Steel pipes can be divided into two categories according to production methods: seamless steel pipes and welded steel tubes. Welded steel tubes are referred to as welded pipes(such as LSAW welded steel tube). welded steel tubes cutting methods include flame cutting, oxygen cutting, laser cutting and plasma cutting. In the cutting process of welded steel tubes, some small details that are ignored by us may have a great impact on the cutting effect and cutting efficiency. So what should we do when cutting welded steel tube? What should we pay attention to?
1. Before carrying out welded steel tube cutting operations, on-site inspections should be carried out to conduct stress analysis of the parts to be cut and analysis of stress change trends of the pipes after cutting, to effectively ensure the safety and maintenance of the pipeline system during and after the pipe cutting operation.
2. The workpiece processed by the cutting machine must be clamped firmly. Starting to cut if the workpiece is not clamped tightly will affect the cutting effect and the service life of the saw blade. When clamping the workpiece, the clamping should be stable and firm, and the protective cover must be installed correctly. After clamping, the machine should be turned on and checked for dry operation, and there should be no jitter or abnormal noise.
2. The power cord must be safe and reliable. It is strictly prohibited to pull it without permission. Be careful when placing the power cord so that it does not get cut off. The performance of the equipment must be carefully checked before use to ensure that all components are intact. Wear appropriate work clothes. Do not wear loose work clothes. Do not wear jewelry or have long hair. Do not wear gloves or operate with cuffs unbuttoned. Operators should cut off the power supply immediately when they are not standing behind the saw, have a power outage, take a break or leave the work site.
3. When replacing a new cutting blade or grinding wheel blade, do not use too much force on the locking nut to prevent the saw blade or grinding wheel blade from breaking and causing an accident. When cutting with a manual cutting machine, you should hold the handle of the cutting machine firmly and cut vertically with even force, and the fixed end should be firm and reliable. Do not clamp small workpieces or profiles with serious edges too tightly to prevent the saw blade from bursting during sawing.
4. In order to improve work efficiency, before sawing a single pipe fitting or multiple pipe fittings together, auxiliary clamping and positioning work must be done. Do not perform strong cutting operations. Wait until the motor speed reaches full speed before cutting. ; Do not release any hand from the saw or the workpiece or lift the arm when the saw blade is not stopped. Do not operate when the protective cover is not in place. Do not place your hands within 15 cm of the saw blade. Do not lean over or around the saw. When operating the machine, it is appropriate to tilt the body at an angle of 45 degrees.
5. If there is any abnormal sound, you should stop checking immediately; before repairing or replacing accessories, you must cut off the power supply and wait for the saw blade to stop completely before proceeding to the next step.
We should observe at all times during the operation of the pipe cutting machine, and eliminate small problems discovered during the cutting process in time to avoid major accidents caused by small problems and affect production efficiency.
