Occupational safety training for operating electric welding machines

1. Overview of Electric Welding Machines

a. What is an Electric Welding Machine?

An electric welding machine is a device used in the process of welding metals. Welding metals involves joining two or more pieces of metal by heating them to a high temperature until they melt and then allowing them to cool to form a solid bond.

An electric welding machine is an electronic or electromechanical device used to generate the heat required for welding metals. It works by producing a strong electric current through a specific point on the metal surface, generating enough heat to melt the metal, which then solidifies to create a welded joint. Electric welding machines can operate on single-phase or three-phase power, depending on the machine type and specific application.

There are various types of electric welding machines such as stick welders, TIG welders, MIG welders, and plasma welders, each with its own applications and features. Electric welding machines are commonly used in industries such as construction, metal fabrication, automotive repair, and other applications requiring metal joining and repair.

b. Applications of Electric Welding Machines in Manufacturing

Electric welding machines are essential tools in many manufacturing processes. Some common applications include:

• Metal fabrication and manufacturing: Electric welding machines are widely used in fabricating metal components such as pipes, sheets, structural frames, and other metal products.
• Automotive manufacturing: In the automotive industry, electric welding machines are used to weld parts of vehicles such as car frames, door hinges, and exhaust systems.
• Electronics manufacturing: In electronics production, electric welding machines are used to weld electronic components on printed circuit boards, including surface-mount and through-hole soldering.

• Construction: In construction, electric welding machines are used to weld steel frames, iron doors, railings, and other components in buildings.
• Maintenance and repair: Electric welding machines are also used in repair and maintenance activities to rejoin or replace damaged machine parts.

c. Industries Using Electric Welding Machines

Electric welding machines are used across various industries, including:

• Metal Manufacturing: Possibly the industry that uses electric welding machines the most. They are used to weld metal components such as pipes, sheets, steel structures, and other metal products.
• Automotive Manufacturing: Used to weld vehicle parts such as frames, door hinges, and other metal components.
• Electronics Manufacturing: Used to weld electronic components on printed circuit boards and during the production of electronic devices.
• Food and Beverage Manufacturing: In some cases, electric welding machines are used to produce and seal food packaging and containers.
• Energy Industry: Used to work on components and structures in the energy sector, such as welding pipelines or energy supply systems.
• Shipbuilding and Marine Industry: Used to weld parts and structures of vessels and marine products.
• Construction: Used to weld steel frameworks, iron doors, railings, and other metal components in construction projects.
• Industrial Equipment Manufacturing: Machines and industrial equipment are assembled and welded from separate components.
• Aerospace Manufacturing: Used in producing and maintaining aircraft and spacecraft components.
• Water and Wastewater Industry: Used to weld parts of water treatment systems and pipelines.

In conclusion, electric welding machines are versatile and essential tools used in numerous manufacturing sectors for welding and joining metals.

2. Overview of Safety Training Courses for Electric Welding Machine Operation

a. What is Occupational Safety Training?

• Occupational safety training for electric welding machine operation consists of lessons that raise awareness on preventing workplace accidents. Workers who work directly with electric welding machines belong to Group 3.
• The safety training course helps workers recognize and prevent hazards, reducing the risk of workplace accidents during their tasks.

b. Training Duration

Initial Safety Training

• Total training time is at least 24 hours, including assessment time.
• 8 hours of theoretical lessons on policies and labor safety regulations
• 8 hours of theoretical lessons on basic occupational safety knowledge
• 4 hours of theoretical lessons on specialized training content
• 2 hours of practical lessons on specialized training content
• 2 hours of final theoretical exam

The safety training center schedules sessions based on worker availability. Typically, there are 6 sessions over 3 days if the company can allocate continuous training time.

Periodic Safety Training

• Before the occupational safety card expires, workers must undergo periodic safety training, with training time of at least 50% of the initial training duration.

Explanation: Total periodic safety training is at least 12 hours, including assessment time. Upon completion and passing the exam, the occupational safety card is renewed.

c. Training Content

d. Occupational Safety Card

After completing the safety training and passing the exam, workers are issued an Occupational Safety Card (commonly called Occupational Safety Certificate Group 3).

The Group 3 safety card shows the worker’s full name, date of birth, job, specific work environment, training duration, red seal, and signature confirming completion of the course.

According to Article 24, Clause 2 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must sign and stamp the safety card for the Group 3 worker after completing the training from a certified training unit and passing the exam.
• If the worker is freelance or temporary, without a labor contract, the training unit must sign and stamp the safety card after the worker completes the training and passes the exam.

3. Hazards When Operating Electric Welding Machines

Operating electric welding machines can pose many hazards if safety rules are not followed and proper training is not provided. Below are some common hazards when operating electric welding machines:

• Electric Shock Risk: Electric welding machines operate with high current, so users must always follow electrical safety rules to avoid electric shock. This includes using protective equipment such as insulating gloves and ensuring that electrical devices are not damaged or faulty.
• Fire and Explosion Risk: Welding can produce sparks and high temperatures. If not properly controlled, it can cause fires or explosions, especially near flammable materials. Using fire-resistant materials and following fire safety rules is essential.
• Infrared and Ultraviolet Radiation: Welding processes can generate infrared and ultraviolet radiation, which can harm eyes and skin. Users should wear appropriate protective goggles and clothing to protect themselves.
• Toxic Fumes: Welding can produce toxic gases from metals or welding additives. Users need to work in well-ventilated areas or use respiratory protection equipment.
• Accidents with Welding Tools: Welding tools can be heavy and sharp, posing high accident risks. Users should always follow safety rules when handling these tools and receive proper training.
• Noise Impact: Electric welding machines often generate high noise levels. Users should wear hearing protection, such as noise-cancelling headphones, to protect their ears.
• Machine Malfunctions: Welding machines may malfunction or break down. Users should know how to operate machines safely, check them before use, and report any issues to supervisors or technicians.

To ensure safety when operating electric welding machines, users should receive proper training, follow safety rules, and use appropriate personal protective equipment.

4. Measures to Control Workplace Accidents When Operating Electric Welding Machines

Controlling workplace accidents when operating electric welding machines is crucial to ensure the safety of workers and the work environment. Below are some measures:

• Training and Instruction: Provide comprehensive training on machine operation, safety rules, and emergency response. Ensure workers understand how to control and minimize risks.
• Use of Personal Protective Equipment (PPE): Ensure workers use all required PPE, including protective goggles, fire-resistant clothing, heat-resistant gloves, and safety shoes.
• Regular Machine Inspection: Conduct periodic inspections and maintenance of welding machines to ensure they operate safely. Report any malfunctions or defects to supervisors or technicians.
• Safe Work Environment: Keep the workplace clean, ventilated, and organized. Remove flammable materials and ensure no chemicals or toxic gases are present.
