Titanium is a lightweight, strong, and corrosion-resistant metal. It is also non-toxic and non-magnetic, making it an ideal choice for medical implants and devices. However, due to its high melting point (approximately 1688 degree or 3066 degree F), welding titanium presents some challenges that must be addressed.

TIG welding uses a non-consumable tungsten electrode to produce the arc, while GTAW uses a consumable tungsten electrode. TIG welding is slower than GTAW but produces a cleaner weld with fewer defects.

Another method for welding titanium tubing is laser welding. This method uses a high-powered laser beam to melt the metal and join the two pieces. Laser welding is typically faster than TIG or GTAW but requires specialized equipment and expertise.

During welding, it is important to maintain a stable arc and a consistent welding speed. The welding torch should be angled at approximately 15-20 degrees from the perpendicular position.

Post-Welding Treatments

Once welding is complete, the tubing may require some additional treatments, such as stress-relieving or annealing. Stress-relieving involves heating the tubing to a specific temperature and holding it there for a set amount of time. This helps to reduce any residual stress that may have accumulated during welding.
