To understand wiring harness welding, we must first understand what is wiring harness. The so-called wiring harness refers to the wiring components connecting various electrical equipment in the circuit, which are composed of insulating sheath, wiring terminals, wires and insulating wrapping materials. Wire harness is mostly used in various precision electronic equipment, such as automobile circuit, computer motherboard circuit, household appliances circuit, etc. There are three types of faults most likely to occur in this kind of wiring harness:

1)ZIRANSUNHUAI

排列5走势图1) Natural damage

Over the service life of the harness, the aging of the wire, the rupture of the insulation layer, the significant decline in mechanical strength, resulting in short circuit between the wires, circuit breakage, iron, etc., resulting in the burnout of the harness. Wire harness terminal oxidation, deformation, resulting in poor contact, etc., will cause electrical equipment can not work properly.

排列5走势图When assembling or repairing automobile parts, metal objects will crush the wire harness, causing the insulation layer of the wire harness to break; the wire harness position is inappropriate; the lead position of the electrical equipment is wrong; the lead of the positive and negative electrodes of the accumulator is reversed; when repairing the circuit fault, the disorderly connection and cutting of the wire harness can cause the abnormal work of the electrical equipment, or even burning. Bad wiring harness.

The first two kinds of faults are the most headaches for engineers and technicians. The selection of welding process is the most direct cause of such failure.

The traditional wire harness welding technology mainly includes fusion welding, fiber welding and pressure welding.

排列5走势图1) Fusion welding is a method of heating the workpiece interface to the melting state and completing the welding without pressure during the welding process. When welding, the heat source will rapidly heat and melt at the interface of the two workpieces to be welded to form a molten pool. The molten pool moves forward with the heat source and forms a continuous weld after cooling, which connects the two workpieces into one. After welding, the weld bead is formed by bracket joint of the wire harness, which has high resistance and greatly reduces the service life of the wire harness. In the process of welding, if the atmosphere contacts directly with the high temperature molten pool, the oxygen in the atmosphere will oxidize metals and various alloying elements. Nitrogen and water vapor in the atmosphere enter the molten pool, and defects such as porosity, slag inclusion and cracks will be formed in the weld during subsequent cooling process, which will deteriorate the quality and performance of the weld.

2) Brazing is a method of using metal material with lower melting point than workpiece as filler metal, heating workpiece and filler metal to temperature higher than and lower than the melting point of workpiece, wetting workpiece with liquid filler metal, filling interface gap and achieving atom diffusion with workpiece, so as to realize welding.

The weld formed during welding to connect two joints is called the weld. The two sides of the weld will be affected by the heat of welding, and the structure and properties of the weld will change. This area is called heat affected zone. Due to the difference of welding material and welding current, the phenomenon of overheating, embrittlement, hardening or softening may occur in the weld and heat affected zone after welding, which also degrades the performance of the welded parts and deteriorates the weldability. It is necessary to adjust the welding conditions. The welding quality can be improved by preheating the joint before welding, heat preservation during welding and heat treatment after welding.

3) Pressure welding is to combine two workpieces in solid state under pressure, which is also called solid state welding. Resistance butt welding is commonly used. When the current passes through the connecting end of two workpieces, the temperature rises because of the large resistance. When heated to the plastic state, the connection becomes one under the action of axial pressure.

The common feature of all kinds of pressure welding methods is to exert pressure during welding without filling material. Most pressure welding methods, such as diffusion welding, high frequency welding and cold pressure welding, do not have melting process. Therefore, there is no burning loss of beneficial alloy elements and the problem of harmful elements invading the weld seam, which simplifies the welding process and improves the welding safety and hygiene conditions. At the same time, because the heating temperature is lower than that of fusion welding and the heating time is shorter, the heat affected zone is smaller. Many materials that are difficult to weld by melt welding can be welded by pressure welding to form high quality joints with the same strength as the base metal.
