Manufacturing Technique

Welded steel pipe is a common method of joining metals, often used in construction, manufacturing, and piping engineering. Here are some basic knowledge and steps about welding steel pipes:

1.Preparation work: First, you need to prepare the required materials and tools, including steel pipes, welding rods or wires,

welding machines, welding masks, welding gloves, etc.

2. Clean the surface: Thoroughly clean the surface of the steel pipe to be welded to remove impurities such as grease, dirt, and

oxides to ensure welding quality.

3. Positioning and fixing: Position and fix the steel pipe according to the required welding position and angle. Clamps or other fixing devices can be used.

4.Heat treatment: For larger diameter steel pipes, preheat treatment can be performed to reduce welding stress and improve welding quality.

5. Welding method: Choose the appropriate welding method. Common ones include manual arc welding, gas shielded welding (such as MIG/MAG welding), TIG welding, etc. Choose the appropriate welding current and welding speed according to the specific

situation.

6. Welding operation: Contact the welding rod or welding wire with the steel pipe and apply an arc to melt and fuse with the surface of the steel pipe. During the welding process, a stable welding speed and a uniform welding current must be maintained

to ensure weld quality.

7. Post-weld treatment: After the welding is completed,necessary treatment is performed on the weld, such as grinding, removing welding slag, etc.

It should be noted that when welding steel pipes, you should follow relevant safety operating procedures, wear personal protective equipment, and ensure that the working environment is well ventilated. In addition, depending on specific needs and requirements, weld inspection and acceptance may be required to ensure that welding quality meets standards and requirements.

Packing & Delivery

Carbon steel plates are usually packaged in the following ways:

1. Steel strapping: Smaller size carbon steel plates are usually bundled with steel straps. Steel straps hold the steel plates in place to prevent them from slipping or deforming during transportation. In addition, labels can also be packaged on the steel belt to identify the specifications, quantity and other information of the steel plate.

2. Double-layer waterproof packaging: In order to prevent carbon steel plates from contacting the air and avoiding oxidation and rust, plastic PVC tarps are often used for packaging. It can effectively isolate air and moisture and maintain the surface quality of carbon steel plates.
