Thước đo mối hàn model WGU-9M / Nhật Bản

Undercut depth/ Groove angle/ Inconsistent level
Height of fillet weld & bead weld/ Throat thickness of fillet
Root opening/ Plate thickness

Stainless steel(SUS420J2)

*Additional functions for measurement of 
  - external diameter of circular workpiece
  - swelling of pressure welded reinforcing iron
  - width of bead weld

*Bead stride width: 53mm
*Bevel angle range: 0-70
*Higher accuracy undercut measurement function

Provides quick way to measure the diameter of welded rebar to insure proper dimensions of weld seam.
Scale marked for material diameter (φ19, 20, 25, 29, 32) corresponding to various rebar diameters, and 
amount of expansion(1/4,1.0~1.6). You can quickly find the ratio by reading the intersection of the two 
scale lines.
