  • The effect of welding current, welding arc length and gas flow rate on holographic interference fringe was investigated. During holographic interference test, the reasonable range of the welding parameters is presented, and the calculation of the holographic interferometric arc temperature field is enumerated. the results shown that when the welding current less than100 A, welding arc length 4 ~ 14 mm and protecting air flow less than 6 L/min, the clear of holographic interference fringes can be obtain. The influence degree of welding current (R1), welding arc length (R2) and the protection of gas flow (R3) on the number of interference fringes (N1) on the tungsten tip, the center of circle transverse diameter (d1) and that of the radial diameter (d2) are R2 > R1 > R3, R2 > R3 > R1 and R2 > R1 > R3.
