Welding is a joining process in which metals, or sometimes plastics, are heated, melted and mixed to produce a joint with properties similar to those of the materials being joined. There are over 70 different welding processes. The type of welding process used is related to the specific application.

The most common processes are:. Health hazards associated with welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet UV radiation.

Safety hazards associated with these processes include burns, eye damage, electrical shock, cuts, and injury to toes and fingers. Many of these hazards can be controlled with engineering controls, work practices and personal protective equipment PPE.

Type a word, a phrase, or ask a question. There are three main components needed to create a weld. These are: A heat source such as an electric arc, a flame, pressure, or friction.

The most common heat source is an electric arc. An arc is the physical gap between the end of the electrode and the base metal. The physical gap causes heat due to resistance of current flow and arc rays. The arc melts the metals to create the joint. Shielding, which is the use of gas, or another substance to protect the weld from air as the weld is being formed. Oxygen from the air makes welds brittle and porous. Filler material, which is the material used to join to the two pieces together. The joined metals can be different metals.

The joint is not as strong as a welded joint. The "filler"metals commonly used are lead-tin alloys. The joint is not as strong as a welded joint or a brazed joint. Metals can also be cut or separated by a flame or an electric arc, or removed by "gouging" with an electric arc.

Follow the hazards control hierarchy to reduce welding risks

Welding operations present several hazards to both those undertaking the activity and others in the vicinity. During the arc welding process, live electrical circuits are used to create a pool of molten metal. Therefore, when welding, you are at risk of experiencing an electric shock. These include welding:. When carrying out welding activities, you are likely to be exposed to loud, prolonged noises. This can be very damaging to the ears and can result in hearing impairment. Many factors can affect the severity of a flash burn injury, such as distance, duration and the angle of penetration.

Properly installed and used the arc welder is very safe, but if used improperly the operator can be exposed to a number of hazards including toxic fumes, dusts, burns, fires, explosions, electric shock, radiation, noise, and heat stress. Any of these hazards can cause injury or death. By following suggestions and guidelines in this pamphlet the risks can be greatly minimized.
