Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing technology is difficult to simultaneously measure the measurement of multiple parameters such as the size of the welding groove, the size of the fusion zone, and the depth of the weld, making it difficult to measure the weld bead in time during welding. The welding increases certain difficulty; at the same time, there are many impurities in the weld bead after welding, which is easy to affect the measurement accuracy.

Abstract

The invention discloses a welding groove measuring instrument, and belongs to the technical field of groove measuring instruments. The welding groove measuring instrument comprises a welding plate and further comprises a measuring plate, wherein a degree inclined plane and a boss horizontal plane are symmetrically arranged on the measuring plate and used for measuring the welding sizes of different positions respectively; the measuring rod is connected to the measuring plate in a sliding mode, and the two ends of the measuring rod are detachably connected with measuring heads for measurement. During measurement, the cleaning brush is driven to clean the surfacing position of the groove, dust or welding slag is prevented from influencing the measurement precision, dust is adsorbed during cleaning, dust is prevented from being inhaled into the body of a measurer, protection on the measurer is improved, meanwhile, the measuring plate can conduct measurement in multiple modes, so that different groove surfacing modes are measured; the measuring practicability of the measuring plate is improved, the device effectively meets the size measurement of various surfacing modes, measurement parameters are provided during welding, and meanwhile the measurement precision can be improved.

Description

technical field [0001] The invention relates to the technical field of groove measuring instruments, in particular to a welding groove measuring instrument. Background technique [0002] The welding process is one of the indispensable manufacturing links of major engineering equipment. In order to skillfully use welding deformation to obtain welded joints with regular shape and small welding residual deformation, multi-layer and multi-pass surfacing welding is usually used to weld the target object; the groove angle It is an important welding process factor that affects the shape of the weld seam, the welding dilution rate, and the shape of the fusion zone, and even affects the stability of the welding arc; [0003] In order to realize the optimal setting of welding process parameters, it is extremely important to accurately measure the welding groove and the characteristic size of the weld seam. If the size of the welding groove does not meet the requirements, it will cause...
