It also includes offsetting and switching the position of the chemical injection nozzles (68) for allowing improved deposition in both directions, when operated in a horizontal mode.
It is the key to realizing high deposition rates MAG process with non-helium in shielding-gas mixture to acquire stable metal transfer mode in the region of high continuous current.
在连续大电流区间获得稳定的熔滴过渡形式才是采用无氦混合气体保护实现高熔敷率MAG焊工艺的核心问题。

The granite petrotectonic not only controlled the mode of ore deposition, but also influenced the space relations among the ore types in W-Sn metallogenic series.
