What Is The Difficulty Of Welding The Pattern Aluminum Plate
May 09, 2018

The pattern aluminum plate is widely used in all kinds of welding structure products, mainly because it has light weight, high strength and good corrosion resistance.

No magnetism, good forming and low temperature performance. However, we will encounter some difficulties in welding decorative aluminum plates. How can we solve them?

Below, by jiangyin xinyouda aluminum industry co., LTD. To introduce the difficulty of the pattern aluminum plate welding?

(1) aluminum alloy welded joint has a severe softening and low strength coefficient, which is the biggest obstacle to the application of decorative aluminum alloy plate.

(2) it is easy to produce stomata in the welding of decorative aluminum alloy plates.

(3) aluminum alloy welding of decorative pattern is easy to produce hot crack.

(4) the alloy linear expansion coefficient is large and easy to produce welding deformation.

(5) the surface of pattern aluminum alloy is easy to produce refractory oxide film, which requires high power density welding technology.

(6) the thermal conductivity of the aluminum alloy plate is large, and the heat input is more than four times that of welding steel at the same welding speed.

Therefore, the welding process of the pattern aluminum plate mentioned above requires the efficient welding method with high energy density, small welding heat input and high welding speed.
