Problems solved by technology

This method has the following shortcomings: (1) the effective utilization rate of the heat source cannot be measured when the plate is welded; (2) the difference between the simulated welding process and the actual welding is relatively far; (3) the outer surface of the copper tube is emitted to the The heat in the air cannot be absorbed by water, so the measurement accuracy is not enough
However, the Seebeck envelope calorimetry method also has certain disadvantages: (1) During the welding process, that is, the heat lost on the surface of the plate before the box lid is closed cannot be collected by the Seebeck envelope
(2) Since it takes a while for the heat of the plate to be completely absorbed by the envelope, the measurement time is relatively long and the efficiency is relatively low

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a device and method for measuring the effective utilization rate of argon tungsten arc welding welding heat source. Background technique [0002] Gas tungsten arc welding, commonly referred to as TIG welding, is an arc welding method that generates heat between a non-consumable electrode and the work piece. When argon tungsten arc welding is used for welding, the heat output by the welding machine cannot be completely absorbed by the base material to be welded during actual welding, and there is a certain loss. The heat absorbed by the welding plate is called the heat effectively used. The effective utilization of heat divided by the heat output of the welding machine is called the effective utilization of the heat source. [0003] At present, the effective utilization rate of argon tungsten arc welding heat source is given by various references in a range, and there is no acc...
