Titanium trailing shielding nozzle
Titanium shielding gas trailing shield protects the hot weld area behind the arc with inert gas, prevents oxidation, and allows a defect-free cool-down.
Physical-Chemical Mechanism of Action
The titanium trailing shield nozzle sprays inert gas (e.g., argon) behind the arc to protect the hot weld area. This prevents oxidation of the metal and allows controlled cooling.
Metallurgical Relevance & Welding Risks
Without inert gas shielding, pores and cracks form in titanium material because the material oxidizes quickly at high temperature. The trailing shield nozzle prevents this oxidation and ensures defect-free cooling of the material.
Workshop Practice & Instructions
Use the titanium trailing shield nozzle when welding titanium materials. Make sure the inert gas is correctly sprayed and the area behind the arc is constantly shielded. Irregular or missing gas supply can lead to oxidation and cracks.
