Description

A measuring tool capable of simultaneously measuring weld reinforcement and weld width of steel pipe

technical field

The utility model relates to a measuring tool, in particular to a comprehensive measuring tool suitable for simultaneously measuring the weld reinforcement and weld width of steel pipes. The utility model is especially suitable for the measurement of the inner and outer welds of large-diameter steel pipes such as UOE welded pipes and JCOE welded pipes. In addition, the utility model can be popularized and applied to weld seam measurements in the fields of plate welding and strip welding.

Background technique

The external dimensions of the weld seam of large-diameter welded pipes are one of the important factors for judging the quality of the weld seam, among which the reinforcement and width of the weld seam need to be quantitatively judged.

At present, the weld reinforcement is mostly measured with a dial indicator: first return to zero at the weld toe on one side, move the dial indicator laterally, and obtain the highest value a; then return to zero at the weld toe on the other side, and move the dial indicator to Divide the table, and get the highest value of b; finally get the reinforcement as (a+b)/2. This method is cumbersome to measure, and the dial indicator frame is much larger than the width of the weld. After welding, the steel pipe has local ellipticity, and it is impossible to accurately measure the height of the highest point of the weld from the weld toe.

Weld width is usually measured with a steel ruler and vernier calipers. When using a steel ruler, due to the protrusion of the weld seam, it cannot be accurately aligned with the weld toe, resulting in low measurement accuracy. When using a vernier caliper to measure, the accuracy can meet the measurement requirements, but because the measuring handle is too long, it interferes with the pipe wall when measuring the width of the inner weld, which cannot ensure accurate measurement of the weld width.

CN201016688Y discloses a direct-reading welding seam reinforcement measuring device. The device solves the problem of accurate measurement of steel pipe weld reinforcement. Including, two bases, which have positioning through holes in the axial direction of the body, and are connected by setting a positioning pin; It is accommodated in the through hole and leans against the guide rods of the two clamping parts; the measuring instrument is arranged between the two bases and is clamped and fixed by the two clamping blocks. In this way, the weld reinforcement value can be read directly to improve work efficiency.

However, the utility model can measure the weld reinforcement, but cannot measure the weld width at the same time, which causes inconvenience in on-site operation. Moreover, because the base is much larger than the width of the weld, the steel pipe has local ovality after welding, and it is impossible to accurately measure the height of the highest point of the weld from the weld toe.

Therefore, people look forward to a measuring tool that can be simplified and can simultaneously measure weld reinforcement and weld width, that is, a ruler has both measurement functions and is convenient to use. At the same time, people are also looking forward to improving the accuracy and precision of weld reinforcement measurement.
