The suitable welding material and the rational welding parameters were confirmed by welding procedure test of high strength weather resistant steel. It was successfully applied to the production.

This equipment use long arc xenon lamp as light source imitate and strengthen weatherability accelerate ageing to get near air ageing test results quickly then evaluate the material weatherability.

Usually, corrosion resistance of weathering steels is evaluated by the weight-loss method in an accelerated corrosion test.
