Test steel including Q345GJC - Z15 (wall thickness 70 mm), Q345GJC Z15 (40 mm) thickness, Q345C (28 mm flange thickness), welding position for horizontal column and column, column - liangping welding (including truss beam and flat welding flange), T Angle welding. Groove form and size according to the design requirements. After welding appearance and ultrasonic inspection qualified after sampling the mechanics and physics experiment was carried out.
Test results of the tensile strength of joint reach the parent metal tensile strength standard values, joint bending 180 ° no crack. The welding material and welding equipment technology conditions should comply with the national standards, excellent performance. Slag removal, air gouging, welding electrode drying thermal insulation device should be complete and effective.
