Welding Merrimack: Making Safe Repairs In New Hampshire
Go to: Previous Article Next Article
When we hear the word 'welding' most of us picture someone in a suit that resembles an old-fashioned deep-sea diving outfit, surrounded by flying sparks. This may be accurate in some ways, but welding Merrimack style is much more than simply heating something until it melts. The technical definition of this process calls it the joining of materials, usually metals or thermoplastics, under high heat. When workers add filler, a small liquid pool of hot material is formed. Used as a joint, the welded portion is often stronger than the original was once it cools.
Most work of this nature is done in a controlled environment such as an industrial shop, but there are many occasions where it is needed outdoors, under water, or even in the vacuum of airless space. Most open-air work uses a system called shielded arc welding. The same process is commonly used under water in the repair of ships, pipelines or offshore oil platforms. The Russians pioneered space repairs in 1969, and today astronauts can use laser, resistance, and friction methods to keep the space station together.
Forging a heated bond between two pieces of steel is not a new concept. Variations of different forms have existed for centuries. One of the first was called forge welding, and that is what blacksmiths were doing in their clanging shops in the pre-electricity days. Using a mallet, they would hammer heated sections of metal until they became permanently united. While this pounding method was picturesque and helped build upper body strength, it was not the most efficient way to get the job done.
Today, modern practices are employed wherever construction or machinery has come apart. The weld is a permanent way to fix fatigue cracks in building construction, or to join new sections of sheet metal in new construction. This process has been absolutely fundamental to the progress of life in the post-industrial age, and without it most of the modern necessities we enjoy, from cars to skyscrapers, would simply fall apart.
Such jobs are inherently dangerous. There is the constant risk of burns, both from the arc and the flying sparks. Each spark contains a glob of liquid metal with the potential to start a fire in flammable material. Other perils include the possibility of eye damage if a visor is not worn, shock from improperly prepared equipment, and in some cases radiation. It is not something to try at home unless you are thoroughly trained and willing to prepare properly.
Precautions to routinely take include making sure the work floor is dry, in order to avoid shock from the electrical equipment. Wear safety shoes with thick rubber soles that prevent an accidental ground. Leave a window open to allow any fumes to dissipate. Steer clear of fragments, and don't allow anyone to stand around watching you unless they are properly dressed for safety.
If this all sounds beyond your scope, consider having your job done by well-trained local individuals. Check the Internet for up-to-date listings of professionals who make welding Merrimack style both safe and cost effective. Even with the expense of special equipment, labor, and sometimes automation, having a job done right the first time is worth the money. And, you will not burn any fingers.
