aviation, petrochemical, transportation, electronics, medical, tourism and other fields of fasteners, tools, equipment, etc.
 
4. ERTi-4 titanium alloy welding wire
ERTi-4 Titanium Alloy Welding Wire Supply ERTi-1 Titanium Welding Wire ERTi-1 Titanium Alloy Welding Wire ERTi-1 Titanium Wire These filler metals are usually used to weld industrially pure titanium. In these filler metals, the impurity elements gradually increase slightly from ERTi-1 to ERTi-4.

5. ERTi-5 titanium alloy welding wire
ERTi-5 welding wire, due to its relatively low cost and easy availability, is the most common and widely used alloy grade. It has a minimum tensile strength of 130,000 psi, good   and can be heat treated to higher strength and toughness. ERTi-5 titanium alloy welding wire is used for aerospace components, such as landing gear gears, wing spars, compressor blades, and its corrosion resistance is generally equivalent to that of ERTi-2.

6. ERTi-7 titanium welding wire
Product use: Used for welding reactors, storage tanks for storing acidic or alkaline substances, pressure vessels, crystallization evaporators, aircraft engines and other titanium equipment and parts.

Product features: Titanium and titanium alloys have the advantages of high strength, good plasticity, light specific gravity, high melting point, and good corrosion resistance.
