Which electrodes need to be protected during welding?

1. Alkaline welding rod
Features: Alkaline welding rods (such as E5015, E5016) contain more fluorides and carbonates, and a large amount of harmful gases such as ozone, nitrogen oxides, etc. will be produced during welding.
Protective measures:
Wear a protective mask: Use a welding mask with a high-efficiency filter lens to prevent arc damage to the eyes.
Use a dust mask: Wear a dust mask that meets the standards to filter out tiny particles and toxic gases in the air.
Maintain good ventilation: Ensure that the welding area has good ventilation to reduce the accumulation of harmful gases.
2. Acid welding rod
Features: Acid welding rods (such as E6010, E6011) contain more silicates and titanates, and the harmful substances produced during welding are relatively small, but protection is still required.
Protective measures:
Wear a protective mask: Use a welding mask with appropriate filter lenses to prevent arc damage to the eyes.
Wear protective clothing: Wear special protective clothing to prevent welding spatter from damaging the skin.
Keep the work area clean: clean welding slag and ignition materials in time, and ensure that there are no flammable materials around.
3. Stainless steel welding rod
Features: Stainless steel welding rods (such as E308L, E316L) will produce chromium and nickel oxides during welding, which are harmful to the human body.
Protective measures:
Wear dust masks: Use dust masks with high-efficiency filters to filter out harmful particles in the air.
Use gas masks: Use gas masks in confined spaces or environments with high concentrations of harmful gases.
Regular physical examinations: Perform regular health examinations to ensure that you are not affected by potential damage.
4. Low-hydrogen welding rods
Features: Low-hydrogen welding rods (such as E7018) produce less hydrogen during welding, but protection is still required.
Protective measures:
Wear protective masks: Use welding masks with high-efficiency filter lenses to prevent arc damage to the eyes.
Maintain good ventilation: Ensure that the welding area has good ventilation to reduce the accumulation of harmful gases.
Use dust mask: Wear a dust mask that meets the standard to filter out tiny particles and toxic gases in the air.
5. Flux-cored welding rod
Features: Flux-cored welding rods (such as E71T-1C) will produce a lot of smoke and harmful gases during welding.
Protective measures:
Wear a protective mask: Use a welding mask with a high-efficiency filter lens to prevent arc damage to the eyes.
Use dust mask: Wear a dust mask that meets the standard to filter out tiny particles and toxic gases in the air.
Maintain good ventilation: Ensure that the welding area has good ventilation to reduce the accumulation of harmful gases.
General protective measures
Personal protective equipment: including welding masks, protective glasses, fire-resistant clothing, gloves, boots, etc., these protective equipment can reduce damage to the eyes, skin and respiratory system.
Keep the work area clean: Welding operations usually produce a lot of waste slag and ignition materials, so it is very important to keep the work area clean.
Avoid humid environments for welding operations: Welding operations require the use of electric current, and humid environments increase the risk of electric shock, so work in humid environments should be avoided as much as possible.
Ensure the safety of the power supply: Welding operations involve high voltage and high current, so the safety of the power supply is very important.
Fire prevention: Welding operations are prone to fire, especially the risk of fire caused by sparks and heat generated during welding, so attention should be paid to the surrounding flammable materials, and equipped with fire extinguishers and fire extinguisher usage skills.
Avoid long-term continuous welding: Long-term continuous welding will increase the fatigue and anxiety of operators, thereby increasing the risk of welding operations, so proper rest should be taken.
Check the safety of equipment and tools: Before performing welding operations, the safety of welding equipment and tools should be checked regularly to ensure that the wires, connectors, switches, etc. of the equipment and tools are not damaged or short-circuited.
Pay attention to communication information: When performing welding operations, effective communication should be carried out with other personnel, and ensure that no other personnel or animals around are harmed by welding operations.
Receive relevant training: Welding is a complex technology that requires training to master. Before performing welding operations, relevant training and guidance should be received, and relevant certificates or qualifications should be obtained.
Through the above measures, the risks of welding operations can be minimized and the safety of workers can be guaranteed.
