Therefore, it is very suitable for welding the thin-wallconstruction of ferrous and nonferrous metals.
因此这种电源很适合于黑色及有色金属的薄壁结构件焊接。

The present technique is a new thin cutoff wallconstruction method by modifying the original method as to use flat drill bit instead of cross bit and adopt positive and negative circulating system.
It is essential to control assembly and welding deformations for large scale spheral tank with thinwall in order to guarantee spheral tank construction quality.
