Preliminary preparation

1. Material procurement: According to the design requirements, purchase the steel plate, welding wire and other raw materials that meet the standard to ensure the quality of the material. 2. Equipment inspection: Check the sound production equipment, including cutting machine, welding machine, straightening machine, shot blasting machine, etc., to ensure the normal operation of the equipment 3. Make production plan: According to the order requirements, make a detailed H-shaped steel production plan, clarify the time node of each process and quality control requirements.

Cutting and pretreatment

1. Steel plate cutting: The cutting machine is used to accurately cut the steel plate according to the requirements of the drawing to ensure the accurate size. 2. Edge treatment: Polish the edge of the cut steel plate, remove burrs and oxide, and improve the welding quality. Marking and classification: The treated steel plate is marked and classified to facilitate subsequent processing and assembly.

Assembly and welding

1. Assembly positioning: According to the design requirements, the steel plate is placed on the assembly platform for accurate positioning.

2. Welding preparation: Select the appropriate welding wire and welding parameters, and preheat and clean the welding parts.

3. Welding operation: Automatic or semi-automatic welding machine is used for welding to ensure that the weld quality meets the standard requirements.

4. Weld inspection: Weld inspection of the welded H-shaped steel, including appearance inspection, size measurement and non-destructive testing, to ensure the quality of the weld

Straightening and correcting

1. Straightening treatment: The straightening machine is used to straighten the welded H-beam steel to eliminate the deformation generated during the welding process.

2. Size correction: Size correction of the straightened H-beam steel to ensure that the size meets the design requirements.

Surface treatment and inspection

1. Shot blasting cleaning: Use the shot blasting machine to clean the surface of H-shaped steel to remove impurities such as oxide skin and welding slag

2. Anti-corrosion treatment: According to needs, H-beam steel is sprayed or hot-dipped zinc and other anti-corrosion treatment to improve the service life.

3. Quality inspection: Quality inspection of the treated H-shaped steel, including appearance inspection, size measurement, mechanical property testing, etc., to ensure product quality.

Packaging and delivery

1. Packaging protection: Package the qualified H-shaped steel and adopt appropriate protective measures to prevent damage during transportation. 2. Delivery arrangement: Arrange the delivery time and transportation mode according to the order requirements to ensure timely delivery to customers

Through the above process flow, we can produce H-shaped steel products with stable quality and accurate size to meet the needs of construction, Bridges, machinery and other fields. At the same time, strengthening the quality control and testing in the production process can improve product quality and market competitiveness.
