What are the operating procedures of the circumferential seam welding machine?

Circumferential seam welding machine is an important automatic welding equipment, which is mainly used to complete the welding of various circular and annular seams.The circular seam welding machine is based on the principle of ordinary arc welding. It uses argon to protect the metal welding material. Through a large current, the welding material is melted into a liquid state on the welded substrate to form a molten pool, so that the welded metal and the welding material can achieve metallurgical bonding. Due to the continuous supply of argon during high-temperature melting welding, the welding material will not come into contact with oxygen in the air, thereby preventing the welding material from being oxidized. Therefore, stainless steel and ferrous metals can be welded.

Circumferential seam welding machine operating procedures

The operating procedures of the girth welding machine are important guidelines for ensuring that the welding process is safe, efficient and high-quality. The following are the operating procedures of the girth welding machine compiled from multiple sources:

1. Preparation before operation

Be familiar with the equipment:

The operator should be familiar with the basic structure, working principle and operating procedures of the girth welding machine.

Understand the meaning of the various functions, control buttons and indicator lights of the equipment.

Inspect the equipment:

Check whether the power cord and switch are normal, and ensure that there is no debris on the machine body and around it.

Check whether the relevant grounding wires and grounding devices of the welding equipment are reliable.

Check whether the cables, welding guns and welding parts are intact and there is no leakage or short circuit.

Prepare materials:

Confirm whether the required welding materials, tools, equipment, protective supplies, etc. are prepared in sufficient quantities.

Check whether the welding materials meet the requirements, including material, specifications, dimensions, etc.

Clear welding requirements:

Confirm the material, thickness, specifications, process and other requirements of the welding workpiece.

Select appropriate welding parameters and welding methods according to welding requirements.

2. Operation process

Prepare for startup:

Operate according to the equipment instruction manual and set the equipment switch to the "ON" position.

Check whether all parts of the equipment are operating normally. If there is any abnormality, it should be handled in time.

Workpiece clamping:

Fix the workpiece to be welded on the equipment to ensure that the workpiece is stable and flat.

Adjust the welding gun mechanism to the appropriate position according to the welding position.

Parameter setting:

Set the working parameters of the equipment according to the welding requirements, such as welding current, voltage, time, speed, etc.

Set the number of pulses, pitch, speed, etc. of the swing parameters (if swing welding is required).

Start welding:

After confirming that all settings are correct, turn the mode to automatic gear and pull the protective door.

Click the start button to start welding, and pay attention to the shape and size of the molten pool during the welding process.

Process monitoring:

During the welding process, pay close attention to the operating status and welding quality of the equipment.

If abnormal noise, smoke, odor, etc. are found, stop the operation immediately and check the equipment.

3. Post-operation processing

Shut down the equipment:

After welding is completed, turn off the power switch of the equipment and unplug the power plug.

Stop the gas and water sources (if the equipment needs it).

Cleaning the site:

Clean up the welding site and remove welding spatter and residues.

Wipe the outer surface of the equipment clean and keep it clean.

Equipment inspection:

Regularly check whether the various components of the equipment are working properly, and repair or replace them in time if any problems are found.

Regularly carry out comprehensive inspection and maintenance of the equipment to ensure long-term and stable operation of the equipment.

4. Safety precautions

Personal protection:

Operators must wear protective equipment, including welding masks, protective gloves and protective clothing.

It is prohibited to leave the site or carry out activities unrelated to welding during the operation of the equipment.

Electrical safety:

Ensure that the equipment is well grounded to prevent electric shock accidents.

It is prohibited to put your hands or objects into the equipment to contact live parts.

Fire and explosion prevention:

It is prohibited to perform welding operations near flammable and explosive items.

The welding site should be equipped with fire-fighting equipment and keep the passage unobstructed.

Other safety matters:

It is prohibited to make unnecessary adjustments and repairs while the equipment is running.

Comply with other safety regulations and precautions in the equipment instruction manual.

The operating procedures of the circumferential welder involve many aspects, including pre-operation preparation, operation process, post-operation processing, and safety precautions. Operators should strictly follow the procedures to ensure the safety, efficiency, and high quality of the welding process.
