The second part of the measurement range and technical parameters of the welding inspection ruler
The third part of the welding test ruler use method
Measure the height of the flat weld: first align the undercut ruler to zero, and tighten the screws, and then slide the height gauge to contact the solder joint, and the indicated value of the height gauge is the height of the weld
Measure the height of fillet weld, use the working face of the ruler to close the weldment and the weld, and slide the height gauge to contact the other side of the weldment, look at the indicator line of the height gauge, and the indication value is the height of the weld.
Measuring fillet weld: The weld joint at 45° is the fillet weld thickness. First of all, the working surface of the main body is close to the weldment, and the sliding height gauge is in contact with the solder joint, and the value indicated by the height gauge is the thickness of the weld.
Measure the undercut depth of the weld: first align the height gauge with the zero position, and tighten the screws, and then use the undercut ruler to measure the undercut depth, and look at the indication value of the undercut ruler, which is the undercut depth.
Measure the width of the weld: first use the main body to measure the angle against one side of the weld, and then rotate the measurement angle of the multi-ruler against the other side of the weld, and see the indicated value on the multi-ruler, that is, the width of the weld.
Measure the groove angle of the weldment: according to the groove angle required by the weldment, use the main ruler to match the multi-purpose ruler. Look at the angle formed by the working face of the main ruler and the multi-ruler work, and the value indicated by the multi-ruler indicator line is the groove angle.
Measure the width of the weld: first use the main body to measure the angle close to the side of the weld, and then rotate the measurement angle of the multi-purpose ruler to the other side of the weld, and see the indication value on the multi-ruler, that is, the width of the weld.
Measure the assembly clearance: insert the multi-ruler between the two weldments, and see the value of the clearance gauge on the multi-ruler, which is the clearance value.
The fourth part of the maintenance of welding inspection ruler
1. The welding test ruler cannot be put together with other tools, so as not to cause scratches caused by deformation, blurred engraved lines, and affect accuracy.
2. It is not allowed to scrub the scale with banana water.
3. The gap ruler on the ruler should not be used as a tool.
