Welding Quality Controlling by Describing the Shape of Weld Joint of Pipeline Steel through Computer Software

Abstract:

The relationship between welding quality and the shape of weld joint of pipeline steel and the factors which can make large influence over the shape of weld joint is analyzed in this paper. The pictures of weld joint in all kinds of welding conditions are taken into computer by some special ways in order to the pictures can be used to producing mathematic curves of weld joint shape. Welding quality and the shape of weld joint of pipeline steel can be forecasted and controlled by finding the best mathematic curve among all the curves which are fitted from the pictures of the weld joint of pipeline steel in all kinds of welding conditions by the computer software.
