These operations are generally found in facilities work, but can also be present in science research functions or Art Departments. OSHA requires that adequate controls and procedures are in place for hot work to be performed. (29 CFR 1910.252-255) SPECIFIC TYPES OF WELDING OPERATION HAZARDS. There are 3 basic types of welding operations:
Welding and grinding operations require the use of hazardous materials such as argon, oxygen, acetylene and nitrogen gases. Proper ventilation and personnel protective equipment (PPE) must be utilized to protect personnel from toxic fumes and vapors generated by welding and grinding operations. All hazardous materials
Among the PPE required for welding, brazing and cutting operations are eye protection and protective clothing. Eye protection must be worn to protect from bright lights, heat, UV light and flying sparks. Helmets, goggles and other eye protection must have lenses for exposure to welding, cutting or brazing.
Grinding is the most comprehensive and diversified of all machining methods and is employed on many materials—predominantly iron and steel but also other metals, wood, plastics, stone, glass, pottery and so on. The term covers other methods of producing very smooth and glossy surfaces, such as polishing, honing, whetting and lapping.
Welding-procedures convey the required information to the workers performing welding operations.. They also assist in controlling workmanship and consistency.. Welding Procedure Specifications (WPS) are detailed welding work instructions.. Their purpose is to explain in words and pictures the whole welding process for any production item.
All welding, cutting and grinding operations may be performed in a total welding enclosure or "welding box" that is sufficiently high to control sparks and includes a fire retardant cover over the top. Wind speeds must not exceed 30 …
Health hazards associated with welding, cutting and grinding include eye and face impacts, arc radiation, inhalation of certain airborne contaminants, noise, heat stress, repetitive stress injuries, electrocution, fire and compressed gases. This article will focus on the first four, with an emphasis on eye and face protection and the personal ...
Wear goggles for all grinding machine operations. Check grinding wheels for cracks (Ring Test Figure 5-11) before mounting. Never operate grinding wheels at speeds in excess of the recommended speed. Never adjust the workpiece or work mounting devices when the machine is operating Do not exceed recommended depth of cut for the grinding wheel or ...
MECHANICAL WELDING For mechanical pipe welding, 3/32" Mech notching wheels are recommended for grinding starts and stops. These wheels are thinner than standard pipe notching wheels, allowing the operator to grind the bead without widening or scarring the narrow J and K bevels. HOT PASS The next welding step is called the hot pass.
Grind in line with the material using smooth, even strokes rather than short, choppy strokes. This provides effective results with coated abrasives and bonded abrasives. • Avoid arm grinding. When you use only your arms to operate a grinding wheel, the wheel vibration can take a toll on your wrists and forearms.
Protect other employees from welding, cutting, or grinding operations. Use approved welding curtains or flash screen in and around active work areas. 3. Use care in removing safety glasses, face shields, and welding hoods so as not to cause residual dust particles to enter the eyes.
Grinding Machine Definition: A grinding machine is a production machine tool used in the manufacturing industry in which the grinding wheel is attached in the tool post and the workpiece is fixed to the work table and when the operation starts it removes the unwanted material to get the desired surface finish, correct size, and accurate shape of the workpiece.
protection for welding operations involving lasers. HOW TO AVOID EYE AND FACE INJURIES Select the proper protection for the job - including other work going on nearby. Eye and face protectors for welding and related tasks, such as grinding and chipping, should comply with the requirements of ANSI Z87.1. Look for labels or markings indicating
Tungsten grinding machines are new in the TIG welding world and welders are seizing the opportunity to improve the quality of their work. In addition to more professional outcomes, the machines offer improved safety levels. Recently, the machines gained a new wave of popularity in the industry as welders regard them as a necessity for experiencing electrode …

Welding operations can also produce toxic gases like carbon monoxide, nitrogen dioxides and ozone. In addition, welding or cutting operations conducted in the presence of chlorinated hydrocarbons in the form of solvents on the metals or in the air may produce hazardous levels of highly toxic phosgene and hydrogen chloride gases.
Problem Visible haze in the weld shop from welding, back gouging, and grinding operations. Solution 63 Flowtron Air Cleaners were installed for fully automated dust removal to drums on the floor. More About the Flowtron AC
flying metal, slag chips, grinding fragments, wire wheel bristles, and similar hazards, which can ricochet under the helmet. Choose a filter lens shade according to the Lens Shade Selector Chart in ANSI Z49.1 or AWS F2.2. Lens Shade Selector. Consult AWS Fact Sheet 31, Eye and Face Protection for Welding and Cutting Operations.
7.4 During welding operations, welders should wear welding hood with appropriate filter lens. 7.5 During grinding, both a face shield or welding hood with a flip or auto-darkening lenses, and safety glasses or spoggles should be worn at all times to protect eyes from flying debris, i.e., Double Eye Protection.
