A welder containing a weld part, a clamp and a number of tools that is for welding metal wires end-to-end to one another. The tools have a tool indicator that is either in complete or in non-complete condition, and can be processing tools used to finish the weld or testing tools allowing testing the weld once finished. Before starting the welding the first metal wire is held in the clamp. By that action all tool indicators are set to the non-complete condition. When a processing tool has been used, its processing tool indicator is set to complete. When the weld has passed the specification of a testing tool, the testing tool indicator is set to complete. When each processing and testing tool indicator is set to complete the clamp will open. In this case it is sure that the operator has done all necessary steps and checks on the weld.

A method of joining a surface-mount component to a substrate includes placing a piece of solder on top of the substrate and temporarily bonding the piece of solder to the substrate with at least one temporary bond. The method also includes placing a surface-mount component on top of the substrate with a bottom face of the surface-mount component facing the substrate. The surface-mount component has at least one lateral side. The method further includes positioning the surface-mount component with the at least one lateral side proximate the piece of solder, heating the substrate and the piece of solder to a joining temperature for a time sufficient for the solder to flow into an area between the bottom face of the surface-mount component and the substrate, and cooling the substrate and solder.

An ultrasonic bonding method of a conductor of an electric wire includes ultrasonically bonding strands forming a conductor of at least one electric wire using an anvil and horns. A first vibration mode of at least one of the horns is different from a second vibration mode of the other horns.

The present disclosure relates to a system of modular functional blocks that may be used to facilitate easy assembly of a welding head assembly in any one of a wide variety of configurations to allow for distribution of welding wire, gas, cooling fluid and other media throughout an interconnected assembly of the modular functional blocks. As such, the modular functional blocks can be mixed and matched into any desired configuration as needed depending on the welding process being undertaken. The modular functional blocks may be in the form of one or more different welding wire delivery blocks, gas delivery blocks, cooling water delivery blocks, shim plates, end plates, shield cup, cover plates, insulating plates, etc.

Disclosed are a joint of a copper terminal and an aluminium conductor and an ultrasonic welding method thereof. One spacing metal layer is added between the copper terminal and the aluminium conductor, and firstly, the spacing metal layer is fixed at a welding end of a base material by means of a manner such as electroplating, pressure welding, electric arc spray welding or electromagnetic welding, and the three parts are then welded together by means of an ultrasonic welding manner. The welding method is suitable for the welding of various joints, the electrochemical corrosion resulting from the potential difference between the copper and aluminium electrodes can be effectively reduced, and the mechanical properties of the joint can be improved.
