Welding and cutting machine
The H section steel plate should be checked again by our factory and shall be applied under the condition of up to design and specified requirements after checking. Steel plate cutting should be aimed at quality guarantee and material saving. For each process like plate cutting,H type assembly, components assembly and pre-assembly should be carried out by profession setting-out worker precisely on processing surface and assembly sample plates.To guarantee the accuracy of the components’geometrical dimension,tolerance of form and position, angle and contact surface,inspection is necessary by QC teams after setting out.In order to ensure the cutting quality,the surface of the ultra-thick plate is subjected to the surface carburizing hardness test before cutting.The laser cutting equipment is preferred for cutting.
H section steel assembly
The assembly process is set up on the imported H section production line.4 hydraulic positioning system press firmly against between the upper/lower flange and web plates in position. The adjust the parallelism of the flange plates and perpendicularity between flange and web plates and get them fixed after.
Automatic welding
The H section steel members will be hoisted into the gantry-type submerged arc automatic welding machine for welding.The welding process should be carried out in accordance with specified welding sequence and regulation parameters.Preheating, which uses the electrical heaters, is necessary for the ultra-thick plates of components.The set temperature shall be determined based on the specified one.Please see factory welding process documents for detail.
Welding robot
Stabilize and improve welding quality, and be able to reflect welding quality in numerical form; Improve labor productivity;Improve the labor intensity of workers;Reduced the requirements for workers' operational skills.
