Titanium tube welding blue can be how to deal with?
For non-essential bearing welds can be used, important welds only allowed silver and gold. If the surface of the weld after welding is gray, indicating that oxidation is too serious, it should be re-welded.
Welding should not be too anxious, welding a short section will stop, so that the welding of the weld and heat affected area will be fully cooled and then down welding, welding the surface of the weld after the silver that protection is very good, Golden yellow can also, blue oxidation is more serious,
Protection box can be made of stainless steel, the internal use of several layers of very fine stainless steel mesh to the argon gas flow evenly
Titanium welding the most important thing is to protect the problem, argon to use high-purity argon, welding gun to protect the hood, the back must also be argon protection, large parts or sheet, can not be the whole argon, in the back to special Do protective box
Titanium welding must be careful to prepare in advance to find a test board first welding, try and then in the product on the welding, but also pay attention to see argon gas meter, to prevent the middle of the argon interruption.
