Product Introduction
Titanium alloy welding is a common method of metal welding. Titanium alloy has the characteristics of high strength, corrosion resistance, and lightweight. We are proud of our strict quality control testing to ensure that every pipe we produce meets or exceeds the highest industry standards. standard. We perform visual inspections, eddy current testing and other non-destructive testing to verify the quality of the tubing. Our pipes are also laboratory tested for chemical and physical properties to ensure they are safe, durable and reliable.

Process flow
Pre-welding preparation: Grind the joints and clean them strictly.
Preheating: Titanium alloy welding requires preheating. Generally, a preheating temperature of about 500°C is used. The preheating time is based on 220V, usually 30 minutes.
Welding mode: For the welding of titanium alloy pipes, the automatically adjusted constant pressure adjustable force arc length method is used.For titanium alloy plate welding, smaller welding current and voltage should be used, and the welding speed should be shortened as much as possible. Plasma arc welding adopts lift welding.
Formal welding:Install the connecting pieces and pipes and perform tungsten arc welding or plasma arc welding.
Interface cleaning:Clean and remove the rivet edges to make the welds flat.
Preheating: After completing the welding, repeat the above preheating process.
Cooling after welding: Cooling should be carried out above 220℃. If it does not reach 220℃ after welding, no cooling is allowed.
Repair and polishing: Arrange the welding seam incision and polish it.
