Trailing Shields

►TrailingShields.com has released a range of trailing shields. The trailing shields cover the area behind the torch with purge gas, preventing unwanted chemical reactions and helping to cool the weld pool.

►Trailing Shields Protect the hot weld from oxygen through purging is vital when welding metals including stainless steel and titanium. It is particularly important in the food and drinks and pharmaceutical industries, or in any safety-critical applications such as the motor sport industry.

►A number of problems can result from too much oxygen reaching welded metal before it has cooled adequately. These include oxidation, coking, discoloration and porosity. The practice of pickling to remove unwanted color and surface chemicals only removes impurities on the surface. It does not stop weld failure or the formation of pockets of unwanted material.

►Titanium is a reactive metal that absorbs oxygen, nitrogen, and hydrogen at temperatures above 800 degrees F. Protecting this alloy at elevated temperatures during welding can be achieved welding in a vacuum of at least 10-4 torr, purge chamber or in atmosphere using trailing / auxiliary shields.


►When using purge gas, normally argon, to protect welds from oxidation, the area of hot metal behind the torch is often ignored and this can lead to bad welds, often seen on larger pipes and thicker materials where the volume of hot metal means cooling takes place after the torch has passed. To overcome this problem, TrailingShields.com manufactures a range of trailing shields that cover the area behind the torch with purge gas, preventing unwanted chemical reactions and helping to cool the weld pool.

►A specially designed mesh inside the shield ensures excellent gas distribution.

►The cost of our trailing shields and trailing shield packages can often be justified by the saving from just one bad weld.
