Gr 5 ERTi*6Al*4V Titanium Wire

The welding properties of titanium and titanium alloys have many remarkable characteristics, which are determined by the physical and chemical properties of titanium and titanium alloys. Through the continuous exploration of titanium and titanium alloy welding process specifications, as well as the reasonable analysis of the test process problems, summed up titanium and titanium alloy welding process characteristics and operation key points.

1. Influence of gas and impurity pollution on welding performance

1.1 Effect of hydrogen

1.2 The effect of oxygen

1.3 The effect of nitrogen

1.4 The impact of carbon

2, Welding joint crack problem

3, The porosity problem in the weld

3.1 Neon gas protection must be pure, the purity shall not be less than *9.*9%

3.2 Thoroughly remove organic matter such as oxidized skin oil on the surface of weldment and wire.

3.3 The molten pool should be provided with good gas protection, and the flow rate and velocity of argon should be controlled to prevent turbulent flow phenomenon and affect the protection effect.

3.4 Correct selection of welding process parameters, increase the residence time of deep pool to use the bubble escape, can effectively reduce the porosity.
