Low Cost Monitor for Welding Titanium and Stainless Steel

Titanium and stainless steel are both reactive alloys. When they are heated during the welding process, they will react with any air that is present, causing oxidation, which can lead to a loss of corrosion resistance properties. Shielding the metal with an inert gas is therefore crucial and one wa ...

Accurately Measure the Dew Point During Purging

During purging welders need to measure the oxygen content but also need to measure the ‘dew point'. The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly. Georgia Gascoyne, CEO for HFT® sai ...

Pipe Purging Monitor

What is Weld Purging? Weld Purging is the displacement of oxygen by an inert gas (usually argon) from the vicinity of a weld, before, during and after welding. It is crucial to displace the oxygen when welding many metals to help achieve oxide free, zero colour welds with no loss of corrosion resis ...

Save Time and Money with a High Quality Inflatable Purging System

When welding tubes and pipes made of alloys such as stainless, duplex and chrome, it is important to eliminate the oxygen internally with an inert gas. This will help prevent oxidation, discolouration and will ensure a good internal weld profile. Weld Purging long pipelines can be costly and time ...

Monitor your Titanium Welds for High Quality Results

Preventing oxidation when welding tubes and pipes can be achieved by purging the inside with an inert gas. This simple procedure saves both time and cost. By knowing the exact level of oxygen inside the pipe at all times, the welder knows when to start welding for high quality results. With restri ...

Weld Purging: Replace Foam with Film for High Quality Welds

The use of home made sponge foam purge dams for pipe weld purging is still very familiar throughout the welding industry. However, operators are unaware as to how the use of sponge foam can adversely influence the metallurgical strength of a joint. When sponge foam starts to warm up from the heat ...

Weld Purging: Replace Paper, Foam and other unsuitable Materials with Argweld® Weld Purge Dams

Weld Purging is essential when welding tubes and pipes made of reactive metals such as stainless steels, titanium and zirconium. Usually weld zones are confined with purge dams so that the use of argon purge gas is limited and waiting times are reduced. Homemade dams fabricated from paper, sponge ...

Welding of Vacuum Tubing and Piping

Welds in tubing and pipework for vacuum systems should have many important characteristics. They ideally need to be manufactured from stainless steel, leak tight, the joints should have full penetration with excellent sidewall fusion, there should be no porosity and the finish should be free from ox ...
