A braze material and processes for making and using the material, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material is composed of particles with melt-modifying constituents that are limited to the surfaces of the particles, yet are capable of sufficiently promoting the heating of the particles by conventional means and microwave radiation to achieve at least partial melting of the particles. The melt-modifying constituents are in the form of particulates embedded in the outer surface region of each particle. The particulates are formed of melting point depressant(s) and / or microwave coupling enhancer(s), are much smaller than the particle in which they are embedded.

Braze materials and processes for using braze materials, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material contains a plurality of first particles of a metallic material having a melting point, and a plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal. The nonmetallic material is more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material is present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation.

The invention discloses a pcb welding device which comprises a hollow pipe. One end of the hollow pipe is in sealing connection with a discharging device, and the other end of the hollow pipe is in sealing connection with a connecting part. The discharging pipe is in a funnel shape, and an end cover is detachably arranged on a conical part of the discharging device. A piston is arranged in the hollow pipe, and a copper pipe is arranged on the piston in a penetrating manner in the axis direction of the piston. The outer wall of the copper pipe is in sealing connection with the piston. The copper pipe penetrates the connecting part and can slide along a movable part, and a handle is arranged at the position, different from the end connected with the piston, of the copper pipe. A spring is arranged in the hollow pipe and located between the piston and the discharging device. The hollow pipe is sleeved with a shell, and the two ends of the shell are connected with the discharging device and the connecting part respectively. A heat insulation pad is arranged between the shell and the hollow pipe. A resistance wire is arranged between the heat insulation pad and the hollow pipe. A heat conduction insulation layer is arranged between the hollow pipe and the resistance wire. In the process of utilizing the device for pcb welding, operation standardability is easy to control, and welding quality is guaranteed.

A 3D printing nozzle for printing clothing, including a nozzle body, the nozzle body includes a nozzle with an open lower end and a nozzle connected to the lower end of the nozzle, the top of the nozzle is fixedly connected to a horizontal plate through a bracket, and the center of the bottom of the horizontal plate A motor with the output shaft facing down is fixedly installed, the lower end of the output shaft of the motor is fixedly connected with a rotating shaft, a through hole is opened at the center of the top of the nozzle, the upper outer side of the rotating shaft is fixed with a cam, and the outer wall of the frustum-shaped cylinder is vertically and uniformly fixed and installed There are several first cutting blades. The invention realizes the automatic cutting of solid wire rods through the L-shaped plate, and the rotation of the first cutting blade is driven by the rotating shaft to cooperate with the second cutting blade to gradually chop the cut solid wire rods so that they can be cut quickly when passing through the heating device. For melting, the rotating shaft drives the blades of the auger to rotate so that it can extrude the melted wire outward. The invention improves the melting speed and solidification speed of the solid wire, thereby improving work efficiency.
