The process features
1) Automatic submerged arc welding is adopted in the main section
limbs and chord boom. It has high thermal efficiency, high
penetration, high production efficiency, while reducing the pores
and crack defects, increases the weld strength and the beautiful
2) We adopt carbon dioxide gas welding; it has heat concentrated, a
small welding line, high strength and resistance to rust and crack.
it can reduce tress and deformation, it has high strength and
resistance to rust and crack.
3) Shot blasting is used for masts to strength the hardness of
steel surface; enhance the paint adhesion and prolonging its life
