Description

Welding copper bottom structure

Technical Field

The utility model relates to a technical field specifically is a welding copper bottom structure at the bottom of welding copper.

Background

The best welding method is argon arc welding for copper and copper alloy, which can protect the molten pool from oxidation and gas insolubilization, reduce deformation due to heat concentration and ensure penetration of welding. Welding, also known as fusion, welding, is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, in a heated, high temperature or high pressure manner. The energy sources for modern welding are many, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic, among others. However, it is necessary to provide proper process measures, and because the resistance of copper is small, it is not suitable for resistance welding. The heat conductivity is strong, and the copper has high heat conductivity and needs a high-power heat source; and the welding can be carried out only by preheating the welding piece. The fluidity is high, the molten copper has good fluidity, and welding can be performed only at the flat welding position. If one-side butt welding is carried out at a spatial position, a backing plate must be added to ensure penetration and obtain good forming. The red copper is a material which is difficult to weld, and the welding method comprises gas welding, carbon arc welding, manual electric arc welding, manual tungsten electrode argon arc welding and the like. Can be selected according to quality requirements, process level and technical conditions.

When the existing welding copper bottom structure is used, the good splicing coincidence of a computer host server can be realized, and the good heat dissipation performance provides reliable operation for a computer, so that the heat dissipation welding copper bottom structure with excellent performance and reliable working operation is needed.
