Working in confined spaces. Permit-required confined spaces have to be ventilated. Workers have to be trained to exit and enter confined spaces properly, and should work in these spaces rarely as much as possible. You can learn more about the standards governing working in confined space here. ASSE emphasized on the fact that welding by itself is dangerous and has resulted to thousands of lawsuits in recent years.

Welding operators should carefully assess the weld joints to ensure there are no excessive gaps, as poor part fit-up can lead to issues like burn-through or distortion on all materials, but particularly when welding on materials like aluminum or stainless steel. Clamping or fixturing a part in the correct position is also a good practice to help protect materials like stainless steel against distortion or buckling. It is not uncommon for companies to overlook the importance of their MIG gun consumables.
As with filler metals, companies should also avoid the temptation to purchase less expensive, lower quality consumables. These typically do not last as long or perform as well as OEM products, leading to more downtime and greater costs to purchase replacements and change over consumables.

As with other parts of the welding operation, investing time and money in training can yield significant long-term benefits for companies. Not only do welding operators benefit individually from process and equipment training, but in many cases it can also help them optimize the welding operation for greater efficiency. Too, proper training can give companies a competitive edge over those who have less-skilled labor and it promotes greater teamwork among employees.
Typically, training opportunities are available through equipment and filler metal manufacturers or through welding distributors. In some cases, working with a local technical college can lead to training for specific applications and markets, allowing companies to bring in welding operators who are already trained for a given application and better promote their position in a given industry. Making mistakes is human nature, but with some careful consideration, it is easy to avoid some of the more common ones associated with running a welding operation. Measuring out long-term savings, versus cutting costs up front, is a particularly good way to avoid pitfalls that could lead to excessive downtime, quality issues or lost productivity.
With so many factors to monitor — equipment, weld procedures, filler metals and consumables — it's inevitable that mistakes will occur in most welding operations on any given day. Mistake No. For that reason, it may be possible to use a lower amperage MIG gun or one with a lesser duty cycle on some applications. Types of joints used for welding are butt, lap, corner, T, and edge.
Health and Safety Factors in Welding Operations
The type of joint to be created and the type of material to be used, among other considerations, will determine the type of welding process that will be used to complete the project. All welding processes can be broken down into the two following categories:.
Pressure Welding. Pressure welding is a process in which external pressure is applied to produce welded joints either at temperatures below the melting point, which is solid state welding, or at a temperature above the melting point, which is fusion state welding. The atoms are moved together to a distance that is equal to or less than the equilibrium inter atomic separation distance.
This type of welding process requires the two pieces being joined to be extremely clean and especially free of oxides and non metallic films which must be removed from the surfaces of the metals by wire brush, so as to ensure the strongest welded joint possible. Pressure welding techniques are used primarily on metals that are highly ductile or whose ductility increases with increasing temperatures.
Types of commonly used pressure welding processes in industrial applications are:. Fusion Welding. Fusion welding produces welded joints by localized heating of the edges of the base metals, above their melting temperature. A filler metal may or may not be used, and no external pressure is required.
