What are the safety operation procedures for manual arc welding, gas welding and gas cutting?

In fact, there is nothing safe or unsafe. Although I am young, I have been using electric welding for seven or eight years.

If gas welding is used, just pay attention to whether there is air leakage. Of course, it is not safe to burn yourself by gas welding.

Also, it should be noted that tempering means that the flame burns in the direction of the gas cylinder along the gas pipe, and it will explode if the gas welding is unattended during tempering.

Generally speaking, that's it. If you have to be official, you can only say so.

1, welders must undergo professional training, master the structure and performance of equipment and tools, and have the knowledge and performance of welder operation, be familiar with welder safety operation procedures, and only those who pass the examination and obtain the operation certificate can work independently.

2. Apprentices must be under the guidance and supervision of the master and can do general welding work. Those who failed the exam before the apprentice are forbidden to operate independently.

3, welder before work, must wear labor protection articles, for the use of tools, to do a comprehensive inspection, no problem can start work. 4. Non-gas welders are forbidden to use gas welding tools and welding. A "generalist" must pass the exam and issue a license before welding. 5. When working in a poorly ventilated place or in a tower or tank container, the welder should make a fire outdoors before starting work. 6. Before construction, check whether there are inflammable and explosive articles around. When hot work is carried out in inflammable and explosive dangerous areas, a hot work permit shall be obtained in accordance with the regulations. When hot work is carried out without a hot work permit, when working in towers and storage tanks, a work permit to enter the equipment must be obtained. 7. When working at heights, a "Work Permit at Heights" must be obtained. When cutting at high places, special personnel should take care of the ground or take other safety measures. The cut objects should be placed in designated places to prevent people from falling.

8. Before welding and cutting in the non-hot work area, welding can only be carried out with the consent of the fire department, otherwise hot work is not allowed. 9, the use of oxygen cylinders safety operation procedures

Oxygen cylinder is forbidden to contact with all oils, and the wrench that opens the oxygen cylinder must not be stained with oil wax.

B the oxygen cylinder should be more than 0/0m away from the fire source, more than 5m away from the acetylene cylinder, and more than 0/m away from the heating or other heat sources. The temperature of oxygen cylinder should not exceed 35℃.

C. When working in the open air in summer, oxygen cylinders must be placed in a ventilated place, covered with heat insulation materials, and it is forbidden to be exposed to the sun.

D the oxygen cylinder is absolutely forbidden to contact with the clamp wire or grounding wire of the electric welding machine. Oxygen cylinders are not allowed to be used as conductor rollers. E oxygen cylinders should absolutely avoid collision. Generally speaking, they are not allowed to carry or shoulder them. F. The gas in the oxygen cylinder is not allowed to be used up completely, and the residual pressure should be no less than 0.05Mpa. The gas cylinders should be stored separately and marked. G there must be two shockproof aprons on the oxygen cylinder, which shall be stored separately from inflammable and explosive articles. H. If the accessories of oxygen cylinders are defective and the valve screws are slippery, they should be stopped.

First, before opening the oxygen cylinder pressure reducing valve, open the damper to blow away the stolen goods. When opening and closing the air door and pressure reducing valve, people and heads should be on the side, and they are not allowed to face each other. After the oxygen meter is installed, tighten it with a wrench and screw the thread at least 5 times. 10 Safety operation procedures for using acetylene cylinders: a. Knocking and collision are prohibited.

B stay away from heat sources and electrical equipment, and avoid exposure in summer. The distance from the fire is generally not less than10m (when working at height, it should be a parallel distance outside the vertical ground).

Bottle valve freezes. Baking with fire is prohibited. If necessary, it can be thawed with warm water below 40℃.

D fixtures and shock-proof track brackets should be used for lifting and handling, and electromagnetic cranes and chains are strictly prohibited for lifting and handling. E. It is strictly prohibited to place it in a place with poor ventilation and radioactive rays, or on a rubber insulator.

F when the work place is not fixed and frequently moves, it should be installed on a special vehicle. When using acetylene cylinders and oxygen cylinders at the same time, care should be taken to avoid putting them together as much as possible.

G. pay attention to fixing when using to prevent tilting. Do not use it lying down.

H. The operating pressure shall not exceed 0.15mpa, and the gas transmission speed shall not exceed1.5-2.0m3/h ... 1. It is forbidden to exhaust the gas in the bottle, and the residual pressure shall not be lower than that specified in the table below.

The ambient temperature is 00 ~ 15 12 ~ 2525 ~ 40, and the residual pressure is Mpa 0.05 0. 1 0.2. I posted my last answer to others for adoption.
