Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

An over component having a proximal end and a distal end and a rim having a proximal edge and a distal edge, wherein the distal end of the under component extending to a position flush with a proximal edge of the rim of the over component, wherein the distal end of the over component extending to a position flush with a distal edge of the rim of the under component. A central component, wherein the central component is coupled to the over component, and the over component is coupled to the under component

A method of pretinning a core wire for a guidewire having an elongate axis, comprising placing a ball of solder within a pocket in a soldering block; melting the ball of solder; holding a core wire over the ball of solder, with the elongate axis in a horizontal orientation; lowering a portion of the core wire into the ball of solder while maintaining the elongate axis in a horizontal orientation; removing the core wire from the ball of solder.

A roof laser brazing system comprises a side home position jig installed at each of opposite sides of the transferring path of the body in the brazing section, a roof-pressing jig detachably mounted on a handling robot, docked to the side home position jig, and that home-positions and presses the roof panel loaded on the opposite side panels, a brazing assembly mounted on at least one brazing robot in the side home position jig side and that brazes bonding portions between the opposite side panels and the roof panel using a laser as a heat source, and a grinding assembly mounted on the at least one grinding robot in the grinding section and that grinds brazing beads of the bonding portions between the opposite side panels and the roof panel.

A closed socket brazed joint assembly includes a first member, a second member with a first end having first and second faying surfaces, a socket in the first member that receives the second member with a faying surface with at least two portions separated by a first fillet. Before application of energy to the joint, there is a gap between the faying surfaces of the first and second members. A slug of brazing fill material is between the first end of the second member and at least one faying surface of the socket. Upon application of energy, the brazing fill material melts and flows from between first end of the second member and the at least one faying surface of the socket to fill the gap between the faying surfaces of the first and second members.
