Embodiment 1

[0024] Such as figure 2 As shown, a method for welding an electric kettle utilizing laser welding technology in the present invention, the thickness of the spout of the present embodiment is 0.6mm, and the thickness of the kettle body is 0.4mm. The spout and body are made of stainless steel. The model of the laser welding machine selected in this embodiment is HWLW-300A. Before welding, clean the welding place.

[0025] Specifically include the following steps:

[0026] Step 1, place the electric kettle body that needs to be welded on the fixture, and the positioning is accurate and firm;

[0027] Step 2, put the spout at the junction with the kettle body;

[0028] Step 3: Obtain the welding route according to the arc of the kettle body and the spout, and set the required welding position of the spout and the focus position of the laser output by the laser welding machine, and output the corresponding welding shielding gas;

[0029] Step 4, according to the material thic...

Embodiment 2

[0039] Such as figure 2 As shown, the first embodiment is basically the same as the second embodiment, except that the output energy is 11.3J, the power is 220W, the frequency is 20Hz, the solder joint width is 1.2mm, and the peak current is 94A.

[0040] In this embodiment, the sealing performance welded out is the best.

Embodiment 3

[0042] Such as figure 2 As shown, the first embodiment is basically the same as the third embodiment, except that the output energy is 11.50 J, the power is 250 W, the frequency is 20 Hz, the solder joint width is 1.3 mm, and the peak current is 94 A.

Abstract

The invention discloses a method for welding an electric kettle by utilizing a laser welding technology. The method comprises the following steps of: 1) putting the kettle body of the electric kettle needing to be welded on a clamp; 2) putting a part to be welded at joint with the kettle body of the electric kettle; 3) obtaining a welding route according to the radians of the kettle body of the electric kettle and the part to be welded, setting the focusing point of the required welding part of the part to be welded and output laser of the laser welding machine, and outputting corresponding welding protective gas; 4) setting the output energy, power, frequency, welding-point width and current peak of the laser welding machine according to the material thickness of the kettle body of the electric kettle and the part to be welded; 5) moving the gun head of the laser welding machine to the part to be welded, outputting energy and carrying out welding along the welding route; 6) when welding to the tail end of the welding route, enabling the laser welding machine to stop energy output and enabling the welding gun to return to the original point; and 7) grinding the outer surface of the part to be welded. The method disclosed by the invention has the advantages of good sealing performance, high productivity and low cost.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a method for welding an electric kettle using the laser welding technology. Background technique [0002] A general electric kettle needs to be welded in two places, one is the welding of the kettle body and the spout, and the other is the welding of the kettle body and the heating plate. [0003] When welding the spout, there are generally two welding methods: silver tin welding and intensive spot welding. Silver tin soldering is to dissolve the silver tin wire by heating at high temperature to weld the spout to the body of the pot. The process of silver tin soldering is: welding spout, spout polishing, sandblasting, yellowing removal, cleaning and drying, silver tin soldering The disadvantages are: 1) The cost is high. The current market price of silver tin wire is about 310 yuan / kg, and the average dosage is about 0.001kg; the soldering water is about 75 yuan / kg, and th...
