How to Weld Titanium? The essential steps for titanium welding are similar to welding other metals but with a few changes. Welding steel may require 30% preparation and 70% welding whereas it is just the opposite in case of titanium welding: 70% preparation and 30% welding. Titanium can be welded by any experienced welder if he can control certain important elements. Eliminating the impurities on the material is first and foremost. To weld titanium it is very important to clean the material in a proper way. This can be achieved through chemical cleaning. All the surfaces must be cleaned in a proper way. The next factor to consider is the atmosphere. If air around titanium is contaminated there may be certain problems in welding. You can overcome this problem by using specialized equipment. Trailing cups can be used for short jobs but for production purpose vacuum controlled chamber would work. Chamber is expensive but it is a worthwhile investment. All these key elements are important for welding titanium in a proper way. Welding titanium is a very expensive process; so it is not recommended for anyone who may still be learning the art of welding.
