求翻译：对焊补前后试样进行了拉伸试验和冲击试验，其试验结果表明一次焊补使试样冲击韧性有所提高，并未改变试样的静载强度。是什么意思？

Tensile test and impact test specimens before and after butt fill their experimental results show that a welding repair improved the impact toughness of the sample, did not change the sample static strength.

Before and after welding tekst to supplement the tensile test and impact tests, the test results show that a solder joint supplement to the sample impact toughness increased sample and did not alter the static load strength.

Around the butt welding made up the test specimen to carry on the pulling test and the impact test, its test result indicated one time welded makes up enable the test specimen resilience to have the enhancement, changed the test specimen by no means the dead load intensity.

To sample before and after welding the tensile tests and impact tests, test results showed that improving toughness of welding samples, does not change the sample static load strength.
