Narrow Gap

It is submerged arc equipment specially designed for welding in narrow places, particularly for the nuclear and very heavy petrochemical industry.

In wide thickness walls (greater than two inches) making a bevel for a welding arc implies a lot of time, as well as material waste. Also the use of consumables is greater when welding with a V bevel. For that reason this joints are prepare with J bevel.

That is why narrow gap headers were developed. The arc is identical to a traditional one with the only difference in the welding torch, being this very large and thin. It can enter in spaces of less than ¾ inches and up to 6 inches depth. With this besides time saving, the input and base material waste is reduced.

For very depth applications it requires a special tracking joint device, because the operator is not able to see in such a small space.
