Zusammenfassung:The utility model relates to stainless steel pipelines, in particular to an auxiliary stainless steel pipeline welding device. An inflation device for stainless steel pipeline welding protection comprises a gas inflow pipe, a gas outflow pipe and a connecting pipe, wherein the gas inflow pipe and the gas outflow pipe are the same in diameter, the inner diameter of the connecting pipe is matched with the outer diameter of the gas inflow pipe or the gas outflow pipe, the gas inflow pipe, the connecting pipe and the gas outflow pipe are connected together in sequence in a welded mode, gas outflow holes are evenly distributed in the pipe wall of the gas outflow pipe, a blocking sheet matched with a stainless steel pipe port to be welded in size is connected to the connecting pipe through threads, and a balance sheet is welded to the gas inflow pipe. The inflation device can be inserted into an argon pipe for inflation, and is simple, practical, convenient to use and feasible.
