Abstract

The invention relates to an angle welding method of a stainless steel sheet on the basis of image processing, belonging to the technical field of metal welding. A welding quality control method comprises the following steps: image processing results are used for replacing the sensitive technological parameters of welding visual information, adjusting the position of a welding gun in real time andthe like to control welding quality; a welding clamp on which a clamp at one side is positioned at the horizontal position and forms an angle of 90 degrees to 180 degrees with a clamp at the other side is adopted to fix a sheet; a stepping motor controls the mobility of the clamp; an imaging processing algorithm is adopted to detect the position of a tungsten electrode; and the tungsten electrodeis adjusted to optimum parameter in real time according to results. The angle welding method greatly reduces reject rate, improves production efficiency, simultaneously has fast calculating speed andcontrollable calculation precision, is applicable to detection of other cylindrical images and has very wide application prospect in the welding image detection.

Description

technical field [0001] The invention relates to a method in the technical field of metal welding, in particular to an image processing-based fillet welding method for stainless steel sheets. Background technique [0002] Due to the small thermal conductivity, large linear expansion coefficient, and small self-constraint in the welding of stainless steel sheets, defects such as burn-through and welding deformation are prone to occur during welding. Therefore, the basic process requires small current and fast welding speed, which can reduce welding heat input and welding deformation. However, under the same specification parameters, which welding torch position and movement mode are more conducive to ensuring the quality of the weld, there are still relatively few researches at home and abroad. [0003] After searching the existing technology, it was found that Wang Liangyang et al. published "Electric Welding Machine" (2009, Vol.39, No.3: 77-79) "The Influence of Welder's Op...
