Three Best Practices of Welding While Utilizing Titanium

Understanding the best practices of welding from the titanium tube manufacturer is crucial, especially for small-scale businesses. Using titanium during welding can be tricky. For instance, if there are green, grey, blue, violet, or white colors in titanium after welding, it suggests atmospheric contamination exists. Ensuring welding is as per standard is essential for quality and safety.

Titanium is resistant to corrosion. It is light in weight compared to steel, more massive than aluminum, and robust than both of above. Titanium is inexpensive in the long term as it requires little maintenance, service, and repair. Titanium has various aerospace applications, chemical processes, medical, military, recreation, and metal finishing purposes.

Three best welding practices should be used.

  • First, it is necessary to guard the heat-affected area against the atmosphere until the temperature goes below 800 degrees. The titanium must not start to absorb oxides (nitrogen, hydrogen, oxygen, carbon) until the temperature goes down that median.

If they are ingested too soon, the weldment would be embrittled, and the piece delivered is pointless. A decent practice is to test a bit out first before welding the first titanium venture. The factors that permit great protecting gas inclusion ought to be verified before starting.

  • The second best practice is that the work area should be clean. Contamination can exist from several different sources. There is oil on cutting fluid, fingertips, dirt, lubricants, paint, and more. These can cause weld failure and embrittlement. The work zone should be free of debris, dust, and excess air movement that would hinder the gas shielding described above.
  • Third best practice, it is critical to use the right tools for titanium welding. A power source along with a high-frequency arc beginning, a post-flow shielding gas timer, an output of 250 amps, and remote amperage control abilities is the first and quite foremost and needed tool. Polarity must be set to straight.

A torch can be water or air-cooled, based upon personal equipment choices. Water-cooled torches are maneuverable, smaller, and welded at higher temperatures for an extended time. Water-cooled lights are straightforward, but air-cooled torches are less expensive.

For carrying required welding current, a 2pc seriated tungsten sized is adequate. A glass lens is needed to distribute and make gas flow smooth evenly. A cup alongside a diameter of at least 0.75-1 inch should be used while larger containers enable larger welds.

A trailing guard should stretch the length of the weldment. An electrode should stretch longer than normal to give extended gas coverage if using the trailing shield or larger cups. Usually, the electrode extends enough for access and visibility to the joint. This can be calculated as 0.5 times the diameter of the electrode.

Purge blocks are necessary to provide shielding gas coverage on the bottom and back of a joint. Several places make their purge blocks from stainless steel and porous copper sheet. The copper acts as a gas lens through evenly distributing gas. The blocks are loaded with stainless steel wool to make smooth gas flow even more.

Wrap Up

Having adequate equipment, keeping the work area clean, and using gas shielding correctly, titanium welding tasks will not have failure or embrittlement. These practices are crucial to ensure safety and quality. Welding titanium, in the beginning, will permit for low maint
