Titanium Weld Studs

Unique for its strength, lightness of weight and corrosion resistance

• Lightweight and high strength
• Corrosion resistant to chlorides, sea water & chlorine
• Excellent mechanical properties 
• Temperature vs. strength data
• Available in Titanium grade 2 & 5
• 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 Torx Screw Features and Benefits

Titanium Torx screws are characterized by a 6-point star-shaped pattern, also called a star drive, spined socket or hexalobular (ISO 10664). Where Phillips heads were designed to cause the driver to cam-out (prevent overtightening), Torx screws were designed resist cam-out. This feature allows titanium Torx screws to provide increased torque as well as better torque transfer between driver and fasteners. This feature also helps to reduce wear on driver bits.

Titanium Torx Screw Advantages

• Resistant to cam out (process by which a screwdriver slips out of the head)
• Titanium Torx screws are more difficult to strip
• Increased tamper resistance as a star driver isn’t as common
• Driver insert is less susceptible to damage when over torqued than Allen head

Titanium Vented Screw Features & Benefits

Titanium vented screws are ideal for use in high vacuum (UV) and ultra high vacuum (UHV) equipment, as well as other high pressure environments and applications where gas pockets can form. Center vented screws have a center bore drilled through their axis from the head through the threaded shank of the screw. This feature provides an outlet for the complete evacuation of trapped air and gas contaminants to be pumped away from blind-tapped screw holes, bottoms, sides and shoulders. In addition to vented screws, washers with vent grooves can be made to ensure the venting of the cavity found under the screw head.

Titanium Vented Screws Benefits
•  Enables faster, more efficient pump-down of HV & UHV systems
•  Eliminates virtual leaks•  Relieves pressure from blocked gases
•  Provides means to vent contaminants found in screw voids
•  Promotes higher system throughput and improved yield
•  Allows for constant pressure and temperature equalization

Titanium Vented Screws Are Available In:
Grades: Titanium Grade 2 and Titanium Grade 5
Styles:  Socket Head Cap Screw and Hex Head Cap Screw

What is a vented washer?
When a screw is tightened over a flat washer, or directly an application without a washer, volumes of gas can be trapped in the space and beneath the fastener head along the screw shaft. Titanium vented washers feature two bored canals on opposite sides of the flat face which provide an escape route for trapped gases.  

What is a virtual leak?
A virtual leak is comprised of gases that are trapped physically within a pocket with only a miniscule escape path from the trapped pocket of gas into the chamber proper.

Titanium Button Head Cap Screw Features & Benefits

Titanium button head cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face. Compared to a standard socket head cap screw, titanium button heads have a lower and wider profile. This can be useful when the clamping material is too thin to counter-bore.

Advantages

• Wide bearing surface for clamping
• Low profile head
