The Relationship

Micro-channel tube with submillimeter-diameter channels is a kind of newly developed heat transfer tube based on theory of micro-scale heat transfer. As the micro-channel tube has multiple welding points and work under high pressure condition, welding strength is one of the key problems for the extrusion process. This paper presented a new method in evaluation of the seam welding strength formed in the extrusion process. Firstly, FE simulation is carried out for the status of the billet in the welding chamber during the extrusion process. Then, thermo mechanical experiment is done for the relationship between the welding strength and three key factors. Combining the relationship with the numerical results, welding strength of the micro-channel tube can be evaluated. Pressure bearing test shows that the evolution method is reliable. The study is helpful for the optimization the extrusion process and improvement of the seam weld quality.

Abstract Alcoa C238 is a cold-finished aluminum wrought product developed for applications requiring postbrazing and welding strength. The alloy has good machinability and roll-threading characteristics. It has slightly lower corrosion resistance as compared to 6xxx series alloys. Alloy C238 has excellent welding and very good brazing properties. Initial applications include fittings and connectors that are brazed and/or welded. This product is also available in cold-heading rod that has been used to cold-form connectors. This datasheet provides information on tensile properties. It also includes information on corrosion resistance as well as machining and joining. Filing Code: AL-353. Producer or source: ALCOA Wire, Rod & Bar Division.
