Welder training content
I. Training Outline
Welding operation is a special operation, and there is a strict training, assessment and evidence collection system for the qualifications of operators. Although they have mastered certain research, evidence collection and replacement skills after training, there are still many welders who have a weak sense of safety in welding operations and often violate the Welding Safety Operation Regulations. Because most welders have limited electrical professional technical knowledge and common sense of safe electricity use, there are many potential safety hazards in the welding operation site, such as the exposed terminal is not insulated as required, the exposed conductor of the electrode holder wire is not insulated as required, and the electrode holder wire is immersed in water and mud. It can be seen that eliminating the hidden dangers of accidents at the welding operation site is a skill that every welder should master. During the operation, we should not only ensure our own personal safety, but also ensure the personal safety of others. When welding, the welder should abide by the safety technical requirements and welding operation procedures to prevent electric shock injury and fire.
Second, the cause analysis of welding electric shock
1, lack of electrical safety knowledge.
2, in violation of safety operation procedures
3. The equipment is unqualified
4. Poor maintenance and management of electric welding machine.
Three, welder safety operation procedures.
Four, welding equipment and welding fire prevention measures
Causes of welding fire
When welding, there is both electricity and open flame. If the mind is paralyzed, the operation is improper, the system is lax, and the safety measures are not implemented, it is easy to cause a fire. The causes of welding fire can be summarized into three aspects: first, arc sparks; The second is power supply discharge; The third type is thermal conduction ignition.
Welding equipment should be kept in good condition. The insulation between the welding machine and the power cord should be reliable, and the welding wire should use copper core wire with sufficient cross section to ensure that the insulation will not be damaged due to overload during use. The wire is broken, so it should be replaced or disposed of in time.
Connect the welding wire with the welding machine and electrode holder with bolts or nuts, and tighten them to avoid inflammable and explosive articles.
In the process of arc welding, electrical equipment is often contacted, so welders should understand and master the structure and principle of electrical equipment related to this project, and master their basic knowledge of operation, maintenance and safe electricity use.
It is necessary to formulate various rules and regulations for the safe use of electricity, strictly implement the safety operation rules and the shift system, and establish a post responsibility system.
Five, construction welding safety operation.
