It is close to inner tubal wall, and flow down can not be continued.Liquid state of molten pool metal is fully fused with stainless steel side mother metal, reduce folder
The weld defects such as slag, solder skip, rosin joint occur.Ensure stainless steel side weld quality and welding uniformity and stability.Welded in tubulation
When connecing, water is flowed into from water inlet and padded, and is flowed out by delivery port.The partial heat that pad absorbs when tubulation welds is taken away, is made
It must pad and be in low-temperature condition all the time, ensure that pad will not ensure that tubulation welding is prolonged suitable because working long hours and scaling loss
Profit is carried out.
Nozzle is protected using water cooling, water takes away the heat for protecting nozzle to absorb during welding when flowing through cavity, ensure protection nozzle temperature
All the time it is in low-temperature condition.Solve because of consumable electrode activity（Or inertia）Gas shielded arc welding（MAG/MIG）When, protective atmosphere it is cold
But effect does not have pure carbon dioxide good, causes the easy scaling loss deformation of traditional welding gun protection nozzle, and influence welding quality, can not be for a long time
The problems such as welding and low production efficiency.Simultaneously as water cooling protection nozzle temperature is low, protection can not be bonded in by welding caused splash
On nozzle, splash easy Automatic-falling, will not influence asking for welding quality and production efficiency because welding gun blocks when solving welding
Topic.
