A system for manufacturing a drive shaft assembly comprises a welding apparatus configured to weld a tube to an end fitting to form the drive shaft assembly having an annular weld. A transport apparatus is configured to transport the drive shaft assembly away from the welding apparatus. A knurling apparatus receives the drive shaft assembly from the transport apparatus. The knurling apparatus is configured to knurl the weld of the drive shaft assembly. The knurling apparatus includes a pair of knurling plates having textured surfaces in facing relationship. One of the knurling plates is configured to move relative to the other of the knurling plates to roll the drive shaft assembly between the textured surfaces, thereby knurling the weld to improve an appearance and texture of the outer surface of the drive shaft assembly.

A portable rail weld milling machine apparatus comprises a metal frame that incorporates a motor with a rotary carbide tool that is able to lock to a rail or rails for stability. The apparatus houses the required guides and motors to maneuver the tool on a plurality of axes with computer numerical control (CNC). The CNC programming is able to control the carbide tool such that the welded rail can be milled to proper profile on the entire running surface, including the top, the field side, and the gauge side of the ball of the rail.

Embodiments relate generally to systems and methods for preventing arcing within a snap action switch, particularly by removing a portion of a contact carrier attached to a stationary contact. A method of forming a contact for use in a snap action switch may comprise welding a contact onto a contact carrier; trimming at least one edge of the contact carrier proximate to the contact; and installing the contact carrier into a snap action switch housing. Trimming the at least one edge of the contact carrier may also comprise removing flash formed during the welding of the contact to the contact carrier.

Method of trimming weld flash from a weld joint formed between a first component and a second component. The method provides a rotary shear tool having a rotary blade and a second blade. The second blade may be a fixed blade. The method further includes shearing the weld flash from the weld joint by passing the weld flash between the rotary blade and second blade of the rotary shear tool. Also provides a rotary shear tool for trimming weld flash from a weld joint formed between a first component and a second component. The rotary shear tool includes: a rotary blade; a second blade; and a mounting portion for mounting the rotary shear tool on a robotic arm.

A method of forming a golf club head, including placing a first portion of the golf club head adjacent a the second portion of the golf club head; welding the first portion to the second portion forming a first weld bead; injecting hot melt into an interior of the golf club head through an injection hole after forming the first weld bead; and welding the injection hole shut, forming a second weld bead.

A laser machining device includes a laser generating component, a light moving component, a gas source and a laser machining scrap removal device. The laser generating component generates a laser beam passing through an optical channel. The light moving component is positioned along a path of the laser beam to make the laser beam move along an annular machining path. The laser machining scrap removal device utilizes an internal flow path of the nozzle to increase the speed of the ejected airflow and reduce the pressure of a suction area. The gas source provides an airflow and is located on the laser machining scrap removal device in communication with the internal flow path of the nozzle. The laser machining scrap removal device induces suction on the laser processed area to assist in laser cutting/drilling processes by removing large areas of scrap, thereby improving the production speed and hole quality.
