The industries such as work, shipbuilding and other industrial circles.
Intensive small tube socket workpiece lesser for pitch and length is longer or the long tube socket of top tape elbow, such as boiler
The welding of small tube socket in header realizes that small tube socket automatic welding is always a problem.Not with boiler product parameter
Disconnected to be promoted, boiler header is also continuously improved with material grade, for high parameter boiler, 12Cr1MoVG and the above material such as P91,
P92 etc. has become the main material selection of header product.Since the small tube socket quantity of header product is big and dense distribution, small tube socket is axial
Spacing all very littles between radial direction, welding operating space is narrow, and accessibility is poor.Quality of parent material grade and welding structure complexity
Welding difficulty is increased, the guarantee of welding quality proposes higher requirement.Currently, small tube socket fillet welding in domestic boiler industry
The seam overwhelming majority uses manual welding, and welding workload is big, and large labor intensity, welding quality is affected by human factor,
