Abstract

The invention discloses a plasma arc coaxial in-situ pointing calibration device and method, and relates to the technical field of plasma arc welding. The device includes a plasma torch, a three-way valve, a smoke generator and a colored gas pipeline; wherein the three-way The valve is installed on the side of the plasma gas pipeline of the plasma torch close to the nozzle, and the output end of the smoke generator is connected with the three-way valve through the colored gas pipeline. The method comprises three steps of turning on the smoke screen generator, calibrating the welding seam position and welding successively through the smoke screen generator. The invention has the advantages of simple equipment, low cost, precise adjustment, welding can be started immediately after adjustment, and solves the technical problem of inaccurate positioning of the plasma arc, welding bead and welding seam.

Description

technical field [0001] The invention relates to the technical field of plasma arc welding, in particular to a plasma arc coaxial in-situ pointing calibration device and method. Background technique [0002] Plasma welding is a high-energy welding method developed on the basis of tungsten-level argon arc welding. Tungsten grade argon arc welding is a free arc, while the plasma arc is a compressed arc, the arc is concentrated and the action area is small. Plasma welding has the characteristics of high arc temperature, energy concentration, strong penetration, fast welding speed, small heat-affected zone, and small stress deformation. It has been widely used in industrial production, especially in aerospace and other military and cutting-edge industrial technologies. Copper and copper alloys, titanium and titanium alloys, alloy steel, stainless steel, molybdenum and other metal welding and additive manufacturing fields. In many important parts, such as titanium alloy missile ...
