Using a laser, the robot can make highly accurate welds and position itself for each one a lot faster than it could if it were spot-welding in the normal way.
与传统方法相比，利用激光，机器人可以高精度高效率的完成焊接。

While Dave Gingery riveted his assembly together he does mention that welding is much faster.
虽然他的戴夫金格里铆接装配在一起，他没有提到焊接快得多。

In order to avoid the possible softening of HAZ in welding of RPC steel, laser welding is one of the best methods due to its faster heating and cooling rate and narrower HAZ.
