Abstract

The present invention relates to a kind of method for measuring connector fillet, changes originally by measuring stacked solder height, to judge the mode of welding quality, by under the microscope, being contrasted by the model of dimension limit, so as to determine whether qualification.The present invention objectively reflects the actual accumulation situation of solder, can more accurately judge weld strength, the fillet size of measurement is unique, and measurement result is reliable.

Description

A kind of method for measuring connector fillet
Technical field
The present invention relates to a kind of method for measuring connector fillet, overlap joint, the fillet of T connector being especially brazed.
Background technology
In vacuum brazing field, at overlap joint, T connector, the position that solder is accumulated on matrix is commonly referred to as connector pricker Angle.And fillet size, if that is, solder accumulate the circular arc to be formed radius or diameter it is too small, illustrate Joint intensity deficiency, fillet Radius or diameter are too big, then illustrate that corrosion of the solder to matrix is excessive.Usually accumulated at present by measuring the solder of fillet position Highly, the strength of joint of welding is judged, i.e. the size of K1, K2, K3 and K4 in Fig. 1.But these sizes cannot be very objective Reflect the strength of joint of welding, i.e., piling height is very high sometimes, but the thickness deficiency accumulated, and actual intensity is very low, and passes through The intensity that aforesaid way determines is high.
The content of the invention
Carried out the object of the present invention is to provide the strength of joint for realizing objectively reflection part welding, and then to weld strength It is accurate to judge.
The concrete technical scheme of the present invention is, a kind of the step of method of measurement connector fillet is：
(1) according to the use environment of soldering part and requirement, the limiting altitude of solder heap, i.e. maximum and minimum value are calculated, and It is fitted to the arc size of stacked solder；
(2) under the microscope, the side of connector is amplified to 50X；
(3) model of full-size and minimum dimension circular arc is chosen, is engaged under the microscope with fillet；
(4) it is qualified for welding if the radian value of fillet is between full-size and minimum dimension, otherwise, it is determined that being unqualified.
The present invention objectively reflects the actual accumulation situation of solder by measuring the actual circular arc value of solder, can be with More accurately judge weld strength.The measuring method of the present invention really solves the particular problem in production, utilizes new measurement Fillet method, the fillet size of measurement is unique, and measurement result is reliable.
Brief description of the drawings
Fig. 1 is former measurement position schematic diagram；
Fig. 2 is the measuring principle schematic diagram of the present invention.
Embodiment
As shown in the figure, a kind of method for measuring connector fillet comprises the following steps：
(1) according to the use environment of soldering part and requirement, the limiting altitude of solder heap, i.e. maximum and minimum value are calculated, and It is fitted to the arc size of stacked solder；
(2) under the microscope, the side of connector is amplified to 50X；
(3) model of full-size and minimum dimension circular arc is chosen, is engaged under the microscope with fillet；
(4) it is qualified for welding if the radian value of fillet is between full-size and minimum dimension, otherwise, it is determined that being unqualified.

Claims (1)

  1. A kind of 1. method for measuring connector fillet, it is characterised in that the method comprises the following steps：
