• Features & benefits of titanium weld studs
• How a Titanium arc weld stud works

Titanium weld studs are available in a variety of fastener styles for manual (MIG, TIG) arc and capacitor discharge welding methods. Best known for being strong, lightweight and corrosion resistant, Titanium weld studs provide a secure, cross-sectional weld in single-sided access situations for a wide variety of extreme environments.

One property that stands out when compared to other metals is that titanium weld studs have the highest strength-to-weight ratio with a density of 4.51 g /cm³. As an example, titanium grade 5 is 4 times stronger than 316 stainless steel at nearly half the weight. This makes titanium weld studs ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods. 

Titanium weld studs are also unique among metals in the chemical processing industry for handling chlorine (wet) and chlorine compounds in aqueous solutions. Titanium is fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. As a result titanium weld studs are often using within the chlorine related industries such as pulp and paper and chlor-alkali / bleach.

Titanium is also an excellent material to prevent seawater corrosion. Because titanium weld studs can resists corrosion by seawater up to temperatures as high as 500°F (260°C) as well as survive at ocean depths over a mile below the surface, titanium is used throughout the oil & gas, desalination and marine industries.

The most common grades of Titanium weld studs are Grade 2 and Grade 5. Gain more insight on these by accessing our Grade 2 and Grade 5 overviews or by contacting our engineering experts.

Titanium Weld Stud Features & Benefits

Available in grade 2 and 5, titanium weld studs are an ideal way to securely attached fasteners in extreme applications where reaching both sides of a structure is impossible or undesired. These weld studs can be attached by a variety of welding techniques, such as MIG or TIG welding or they can be attached by automated welding guns using Arc or Capacitor Discharge (CD) technologies.

Arc and Capacitive Discharge (CD) Weld Stud Benefits

• Security: Unlike the peripheral weld used on a common bolt, the weld used to secure a weld stud fastener is a full cross sectional weld, so the full face of the fastener is welded in place for a strong, secure hold. And since there are no drilled holes – which weakens the structural integrity of the application – the attachment is even stronger.
• Speed: Installing a titanium weld stud is a fast and simple process with a most fasteners taking less than 1 second to weld in place. Plus there is no secondary work such as drilling, polishing or grinding.
• Simplicity: Weld studs require almost no special skills and minimal training and equipment is needed for installation. In addition, the equipment is also portable.
• Variety: Titanium weld studs are available in a wide variety of fastener styles including (but not limited to) fully threaded, partially threaded, full base, reduced base, long, tapped base, and shoulder thread to name a few.

Titanium Weld Stud Grades, Chemistry & Specifications

Titanium Grade 2  (Commercially Pure)

Unalloyed titanium; Commercially pure titanium is the most common grade of titanium utilized throughout industry due to its ease of availability and good properties.

Titanium Grade 2 Specifications: UNS R50400,  ASTM B 348,  AMS 4921, ASTM F 67, ISO 5832-2, Werkstoff 3.7035

Titanium Grade 5 (Ti 6Al-4V)

Known as the “workhorse” of the titanium alloys, Ti 6Al-4V, or Grade 5 titanium, is 2x stronger than titanium grade 2. This alloy offers high strength and light weight, useful formability and high corrosion resistance. Ti 6AI-4V finds many uses in the aerospace, medical, marine and chemical processing industries.

Titanium Grade 5 Specifications:  ASTM - B265, B348, B381, B861, F467 and F468, AMS - 4911, 4928, 4935, 4965 and 4967, MIL-T - 9046 and - 9047, Werkstoff 3.7165

Titanium Grade 7 

Grade 7 is the most corrosion resistant of all titanium alloys and is typically used in chemical processes and production equipment components. Similar to Grade 2, but with the addition of 0.12 to 0.25% palladium, Grade 23 has enhanced corrosion resistance to reducing acids and localized attack in hot halides. 

Titanium Grade 7 Specifications: ASTM - B265, B337, B338, B348, B363, B381, B861 and B862, Werkstoff 3.7235

Titanium Grade 23 (TI 6AL-4V ELI)

Titanium grade 23 or TI 6AL-4V ELI is an Extra Low Intersticial grade. This grade is similar to Grade 5, but because of the low intersticials, its mechanical properties are enhanced. This ELI grade is often found in more demanding medical device applications as well as industrial applications.

Titanium Grade 23 Specifications: 

ASTM - B265, B348, B363, B381, B861, B862 andF136, AMS - 4907, 4930 and 4956
