Porosity problems in welds
Porosity is a common problem when welding titanium and titanium alloys. The root cause of stomata is the result of the effects of hydrogen. The formation of pores in the weld metal mainly affects the fatigue strength of the joint.
The main technological measures to prevent pores are:
(1) The protection of neon gas should be pure, and the purity should not be less than 99.99%
(2) Thoroughly remove organic matters such as scale oil on the surface of the welding piece and the surface of the welding wire.
(3) Apply good gas protection to the molten pool, control the flow and velocity of argon gas, prevent turbulence, and affect the protection effect. (4) Correctly select the welding process parameters, increase the use of the deep pool residence time and the right to use the bubbles to escape, which can effectively reduce the pores.
Application
Titanium tube light weight, high strength, excellent mechanical properties. It is widely used in heat exchange equipment, such as tube heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and pipeline. Many in the nuclear industry use titanium tubes as standard for their units.

FAQ
1. Are you the manufacturing or trading company?
Real manufacturing company, started from 2001, nearly 20 years. With 2 sales teams for foreign trading business, started from 2008, more than 10 years experiences.
2. Do you have a dedicated R & D team? Can you design a product for us?
We have a dedicated technical team responsible for research and development. But most of titanium fittings are standard, we can follow ASTM or other you asked.
3. Can you provide samples? Is there a charge?
Samples can be provided for a fee.
4. What is your payment method?
We can accept T / T, LC, trade assurance order from alibaba.com. Samples are 100% prepaid. Orders for mass production are below 1000 USD, 100% prepaid, above 1000 USD, 30% prepaid, and 70% paid before delivery.
5. How long is your delivery time?
Inventory samples: within 3 working days Products for bulk orders: 25-30 days under normal circumstances.
6. After-sales products, how to deal with problems?
Based on our statistics for each year, the probability of problems with titanium products is around 0.8%. There are two main reasons for the problem:
1) Among the products that have problems, 93% are misplaced in pre-sales communication, and the product that the customer needs is not really clear.
2) 5% is an unexpected situation and the extension of the construction period.
3) 2% is the problem of transportation and packaging. During long-distance transportation, the packaging is damaged and the surface is damaged.
7. What is your company's response to the product in question?
1) Verify and blame for pre-sales communication issues. Compensation is handled according to the proportion of liability.
2) We are 100% responsible for problems caused by damaged packaging during transportation.
