Description
Technical field
The present invention relates to a kind of welding method, especially a kind of metal transfer welding method.
Background technology
Using the mixed gas of argon gas and carbon dioxide as protective gas and the activation polarization gas of use solid core welding wire
Body protection welding, using carbon dioxide as protective gas and using plus scaling powder welding wire electric arc welding, without using protective gas
And using self-shield with plus scaling powder welding wire self-shielded arc welding connect it is equal in, transfer manner of droplet is as spray transfer form.
In spray transfer form, due to arc heat, welding wire front end melts, and becomes particulate, and transition is carried out to molten bath.Metal transfer
Welding manner is then in molten drop short circuit, and digitlization electric power outputting current goes to zero, while the pumpback campaign of welding wire helps molten drop
It falls off.Therefore metal transfer welding procedure can efficiently reduce splashing relative to conventional welding procedure.
