Welder’s Update

By Sue McCraven

When acetylene and oxygen from pressurized cylinders meet a spark, a 6,000 F welding torch is created with a flame hot enough to melt through steel. Known as “hot work,” welders and pipefitters use regulated torches to cut or fuse pieces of metal. And as high temperatures, an ignition source, potential fumes and job site conditions are linked with the trade, a welding professional requires constant training, skill and safety awareness.

Technology is transforming the welding industry from an art to a technical and scientific trade with improved work conditions, thanks to health and safety regulations. This article is a refresher on safety and welding terms, but cannot cover all OSHA and American Welding Societyi (AWS) regulations and guidelines. According to AWS, the next edition of the Structural Welding Code – Reinforcing Steel D1.4, will be issued in late 2016 or early 2017, so specific code changes won’t be known for the next year while the draft is developed.

Safety when Welding

By Nick May

WelderIn welding and fabrication shops, the safety and welfare of employees is first and foremost. When welding, whether on large commercial projects, small local buildings or fabricating welded cages, many safety procedures must be considered before starting the project. This includes proper equipment that meets safety regulations; secure surroundings; an efficient workplace with appropriate lighting and comfortable temperature; easily accessed equipment and materials; and, of course, first aid and safety equipment.

OSHA outlines several regulations that pertain specifically to welding, and more than 25 states have their own specific regulations, so you should familiarize yourself and your crew with all pertinent standards. Here we will outline three areas that can help keep welders and others in the shop safe. Read More »

Hot Topic: Welding Reinforcement

Not all rebar is created equally.

By Claude Goguen, P.E., LEED AP

Proper practice in the welding of reinforcement is of particular importance in the precast industry. Welding of reinforcement can serve both as a means of expediting the production process and of creating material savings. However, it is important to exercise caution to ensure safe practices and to produce quality structural welds that maintain both steel strength and concrete structural integrity. From time to time, reports from NPCA plant certification audits point out some deficiencies related to welding reinforcement that center around three major requirements. Read More »

It’s not just about fumes.

Many safety articles have been dedicated to the issue of dangerous fumes in the welding process. In fact thousands of lawsuits have been filed across the country in recent years primarily against the manufacturers of welding rod and welders, but so far most of them have been cleared of responsibility.

Companies that use welding in the plant process also have been spared most of this litigation, but it is clear that, given the nature of our society and business today, this should never be taken for granted. As in all areas of safety, common sense, proper documented procedures and records, and knowledge of current safety regulations are the best course. Read More »
