Vee Gauge for High Frequency Welding of Tube & Pipe

The Vee Gauge has been developed for the precise measurement of small vee angle from one to five degrees.  The vee angle has two edges and one apex, where the two edges meet with each other.  The first application can be for high frequency welding of steel tube and pipe.

The Vee angle is an important parameter for High Frequency welding of steel tube and pipe.  First, it affects the quality of the weld; Secondly, it affects the power consumption in the welding process.

However, the vee angle can be difficult to measure.  One reason is that it is a small angle, usually in a range of 1 to 5 degrees; Another reason is the tight space surrounded with weld rolls,  induction coil or weld shoes; The third reason is the limited lighting on the shop floor.

One way that people have adopted is to use play dough.  Apply the dough to the vee and then measure the vee printed on the dough with a protractor.  Another way is to use a small twist drill, a tape measure, and a calculator and then do a trigonometry calculation.  These ways are "quick & dirty", not so accurate, not so quick, not so easy.

The newly developed Vee Gauge, as shown in the photo below, will revolutionize the way to measure the small vee angle.

(1) With the Vee Gauge, you can measure the vee angle accurately.  It has a resolution of 0.1 degree.

(2) With the Vee Gauge, you can measure the vee angle quickly.  It can be done in 10 seconds.

(3) With the Vee Gauge, you can measure the vee angle easily.  You simply slide the pin into the vee until it touches both edges of strip, and then read at the apex.  And the reading is directly in degree.

(4) It is built to last and comes with a life long warranty.  It is made of stainless steel and the pin is hardened to stand against the sharp strip edges.  It is Made in USA.

(5) It comes with the recommended vee angle for different tubing such as OCTG and Fire Protection, Stainless, and Structural.  It will help to reduce the scrap when the weld is critical.  One piece less scrap will recover your investment in this innovative instrument.

(6) It has two sides.  One side is for a right-hand mill and another side is for a left-hand mill.

(7) It measures any vee angle between (1) degree and (5) degree.  This basically covers the whole range of  the vee angle in the real world.

(9) It can be used for tube and pipe of 1-3/4" OD and above.

(10) The Vee Gauge can not only be used for the welded tube and pipe, but also for the precise measurement of any small vee angle from 1 to 5 degree.  The small vee must have an apex.
