Table 3 The weight rating of the results.<br />
3. Results<br />
Figure 3 Analysis of the normal distribution of the error of the<br />
results of testing the strength of the weld.<br />
Figure 3 Analysis of the normal distribution<br />
When the testing strength of the weld data was analyzed and<br />
plot with the distribution of the error, the data distributed along a<br />
straight line was estimated that was normally distributed.<br />

Table 4 Test the strength of the weld.<br />
The results response variables of the strength test of the weld<br />
showed that the main factor was the power voltage of 4 spring area of overlap<br />
and size of welding wire. They influenced of the strength of the weld.<br />
- The amount of power at 45 amps was the best condition to test<br />
the strength of the weld.<br />
- The best condition of the pressure spring was at the level 60 daN<br />
- 0.9 mm in the area overlap areas of overlap at the overlapping<br />
area of the weld strength will rise as the area of overlap.<br />
- The size of the wire affect the strength of the weld to increase<br />
the size of the welding wire. It was found that the size of the welding wire is<br />
2.08 mm.<br />
This variable response has been test the strength of the weld to<br />
suggest the optimal conditions for the canned food to the strength of the welds<br />
are to a great extent, the amount of current. 55 amp electrical voltage spring 60<br />
daN areas of overlap and the size of 0.7 mm to 2.10 mm wire.<br />
Evaluation criteria used to score the highest points total of the<br />
four test results is to test the strength of the weld. Testing of the weld<br />
interface. To test the width of the weld. And the elongation of the welds. The<br />
optimum conditions in the canned food conditions in the 26 is<br />
1. Factor A (+): 55 amps of electricity.<br />
2. Factor B (0): the pressure spring 60 daN.<br />
3. Factor C (0): the space of 0.7 mm overlap.<br />
4. Factor D (+): the wire size of 2.10 mm.<br />
The results were weigh as follows.<br />
Test the strength of the weld was 10 points.<br />
Test results, the coordination of the weld to be 9 points.<br />
Test area of overlap is 10 points.<br />
Elongation of the test welds to 9 points.<br />
Table 5 compares the average test results.
