Tapping typically involves cutting threads into holes in metal sheets to create screw threads. As the name suggests, this is generally done using a tap, a tool designed to cut the threads into the metal. Tapping is essential for creating components that need to be fastened together with screws or bolts.
The precision of tapping ensures that the threads are consistent and can securely hold screws. This makes it a crucial process in manufacturing assemblies where parts must be frequently disassembled and reassembled.
Convexing
Convexing, or bead rolling, involves creating raised or indented designs on a metal surface. This technique is often used to add rigidity to a panel, create decorative features, or produce channels for fluid flow.
As such, convexing is used to fabricate automotive body panels, HVAC systems, and architectural elements. The process enhances the structural integrity of metal sheets without adding significant weight, making it ideal for applications where both strength and aesthetics remain vital.
Threading
Threading is the process of creating a helical ridge on the surface of a metal workpiece. This allows the insertion of screws and bolts. Fabricators carry out threading using various tools, including threading dies or taps. This technique remains crucial for manufacturing components to fit together correctly and can be easily disassembled if necessary. Hence, threading finds application in fabricating fasteners and fittings in machinery.
Counter Sinking
Counter sinking is the process of enlarging the top part of a hole to create a conical shape, allowing flat-headed screws or bolts to sit flush with or below the surface of the metal sheet. This is often done using a countersink drill bit.
Countersinking is essential for applications requiring smooth surfaces, such as electronics, automotive, and aerospace industries. This process improves the aesthetic appeal of the final component and ensures that screws do not snag or protrude. More to the point, snagging or interference could cause issues in tightly fitting assemblies or moving parts.
Laser Welding
Laser welding employs a high-powered laser to join metal pieces by melting and fusing their edges. The laser’s focused heat source enables deep penetration welds with narrow heat-affected zones. This minimizes the potential for thermal damage to surrounding materials.
Laser welding offers precision, speed, and minimal thermal distortion. This technique is especially useful in high-precision industries, such as aerospace, electronics, and medical, where clean and accurate welds remain vital.
