Welding is a process that joins two pieces of metal by heating them together until they melt and form a joint. Welding is often used to fix things that have been broken, but it can also be used to create new pieces of metal.
Welding can be done with a variety of metals, but the most common are steel and aluminum. The welding process begins by heating the metal until it is hot enough to melt. Then, the welders use a filler material to create a joint between the two pieces of metal. Finally, they cool the welded piece and make sure it is properly sealed.
There are a number of different welding techniques, but the most common are arc welding and gas welding. Arc welding is used to join pieces of metal that are close to each other, while gas welding is used to join pieces of metal that are far apart.
Both arc welding and gas welding use an electric current to heat the metal. The current causes the metal to melt and form a joint. Gas welding is also used to create joints between metal pieces that are too large for arc welding.
Welders need a variety of equipment to do their job properly. They need a welder’s torch, which is a device that uses heat to weld metals. They also need a filler rod, which is used to create the joint between the two pieces of metal. Welder’s gloves are essential for protecting your hands from the heat, and a face shield will protect your eyes from sparks and debris.
Defibrillator and Pacemaker in Welding
Defibrillators and pacemakers are often used in welding because they can cause a lot of heat. Welders need to be careful not to shock themselves or the object they are welding.
As a rule, it is advisable to work close to sources of electromagnetic radiation (from conventional welding equipment) to avoid dangerous situations. MMA (SMA), MIG/MAG (GMA), and TIG (GTA) devices are unlikely to pose a risk to pacemaker users, but it is advisable to reduce the exposure as much as possible.
When it comes to welding, unlike with other household power tools, we can experience a higher tendency to temporarily affect the functioning of your pacemaker or implantable defibrillator.
What are the safety concerns for welding?
When welding, there is a risk of sparks and molten metal flying into your eyes. Welders need to wear protective gear, including face shields and gloves. If you are using an arc welder, you also need to wear a full body suit.
If you are using a gas welder, you need to wear a gas mask and safety goggles. If you are using a TIG welder, you need to wear a full body suit and safety glasses.
Can welding affect your heart?
There is increasing evidence that welding fumes are associated with a greater number of cardiovascular events. In the past, several studies have shown that welders experience an increase in the mortality from ischaemic heart disease.
