I am a vacuum flask welding contractor, and I haven't found a job yet. Where do I need to recruit?

I wonder if the welding of vacuum cup involves argon arc welding, gas welding, vacuum brazing and spot welding. If such welding should be free of work, you can learn about some foreign spot welding or argon arc welding manufacturers in Beijing or Shanghai at the recruitment site. There are many, just look for them. I hope you can find a suitable job and get a reasonable salary.
