Welding speed choice
This should be adjusted for the welding quality and production efficiency. If the
welding speed was faster, protection effect would not be good, cooling speed should
be bigger, the result is the welding crack’s forming would not be good and it would not
be well for welding forming. If the welding speed was slower, it would be very easy to
burn through the work piece and to make welding crack structure bigger and more
rough. In real situation, welding speed would not be faster than 30m/hour.
Welding wire
extension length
Welding wire extension length‘s increasing would be helpful for welding wire fusion
quicken and increase the production efficiency. If the extension would be bigger,
welding wire would be very easy to welding break, bigger splash, and make the
welding process not steady. Usually, the length of welding wire should be the ten
times longer that the diameter of welding wire
.
CO2 gas flow parameter choice
Mainly considering the effect of protection. And, inside corner protection would be
better than the outside’s.
Welding parameter list
Welding current and arc voltage will be the key point for the welding stability, welding
quality and production efficiency. To keep the good welding quality, it should be a good
collocation between welding current and arc voltage. It should be choosing basing on the
diameter of welding stick and production efficiency.
