Description
Technical field
The utility model relates to be taken over without bismuth stainless flux-cored wire used for gas shield welding welder, particularly takes over axis and can tune to built-up welding and the required flux-cored wire gas protection automatic soldering device of butt welding on adapter inner surface, outer surface, end face, regular shape fillet and conical pipe surface etc. perpendicular to horizontal plane.
Background technology
AP1000 steam generator low head is provided with entrance sleeve, discharge connection, manhole and PRHR and takes over, and takes over size from Φ
In296～Φ
In836.7 not etc.The inner surface of these adapters, the inner surface of adapter require the built-up welding austenitic stainless steel with the fillet that the end socket cambered surface is passed through mutually, to meet the anti-corrosion requirement in equipment running process.
For example, the as a whole forging of AP1000 evaporimeter low head, have respectively 2 discharge connection (Φ on end socket
Outward706.7/ Φ
In657.4), 1 entrance sleeve (Φ
OutwardΦ 836.7/ Φ
In799.2), 2 manhole (Φ
In471), 1 PRHR takes over (Φ
InΦ 296), be to guarantee the corrosion resisting property of product, each inner surface of taking over, locating ring and take over inner surface and end socket inner surface mutually the fillet at the place of passing through all need the built-up welding austenitic stainless steel, each need be not less than the preheating of 125 ℃ before taking over and welding.
