What is the manufacturing procedure for hot rolled medium and heavy plates?

(1) When cutting, the material must be cut in strict accordance with the paper size. The machined surface must be filled with an appropriate amount of machining in accordance with the drawings.

(2) After cutting, the cutting edge shall be polished smooth.

(3) Before assembling the hot rolling medium plate, the welding seam of the welding seam shall be smoothed.

(4) If chamfering is required, the grooves must be laid in accordance with the requirements of the drawings before assembly, and the grinding shall be smooth.

(5) Before assembly, the material must be compared with the drawing size to prevent errors.

(6) Before assembly, the material must be "flattened and straightened" to prevent the paper size from increasing during assembly.

(7) Drawing process requires that the materials before welding must be assembled and welded in accordance with the technical requirements of the drawings.

(8) When assembling hot-rolled plates, they must be assembled in strict accordance with the drawing requirements. On this basis, appropriate welding shrinkage allowance shall be set to prevent the workpiece from ensuring the dimensional requirements after welding.

(9) During spot welding, the weld leg should not be too large, so as to avoid the influence on the formation of the weld during the welding process, but it must be ensured to prevent the strength from desoldering during the welding process. Spot welding must be considered at the welding position for the thin plate workpiece to be welded.

(10) After welding the assembly point of the workpiece, the workpiece must be "self inspected" before welding and then transferred to the welding position.

(11) The workpiece which is easy to deform by welding must be considered to be reinforced by process support.

(12) The welder must clean the welding position during the welding process to prevent defects during the welding process. When welding, the rib plate must have smooth transition.

(13) During transportation and processing, workpieces that are easy to deform must be reinforced with process support to prevent deformation.
