What is a henrob Rivet?
Providing fast, consistent high-quality joints, Henrob self piercing rivets and fastening systems are used extensively in many industries, from metal fabrication and construction to transportation and electronics.
How do self piercing rivets work?
The process starts by clamping the sheets between the die and the blankholder. The semi-tubular rivet is driven into the materials to be joined between a punch and die in a press tool. The rivet pierces the top sheet and the die shape causes the rivet to flare within the lower sheet to form a mechanical interlock.
Can you gas weld aluminum?
Summary. The gas welding processes most commonly used on aluminum and aluminum alloys are oxyacetylene and oxyhydrogen. Hydrogen may be burned with oxygen using the same tips as used with acetylene. However, the temperature is lower and larger tip sizes are necessary.
What is the difference between a blind rivet and a regular rivet?
Blind rivets, also commonly referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blind side) of the joint. Rivets have a two-piece construction; one is called the rivet body, shell, or hat and another is called the stem or mandrel.
What is the best gas for welding aluminum?
Pure argon
Pure argon is the most popular shielding gas and is often used for both gas metal arc and gas tungsten arc welding of aluminum. Mixtures of argon and helium are probably the next common, and pure helium is generally only used for some specialized GTAW applications.
Which filler rod is used to weld aluminium in gas welding?
Furthermore, the correct filler material must be selected. For instance, welding a 6061 alloy with a 6061 filler metal will result in weld failure. Instead, a 5356 or 4043 aluminum filler metal should be used when welding a 6061 base material.
Which type of rivet is mostly used?
Solid rivets may be the most common type of rivet. They are versatile and simple to install, and are often used in applications where reliability and safety are important. They can be made of aluminum, copper, brass, steel, titanium, and nickel-based alloys.
Why is it difficult to weld aluminium?
So why is aluminum so difficult to weld? This material is soft, highly sensitive and is insulated by a tough oxidized layer. While in its molten state, aluminum is susceptible to impurities, which can lead to porous, weak welds. Aluminum and its alloys have a great affinity for oxygen.
What is best to weld aluminum?
One of the most popular welding processes for aluminum is gas tungsten arc welding (GTAW), otherwise known as tungsten inert gas (TIG) welding. GTAW is a great process for aluminum because it does not require mechanical wire feeding, which can create feedability issues.

How does the henrob die changer work?
The Henrob Die Changer for robot-mounted riveting tools enables an upset die to be changed out automatically, without the need for operators to enter an automated cell. Automatic die changing allows for flexible manufacturing which lowers the overall cost of operations.
The basic self-pierce riveting process involves driving a rivet at high force through the material layers to be joined, into a die which causes the tail of the rivet to flare out and form a joint. 15 Starting condition Material clamped Rivet penetration Rivet insertion Insertion complete
