Self-Pierce Riveting vs Spot Welding

Following are some of the advantages of the Self-Pierce Riveting System:

• Self-Pierce does not require extensive monitoring equipment.
• Self-Pierce does not require costly electrode maintenance.
• When fastening galvanized steel, there is no need for smoke exhaust equipment.
• Coatings and adhesives are not destroyed in the piercing process.
• Self-Pierce allows the joining of two and 3 dissimilar materials with adhesive. Plastic included.
• Self-Pierce allows visual inspection and caliper measurement of fastening spot without destroying the part.
• When a Self-Pierce riveting head is attached to a robot arm, a rivet can be installed every 2-3 seconds. This includes the movement of the robot.
• The common spot welding practice of adding 20% - 30% more fastening areas because you are not assured of a good bond is not necessary with Self-Pierce riveting.
• The energy cost when using Self-Pierce riveting is the equivalent of running a 5 H.P. motor.
• The cost of Self-Pierce rivets is approximately 2 cents per rivet.
