Description
Technical Field
The utility model relates to an anchor clamps technical field that brazes especially relates to an anchor clamps of brazing of adjustable weld clearance.
Background
Brazing is a process in which a brazing filler metal below the melting point of the base metal is heated to its melting temperature, and then the brazing filler metal flows under capillary action and fills the joint gap. Wherein the joint clearance has a significant impact on the mechanical properties of the brazed joint (including static load, fatigue, impact, etc.). Research shows that by controlling the brazing gap, the corrosion of the brazing filler metal to a parent material can be reduced, the mutual diffusion effect of the parent material and the brazing filler metal elements can be enhanced, and the joint performance can be obviously improved. For example, when a Ti-Zr-Ni-Cu brazing filler metal is used for welding SiC ceramics, strip-shaped silicide penetrating through the whole welding seam can be generated when the welding seam is too small, and meanwhile, a continuous and thick TiC layer is generated along the joint interface, so that the performance of the joint is seriously reduced. When the weld is too large, a large amount of intermetallic compounds of titanium increase, and hypereutectic compounds of titanium and zirconium are formed in the weld, resulting in a reduction in joint performance. Practice has shown that the choice of the optimum gap is related to a number of process parameters, including flux or shielding gas, base material surface finish, base material properties, braze metal properties, etc. Therefore, the reasonable joint clearance is selected to play an important role in improving the performance of the joint. However, determining a suitable brazing gap is a process that requires multiple trials. The technicians often choose to adopt the recommended values of the same type of materials for welding or perform a simple horizontal lap joint test due to the lack of a clamp capable of performing the test, and the optimal gap value is difficult to obtain when the recommended values of the same type of materials are adopted for welding. The simple horizontal lapping method has the defects that the joint gap is difficult to control and the obtained gap width is uneven, so that the mechanical property test result is inaccurate, and the gap is controlled in a stepless adjusting mode, so that the adjustment is difficult and the clamp structure is complex (because the welding seam gap is very small, the stepless adjustment is very difficult).
